Background: Several authors highlighted the limitations of the Keros classification system in predicting intracranial entry risk. Recently, our group proposed a new classification system based on the angle formed between the lateral lamella of the cribriform plate (LLCP) and the continuation of an horizontal plane passing through the cribriform plate (Gera classification). The aim of this study was to analyze whether the risk of iatrogenic cerebrospinal fluid leak (CSF-L) was better predicted by Keros or Gera classification., Methodology: The pre-operative CT scans of 24 patients (CSF-L group) who suffered from iatrogenic CSF-L during endoscopic sinus surgery (ESS) were compared to those obtained from a group of 100 patients who underwent uneventful ESS (control group). The skull base measurements as well as the distribution of Keros and Gera classes in the 2 groups were analyzed., Results: No difference in the distribution of Keros classes or in the depth of the cribriform plate between CSF-L and control group were demonstrated. On the contrary, significant differences in the distribution of Gera classes and in the degree of the angle formed by the LLCP and the continuation of the horizontal plane passing through the cribriform plate were found. In particular, according to Gera classification system, 19 out of 24 patients in the CSF-L group were considered at risk for iatrogenic CSF-L., Conclusions: Gera classification system might be more sensitive to anatomical variations associated with CSF-L than the Keros one, further suggesting the application of the former during the preoperative CT scan evaluation.

Background: The aim of this study is to propose a classification of the angle formed by the lateral lamella of the cribriform plate (LLCP) and the horizontal plane passing through the cribriform plate. In particular, the angle was classified into class I (over 80 degrees), class II (45 to 80 degrees, and class III (under 45 degrees) METHODOLOGY: A total of 190 computed tomography scans were retrospectively reviewed in order to obtain four sets of measurements. 1) depth of the cribriform, 2) angle, 3) length of the LLCP, 4) width of the fovea ethmoidalis. The relationship among these measurements were analyzed., Results: The angle was significantly correlated with the depth of the cribriform and the length of the fovea, while it was negatively correlated with the length of the LLCP. Significant negative correlation was also found between the length of the LLCP and the width of the fovea., Conclusions: This angle classification is based on the theoretical risk of iatrogenic injuries, but it could be helpful also in clinical practice by providing indirect information on the thickness of the anterior skull base. As the angle decreases, in fact, the portion of the anterior skull base composed by the LLCP, increases.

Increased knowledge regarding the heterogeneity of Prostate Cancer (PC) and its variable outcomes has generated controversy over the best clinical approach. Nowadays, it is well-known that patient outcomes and clinical management may be improved by an efficient organization of the national health care system. The Interdisciplinary Group for Oncological Care (GICO) for PC patients was created by our healthcare management company in September 2010. Since then, a multidisciplinary internal report was applied to PC patients. This report highlights our methodology and experience of planning a GICO, and illustrates the results obtained for the management of PC patients before and after the adopted GICO criteria in a single institution, the SS Annunziata Hospital (Chieti, Italy).

The purpose of this cephalometric study was to evaluate the craniofacial changes induced by functional treatment of mandibular advancement with special regard to pharyngeal sagittal airway dimensions, tongue and hyoid bone position in subjects with sleep-disordered breathing (SDB) and dentoskeletal Class II malocclusions compared with an untreated Class II control group. 51 subjects (24 female, 27 male; mean age 9.9 ± 1.3 years) with Class II malocclusion and SDB consecutively treated with a functional appliance (Modify Monobloc, MM) were compared with a control group of 31 subjects (15 males, 16 females; mean age 10.1 ± 1.1) with untreated Class II malocclusion. For the study group, mode of breathing was defined by an otorhinolaryngologist according to complete physical examination. The parents of all participants completed a modified version of the paediatric sleep questionnaire, PSQ-SRBD Scale, by Ronald Chervin (the Italian version in 22 items form) before and after the trial. Lateral cephalograms were available at the start and end of treatment with the MM. Descriptive statistics were used for all cephalometric measurements in the two groups for active treatment changes. Significant, favourable skeletal changes in the mandible were observed in the treated group after T2. Significant short-term changes in sagittal airway dimensions, hyoid position and tongue position were induced by functional therapy of mandibular advancement in subjects with Class II malocclusion and SDB compared with untreated controls. After orthodontic treatment, a significant reduction in diurnal symptoms was observed in 45 of the 51 participants who had received an oral appliance. Orthodontic treatment is considered to be a potential therapeutic approach for SDB in children. Orthodontists are playing an increasingly important role in managing snoring and respiratory problems by oral mandibular advancement devices and rapid maxillary expansion., (© Copyright by Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale, Rome, Italy.)

Objectives: To evaluate the reliability and validity of the Italian Voice Symptom Scale (I-VoiSS)., Study Design: Cross-sectional, nonrandomized, prospective study with controls., Methods: The study consisted of five phases: item generation, reliability analysis, normative data generation, validity and responsiveness analysis. A group of 113 dysphonic patients was enrolled for the internal consistency analysis. Seventy-three of them completed the I-VoiSS twice, 2 weeks apart, for test-retest reliability analysis. A group of 150 vocally healthy participants completed the I-VoiSS for normative data generation. I-VoiSS scores obtained by dysphonic and vocally healthy participants were compared for validity analysis. I-VoiSS scores were correlated with those of the Italian version of the Voice Handicap Index (I-VHI) in 49 dysphonic patients for criterion validity analysis. I-VoiSS scores obtained in a group of 37 nonsmoker dysphonic patients before and after surgical treatment for vocal fold polyps were compared for responsiveness analysis. Finally, the cutoff value of the I-VoiSS was calculated., Results: All the enrolled participants managed to complete the I-VoiSS autonomously. Internal consistency and test-retest were satisfactory (α = 0.92 and r = 0.91). A significant difference in the I-VoiSS scores between the dysphonic and vocally healthy participants was found (p = 0.001). Positive significant correlations were found between I-VoiSS and I-VHI scores (r = 0.85). I-VoiSS scores obtained in the pretreatment condition were significantly higher than those obtained after surgery (p = 0.001). The cutoff value of I-VoiSS was 15.5., Conclusion: I-VoiSS is reliable, valid, responsive to changes, and recommended for clinical practice and outcome research., (Copyright © 2017 The Voice Foundation.

Recent technological improvements in head and neck field have changed diagnostic and therapeutic strategies for salivary disorders. Diagnosis is now based on colour Doppler ultrasonography (US), magnetic resonance (MR) sialography and cone beam 3D computed tomography (CT), and extra- and intracorporeal lithotripsy, interventional sialendscopy and sialendoscopy-assisted surgery are used as minimally invasive, conservative procedures for functional preservation of the affected gland. We evaluated the results of our long-term experience in the management of paediatric obstructive salivary disorders. The study involved a consecutive series of 66 children (38 females) whose obstructive salivary symptoms caused by juvenile recurrent parotitis (JRP) (n = 32), stones (n = 20), ranula (n = 9) and ductal stenosis (n = 5). 45 patients underwent interventional sialendoscopy for JRP, stones and stenoses, 12 a cycle of extracorporeal shockwave lithotripsy (ESWL), three sialendoscopy-assisted transoral surgery, one drainage, six marsupialisation, and two suturing of a ranula. Three children underwent combined ESWL and interventional sialendoscopy, and seven a secondary procedure. An overall successful result was obtained in 90.9% of cases. None of the patients underwent traditional invasive sialadenectomy notwithstanding persistence of mild obstructive symptoms in six patients. No major complications were observed. Using a diagnostic work-up based on colour Doppler US, MR sialography and cone beam 3D TC, children with obstructive salivary disorders can be effectively treated in a modern minimally-invasive manner by extracorporeal and intracorporeal lithotripsy, interventional sialendoscopy and sialendoscopy-assisted transoral surgery; this approach guarantees a successful result in most patients, thus avoiding the need for invasive sialadenectomy while functionally preserving the gland., (© Copyright by Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale, Rome, Italy.)

Interventional sialendoscopy has become the predominant therapeutic procedure for the management of obstructive salivary disorders, but only a few multicentre studies of large series of patients with a long-term follow-up have been published. This Italian multicentre study involved 1152 patients (553 females; mean age 50 years) who, after at least a clinical and ultrasonographic evaluation, underwent a total of 1342 diagnostic and interventional sialendoscopies, 44.6% of which involved the parotid gland. 12% (n = 138) of patients underwent multiple treatments. The procedure was successful in 1309 cases. In 33 cases (2.4%) the procedure could not be concluded mainly because of complete duct stenosis (21 cases). Salivary stones were the main cause of obstruction (55%), followed by ductal stenosis and anomalies (16%), mucous plugs (14.5%) and sialodochitis (4.7%). Complete therapeutic success was obtained in 92.5% of patients after one or more procedures, and was ineffective in < 8%. Untoward effects (peri and postoperative complications) were observed in 5.4% of cases. Sialendoscopy proved to be an effective, valid and safe procedure in the diagnostic and therapeutic management of non-neoplastic obstructive salivary gland diseases., (© Copyright by Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale, Rome, Italy.)

Objectives: The aim of this study was to determine the prevalence and clinical characteristics of voice disorders in a large group of patients seeking voice therapy., Study Design: This is a prospective prevalence study., Methods: A total of 821 patients were enrolled. Each patient was evaluated following a multidimensional protocol including videolaryngostroboscopy, perception, acoustics, aerodynamics, and self-rating by the patient. Data regarding age, gender, tobacco use, gastroesophageal reflux disease (GERD), and professional voice use were collected and analyzed., Results: Based on videolaryngoscopic findings, the sample group was divided into patients with functional dysphonia (n = 155), patients with organic dysphonia (n = 359), and patients with dysphonia due to movement disorders (n = 307). The most frequently detected pathologies were vocal fold paralysis, muscle tension dysphonia, and vocal fold edema. Children (n = 41) and adolescents (n = 43) represented a minority of the sample group. Dysphonia was significantly more common in women. Organic dysphonia was more common in children and adolescents. GERD was suspected in 382 patients and confirmed in 83 of them; 164 patients were smokers. Professional voice users composed the large majority of the working population and were more frequently affected by organic dysphonia. Patients with dysphonia due to movement disorders presented a worse voice quality and voice-related quality of life., Conclusions: In patients seeking voice therapy, there are more females than males, children and adolescents represent a minority of the sample, professional voice users more commonly present organic dysphonia, and patients with dysphonia due to movement disorders show significantly worse voice quality., (Copyright © 2016 The Voice Foundation.

Introduction: This study was performed to evaluate the correlation between the objective and subjective sensation of nasal patency, assessed through a validated questionnaire, the Italian version of the NOSE scale, and the rhinomanometric results in a large cohort of patients complaining about nasal obstruction., Materials and Methods: Data was obtained from a total of 233 adult patients, (123 males, 110 females, with a mean age of 43.7 years) with a diagnosis of septal deviation and complaining about nasal obstruction. Anterior active rhinomanometry was used for objective assessment, while the I-NOSE scale and a visual analog scale (VAS) were used for subjective evaluation., Results: Positive correlations between I-NOSE scores and VAS and rhinomanometric results were found. The higher correlation was demonstrated between the HUNR (higher unilateral nasal resistance) parameter of rhinomanometry and the second item of the I-NOSE scale (Nasal blockage or obstruction). No significant correlation was found between the fourth item of the I-NOSE (Trouble sleeping) and the VAS score. The VAS score appeared mildly, but still significantly, correlated with the HUNR parameter of rhinomanometry., Conclusion: The correlation between the subjective sensation of nasal patency and the rhinomanometric data proved to be significant. No correlation between subjective sensation of trouble sleeping and rhinomanometric assessment was found. In counselling with patients complaining of nasal obstruction trouble in sleeping should not be considered as a symptom related to nasal obstruction.

The NCIQ is a quantifiable self-assessment health-related quality of life instrument specific for cochlear implant users. The aim of this study was to culturally adapt the NCIQ into Italian (I-NCIQ). A prospective instrument validation study was conducted. Cross-cultural adaptation and validation were accomplished. Cronbach α was used to test internal consistency in 51 CI users and in a control group composed by 38 post-lingual deaf adult on a waiting list for a CI. ICC test was used for test-retest reliability analysis. Kruskal-Wallis test with Mann-Whitney post hoc were used to compare the I-NCIQ scores in CI users before and after the cochlear implantation and in control patients. I-NCIQ scores obtained in CI users were compared with the results of Italian version of disyllabic testing without lip-reading and without masking. Good internal consistency and good test-retest reliability were found. I-NCIQ scores obtained in the 51 CI users after implantation were consistently higher than those obtained before implantation and in the control group. Moreover, no differences were found in the results of I-NCIQ obtained in the group of 51 CI users before implantation and in the group of control patients on post hoc Mann-Whitney analysis. Positive correlations between I-NCIQ scores and the results of disyllabic testing without lip-reading and without masking were found. The I-NCIQ is a reliable, valid, self-administered questionnaire for the measurement of QOL in CI users; its application is recommended.

Multiple chemical sensitivity (MCS) is a chronic disorder characterized by a variety of symptoms associated with the exposure to chemicals at a concentration below the toxic level. Previous studies have demonstrated peculiar responses in brain activity in these patients with respect to sensory stimuli while the association between chemical sensitivity and other environmental intolerances such as noise sensitivity has been questioned by researchers. In this study, a cohort of 18 MCS patients underwent transient-evoked otoacoustic emission (TEOAE) testing with and without contralateral suppression to evaluate the functionality of the medial olivocochlear (MOC) reflex involved in speech-in-noise sensitivity. Results were compared with an age- and gender-matched control group (n = 20) and correlation analysis with disease onset and quick environmental exposure sensitivity inventory (qEESI) symptom severity scale was performed. Subjects affected by MCS showed statistically significant impairment of MOC reflex, and the onset of the disease and several symptom subscales showed to be correlated to such reduction in some of the frequencies tested. These data suggest that alterations of MOC reflex could be part of the complex features of this disease although more studies are needed to further explore auditory perception disorders in environmental intolerances.

Background: Hemangiopericytomas (HPCs) are soft tissue tumors with histological variability and unpredictable clinical and biological behavior. HPCs in the head and neck are uncommon, the growth pattern is nonspecific; thus, diagnosis is often made by exclusion., Methods: A 43-year-old man complained of a short history of right ear pain associated with a growing mass in the right external auditory canal. Subsequent hearing loss in the right ear brought the patient to undergo a CT scan and an MRI. The relevant literature was also reviewed., Results: The imaging revealed a neoplasm arising from the floor of the right external auditory canal. The neoplasm was removed with the diagnosis of HPC., Conclusion: The literature reports few cases of HPC of the external auditory canal. Their rarity in this area leads to difficulties in diagnosis. Morphology is not predictive of their behavior, so close follow-up is mandatory for their correct management., (© 2016 Wiley Periodicals, Inc.)

Vestibular neuritis (VN) is one of the most common causes of vertigo and is characterised by a sudden unilateral vestibular failure (UVF). Many neuroimaging studies in the last 10 years have focused on brain changes related to sudden vestibular deafferentation as in VN. However, most of these studies, also due to different possibilities across diverse centres, were based on different times of first acquisition from the onset of VN symptoms, neuroimaging techniques, statistical analysis and correlation with otoneurological and psychological findings. In the present review, the authors aim to merge together the similarities and discrepancies across various investigations that have employed neuroimaging techniques and group analysis with the purpose of better understanding about how the brain changes and what characteristic clinical features may relate to each other in the acute phase of VN. Six studies that strictly met inclusion criteria were analysed to assess cortical-subcortical correlates of acute clinical features related to VN. The present review clearly reveals that sudden UVF may induce a wide variety of cortical and subcortical responses - with changes in different sensory modules - as a result of acute plasticity in the central nervous system., (© Copyright by Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale, Rome, Italy.)

Objective: To assess whether three-dimensional morphometric parameters could be useful in nasal septal deviation (NSD) diagnosis and, secondarily, whether CBCT could be considered an adequate imaging technique for the proposed task., Methods: We analysed images of 46 subjects who underwent CBCT for reasons not related to this study. Two experienced operators divided all the images into healthy and NSD subjects. Subsequently, the images were segmented using ITK Snap in order to obtain the three-dimensional model of the nasal airways and compute four morphological parameters: septal deviation angle (SDA), percentage of volume difference between right and left side of the nasal airways, nasal airway total volume and a new synthetic septal deviation index (SDI). Principal component analysis (PCA) was used to unveil relationships between each variable and the global nasal airway variability., Results: Differences between the groups were found in SDA (p < 0.001), in volume percentage difference (p < 0.05) and in SDI (p < 0.001). PCA showed high correlation between the SDI and the first principal component (0.97, p < 0.001)., Conclusions: Among the analysed parameters, SDI seemed to be the most suitable for the quantitative assessment of NSD, and CBCT allowed accurate assessment of airway morphology.

OTX proteins, homologs of the Drosophila orthodenticle (Otd), are important for the morphogenesis of the neuroectoderm, and for the central nervous system formation. OTX1 and OTX2 are important for the cochlea and macula development, indeed when OTX1 is knocked down, these organs undergo developmental failure. Moreover OTX2 transfection revert this effect in OTX1(-/-) mice. The TA isoform of TP63, involved in Notch regulation pathway, has a critical function in the cochlear neuroepithelium differentiation. TAp63 positively regulates Hes5 and Atoh1 transcription. This pathway has been also demonstrated in p63(-/-) mice, and in patients p63 mutated, affected by Ectodermal Dysplasia (ED, OMIM 129810). These patients are affected by mild sensorineural deafness, most likely related to the mutation in p63 gene impairing the Notch pathway. We demonstrated the role of OTX2 on TAp63 regulation necessary for the correct formation of macular neuroepithelium and we confirmed the impairment of vestibular function caused by p63 mutations. Although the abnormalities found in our patient were still at a subclinical extent, aging could exacerbate this impairment and cause a decrease in quality of life.

Chondrosarcoma is a malignant mesenchymal tumour of cartilaginous origin. It represents 11% of all malignant primary bone tumours, and the pelvis, ribs, femur and humerus are most frequently involved. Chondrosarcoma of the head and neck region is a rare disease, and represents approximately 0.1% of all head and neck neoplasms. This report describes a rare localisation of chondrosarcoma in a 56-year-old man who presented with swelling in the right preauricular area and mild limitation and pain in the mouth opening. Since 1959, just a few cases of temporomandibular joint (TMJ) chondrosarcoma have been described. Computed tomography revealed a large mass (39 x 46 x 40 mm) in the right preauricular and parotid region with morpho-structural alterations of the condyle and an intense periostotic reaction. The tumour was treated by total parotidectomy and condylotomy. The VII cranial nerve was preserved. Histopathologic examination revealed a low grade chondrosarcoma with a 50% proliferation index. At present, the patient is still receiving routine follow-up after radiotherapy and physiotherapy.

Background: The purpose of this study was to report preliminary long-term outcomes after supratracheal laryngectomy (STL)., Methods: Twenty-two male patients who underwent STL were involved in this study. Swallowing skills, neoglottis motility, and vibrations were videoendoscopically assessed. Aerodynamic measures, spectrogram analysis, aspiration pneumonia, body weight variations, and voice perceptual assessment were performed. Generic, voice-related, and swallowing-related quality of life (QOL) were assessed., Results: Aspiration was found in 10, 2, and 5 patients, respectively, for liquids, semisolids, and solids. Neoglottis motility was generally preserved, whereas vibration was impaired. Aerodynamic measures showed a poor performance. Perceptual assessment revealed highly dysphonic voices. In only 8 patients, a harmonic structure was visible in the spectrograms. Aspiration pneumonia occurred in 2 patients. Preoperative weight was maintained in 16 patients. Generic, voice-related, and swallowing-related QOL revealed satisfied patients., Conclusion: After STL, swallowing was sufficiently restored and QOL was satisfactory, whereas the voice was severely impaired even if oral communication was well preserved., (© 2014 Wiley Periodicals, Inc.)

GlideScope(®) is a recently developed videolaryngoscope that helps to achieve a good view of the laryngeal inlet and the vocal cords. Videolaryngoscopy has been proven effective in patients with unusual anatomical or pathological features, suggesting the possibility of a difficult endotracheal intubation. This device may also be useful for otorhinolaryngologists by facilitating access to the larynx and tongue base, especially in selected cases, where good visualisation of disease-altered structures is vital. According to the current literature, GlideScope(®) has been used for surgical procedures involving the tongue base, such as biopsies, foreign body removal and radiofrequency treatment of obstructive sleep apnoea. We believe that the use of this kind of videolaryngoscopy might be also indicated for laryngeal surgery as a valid alternative to the placement of a direct laryngoscope. This technique, especially in those cases with anatomical issues or important comorbidities, may be preferred to ambulatorial flexible or rigid laryngoscopy, and in planning surgical procedures in "difficult" patients due to the operating room setting comprising constant anaesthesiological support. In our experience, we performed five procedures involving the larynx with the GlideScope(®) in patients presenting unusual clinical characteristics that potentially compromised surgical outcome. No complications related to videolaryngoscopy were found. We recommend the use of GlideScope(®) for small surgical procedures involving the larynx in selected patients.

Glutathione transferases (GSTs) are a superfamily of detoxifying enzymes over-expressed in tumor tissues and tentatively proposed as biomarkers for localizing and monitoring injury of specific tissues. Only scarce and contradictory reports exist about the presence and the level of these enzymes in human saliva. This study shows that GSTP1-1 is the most abundant salivary GST isoenzyme, mainly coming from salivary glands. Surprisingly, its activity is completely obscured by the presence of a strong oxidizing agent in saliva that causes a fast and complete, but reversible, inactivation. Although salivary α-defensins are also able to inhibit the enzyme causing a peculiar half-site inactivation, a number of approaches (mass spectrometry, site directed mutagenesis, chromatographic and spectrophotometric data) indicated that hypothiocyanite is the main salivary inhibitor of GSTP1-1. Cys47 and Cys101, the most reactive sulfhydryls of GSTP1-1, are mainly involved in a redox interaction which leads to the formation of an intra-chain disulfide bridge. A reactivation procedure has been optimized and used to quantify GSTP1-1 in saliva of 30 healthy subjects with results of 42±4 mU/mg-protein. The present study represents a first indication that salivary GSTP1-1 may have a different and hitherto unknown function. In addition it fulfills the basis for future investigations finalized to check the salivary GSTP1-1 as a diagnostic biomarker for diseases.

Intraoperative nerve monitoring (IONM) aimed at reducing the injuries of recurrent laryngeal nerve during thyroidectomy is controversial. We conducted a meta-analysis to assess the incidence of nerve injuries with or without IONM. Studies published from January 1994 to February 2012 in English language on humans were identified. Heterogeneity of studies was checked by the Higgins test. Summary estimates of predictive values of injury were made using the Mantel-Haenszel test based on the fixed-effects model. Publication bias was assessed by a funnel plot and Egger's method. Eight articles were selected accounting a total of 5257 nerves at risk. IONM revealed a significant impact in preventing transient injuries (positive predictive value = 5% [95% CI: 2-8], negative = 96% [95% CI: 91-100], relative risk = 0.73 [95% CI: 0.54-0.98], p = 0.035), whereas they failed to demonstrate effect on permanent injuries (positive predictive value = 2% [95% CI: 0.6-3.8], negative 99% [95% CI: 97-100], relative risk = 0.73 [95% CI: 0.44-1.23], p = 0.235). This meta-analysis demonstrated the merit of IONM in preventing transient injury during thyroidectomy. No advantage was found in permanent injuries.

Aim: To report our experience on implementation and preliminary results of a decision-making model based on the recommendations of an Interdisciplinary Oncological Care Group developed for the management of colorectal cancer., Patients and Methods: The multidisciplinary team identified a reference guideline using appraisal of guidelines for research and evaluation (AGREE) tool based on a sequential assessment of the guideline quality. Thereafter, internal guidelines with diagnostic and therapeutic management for early, locally advanced and metastatic colonic and rectal cancer were drafted; organizational aspects, responsibility matrices, protocol actions for each area of specialty involved and indicators for performing audits were also defined., Results: The National Institute for Health and Care Excellence (NICE) UK guideline was the reference for drafting the internal guideline document; from February to November 2013, 125 patients with colorectal cancer were discussed by and taken under the care of the Interdisciplinary Oncological Care Group. The first audit performed in December 2013 revealed optimal adherence to the internal guideline, mainly in terms of uniformity and accuracy of perioperative staging, coordination and timing of multi-modal therapies. To date, all patients under observation are within the diagnostic and therapeutic course, no patient came out from the multidisciplinary "path" and only in 14% of cases have the first recommendations proposed been changed. The selected indicators appear effective and reliable, while at the moment, it is not yet possible to assess the impact of the multidisciplinary team on clinical outcome., Conclusion: Although having a short observation period, our model seems capable of determining optimal uniformity of diagnostic and therapeutic management, to a high degree of patient satisfaction. A longer observation period is necessary in order to confirm these observations and for assessing the impact on clinical outcome.

Angioedema attacks, characterized by the transient swelling of the skin and mucosae, are a frequent cause of visits to the emergency department. Swellings of the oral cavity, tongue, or larynx can result in life-threatening airway obstruction, while abdominal attacks can cause severe pain and often lead to unnecessary surgery. The underlying pathophysiologic process resulting in increased vascular permeability and plasma extravasation is mediated by vasoactive molecules, most commonly histamine and bradykinin. Based on the mediator involved, distinct angioedema forms can be recognized, calling for distinct therapeutic approaches. Prompt recognition is challenging for the emergency physician. The low awareness among physicians of the existence of rare forms of angioedema with different aetiologies and pathogenesis, considerably adds to the problem. Also poorly appreciated by emergency personnel may be the recently introduced bradykinin-targeted treatments. The main objective of this consensus statement is to provide guidance for the management of acute angioedema in the emergency department, from presentation to discharge or hospital admission, with a focus on identifying patients in whom new treatments may prevent invasive intervention.

The NOSE scale is a questionnaire assessing QOL related with nasal obstruction. The aim of this study was to culturally adapt the NOSE scale into Italian (I-NOSE). Prospective instrument validation study. Cross-cultural adaptation and validation were accomplished. Cronbach α was used to test internal consistency in 116 patients complaining nasal obstruction and 232 asymptomatic subjects. Pearson and ICC tests were used for test-retest reliability analysis. Normative data were gathered from the 232 asymptomatic subjects. Mann-Whitney test was used to compare the I-NOSE scores in patients and asymptomatic subjects and in 40 patients before and after septoplasty. I-NOSE scores obtained in 60 patients were correlated with rhinomanometric results and with the score of a visual analog scale (VAS) measuring the subjective sensation of nasal obstruction. Good internal consistency and good test-retest reliability were found. I-NOSE mean score of the normal cohort was 12.1 ± 13.2. Asymptomatic subjects scored lower than patients with nasal obstruction (p = 0.001). Positive correlations between I-NOSE scores and VAS and rhinomanometric results were found. The mean I-NOSE score improved from 64.4 ± 23.6 to 22.1 ± 13.5 after septoplasty (p < 0.001). The I-NOSE scale is a reliable, valid, self-administered, symptom-specific questionnaire; its application is recommended.

Background: The Self-Evaluation of Communication Experiences after Laryngeal Cancer (SECEL) questionnaire assesses the impact of total laryngectomy on communication-related quality of life (QOL). This study evaluates the Italian version of the SECEL (I-SECEL), including reliability, concurrent validity, and differences in scores between patients who undergo either total laryngectomy or partial laryngectomy., Methods: Eighty patients who underwent either total laryngectomy or partial laryngectomy completed the I-SECEL twice and the Voice Handicap Index (VHI) and Short Form Health Survey (SF-36) questionnaires once. Voice recordings were used for objective and perceptual assessment., Results: The I-SECEL demonstrated good test-retest reliability and internal consistency for 2 of 3 subscales. Correlations were moderate to strong between most of the I-SECEL scales and the VHI/SF-36 scales. The I-SECEL scales demonstrated moderate associations with most perceptual and objective measures., Conclusion: Preliminary evidence supports the convergent validity, test-retest reliability, and internal consistency of the I-SECEL, notwithstanding low internal consistency and test-retest reliability for 1 subscale., (Copyright © 2012 Wiley Periodicals, Inc.)

Multiple chemical sensitivity (MCS) is a relatively common clinical diagnosis in western populations and its symptoms (i.e. dysosmia) are mainly triggered by chemical compounds, such as common odorants. The aim of this study was to test the effect of intranasal administration of hyaluronic acid (HA) on odour threshold and related quality of life in MCS syndrome. Two randomized groups of MCS patients received 30 days’ administration of either a nasal spray (Ialumar®) containing HA [HA group (HAG); n=29] or only physiological solution[PS group (PG); n=30]. Both groups were investigated using the Sniffin’ Sticks test (SST) battery, Questionnaire of Olfactory Disorder (QOD) and Zung Anxiety Scale (SAS) before randomization and after treatment. Paired t-test analysis found a statistically significant reduction in odour threshold (OT) and an improvement in QOD and SAS between pre- and post-treatment results only in the HAG. Furthermore, positive correlations were found between the OT reduction, SAS and QOD improvement. Thus, intranasal administration of HA could be suggested as a further well-tolerated resource in alleviating MCS olfactory discomfort.

Objective: To evaluate through a multidimensional protocol voice changes after voice therapy in patients with benign vocal fold lesions., Methods: 65 consecutive patients affected by benign vocal fold lesions were enrolled. Depending on videolaryngostroboscopy the patients were divided into 3 groups: 23 patients with Reinke's oedema, 22 patients with vocal fold cysts and 20 patients with gelatinous polyp. Each subject received 10 voice therapy sessions and was evaluated, before and after voice therapy, through a multidimensional protocol including videolaryngostroboscopy, perception, acoustics, aerodynamics and self-rating by the patient. Data were compared using Wilcoxon signed-rank test. Kruskal-Wallis test was used to analyse the mean variation difference between the three groups of patients. Mann-Whitney test was used for post hoc analysis., Results: Only in 11 cases videolaryngostroboscopy revealed an improvement of the initial pathology. However a significant improvement was observed in perceptual, acoustic and self-assessment ratings in the 3 groups of patients. In particular the parameters of G, R and A of the GIRBAS scale, and the noise to harmonic ratio, Jitter and shimmer scores improved after rehabilitation. A significant improvement of all the parameters of Voice Handicap Index after rehabilitation treatment was found. No significant difference among the three groups of patients was visible, except for self-assessment ratings., Conclusion: Voice therapy may provide a significant improvement in perceptual, acoustic and self-assessed voice quality in patients with benign glottal lesions. Utilization of voice therapy may allow some patients to avoid surgical intervention., (Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.)

The objective of this study was to evaluate the reliability of the INFVo scale and its relationship with objective measures and VHI scores in 40 native Italian-speaking patients with substitution voice. The maximum phonation time (MPT), diadochokinesis (DDK) of the three syllabic sequence [pa/ta/ka], reading of a passage and a single word repetition test were recorded. Each patient completed the Italian version of the VHI. Three speech-language pathologists blindly rated the recordings using the auditory perceptual INFVo scale; one listened and assessed the voice recording twice. The INFVo intra- and inter-rater reliability reached good values. Strong to moderate correlations between the INFVo scale scores and MPT, DDK, distortions in the repetition test, speech rate during reading and the functional subscale of the VHI were found. In conclusion, the INFVo scale is a reliable tool and can be recommended for the perceptual assessment of substitution voices in Italian speaking patients.

Granulocytic sarcoma (GS) is a rare extramedullary solid tumor defined as an accumulation of myeloblasts or immature myeloid cells. It can cooccur with or precede the acute myeloid leukemia (AML) as well as following treated AML. The incidence of GS in AML patients is 3-8% but it significantly rises in M2 FAB subtype AML. This variety of AML harbors t(8;21) in up to 20-25% of cases (especially in children and black ones of African origin) and, at a molecular level, it is characterized by the generation of a fusion gene known as RUNX1-RUNX1T1. Approximately 10% of M2 AML patients will develop GS, as a consequence, the t(8;21) and the relative transcript represent the most common cytogenetic and molecular abnormalities in GS. FLT3-ITD mutation was rarely described in AML patients presenting with GS. FLT3 ITD is generally strongly associated with poor prognosis in AML, and is rarely reported in patients with t(8;21). GS presentation is extremely variable depending on organs involved; in general, cranial bones and sinus are very rarely affected sites. We report a rare case of GS occurring as a recurrence of a previously treated t(8;21), FLT3-ITD positive AML, involving mastoid bones and paravertebral tissues.

Benign vocal fold lesions are common in the general population, and have important public health implications and impact on patient quality of life. Nowadays, phonomicrosurgery is the most common treatment of these lesions. Voice therapy is generally associated in order to minimize detrimental vocal behaviours that increase the stress at the mid-membranous vocal folds. Nonetheless, the most appropriate standard of care for treating benign vocal fold lesion has not been established. The aim of this study was to analyze voice changes in a group of dysphonic patients affected by benign vocal fold lesions, evaluated with a multidimensional protocol before and after voice therapy. Sixteen consecutive patients, 12 females and 4 males, with a mean age of 49.7 years were enrolled. Each subject had 10 voice therapy sessions with an experienced speech/language pathologist for a period of 1-2 months, and was evaluated before and at the end of voice therapy with a multidimensional protocol that included self-assessment measures and videostroboscopic, perceptual, aerodynamic and acoustic ratings. Videostroboscopic examination did not reveal resolution of the initial pathology in any case. No improvement was observed in aerodynamic and perceptual ratings. A clear and significant improvement was visible on Wilcoxon signed-rank test for the mean values of Jitt%, Noise to Harmonic Ratio (NHR) and Voice Handicap Index (VHI) scores. Even if it is possible that, for benign vocal fold lesions, only a minor improvement of voice quality can be achieved after voice therapy, rehabilitation treatment still seems useful as demonstrated by improvement in self-assessment measures. If voice therapy is provided as an initial treatment to the patients with benign vocal fold lesions, this may lead to an improvement in the perceived voice quality, making surgical intervention unnecessary. This is one of the first reports on the efficacy of voice therapy in the management of benign vocal fold lesions; further studies are needed to confirm these preliminary data.

Background: Xerostomia is a common adverse event of unknown etiology observed during pegylated interferon (PegIFN)/Ribavirin (Rbv) treatment., Objectives: To assess the frequency and mechanisms of xerostomia during PegIFN/Rbv therapy., Patients and Methods: Thirty-one naïve patients with chronic hepatitis C consecutively received PegIFN-α2a (180 μg/week) plus Rbv (800-1200 mg/day). The controls were 10 patients with chronic hepatitis B who received PegIFN-α2a (180 μg/week). During treatment and follow-up, all patients underwent basal and masticatory stimulated sialometry,otorhinolaryngoiatric (ORL) examination, and a questionnaire survey to subjectively assess symptoms of oral dryness., Results: Twenty-seven patients on PegIFN/Rbv and 4 on PegIFN (87% vs. 40%, P = 0.006) reported xerostomia. Thirty patients on PegIFN/Rbv combination therapy and 2 patients on monotherapy had ORL signs of salivary gland hypofunction (97% vs. 20%, P < 0.0001).Mean basal (A) and stimulated (B) salivary flow rates (mL/min) progressively decreased during PegIFN/Rbv treatment (A, 0.49 at baseline vs. 0.17 at the end of treatment, P < 0.0001; B, 1.24 at baseline vs. 0.53 at the end of treatment, P = 0.0004). At week 24 following PegIFN/Rbv treatment, salivary flow rates were similar to baseline (A, 0.53 at the end of follow-up vs. 0.49 at baseline; B, 1.19 at the end of follow-up vs. 1.24 at baseline). Salivary function was unaffected in monotherapy patients., Conclusions: Rbv causes salivary gland hypofunction in hepatitis C patients receiving PegIFN/Rbv therapy, which promptly reverts to normal upon cessation of treatment.

Options for the surgical closure of large symptomatic perforations are limited and consist of an open or closed approach using skin or mucosal flaps, with or without different grafts. The aim of this study is to review our experience in treating large nasal perforations using a closed approach with endoscopic assistance, undertaking a 3-layer reconstruction of the septum. We reviewed 14 consecutive patients with large (2-4 cm) nasal septal perforations, who were treated using an endonasal/endoscope-assisted approach. In these cases, the mucosal defect was reconstructed through a horizontal advancement of the bipedicled mucoperichondrial flaps and sutured using absorbable sutures. The cartilagineous defect was consistently reconstructed using autogenous auricular conchal grafts. Pre- and postoperative nasal symptom scores were used for the study; a decline in the number of Nasal Obstruction Symptom Evaluation Scale symptoms were recorded in 12 of 14 patients (85.7%), and visual analogue scale scores for crusting, bleeding, nasal discharge, whistling, headache, nasal pain, snoring, olfactory loss, and overall discomfort levels also decreased. It was concluded that bipedicled mucoperichondrial flaps with the insertion of auricular cartilage for a 3-layer septal reconstruction seem to give reasonably good results. The use of nasal endoscopy is an endonasal approach, which offers superior precision in all surgical steps and provides a way to obtain excellent closure of the perforation without external incisions.

Trans-oesophageal echocardiography is generally considered a safe procedure, but occasional life-threatening complications have been reported. The aim of this clinical investigation is to outline the need of surgical management in cases of large retro-pharyngeal haematoma following trans-oesophageal echocardiography. In the case reported here, a patient with cervical spondylosis on anti-coagulant therapy was referred to the Head and Neck Department because of a retro-pharyngeal haematoma with severe upper airway obstruction following transoesophageal echocardiography. Tracheotomy was required to guarantee respiratory function, while trans-cervical surgery was performed to evacuate the haematoma. Total recovery was achieved within 10 days. In conclusion, the head and neck surgeon should consider the need of surgical management in cases of retro-pharyngeal haematoma following trans-oesophageal echocardiography.

Objective: To evaluate the internal consistency, reliability and clinical validity of the Italian version of the Pediatric Voice Handicap Index (pVHI)., Patients and Methods: The parents of 30 children with dysphonia and 43 asymptomatic children were included in the study. Each parent was asked to complete the Italian pVHI autonomously. The voice of each child was assessed perceptually through the GRB parameters of the GRBAS scale. Internal consistency was analyzed through Cronbach's α coefficient. For test-retest reliability analysis, the Italian pVHI was filled twice, with a 2-week interval, and the scores obtained were compared through the Pearson correlation test. Clinical validity was assessed comparing the scores obtained in the pathological and the control group using the Mann-Whitney test. Finally, the correlation between pVHI and the perceptual parameters was assessed., Results: All of the parents filled in the entire questionnaire autonomously. An optimal internal consistency was found (α = 0.95); the test-retest reliability in the parents of both groups of children was high (r > 0.88). The control group scored significantly lower than the pathological group (p = 0.0001). The pVHI scores positively correlated with perceptual assessment of voice disorders., Conclusion: The Italian pVHI is easily administered, highly reproducible, and exhibits excellent clinical validity., (Copyright © 2010 S.

Objectives: To evaluate the internal consistency, reliability, and clinical validity of the Italian version of the Voice Handicap Index (VHI)., Study Design: Cross-sectional survey study was carried out., Methods: One hundred and seventy-five patients with voice disorders, divided in four groups according to the etiology of the disease (neurogenic, structural, functional, and inflammatory), and 84 asymptomatic subjects were included in the study. Internal consistency was analyzed through Cronbach α coefficient. For the VHI test-retest reliability analysis, the Italian VHI was filled twice by 56 patients and 56 control subjects. The test-retest reliability was assessed through the Pearson correlation test. For the clinical validity assessment, the scores obtained in the pathological group were compared with those found in asymptomatic individuals through the Kruskal-Wallis test. Also, the correlation between VHI and the grade of voice disorder was assessed. Finally, the effect of age and gender on overall VHI and its three subscales was analyzed., Results: Optimal internal consistency was found (α=0.93); the test-retest reliability in both groups was high (r>0.86). Nonparametric Kruskal-Wallis analysis of variance for the overall VHI score and its three domains revealed a significant main effect for group (P=0.000). The control group scored significantly lower than the four groups of voice-disordered patients. The overall VHI score positively correlated with the grade of voice disorder (r=0.43). In the voice-disorder group, age and gender were not correlated to the overall VHI score and to their three domains., Conclusion: The Italian VHI is highly reproducible, and exhibits excellent clinical validity., (Copyright © 2010 The Voice Foundation.

Merkel cell carcinomas are uncommon malignant tumors thought to originate from the neuroendocrine cells of the skin that mainly affects sun-exposed body areas, particularly the head and neck. In approximately 10% of cases, they present with localized lymphadenopathy without any clinical evidence or history of a primary lesion, but a truly primary lymph node Merkel cell carcinoma may occur, possibly originating from epithelial inclusions or an anomalous neuroendocrine differentiation of hematopoietic stem cells. It has been observed that Merkel cell carcinoma is more likely to affect patients whose immune status is impaired as a result of iatrogenic immunosuppression, human immunodeficiency virus infection, or hematological malignancies. This study reports the case of a bona fide primary Merkel cell carcinoma arising in an intraparotid lymph node of a patient infected by HIV that had a particularly unfavorable clinical course.

In this prospective study, we have proposed a new method to straighten the caudal septum using a modified spreader graft interlocked on the convex side. A single-interlocked graft inserted by 2 through-and-through serial sections of the quadrangular cartilage (applied over the misshapen convex side previously scored on the concave side) facilitated adjustment of the distal septum intraoperatively. The strip of cartilage of the desired height and width acted as a spring graft and may be placed at the desired height of the caudal septal area to exactly counteract the eventual tendency of the most deviated area to warp over time. All 15 patients treated had improvement of their nasal airway and in their postoperative appearance of the external and internal nose. Our technique is easy to perform and shows long-term reliability in correcting caudal septal deviation, demanding a wider application to confirm its effectiveness on a larger series of patients.

PANDAS (pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections) is a rare clinical syndrome characterized by the presence of tics, Tourette syndrome, obsessive-compulsive disorder, or chorea in the context of an immediately precedent streptococcal infection. In this report, we describe the case of an 11-year-old boy who developed PANDAS with severe choreic movements. The criteria for PANDAS diagnosis were met. Moreover, serum antibrain antibodies were present. The patient was initially treated with tetrabenazine 12.5 mg twice daily with remission of the neurological symptoms. Subsequently, the patient underwent tonsillectomy and has been asymptomatic since, with antistreptolysin O titer levels in range.

Objectives: We describe the role of the laryngeal adductor reflex (LAR) and fiberoptic endoscopic evaluation of swallowing with sensory testing (FEESST) in the rehabilitation of patients with oropharyngeal dysphagia after partial laryngectomy., Methods: Ten patients with a mean age of 64 years (range, 45 to 72 years) were included in the study. Seven patients underwent supraglottic laryngectomy, and 3 had supracricoid laryngectomy. Six patients underwent additional radiotherapy (RT), and 8 had functional neck dissection (ND). FEESST was performed on each patient in order to establish a swallowing rehabilitation program., Results: In 2 patients, not submitted to either ND or RT, the LAR was preserved; in 6 patients, who underwent both procedures, the LAR was delayed or absent. In 2 patients who underwent ND but not RT, the LAR was preserved in 1 case and delayed in the other. The patients with an absent LAR presented severe aspiration, whereas in those with a preserved LAR, no penetration was found. Moderate aspiration was found in the remaining patients. In the patients with a reduced or absent LAR, tactile and chemical sensory stimulation was added to the rehabilitation program., Conclusions: FEESST represents a useful tool in everyday clinical practice for the planning of swallowing rehabilitation after partial laryngectomy.

Objectives: To evaluate the correlation between the Voice Handicap Index (VHI) and objective voice measurements in patients with dysphonia of different origin., Study Design: Cross-sectional survey., Setting: Otolaryngology department in a university hospital., Subjects and Methods: One hundred fifteen patients consulting for voice disorders were enrolled in the study: 32 presented with functional dysphonia (Group 1), 24 with unilateral vocal fold paralysis (Group 2), 30 with structural dysphonia (Group 3), and 29 with nodules (Group 4). From each patient, the maximum phonation time (MPT) and a voice spectrogram were obtained: patients with type 1 signal underwent perturbation analysis. Each patient completed the VHI., Results: No significant difference across the four groups, in the VHI scores and voice measurements, was found. The correlation between the different voice measurements was good, while those between the VHI domains were very good. Considering the patients with type 1 signal (n = 80) all together, the correlations between VHI and voice laboratory measurements ranged between poor and good. Analyzing each patient group separately, good correlations were found between MPT and functional and physical VHI domain in Group 1 (r = 0.58 and 0.68), jitter and functional VHI domain in Group 2 (r = 0.61), MPT and functional VHI domain in Group 3 (r = 0.52), and physical VHI domain and jitter, shimmer, and noise-to-harmonic ratio in Group 4 (r = 0.58, 0.77, 0.76)., Conclusion: The VHI and the voice laboratory measurements give independent information. However, the correlation between VHI and some laboratory measurements increases in populations with voice disorder of the same origin.

The aim of this study was to report some clinical cases suggesting a possible correlation between benign paroxysmal positional vertigo (BPPV) and intense physical activity. Out of 430 BPPV cases referred to our out-patients clinic, 9 patients, showing symptoms of BPPV arising after an intense period of physical activity, were selected for this study. The posterior semicircular canal was affected in all the nine patients. The canalith repositioning procedure was successful and eliminated vertigo and nystagmus in all patients. During the follow-up period (12 months) all patients continued with the usual physical activity; four of the nine patients showed a recurrence of the BPPV symptoms after a new intense period of exercises: all were successfully treated by a new single Epley repositioning procedure. BPPV due to intense physical activity is a rare condition (9/430) and it may be caused by repeated vibratory vertical accelerations of a minor degree associated with metabolic variations during strenuous exercise.

The aim of this study was to analyze the effect of acute vestibular deficit on the cerebral cortex and its correlation with clinical signs and symptoms. Eight right-handed patients affected by vestibular neuritis, a purely peripheral vestibular lesion, underwent two brain single photon emission computed tomography (SPECT) in 1 month. The first SPECT analysis revealed reduced blood flow in the temporal frontal area of the right hemisphere in seven of eight patients, independent of the right/left location of the lesion. The alteration was present always in the right, non-dominant hemisphere and was reversible in some patients 1 month after the onset, together with attenuation of signs and symptoms. It may be hypothesized that the transient reduction of cortical blood flow and subsequently of cortical activity in the non-dominant hemisphere, also the expression of cerebral plasticity, may serve as a defense mechanism aimed to attenuate the vertigo symptom.

Objectives: Flexible fiberoptic endoscopes have made pediatric laryngeal examinations an everyday practice, even though fiberoptic-flexible laryngoscopy (FFL) is not always well tolerated in young children because of limited cooperation. Laryngeal ultrasonography (LUS) has been applied to normal and pathological findings in infants and children, allowing the assessment of subglottic hemangiomas, laryngeal stenosis and paralysis. No previous study assessed benign vocal folds lesions by LUS in children. The aim of this study is to evaluate the possibility of LUS to detect benign vocal fold lesions in children by comparing the results of FFL in 16 children with those of LUS., Methods: Sixteen children (9 males and 7 females) with a mean age of 7.5+/-4.0 years were included in the study. Each child underwent FFL performed by a skilled phoniatrician and LUS performed blindly by an expert radiologist., Results: On FFL bilateral vocal folds nodules were found in 9 patients, vocal fold cyst in 2 other patients, while in 2 children the vocal folds appeared normal. Laryngeal papyllomatosis, vocal fold polyp and vocal fold irregularity were found in only one patient. LUS enabled the diagnosis in all the 14 patients with vocal fold lesions. Bilateral hyperechoic lesions were visible in 10 patients, while hypoechoic lesions were found in three patients. No lesion were found in two children, while one patient presented with a monolateral hyperechoic lesion., Conclusions: LUS was accurate, safe, well accepted and tolerated. LUS appears to be a useful diagnostic tool for supplementing FFL in the assessment of benign vocal fold lesions in children and may represent an interesting alternative in everyday clinical practice.

Intranasal schneiderian exophytic squamous papillomatosis is rare and often secondary to human papilloma virus infection. Treatment usually consists of repeated surgical or endoscopic excisions due to recurrences. The use of intravenous or intralesional or topically applied cidofovir, a cytidine nucleotide analogue suppressing viral replication, alone or as adjuvant therapy has been proposed and described in the literature for the treatment of other human papillomavirus (HPV)-related lesions. We firstly describe a successful combined approach of surgery and topical cidofovir for recurrent nasal HPV-related exophytic squamous papillomatosis in a HIV-infected patient. As no untoward effects were encountered this therapeutical option should be considered in the management of recurrent nasal papillomatosis in HIV-infected patients.

Objectives/hypothesis: : Supracricoid laryngectomies (SCL) are conservative surgical techniques for the treatment of selected laryngeal carcinomas, currently adopted also in old patients. Long-term functional results have not been reported in elderly patients. The aim of this study is to compare voice and swallowing in elderly and younger patients following SCL., Study Design: : Cross-sectional study., Methods: : Twenty male patients who underwent SCL were recruited in the study; 10 were younger than 65 years at the time of surgery and 10 were older. Video-endoscopic ratings were taken of neoglottic vibration patterns and bolus transit. Voices were perceptually rated using the GIRBAS scale. The maximum phonation time (MPT) and the syllables diadochokinesis were measured. Spectrograms were recorded. All of the patients completed a self-assessment questionnaire for both voice and swallowing. The data obtained from the two groups were compared through the Mann-Whitney test., Results: : Video-endoscopic ratings of neoglottal vibration and bolus transit showed no difference between the two groups. The perceptual assessment showed a harsh voice in both groups. No significant difference was found for mean syllable diadochokinesis and the mean MPT was 6.3 seconds and 8.8 seconds, respectively in the younger and older group. The mean value of the Yanagihara scale of voice spectrogram was 3.8 and 3.7. Voice and swallowing quality-of-life questionnaires revealed satisfied patients in both age groups., Conclusions: : Age by itself does not have a significant impact on long-term functional results following SCL. Meticulous selection of the candidate to SCL allows the application of this surgical technique with adequate long-term functional results. Laryngoscope, 2009.

Objectives: Impaired cochlear perfusion seems to be an important event in sudden sensorineural hearing loss. Prothrombotic gene mutations have been related to vascular disorders and sudden hearing loss. We assessed the prothrombotic risk in 10 patients with sudden sensorineural hearing loss who had previously experienced cardiovascular events to support its vascular pathogenesis., Methods: Ten patients underwent hematologic tests (MTHFR C677T/A1298C, prothrombin G20210A, platelet GlyIIIaA1/A2, and V Leiden G1691A genotyping; fibrinogenemia; cholesterolemia: homocysteinemia; folatemia). The results were compared with those of 100 previously investigated patients with sudden hearing loss alone and those of 200 healthy controls. DNA was isolated from peripheral blood leukocytes, and the gene mutations were investigated by polymerase chain reaction and a LightCycler DNA analyzer., Results: Two patients had 2 mutant alleles, 6 had 3, and 2 had 4. The mean homocysteine, cholesterol, and fibrinogen levels were above the upper limit of normal; the mean folate levels were slightly above the lower limit of normal. Multiple mutations were more frequent in the patient group than in the previously analyzed patients and healthy controls., Conclusions: The association between inherited and acquired prothrombotic factors in patients with sudden sensorineural hearing loss and thrombotic diseases in other sites suggests that a multifactorial mechanism may underlie microvascular cochlear impairment. Hematologic investigation, including MTHFR, prothrombin, platelet, and V Leiden genotyping, may help to detect patients at potential risk of recurrent hearing loss and multiple microvascular diseases, and could be usefully performed in otherwise idiopathic sudden sensorineural hearing loss.

Previous studies have investigated the relationship between muscular tension, body posture, and voice quality. The aim of this paper is to study the postural pattern during voice production in healthy subjects compared with patients affected by voice disorders and in the same patients before and after vocal treatment by means of static posturography. Classic posturographic variables and spectral frequency analysis of body sway have been measured. Posturographic values in patients before vocal treatment and controls were within normal ranges but not homogeneous. Body sway significantly decreased during voice production in patients after voice training. Spectral frequency analysis of body sway showed a significantly decreased body sway at middle frequencies on the anteroposterior (y) plane during voice production after voice training. Our results would suggest that in patients affected by voice disorders rehabilitative treatment may cause an improvement of the body proprioceptive scheme and this improvement might be useful to evaluate the proper (ongoing) treatment.

Objectives: Salivary duct disorders are the second most common cause of obstruction after calculi. Magnetic resonance sialography has been recently proposed as a means of diagnosing a heterogeneous group of salivary disorders, and so we compared it with sialoendoscopy in evaluating stenoses and sialectasia in 24 patients with obstructive symptoms and ultrasonographic results negative for calculi or masses., Methods: All of the patients (19 of whom had recurrent unilateral or bilateral swollen parotid glands and 5 of whom also had recurrent swollen submandibular glands) underwent dynamic color Doppler ultrasonography and dynamic magnetic resonance sialography with lemon juice stimulation of saliva; 18 patients also underwent diagnostic sialoendoscopy., Results: Ultrasonography and color Doppler ultrasonography showed duct dilatation in all patients (bilateral in 5 with parotid stenosis). Magnetic resonance sialography confirmed duct dilatation and stenosis in all of the patients, and revealed the simultaneous presence of calculi in 4 cases. A parotid sialocele was found in 4 cases. The magnetic resonance sialographic findings were confirmed in the patients who underwent sialoendoscopy. No side effects were observed., Conclusions: Magnetic resonance sialography following prediagnostic ultrasonography allows an adequate diagnosis of salivary duct disorders such as stenosis and sialectasia, as confirmed by objective sialoendoscopic assessment. Magnetic resonance sialography also makes it possible to visualize the salivary duct system up to its tertiary branches and, in this regard, may be considered a valid, noninvasive method for the evaluation of salivary duct disorders.

Unilateral vocal fold paralysis (UVFP) is associated with changes in acoustic and aerodynamic voice measurements and can have a significant impact on a patient's quality of life. Few objective data regarding the efficacy of voice therapy for UVFP exist. The aim of this study was to retrospectively analyze voice modifications in a group of patients with UVFP before and after voice therapy. Forty patients with UVFP of different etiology were included in the study. Each subject had voice therapy with an experienced speech/language pathologist twice a week; the mean number of sessions was 12.6. A multidimensional assessment protocol was used; it included videoendoscopy, the maximum phonation time (MPT), the GIRBAS scale, spectrograms and a perturbation analysis, and the Voice Handicap Index (VHI). Pre- and posttreatment data were compared by means of the Wilcoxon and Student's t tests. A complete glottal closure was seen in 8 patients before voice therapy and in 14 afterward. Mean MPT increased significantly. In the perceptual assessment, the difference was significant for five out of six parameters. A significant improvement was found on spectrographic analysis; as for perturbation analysis, the differences in jitter, shimmer, and noise-to-harmonic ratio values were significant. VHI values showed a clear and significant improvement. A significant improvement of voice quality and quality of life after voice therapy is an often reached and reasonable goal in patients with UVFP.

Introduction: Oropharyngeal dysphagia is a common symptom in patients with head and neck tumours. The MD Anderson Dysphagia Inventory (MDADI) is a questionnaire currently used in North America for the assessment of dysphagia-related disability in patients with head and neck cancer. The aim of the study is to analyze reliability and clinical validity of the Italian MDADI., Material and Method: 48 persons with no history of dysphagia and 50 head and neck cancer patients with a chronic and stable dysphagia have been included in the study. Each subject completed alone the Italian MDADI twice with a week interval between the two questionnaire completion. Intra-subject reliability was analyzed through Pearson test in both groups of subjects. Clinical validity was calculated through the non parametric Mann Whitney test of the first MDADI assessment in both groups., Results: Internal consistency and test-retest reliability were high for each MDADI subscale in subjects without dysphagia as well as in those with dysphagia. The difference between MDADI values in subjects with and without dysphagia was significant for each subscale., Discussion: The Italian MDADI is reliable and clinically valid. The application of the MDADI is recommended in clinical practice as well as in descriptive, outcome and efficacy research.
