Patients with age-related sensorineural hearing loss (HL) may benefit from auditory input amplification by using hearing aids (HA). However, the impact of both HL and HA-based rehabilitation on central auditory functional connectivity (FC) is not clear.

Background Since the spreading of SARS-CoV-2 from China, all deferrable medical activities have been suspended, to redirect resources for the management of COVID patients. The goal of this retrospective study was to investigate the impact of COVID-19 on head and neck cancers’ diagnosis in our Academic Hospital. Methods A retrospective analysis of patients treated for head and neck cancers between March 12 and November 1, 2020 was carried out, and we compared these data with the diagnoses of the same periods of the 5 previous years. Results 47 patients were included in this study. We observed a significative reduction in comparison with the same period of the previous 5 years. Conclusions Our findings suggest that the COVID-19 pandemic is associated with a decrease in the number of new H&N cancers diagnoses, and a substantial diagnostic delay can be attributable to COVID-19 control measures.

To systematically review outcomes of orbital bony wall decompression for Grave’s orbitopathy according to the surgical approach. A systematic search for studies published in “Ovid MEDLINE”, “Web of Science” and “Embase” of patients with surgical treatment of Grave’s orbitopathy was performed. The overall postoperative change in Hertel exophthalmometry was calculated by random-effect meta-analysis model with 95% confidence interval (CI). A total of 33 studies, including 1686 patients and 2946 procedures, were included. The weighted mean Hertel value overall reduction was − 4.56 mm (95% CI − 5.05 to − 4.07 mm). According to surgical techniques the reduction was − 4.36 mm (95% CI − 5.22 to − 3.50) for infero-medial technique, − 4.88 mm (− 5.68 to − 4.08) for medial–lateral technique, − 4.32 mm (− 4.80to − 3.84) for lateral technique, − 5.45 mm (− 6.16 to − 4.74) for three-wall technique and − 3.47 mm (− 5.81 to − 1.12) for medial technique. The overall rate of new-onset of primary gaze diplopia was reported in 23 studies. The included procedures were 653 and results were heterogeneous (heterogeneity: Q = 78.8 df = 22, I2 = 72.09%, p

Tapia syndrome is a rare complication after surgery, with ipsilateral paralysis of vocal cord and tongue due to extracranial involvement of recurrent laryngeal and hypoglossal nerves. Tapia’s case report is extremely interesting for both the rarity of the reported cases and for the importance of an early rehabilitation. In a previous work, we reported a case of Tapia syndrome after cardiac surgery for aortic aneurysm, and the protocol of logopedic rehabilitation adopted. In the postoperative period, he developed severe dyspnea and dysphagia that required a tracheostomy and a logopedic rehabilitation therapy that led to a fast and efficient swallowing without aspiration after 47 sessions (less than 4 months). The progressive recovery of the function suggests aprassic nerve damage. However, the logopedic therapy is recommended to limit the possibility of permanent functional deficits and quickly recover swallowing and phonation.

Meniere's Disease (MD) is an inner ear disorder characterized by spontaneous recurrent vertigo, fluctuating sensorineural hearing loss, aural fullness and low-pitch tinnitus. Therapeutic management of MD includes dietary restriction and medical therapy. A minority of cases is characterized by frequent vertigo attacks, progressive hearing loss and persistent tinnitus even through the continuous medical treatments; this condition is called intractable MD and requires a therapeutic escalation from non-invasive medical treatment to surgical intervention. Invasive procedures include endolymphatic sac surgery, vestibular nerve section and labyrinthectomy. These procedures have a very high success rate on symptom control but may have a severe impact on the hearing function. However, the simultaneous combined approach of demolitive surgery and cochlear implantation may be a valid approach to treat symptoms of intractable MD and preserve hearing function. In the present study, we review current literature focusing on intractable MD to describe and discuss advantages and disadvantages of established and newly proposed surgical treatments for intractable MD.

Background: The treatments of horizontal semicircular canal benign paroxysmal positional vertigo (HSC-BPPV) have low remission rates ranging between 60% and 90%, connected to the difficulty in corr...

Age-related sensorineural hearing loss (HL) leads to localized brain changes in the primary auditory cortex, long-range functional alterations, and is considered a risk factor for dementia. Non-human studies have repeatedly highlighted cross-modal brain plasticity in sensorial brain networks other than those primarily involved in the peripheral damage, thus in this study, the possible cortical alterations associated with HL have been analyzed using a whole-brain multimodal connectomic approach. Fifty-two HL and 30 normal hearing participants were examined in a 3T MRI study along with audiological and neurological assessments. Between-regions functional connectivity and whole-brain probabilistic tractography were calculated in a connectome-based manner and graph theory was used to obtain low-dimensional features for the analysis of brain connectivity at global and local levels. The HL condition was associated with a different functional organization of the visual subnetwork as revealed by a significant increase in global efficiency, density, and clustering coefficient. These functional effects were mirrored by similar (but more subtle) structural effects suggesting that a functional repurposing of visual cortical centers occurs to compensate for age-related loss of hearing abilities.

Objective To assess efficacy and safety of tonsil reduction with bipolar forceps electrocautery as treatment of paediatric obstructive sleep apnea/hypopnea syndrome (OSAHS). Study design Prospective interventional study. Methods Two hundred and sixty-three children aged 4–10 years with OSAHS and an apnea hypopnea index (AHI) > 3 were enrolled from March 2013 to January 2016. Pre-operative evaluation included oropharyngeal clinical examination with fiberoptic nasopharyngoscopy, OSA-18 questionnaire and overnight sleep study. All children were treated with adenoidectomy and tonsillotomy with bipolar forceps. OSA-18 questionnaire and overnight sleep study were performed 30 days after surgery. Results Pre-operative average of the OSA-18 questionnaires was of 70.3 (SD = 9.7); 30-day post-operative score was 23.15 (SD = 8.2; p = 0.045). Pre-operative average Apnea Hypopnea Index (AHI) score was 9.41 (SD = 4.1); 30-day post-operative average of AHI score was of 1.75 (SD = 0.8; p = 0.012). Oxygen Desaturation Index (ODI) rate changed from 7.39 (SD = 4) to 1.34 (30-day post-operative) (SD = 4.7; p = 0.085). NADIR rate changed from 79% (SD = 6.32) to 90% (30-day post-operative) (SD = 5.18; p = 0.00012). Peri- and post-operative complications in our sample were mainly pain (average 75 doses of paracetamol), while bleeding did not occur (0%). All patients received a follow-up examination 5 years after surgery to evaluate tonsil size; at this time-point, a reduction in tonsil size from 3.6 (3–4; SD = 4.2) to 1.3 (1–2; SD = 5.5) was found, while tonsil regrowth was observed in five children (2%). Conclusion This study showed that partial tonsillotomy with bipolar forceps electrocautery associated to adenoidectomy is an effective technique in treating OSAHS symptoms in children and ensures less complications in terms of hemorrhage, postoperative pain and infections compared to traditional adenotonsillectomy. The very low tonsillar regrowth rate reported in this study may support the routine use of this technique.

Laryngeal carcinoma is the second common malignancy of the upper aerodigestive tract after lung cancer; in most cases is a squamous cell carcinoma, whose risk factors include tobacco smoking and alcohol consumption. Despite therapeutic progress, the five-year overall survival rate for this malignancy has remained nearly 50% and many patients already present metastasis at the time of diagnosis. To date, there are no tools that predict the evolution of laryngeal carcinoma: in this light, during the last years, many studies were planned with the aim to investigate the role played by different biomarkers expressed by larynx cancer, which can help make an early diagnosis, predict disease evolution and direct therapeutic choice. This review aims to summarize these markers and correlating them with disease evolution.

Few studies have investigated the neuropsychological profile of Hearing Loss (HL) subjects and the effects of hearing-aid on cognitive decline. We investigated the neuropsychological profile of HL patients at baseline and compared the neuropsychological profiles of patients with and without hearing-aid at 6 month. Fifty-six HL patients and 40 healthy subjects (HC) underwent neuropsychological and behavioral examination and were compared at baseline. Changes at follow-up were compared between HL patients with (N = 25) and without (N = 31) hearing-aids. At baseline, significant differences between HL and HC were found in MOCA test, Raven's Coloured Progressive Matrices (CPM) and SF-36. Among mild-HL patients, patients with hearing-aid significantly improved on the Clock Drawing Test (CDT) as compared to patients without hearing-aid. Our findings indicate that hearing loss is associated with both a reduced efficiency of the global cognitive state and a worse quality of life as compared to HC, supporting the association between HL and cognitive impairment. Moreover, only patients with mild-HL shows some cognitive improvement after using hearing-aid, suggesting that rehabilitative strategies may be more effective to delay cognitive decline in such patients. However, we cannot exclude that hearing-aids may affect cognitive decline in more severe-HL, but a longer follow-up is needed.

Self-Contained Underwater Breathing Apparatus (SCUBA) diving is a popular sport. However, improper diving may injure different organs. The majority of dive-related disorders concern otolaryngology, and may include hearing loss, tinnitus, aural fullness, disequilibrium, and vertigo. Three main inner ear pathological conditions can occur underwater: inner ear barotrauma (IEB), inner ear decompression sickness (IEDS), and alternobaric vertigo (AV). IEB results from inappropriate equalization of middle ear pressure and consequent inner ear injury produced by pressure changes within the middle ear; IEDS is characterized by the formation of gas bubbles within the vessels of the inner ear during rapid ascent; AV typically develops while ascending or performing the Valsalva maneuver and can follow asymmetrical equalization of middle ear pressure transmitted via the oval and round window membranes. The clinical pictures of these pathological conditions are partly superimposable, even if they have specific peculiarities. Before starting SCUBA diving, a fit-to-dive assessment is recommended. It should include an otolaryngologic examination with audiological assessment to evaluate nasal, middle ear, and tubal patency and to minimize the risk of IEB, IEDS, and AV. It is of utmost importance to identify individual risk factors and predisposing pathological conditions that favor inner ear injury before diving, to prevent acute events and preserve auditory and vestibular functions in SCUBA divers. This review aims to provide an overview of the pathological conditions characterized by inner ear injury in SCUBA divers, discussing their pathogenetic mechanisms, diagnostic work-up, and prevention.

BACKGROUND: Presbycusis is the hearing loss (HL) determined by aging mechanisms affecting the inner ear. Auditory cortical hypoperfusion has been shown in the early phases of presbycusis, suggesting a regionally selective metabolic vulnerability secondary to peripheral loss of function. In this study, HL patients were stratified according to the audiogram profiles to possibly enable a finer regional characterization of cortical perfusion changes within the primary auditory cortex. METHODS: Sixty-two HL patients (age range: 47-78 years, PTA

The aim of this work is to clarify the incidence of meningitis/encephalitis in SARS-CoV-2 patients. We conducted an initial search in PubMed using the Medical Subject Headings (MeSH) terms "meningitis," and "encephalitis,", and "COVID-19" to affirm the need for a review on the topic of the relationship between meningitis/encephalitis and SARS-CoV-2 infection. We included case series, case reports and review articles of COVID-19 patients with these neurological symptoms. Through PubMed database we identified 110 records. After removal of duplicates, we screened 70 record, and 43 were excluded because they focused on different SARS-CoV-2 neurological complications. For eligibility, we assessed 27 full-text articles which met inclusion criteria. Seven articles were excluded, and twenty studies were included in the narrative review, in which encephalitis and/or meningitis case reports/case series were reported. Neurological manifestations of COVID-19 are not rare, especially meningoencephalitis; the hypoxic/metabolic changes produced by the inflammatory response against the virus cytokine storm can lead to encephalopathy, and the presence of comorbidities and other neurological diseases, such as Alzheimer's disease, predispose to these metabolic changes. Further study are needed to investigate the biological mechanisms of neurological complications of COVID-19.

Purpose To investigate literature about pharmacological, surgical, and diagnostic innovations for Meniere’s Disease (MD) Summary Meniere’s disease is an inner ear disorder characterized by the presence of endolymphatic hydrops in the inner ear and symptomatology of recurrent and debilitating vertigo attacks, tinnitus, aural fullness, and fluctuating sensorineural hearing loss. Although many therapeutic options for MD have been proposed during years, no consensus has been reached by the scientific community. In the last decade, many therapeutic options have been proposed, as intratympanic steroid, intratympanic gentamicin, and intravenous glycerol. Recently, the role of the antisecretory factor in the diet of MD patients have been investigated. Surgery is recommended for intractable MD; some authors proposed new approaches including transcanal endoscopic infracochlear vestibular neurectomy, new marsupiliazation technique in sac surgery, and tenotomy of the stapedius and tensor tympani muscles.

Purpose: The presence of many asymptomatic COVID-19 cases may increase the risks of disease dissemination, mainly for physicians. There are numerous reports on the frequent findings of sudden anosmia or hyposmia, before or at the same time of the typical COVID-19 symptoms onset. The aim of this study was to verify the association of olfactory impairment and COVID-19, providing a basis for subsequent research in the field of COVID-19 clinical heterogeneity. Methods: We developed a 15-item online questionnaire on “Sudden Olfactory Loss (SOL) and COVID-19” that was administered during March 2020 to Italian general practitioners registered to a social media group. Results: One hundred and eighty responses were received. SOL was identified as a significant sign of infection in COVID-19 patients, mainly aged between 30 and 40 years, even in the absence of other symptoms. SOL was present as an initial symptom in 46.7% of subjects, and in 16.7%, it was the only symptom. Among the COVID-19 confirmed cases, SOL occurred as the only symptom in 19.2% of patients. Conclusion: SOL could represent a possible early symptom in otherwise asymptomatic COVID-19 subjects. Subjects affected by SOL should be considered as potential COVID-19 cases. Level of evidence: 4.

Acinic cell carcinoma (ACCs) is uncommon malignant epithelial neoplasm of the salivary glands; the most common presentation is a well-defined painless solid mass. Diagnosis of ACCs is frequently complicated, due to its similarity with benign tumors. A review of the literature available on ACCs was carried out. Studies were sourced from PubMed with searching of relevant headings and sub-headings and cross-referencing. There are no clear characteristics of ACCs found on CT, MRI and ultrasound imaging. The management of the ACC, a rare malignancy of the parotid gland, is often difficult and controversial. Radical surgery is the best treatment option. The role of radiotherapy remains controversial: the precise indications and oncologic effects of adjuvant radiotherapy in ACC of the parotid gland are not well known. There is insufficient literature regarding the chemotherapy for metastatic ACC. Knowledge about ACC, a rare malignancy of parotid gland, has changed over the past few decades. More clinical randomized works would be needed, both to assess the real effectiveness of radio and chemotherapy and to have an unanimous consensus about their indications.

Purpose: Specially processed cereals (SPC) that increase endogenous antisecretory factor (AF) synthesis have been proposed to improve symptoms of Meniere’s disease (MD) with controversial results. The aim of this study was to evaluate the effects of SPC in patients with definite unilateral MD and compare the results to a treatment protocol with intravenous glycerol and dexamethasone. Methods: Thirteen patients with unilateral MD were treated with SPC and 13 patients were treated with intravenous glycerol and dexamethasone for 12 months. Audio-vestibular evaluation was performed before (T0) and at the end of the treatments (T12). The number of vertigo spells were evaluated before and after therapy and the Efficacy Index (EI) was calculated. Questionnaires for hearing loss (HHIA), tinnitus (THI) and quality of life (TFL) were administered. Results: EI decreased in the SPC group in the second semester compared to the first although not significantly (p = 0.6323). There was a significant reduction for THI score in the SPC group at T12 (p = 0.0325). No significant differences were found between the two groups at T0 (p = 0.4723), while a significant difference was found at T12 (p = 0.0041). Quality of life showed an improvement in daily activities in the SPC group compared to infusion therapy group. Conclusion: Our study shows a reduced number of vertigo attacks and a positive effect on the discomfort generated by tinnitus and quality of life in patients with unilateral MD treated with SPC and when compared to patients treated with intravenous glycerol and dexamethasone. No effects on hearing thresholds were noted in both groups.

Air-bone gaps (ABGs) are commonly found in patients with conductive or mixed hearing loss generally due to outer- and/or middle-ear diseases such as otitis externa, tympanic membrane perforation, interruption or fixation of the ossicular chain, and chronic suppurative otitis media. ABGs can also be found in correlation with inner-ear disorders, such as endolymphatic hydrops, enlarged vestibular aqueduct syndrome, semicircular canal dehiscence, gusher syndrome, cochlear dehiscence, and Paget disease's as well cerebral vascular anomalies including dural arteriovenous fistula. The typical clinical presentation of inner-ear conditions or cerebral vascular anomalies causing ABGs includes audiological and vestibular symptoms like vertigo, oscillopsia, dizziness, imbalance, spinning sensation, pulsatile or continuous tinnitus, hyperacusis, autophony, auricular fullness, Tullio's phenomenon, and Hennebert's sign. Establishing a definitive diagnosis of the underlying condition in patients presenting with an ABG is often challenging to do and, in many patients, the condition may remain undefined. Results from an accurate clinical, audiological, and vestibular evaluation can be suggestive for the underlying condition; however, radiological assessment by computed tomography and/or magnetic resonance imaging is mandatory to confirm any diagnostic suspicion. In this review, we describe and discuss the most recent updates available regarding the clinical presentation and diagnostic workup of inner-ear conditions that may present together with ABGs.

Introduction Vertigo and disequilibrium are common symptoms in idiopathic Parkinson's disease (PD) and in Multiple System Atrophy (MSA). Hearing loss has been recently recognized as an additional non-motor feature in PD. The aim of this study is to evaluate audio-vestibular function in patients affected by PD and MSA. Methods Fifteen patients with PD, 16 patients with MSA and 20 age-matched healthy controls (HC) were enrolled. Audio-vestibular examination included pure-tone audiometry (PTA), vestibular bed-side examination, video Head Impulse Test (vHIT), and cervical Vestibular-Evoked Myogenic Potentials (cVEMPs). Results PD and MSA patients showed worse PTA thresholds compared to HC at high frequencies. MSA patients showed worse PTA thresholds at 125 Hz compared to HC. In patients with PD, a direct correlation between disease duration and PTA thresholds was found at 2000 Hz and 4000 Hz. In patients with MSA, disease duration was directly related to PTA thresholds at 125 Hz and 250 Hz. Among PD patients, cVEMPs were absent bilaterally in 46.7% and unilaterally in 13.3% of the subjects. Among MSA patients, cVEMPs were absent bilaterally in 26.7% and unilaterally in 40% of the subjects; p13 latency was significantly increased in PD patients as compared to HC. A significant inverse relationship was found between disease duration and cVEMP amplitude in MSA patients. Conclusion We found that high-frequency hearing loss and cVEMP abnormalities are frequent features of both MSA and PD, suggesting that an audio-vestibular dysfunction may be present in these patients even in the absence of self-reported auditory or vestibular symptoms.

Objective Temporal bone CSF leak represents a rare condition that may be associated to some particular symptoms as hearing loss, otorrhea and tinnitus. In the opinion of many authors a surgical treatment is mandatory to avoid serious consequences as meningitis. Middle cranial fossa (MCF), transmastoid (TM) and combined approaches are all described to manage this condition. The objective of this paper was firstly to analyze the overall outcomes of this surgery. Our second aim was to make a comparison between different surgical modalities on the basis of their rate of success and complications. Methods A search thorough Ovid MEDLINE was organized in January 2017 to enroll all eligible articles. A statistical analysis of the obtained data was performed. Results Thirtythree studies comprising a total of 873 procedures were included. The overall rate of success resulted 95.6% (94.1–96.8). The rate of major complications analyzed for 818 procedures was 3.4% (2.3–4.8). Subgroups analysis showed a success rate of 97.1% (90.7–99.5) for TM approach. A success rate of 94.1% (89.1–97.3) was calculated for MCF approach. Combined procedure (TM + MCF) showed a success rate of 97.9% (92.9–99.7). Conclusion The results of our review showed as the surgical treatment for CSF leak of temporal bone origin represents a safe option with high rate of success. Moreover our statistical data suggested that no significant differences are present in terms of outcomes between the analyzed surgical approaches.

Menezes et al. recently published an interesting study on cardiovascular prognostic factors for sudden sensorineural hearing loss (SSNHL), analyzing therapeutic strategies with intravenous and intratympanic corticosteroids and evaluating the application of the Systematic Coronary Risk Evaluation risk scale to classify risk in patients with SSNHL. In addition to intravenous and intratympanic corticosteroids, we would like to stress the role of hyperbaric oxygen therapy (HBOT). The new guidelines on SSNHL and the most recent scientific evidence emphasize the therapeutic role of HBOT. In a previous study, we recommended the use of HBOT in addition to intravenous steroid for patients with idiopathic SSNHL. For the best outcomes, we also recommended starting treatment within 14 days from the onset of SSNHL. In the same article, we discussed potential risk factors for SSNHL. Among cardiovascular risk factors, we suggest the possible association between patent foramen ovale (PFO) and SSNHL. The higher prevalence of PFO in our patients (50%) compared to controls suggests that SSNHL may be attributable to a paradoxical embolism, such as a venous embolism as a result of PFO.

Purpose There are many therapeutic options for Meniere's disease (MD); intratympanic (IT) gentamicin has been proposed for intractable cases although controversy about dosage and method exists. The purpose of this study was to assess the efficacy and safety of low-dose IT gentamicin on vertigo attacks in MD using a clinical symptomatology-based method in which administration was repeated only if vertigo attacks recurred, with a 2-week interval between injections. Materials and methods Forty-eight patients with unilateral intractable MD were included in the study. All patients received one to five IT injections with 0.5 ml of 10 mg of gentamicin (80 mg/2 ml) with an interval of 2 weeks between injections. Vertigo attacks were evaluated before and after therapy and categorized into classes A–F according to the 2015 Equilibrium Committee criteria. Audiovestibular assessment with pure tone audiometry, vestibular bed-side examination and video head impulse test was performed. Results Before treatment patients had an average of 4.4 vertigo attacks/month; after treatment the average number decreased to 0.52. The majority of patients (77%) reached Class A vertigo control with 5 or less gentamicin injections. VOR gain was unaffected in the healthy side and significantly reduced in the affected side. No hearing deterioration was found in all treated patients. Conclusions Low-dose IT gentamicin administration based on clinical symptomatology can produce a satisfactory control of vertigo attacks after treatment; such protocol had an effect mainly on the vestibular function as demonstrated by the significant reduction in VOR gain in the affected side avoiding a cochlear damage.

Background Chronic subjective dizziness (CSD) is characterized by persistent dizziness, unsteadiness, and hypersensitivity to one's own motion or exposure to complex visual stimuli. CSD may be triggered, in predisposed individuals with specific personality traits, by acute vestibular diseases. CSD is also thought to arise from failure to re-establish normal balance strategies after resolution of acute vestibular events which may be modulated by diathesis to develop anxiety and depression. Objective To confirm the role of personality traits linked to anxiety and depression (i.e., neuroticism, introversion, low openness) as predisposing factors for CSD and to evaluate how individual differences in these personality traits are associated with CSD severity. Methods We compared 19 CSD patients with 24 individuals who had suffered from periferal vestibular disorders (PVD) (i.e., Benign Paroxysmal Postural Vertigo or Vestibular Neuritis) but had not developed CSD as well as with 25 healthy controls (HC) in terms of personality traits, assessed via the NEO-PI-R questionnaire. Results CSD patients, relative to PVD patients and HCs, scored higher on the anxiety facet of neuroticism. Total neuroticism scores were also significantly associated with dizziness severity in CSD patients but not PVD patients. Conclusions Pre-existing anxiety-related personality traits may promote and sustain the initial etiophatogenetic mechanisms linked with the development of CSD. Targeting anxiety-related mechanisms in CSD may be therefore a promising way to reduce the disability associated with CSD.

Osmotic diuretics such as glycerol are used for diagnostic purposes in patients with a suspect of Meniere's disease (MD). Scientific evidence in the animal model and in humans has shown that glycerol can induce a reduction in endolymphatic hydrops; however, its use for therapeutic purposes in MD has never been reported. The aim of this study was to evaluate the effectiveness on symptom control of intravenous glycerol in a sample of patients with definite unilateral MD not responsive to dietary restrictions.Forty patients with unilateral intractable MD were included in the study. After audio-vestibular evaluation, patients were treated with intravenous 10% glycerol with 0.9% sodium chloride, 0.5 g/kg ml once a day for 2 consecutive days every fifteen days for six months. Vertigo attacks were evaluated before and after therapy and categorized into classes A-F according to the 2015 Equilibrium Committee criteria. Tinnitus and quality of life were evaluated through the Tinnitus Handicap Inventory and the Functionality Level Scale questionnaires.Before treatment, patients had an average of 3.2 vertigo attacks/month; during the six months after treatment the average number of attacks/month decreased to 1.2 (p 0.0001). At the end of the study period, 25 patients (62.5%) were in Class B vertigo control; 10 patients (25%) in Class C; and 5 patients (12.5%) in Class D. No patients were in Class A, E and F. No hearing deterioration was found in all treated patients. Quality of life according to administered questionnaires improved after treatment.In our sample, intravenous infusion of glycerol for two consecutive days every fifteen days for six months based on the patient's weight improved vertigo attacks and reduced the discomfort generated by tinnitus raising quality of life in patients with unilateral MD unresponsive to dietary restrictions.

Age-related hearing loss (HL) can be related to brain dysfunction or structural damage and may result in cerebral metabolic/perfusion abnormalities. Arterial spin labeling (ASL) magnetic resonance imaging (MRI) allows investigating noninvasively brain perfusion changes. Pseudocontinuous ASL and T1-weighted MRI (at 3 T) and neuropsychological testing (Montreal Cognitive Assessment) were performed in 31 HL (age range = 47–77 years, mean age ± SD = 63.4 ± 8.4 years, pure-tone average [PTA] HL > 50 dB) and 28 normal hearing (NH; age range = 48–78 years, mean age ± SD = 59.7 ± 7.4 years) subjects. Cerebral blood flow (CBF) and gray matter volume (GMV) were analyzed in the cortical volume to assess perfusion and structural group differences. Two HL subjects showing cognitive impairment were excluded from group comparisons. No significant differences in either global or local atrophy were detected between groups but the HL group exhibited significant regional effects of reduced perfusion within the bilateral primary auditory cortex, with maximal CBF difference (−17.2%) in the right lateral Heschl's gyrus. For the whole sample of HL and NH subjects (n = 59 = 31 HL + 28 NH), the regional CBF was correlated positively to the regional GMV (p = 0.020). In HL subjects (n = 31), the regional CBF was correlated negatively to the audiogram steepness (frequency range: 2–4 kHz, right ear: p = 0.022, left ear: p = 0.015). The observed cortical pattern of perfusion reduction suggests that neuronal metabolism can be related to HL before the recognition of brain structural damage. This also illustrates the potential of ASL-MRI to contribute early functional markers of reduced central processing associated with HL.

The aim of this study was to systematically review publications that investigated the prognostic role of E-cadherin immunostaining in patients affected by laryngeal squamous cell carcinoma. An appropriate string was run on PubMed to retrieve articles dealing with this topic. A double cross-check was performed on citations and full-text articles by two authors independently to analyse all manuscripts and perform a comprehensive quality assessment. Among 89 abstracts identified, 13 articles were included. These studies reported on 1,121 patients with histologically confirmed diagnosis of laryngeal squamous cell carcinoma. Overall, there were 10 studies that showed a significant correlation between E-cadherin immunohistochemical expression and at least one of the clinical and histopathological parameters considered by the authors. In particular E-cadherin expression was significantly associated with N stage (five studies), grading (four studies) and disease-free survival/disease-specific survival (six studies). In conclusion, the findings of our review appear similar to the results published by other authors on the putative role of E-cadherin in progression of malignancy. In fact, for laryngeal squamous cell carcinoma it seems that lower levels of E-cadherin correlate with increased tumoural aggressiveness and worse prognosis. Nevertheless, further high-quality prospective studies should be carried out to clarify if E-cadherin expression may be considered as an independent prognostic factor for patients affected by laryngeal cancer.Il significato prognostico dell’espressione di E-caderina nel carcinoma a cellule squamose della laringe: una revisione sistematica.L’obiettivo di questo studio è stato di revisionare in modo sistematico gli articoli che indagavano il ruolo prognostico dell’espressione immunoistochimica di E-caderina nei pazienti affetti da carcinoma laringeo a cellule squamose. Una stringa di parole chiave è stata utilizzata per trovare su PubMed gli articoli pubblicati riguardo a questo argomento. Una doppia scansione incrociata è stata poi eseguita da due degli autori sulle citazioni e sui testi degli articoli per analizzare tutti i lavori e ottenere una piena verifica della qualità di ricerca. Su un totale di 89 articoli identificati sono stati inclusi 13 studi. Questi studi riportavano 1.121 pazienti con diagnosi confermata di carcinoma laringeo a cellule squamose. Complessivamente 10 studi hanno mostrato una correlazione significativa tra l’espressione immunoistochimica di E-caderina con almeno uno dei parametri clinico-patologici presi in esame dagli autori. In particolare l’espressione di E-caderina è risultata statisticamente connessa allo stadio linfonodale (cinque studi), al grading istologico (quattro studi), alla sopravvivenza libera da malattia (sei studi). In conclusione i dati osservati nella nostra revisione appaiono simili ai risultati pubblicati da altri autori riguardo il possibile ruolo di E-caderina nella progressione di varie neoplasie maligne. Infatti anche per il carcinoma a cellule squamose della laringe sembra che livelli più bassi di E-caderina siano correlati ad un aumento dell’aggressività tumorale e ad un peggioramento della prognosi finale. Tuttavia ulteriori studi prospettici di alta qualità dovrebbero essere compiuti per poter considerare l’espressione di E-caderina come un fattore indipendente di prognosi nei pazienti affetti da carcinoma laringeo a cellule squamose.

OBJECTIVES: The aim of our study is to evaluate the influence of patient risk factors and the length of surgical time on the onset of BPPV (benign paroxysmal positional vertigo) and suggest surgical and clinical strategies to prevent this rare complication. METHOD: Our retrospective study analyzes that, in 2 years, 281 patients, divided into three groups, underwent wisdom teeth extraction, sinus lift elevation and orthognathic surgery, at the Oral and Maxillofacial Department of the University of Naples “Federico II.” RESULTS: Twenty-one patients presented postoperative BPPV. Some comorbidities, like dyslipidemia, high cholesterol levels, vascular problems, endocrinological disorders, perimenopausal age, female gender, cranial trauma, neurologic disorders, migraine, hypovitaminosis D, autoimmune disease, flogosis of inner ear, can be risk factors to the occurrence of postoperative vertigo. CONCLUSION: Our statistical analysis revealed a relationship between surgical time and comorbidity and onset of vertigo for each group of patients.

Diabetes mellitus is an independent risk factor for falling, particularly in the elderly. Due to chronic hyperglycemia and hyperinsulinemia patients with diabetes mellitus may have neurological deficits as peripheral neuropathy that is a debilitating micro-vascular complication affecting the proximal and distal peripheral sensory and motor nerves. Sensory neuropathy is prominent and represents the chief contributor to postural instability in diabetic subjects. Diabetic retinopathy is another complication consequent to a breakdown of the inner blood-retinal barrier with accumulation of extracellular fluids in the macula and growth of new vessels causing retinal detachment. Together peripheral neuropathy and retinopathy contribute to increase the risk of falls in diabetic patients, but a certain vestibular organs impairment should not be underestimated. Nevertheless, the exact mechanism and localization of peripheral vestibular damage consequent to chronic hyperglycemia and hyperinsulinemia are currently not still understood. Moreover it is not defined the possible role of these two blood conditions in worsening the prognosis of typical vestibular pathologies like "benign paroxysmal positional vertigo" and "Meniere disease". The aim of this review was to retrieve all studies investigating about the balance system alterations in patients suffering of diabetes. A search thorough Ovid MEDLINE was performed to enroll all eligible articles. Fourteen studies comprising a total of 1364 patients were included and analyzed in detail. On the basis of data reported in our review it appears plausible to hypothesize a direct connection among chronic hyperglycemic/hyperinsulinemic damage and peripheral vestibular organ dysfunction.

Objective Superior semicircular canal dehiscence (SSCD) represents a rare condition that may be associated to some particular symptoms as vertigo, autophony, and Tullio phenomenon. In those patients who present severe symptoms surgical treatment is required. Middle fossa craniotomy and transmastoid approaches are both described. Concerning repairing techniques, plugging and/or resurfacing are typically used to close the defect. Our aim was first to analyze the overall outcomes and complications of this surgery. Our second aim was to make a comparison between the different surgical modalities to investigate the eventual advantages and disadvantages. Review Methods A search through Ovid MEDLINE was organized in January 2015 to include all eligible articles. A statistical analysis of the obtained data was performed. Results Twenty studies comprising a total of 150 procedures were included. Four modalities of canal repair were described (plugging, capping, resurfacing, plugging with resurfacing). The overall rate of success resulted in 94% (95% confidence interval: 87%-97%). No statistically significant differences were observed among the different modalities of canal repair concerning both success rate and surgical complications. Differences observed between the middle fossa approach and transmastoid approach in terms of outcome were not statistically significant. Conclusions This review showed that surgical treatment for SSCD represents a safe option for those patients with severe symptoms of this condition. Differences observed in terms of success rate or complications were analyzed between the different surgical techniques with results that were not statistically significant.

The present study describes 3 patients of previous facial trauma who have subsequently been treated with functional endoscopic sinus surgery. The authors want pay attention on the possible correlation between facial trauma and sinusitis. Such fractures can be the cause of onset of paranasal sinusitis or of worsening of a previous sinusitis. The correlation between these 2 pathologies could be due to the fact that facial fractures concern the anatomic structures of paranasal sinuses. The damage to these structures during the facial trauma and tissue regeneration after injury or surgical treatment subverts the anatomy and function of the sinuses in a basically compromised situation.

This report shows an incidental finding of Warthin tumor in upper lip mucosa during hospitalization for a biting lesion of cheek mucosa MATERIALS AND METHODS: A 32-year-old male affected by a biting lesion of cheek mucosa was presented at Maxillo- Facial Unit of Federico II University. Clinical examination showed as an incidental finding a solid mass in the superficial layer of upper lip mucosa. We performed mini-invasive surgical treatment to obtain a radical excision of the cheek lesion at the same time as excision of Warthin tumor.a follow up of 12 months was performed. The complete healing of the two wounds was achieved, with no recurrence of any of the pathologies.The location of this Warthin tumor of minor salivary glands is very unusual. The role of imaging in diagnosis of Warthin tumor of minor salivary glands is to define localization, shape and dimension, contour, malignant features, nodal involvement. The role of fine needle aspiration cytology (FNAC) is critical in the diagnosis and therapy of minor salivary gland tumors. The surgical treatment in patients affected by Warthin tumour of minor salivary glands is local excision with a wide tumor free margin to prevent potential recurrence.Warthin tumor of minor salivary glands is a rare disease. We report a singular case of Warthin tumor localized in the upper lip mucosa, found as an incidental finding during a recovery for a biting lesion of cheek mucosa.Incidental finding, Minor salivary glands, Warthin tumor.Presentiamo un caso di Tumore di Warthin delle ghiandole salivari minori in un maschio adulto caucasico affetto da una lesione da masticamento della mucosa della guancia. L’esame clinico mostrava un riscontro accidentale di una massa solida situata nello strato superficiale della mucosa del labbro superiore. L’esame ecografico ha evidenziato una massa solida ipoecogena ben definita di circa 3x4 cm. Abbiamo eseguito un trattamento chirurgico mini-invasivo nel febbraio 2015 per ottenere una escissione radicale della lesione guancia e contemporaneamente del tumore di Warthin del labbro superiore senza recidiva della patologia.
