In this article, the bi-fenestral surgical chemical labyrinthectomy is introduced as a surgical demolition technique for treating resisting incurable forms of Meniere's disease in patients aged over 70 and/or with low hearing residues refractory to medical treatment.The results on participants fitting the inclusion criteria (n = 16) were reported using anamnesis (frequency of the crisis), Dizziness Handicap Inventory (DHI) and Functional Level Scale (FLS) before and after the intervention.Vertigo control was achieved in all patients of this case series. A difference of 57 and 3.67 in mean DHI (from 68 (SD 16.7) to 11 (SD 14)) and FLS (from 4.68 (SD 0.7) to 0.1 (SD 0.3)) scores respectively were seen after an average of 16.28 months. Contextually tinnitus was reported to improve in seven patients (43.75%), aggravate in three (18.75%) and remain unchanged in the remaining six (37.5%).Bi-fenestral surgical chemical labyrinthectomy appears a safe, immediate, and effective demolition treatment for vertigo control in a restricted class of patients affected by intractable Meniere disease.

Background: The present article aims to introduce the endolymphatic duct and sac decompression technique (DASD) and to give a spotlight on its benefits in Ménière’s disease (MD) treatment. Methods: Eighty-two patients with intractable MD which met the inclusion criteria were recruited and underwent DASD. This technique allows a meningeal decompression of the duct and the sac from the posterior cranial fossa to the labyrinthine block. The authors considered as main outcomes, the change of the dizziness handicap inventory (DHI) results, with the evaluations of the three sub-scales (Functional scale, Physical scale, and Emotional scale); ear fullness and tinnitus change on the perceptions of the patient; and hearing stage with four-Pure Tone Average (500 hz-1000 hz-2000 hz-4000 hz). The differences between the preoperative and the postoperative score were evaluated. A comparison with the literature was conducted. Results: After a 14-month follow-up, patients that underwent DASD reported a remarkable improvement of the symptoms in all three functional scales, confirmed by the total DHI. The difference between preoperative and postoperative scores is statistically significant. The data describe an ear fullness and tinnitus improvement. The multi-frequency tonal average before and after the surgery does not suggest a worsening of the value for any of 82 patients. Conclusion: The modification of sac surgery includes the endolymphatic duct in the decompression area allowing inner ear functional improvement, vertigo control, ear fullness improvement with minimal risk of facial nerve paralysis, and hearing loss. DASD is an improved old surgical technique.

Background.Video-assisted endoscopic radiofrequency inferior turbinate volume reduction (RFVTR) is one of the most common surgical therapies for inferior turbinate hypertrophy (ITH). Despite all the technical and surgical advancement, it is advisable to reduce as low as possible the intraoperative discomfort. The aim of this study is to evaluate the role of music in reducing patient discomfort during RFVTR.Materials and Methods.Twenty-three patients with chronic nasal obstruction due to ITH and candidate to RFVTR are included. Before the procedure each patient filled in a completed Italian version of the state anxiety questionnaire (State-Trait Anxiety Inventory), SNOT 22 questionnaire, VAS, and chose their favourite music to be played during RFVTR. All patients evaluate the intraoperative discomfort with a visual analog scale (VAS) and for each patient, vital parameters such as blood pressure and heart rate were recorded 15 minutes before the procedure, during and after RFVTR.Results.The intraoperative VAS scores during listening to music (5.7 ± 2.42 vs 6.7 ± 1.97; p< 0.05) were significantly lower, such as systolic BP (133.5 ±17.2 vs 136.78 ±16.8; p< 0.05) and heat rate (80.3 ±14.9 vs 81.7 ±15.5; p NS). During our survey, most of the patients preferred listening to classical music and none preferred rock music. No correlation was found between STAI 1-2 and intraoperative surgical discomfort evaluated both with VAS and cardiac parameters (systolic BP and HR).Conclusions.Music can be useful as a complementary method to control anxiety and reduce perception of pain in an office-based procedure, such as the RFVTR. The patient is more relaxed and experiences less discomfort; thus the surgeon and nurse can work with more confidence.

Objective Recently smartphones and tablets have spread in developed countries, and healthcare-related apps are growing incredibly in different specialties. The aim of this study is to provide an up-to-date review of the current OtoHNS (otolaryngology-head and neck surgery) apps developed for patients. Methods This mobile applications review was conducted in September 2017. Relevant apps about OtoHNS were searched in the Apple Store and in the Google Play using various keywords. We included helpful apps for OtoHNS patients. Apps for medical students, physician (95 apps) and non-English apps (6 apps) were excluded. Results At the end of our selection process, 216 apps have been included for mobile applications review. The number of apps published per year in OtoHNS has increased each year. The most common apps were about hearing, in particular 63 of 216 (29%) were hearing test; 75 of 216 (35%) for tinnitus treatment; 10 of 216 (5%) for sounds measurement around the patients; and 7 of 216 (3%) to treat vertigo. One hundred thirty-seven of 216 (63%) apps were free of charge. Physicians were clearly involved in the app's development in only 73 of 216 (34%) apps. One hundred sixty-three of 216 (75%) had no user ratings. Conclusions Apps are increasingly and easily accessible, although their use in clinical practice is not yet totally accepted. Our review showed that most apps have been created with no guidance from otolaryngologist. Further steps are needed to regulate apps' development. Hoping an "App Board," such as editorial board for scientific journal, to assess app quality, validity, and effectiveness before they can be fully incorporated into clinical practice and medical education.

Background Inflammatory disease of upper airway in pediatric population represents a social problem for both the pharmaco-economic impact and a burden for the family. To date, the use of topical therapies represents a significant therapeutic progress because they are able to reduce mucosal inflammation and improve tissue healing. Topical Hyaluronic Acid (HA) is a promising molecule that has been recently proposed as adjuvant treatment in the inflammatory disease of the upper aerodigestive tract (UADT) infections. Aims The aim of our work was to review the published literature regarding all the potential therapeutic effects of HA in the inflammatory disease of upper airway in pediatric population and evaluate the effectiveness of HA, alone or in combination, in children affected by cystic fibrosis. Methods Relevant published studies about use of HA in UADT in pediatrics were searched in Pubmed, Google Scholar, Ovid using various keywords with no limit for the year of publication. Studies based on the use of HA with nasal packing and with invasive administration of HA were excluded. Results At the end of our selection process, four publications have been included: one of them in children with recurrent upper respiratory tract infections, one of them in children with bacterial acute rhinopharyngitis, two of them in children affected by cystic fibrosis. Conclusions Topical administration of HA plays a pivotal role in all the children suffering from UADT inflammatory disease, and positive results are generally observed in children with cystic fibrosis.

The objective of this article is to systematically review the evidence on the effectiveness of vestibular rehabilitation (VR) in patients with benign paroxysmal positional vertigo (BPPV). Relevant published studies about VR in BPPV were searched in PubMed, Google Scholar and Ovid using various keywords. We included trials that were available in the English language and did not apply publication year or publication status restrictions. Studies based on the VR in other peripheral and/or central balance disorders are excluded. Primary outcome was the effect on vertigo attacks and balance. Of 42 identified trials, only 12 trials fulfilled our inclusion criteria and were included in this review. Three of them investigated the role of VR in patients with BPPV comparing with no treatment, two of them evaluated the efficacy of VR versus medications, seven of them have highlighted the benefits of the VR alone or in combination with canalith repositioning procedure (CRP) compared to CRP alone. The studies differed in type of intervention, type of outcome and follow-up time. VR improves balance control, promoting visual stabilization with head movements, improving vestibular–visual interaction during head movement and expanding static and dynamic posture stability. CRP and VR seem to have a synergic effect in patients with BPPV, especially in elderly patients. VR does not reduce the recurrence rate, but it seems to reduce the unpleasantness. So VR can substitute CRP when spine comorbidities contraindicate CRP and can reduce the uptake of anti-vertigo drugs post CRP. Further studies are needed to confirm these encouraging results.

Background This study was designed to prospectively evaluate the role of nebulized hyaluronic acid (HA) given for 10 days/mo over 3 months as adjunct treatment to minimize symptoms and preventing exacerbation of chronic rhinosinusitis (CRS). Methods Thirty-nine eligible patients were randomized to receive nebulized 9-mg sodium hyaluronate nasal washes plus saline solution (21 patients) or 5 mL of saline alone (18 patients), according to an open-label, parallel-group design, with blind observer assessment. A questionnaire about main CRS discomfort and nasal endoscopy for mucous discharge and/or mucosal edema of nasal cavities was used to assess primary outcomes of treatments. Secondary outcome measures included side effects and satisfaction. Results HA significantly improved quality of life in CRS patients according to the CRS questionnaire (16± 3.72 versus 11.52 ± 4.28; p < 0.001), contrary to saline group scores (18.92 ± 3.09 versus 18.21 ± 3.21; p = 0.55). The HA group showed significantly reduced osteomeatal edema (2.42 versus 1.52; p < 0.001) and secretions (0.95 versus 0.42; p < 0.001), whereas there was no statistically significant difference in the saline group he compliance to the treatment was similar in both groups and no side effects were recorded. Conclusion The results of this study suggested that intermittent treatment with topical 9-mg sodium hyaluronate plays a role in minimizing symptoms and could prevent exacerbations of CRS.

Complications of middle ear cholesteatoma are well described in the literature and are classified into two major categories: intratemporal and intracranial. They are due either to infection or to local extension of the disease and consequent invasion of surrounding tissues. We describe an unusual case of an extratemporal complication in a young woman who was treated at our service. Ten years previously she had undergone canal-wall-down tympanoplasty that did not achieve complete control of the disease. At this admission, the patient was found to have peculiar extension of the recurrent cholesteatoma into the temporozygomatic area. She underwent tympanoplasty of the canal wall using a targeted surgical technique. We resected the recurrent cholesteatoma en bloc without damaging the facial nerve despite extension of the mass to the ear and face. Follow-up was performed each year for 7 years without evidence of recurrence. Cholesteatomas are highly osteolytic, and extension of any residual cholesteatoma is unpredictable. Cholesteatoma of the middle ear requires a careful surgical approach to avoid complications, maintaining awareness of its possible extension into surrounding structures.

Canalolabyrinthine schwannoma is a rare subtype of neuroma. Only 1 case has been described in the literature. We report the clinical case of a 51-year-old Caucasian female with Meniere's disease-like symptoms. Magnetic resonance imaging showed right VIII cranial nerve schwannoma that had different characteristics from the classical described types. The peculiar features of our case of intralabyrithine canalolabyrinthine schwannoma directed the surgeon and radiologist to tailored considerations for follow-up and therapy.

The aim of the present study is to measure sound sensitivity of the saccule for low frequencies in a population of both young and adult prelingual deaf patients using cervical Vestibular Evoked Myogenic Potentials (cVEMPs) and to correlate the findings obtained with the phonological features. The sensitivity of the saccule to sound stimuli is well known in previous studies. The functional role of the human saccule in responding to sound stimuli is still unclear. The study was conducted on a control population of young and adults with normal hearing. The outcomes showed that the amplitude of myogenic vestibular evoked potentials resulted the most significant parameter, indicating the degree of saccular response. We found in the group of deaf adults that the saccule retained an unaltered responsiveness to sound stimuli, without suffering the age-related functional decrease as demonstrated in normal hearing patients. We assumed that the high saccular response in deaf patients is determined by a constant somatosensory stimulation (rehabilitation) of the saccule, represented by the phonetic training. We correlated the phonetic features typical of the deaf with the sensitivity of the saccule to low frequencies. Such sensitivity makes this organ the ending point of the phonetic information (perception) but also the starting point of its regulation (production). Our experience demonstrates the phonetic role of saccule in the regulation of the human voice and provides the basis for further development of this topic. Thus we strongly believe that in the deaf the saccule plays a compensatory role. The high response of the saccule allows phonemic self-regulation, compensating the low/absent tone-verbal feedback. The saccule would come rightfully to be the accessory inner ear in deaf patients. We recommend the cVEMPs in the audio-phonological assessment before starting the speech therapy or during treatment to assess the degree of responsiveness of the saccule. The resulting data would give an extremely useful information that could be ignored by the pure tone audiometry. The presence of the cVEMPs in the deaf patient may improve the expectation of the performance of speech therapy.

The authors performed a prospective study to evaluate postural variations arising after reduction mammaplasty, objectively recorded by means of static stabilometry. Thirty consecutive patients affected by various degrees of breast hypertrophy were enrolled in the study. Obesity, orthopedic, and otoneurologic diseases were the exclusion criteria. Postural function was evaluated with static stabilometry preoperatively and 1 and 6 months postoperatively. Patients were grouped according to age, sternal notch-nipple distance, and glandular resection and general and subgroup statistical analysis using Student t test for paired samples were performed. Statistically significant differences were found only after 6 months (P = 0.026). In the subgroup analysis, statistically significant differences were found for the age group >35 years (P = 0.0237) and for the sternal notch-nipple distance >30 cm (P = 0.0320). Stabilometry objectively demonstrated postural improvement perceived following breast reduction. Age and ptosis degree appeared to influence posture more than the entity of resection.

Nasal polyps (NP) are common benign degeneration of nasal sinus mucosa with a prevalence around 4% in the adult population. The causes are still uncertain but there is a strong association with allergy, infection, asthma and aspirin sensitivity. Histologically, the presence of a large quantity of extracellular fluid, mast cell degranulation and eosinophilia has been demonstrated. Typically the patients show nasal obstruction, anosmia and rhinorrhoea. Nasal endoscopic examination and CT imaging allow evaluation of the disease extension. A combined medical and surgical treatment is recommended for symptoms control in preventing symptomatic NP recurrence. We will review the current knowledge in the pathogenesis and treatment of this complex disease entity.

Background Nasal obstruction is one of the most frequent symptoms in the ear, nose, and throat (ENT) setting. It can be evaluated either subjectively or objectively. In a subjective way, a visual analog scale (VAS) and the Sino-Nasal Outcome Test 20 (SNOT 20) can rapidly quantify the degree of obstruction, whereas the most commonly used objective methods are nasal endoscopy and active anterior rhinomanometry (AAR). It is still a matter of controversy to what extent the sense of nasal obstruction is associated with objective measures for nasal space and airflow. The aim of the study was to evaluate nasal breathing before and after functional nasal surgery by video-rhino-hygrometer (VRH) comparing the results with widely accepted methods. Methods Twenty patient candidates for septoplasty and inferior turbinate reduction were included in the study. SNOT-20, VAS, nasal endoscopy, and AAR were analyzed and compared with VRH values. Results Before surgery VRH showed variability of nasal respiratory flow between individuals and between nostrils. After surgery we had an increase (p < 0.05) of airflow in both nostrils. VRH data were found to be correlated with VAS and SNOT-20 values (p < 0.05) both pre- and postoperatively. Despite the statistically significant correlation of AAR with SNOT-20 and VAS, no statistically significant correlation between AAR and VRH was found. Conclusion VRH provides an immediate, easy, and noninvasive assessment of nasal respiration. For these reasons it can be used, in association with rhinoscopic data and other instrumental tests, to evaluate nasal breathing in daily ENT practice.

To date, surgical dissection is based only on mechanical forces. The use of a chemical product that is able to ease tissue dissection represents an important advance. MESNA (sodium-2-mercaptoethanesulfonate) has recently been validated for chemically assisted tissue dissection during surgery or invasive procedures. No other drugs are available for this.An extensive literature search was conducted that included published articles and abstracts on the use of MESNA during surgery or invasive procedures in the experimental and clinical setting, since 1997. Clinically validated settings are ear, nose and throat (ENT), gynecological and orthopedic fields.A state-of-the-art overview of intraoperative applications of MESNA, and a consideration of the possible mechanisms underlying chemically assisted tissue dissection.MESNA has been successfully used to ease abdominal myomectomies and excision of endometrial cysts; in ENT surgery, topical MESNA could be widely used, from ear and skull base to head and neck diseases, in both outpatient and operating-room settings. In revision lumbar spine surgery, its use resulted in significantly easier surgery and reduction of postoperative complications. Given the high efficacy and favorable complications rate, future applications in the surgical field are expected to increase.

Objectives:We recorded and compared the vestibular evoked myogenic potentials (VEMPs) before use of an endolymphatic mastoid shunt (EMS) and 1, 12, and 48 months after placement of the shunt.Methods:Air-conducted VEMPs were recorded in 28 patients affected by intractable Meniere's disease and treated with placement of an EMS.Results:One month and 12 months after the surgery, VEMPs were not detectable in the operated ear in 100% and 86% of the patients, respectively. Forty-eight months after the surgery, they were elicited in 79% of the patients.Conclusions:We conclude that VEMPs are a clinically useful tool in the postoperative follow-up of patients with an EMS.

Obstructive sleep apnea syndrome (OSAS) is a complex chronic clinical syndrome, characterized by snoring, periodic apnea, hypoxemia during sleep, and daytime hypersomnolence. It affects 4-5% of the general population. Racial studies and chromosomal mapping, familial studies and twin studies have provided evidence for the possible link between the OSAS and genetic factors and also most of the risk factors involved in the pathogenesis of OSAS are largely genetically determined. A percentage of 35-40% of its variance can be attributed to genetic factors. It is likely that genetic factors associated with craniofacial structure, body fat distribution and neural control of the upper airway muscles interact to produce the OSAS phenotype. Although the role of specific genes that influence the development of OSAS has not yet been identified, current researches, especially in animal model, suggest that several genetic systems may be important. In this chapter, we will first define the OSAS phenotype, the pathogenesis and the risk factors involved in the OSAS that may be inherited, then, we will review the current progress in the genetics of OSAS and suggest a few future perspectives in the development of therapeutic agents for this complex disease entity.

Sinonasal mucosal melanoma (MM), although very rare (

Rheumatoid arthritis (RA) patients present with both conductive and sensorineural deafness.To evaluate the prevalence and features of hearing impairment in patients with RA.A total of 28 RA patients underwent a rheumatological evaluation, including determination of rheumatoid factor, protein 2-glycoprotein I level and the Lee index. An audiological assessment consisting of pure-tone audiometry (PTA) and determination of auditory brainstem responses (ABRs) and transient evoked otoacoustic emissions (TEOAEs) was performed. The results were compared with those of 28 age- and sex-matched healthy subjects. Four selected RA patients underwent stapedectomy; PTA and TEOAEs were evaluated 6 months postoperatively.Increased air conduction thresholds at 250, 500 and 1000 Hz were found in RA subjects in comparison to controls (p0.001). RA patients showed higher air-bone gaps in PTA (p0.05) and an increased Wave I latency in ABRs (p=0.03). Decreased reproducibility (p0.001) and amplitude (p0.001) of TEOAEs were found in RA subjects in comparison to controls. A significant correlation between disease duration and echo amplitude was noticed (r=0.389). After stapedectomy, a reduction in the air-bone conduction gap (11 vs 2 dB HL) was noticed; no significant difference in TEOAEs was found.

Background We prospectively evaluated the efficacy of hyaluronic acid (HA) as an adjuvant treatment to hasten the improvement of nasal respiration and to minimize patients’ discomfort in the postoperative radiofrequency volumetric tissue reduction (RFVTR) of inferior turbinates. Methods We enrolled 57 patients randomly assigned into two groups, HA (22 patients) and saline group (35 patients), which received isotonic saline nasal irrigation. We used the monopolar device somnoplasty for all patients. Visual analogic scale (VAS) and nasal endoscopy were used to assess the outcomes of the treatments during the 1st month of follow-up. Results The mean VAS score of the HA group at the 1st week was significantly lower than the control group (3.36 ± 1.89 versus 6.95 ± 1.52; p < 0.05). The VAS score remained significantly lower in the HA group also at the 2nd week (3.43 ± 1.27 versus 5.75 ± 1.39; p < 0.05), becoming similar to the control group at the 4th week (p = ns). Since the first visit the HA group also showed significantly lower crust score than the saline group (p < 0.05), and there was no crust found in either group at the last visit. The compliance to treatment was similar in both groups. Conclusion The results of this prospective study suggest a role of HA as a supportive treatment for faster improvement of nasal respiration, also minimizing patients’ discomfort in postoperative nasal surgery, promoting nasal mucosa healing in postoperative RFVTR for inferior turbinate hypertrophy.

Objectives/Hypothesis: The objective of the study was to evaluate the efficacy of three therapeutic strategies (Semont maneuver, flunarizine, and no treatment) in patients with benign paroxysmal positional vertigo. Study Design: Randomized prospective trial. Methods: One hundred fifty-six consecutive patients older than 60 years of age who were affected by benign paroxysmal positional vertigo of the posterior semicircular canal were enrolled. The diagnosis was made on the basis of the history of recurrent sudden crisis of vertigo and positional-induced typical nystagmus after Dix-Hallpike positioning maneuver. Patients were randomly allocated to receive Semont liberatory maneuver (intended as a statoconiadetachment maneuver), flunarizine, or no treatment. A post-treatment negative Dix-Hallpike test result was considered as a proof of vertigo resolution. Results: Cure rates with Semont maneuver were significantly higher (94.2%) than those obtained with flunarizine (57.7%) and no treatment (36.4%) (P

Purpose The aim of this study was to evaluate poststapedectomy-delayed facial palsy etiopathogenesis, risk factors, evolution, and prevention. Materials and methods Seven hundred six stapedectomies performed in 580 patients were reviewed. In all patients who developed delayed facial palsy, the dates of onset and subside of facial palsy, the anatomic and pathologic predisposing factors, and a possible history for recurrent labial herpetic lesions were considered. The House-Brackmann (H-B) grading system was used to evaluate the facial function. Virus-specific immunoglobulin (Ig) G and IgM antibodies against herpes simplex virus type 1 (HSV-1) were determined by enzyme-linked immunosorbent assay (ELISA) 3 weeks after the onset of the paralysis. The results were compared with a control group without a history of recurrent herpes labialis. Results Poststapedectomy facial palsy developed in 7 out of 706 procedures. All 7 patients referred a history of recurrent labial herpetic lesions. One patient showed a facial palsy H-B grade II, 2 a grade III, and 3 a grade IV. After acyclovir therapy, 6 subjects recovered completely, whereas 1 maintained an H-B grade II. An increased IgG antibody titer was found in 6 of the patients with delayed facial palsy and in 1 out of 7 controls. Mean IgG titer was 1:14,050 in the subjects with delayed facial palsy and 1:2,300 in controls (P Conclusions Poststapedectomy-delayed facial palsy is likely caused by a reactivation of HSV-1, latent within the geniculate ganglion. The activation of the latent virus is more frequent in patients with a history of herpes labialis and can be prevented by an adequate acyclovir therapy.

35delG is the most common mutation in the Connexin-26 gene, representing a major cause of autosomal recessive hearing loss. The aim of this study was to evaluate the relationship between the audiological phenotype and the 35delG mutation in 64 Sicilians with non-syndromic deafness. Pure-tone audiometry and a screening for 35delG mutation were performed. Audiograms were evaluated according to the classification of Liu and Xu. Thirteen homozygotes and nine heterozygotes for the investigated mutation were found. Symmetrical hearing loss was significantly (p=0.008) more common in homozygous subjects than in those without the Connexin-26 mutation. Profound-severe hypoacusia was found in 92.3 per cent of 35delG homozygous, 22.3 per cent of heterozygous and 58.7 per cent of 35delG absent patients. Residual shape audiograms were more frequent in homozygotes. A molecular analysis for the 35delG mutation should be performed in cases of symmetric, severe-profound congenital hearing loss, as a genetic cause is probable in such cases.

Stapes surgery in relation to age This prospective study aims to evaluate the efficacy of stapedotomy in relation to age. Eighty-four ears of 82 consecutive patients who underwent stapedotomy were studied. Patients were divided into five groups according to their age. In each patient, we evaluated the pre- and postoperative auditory thresholds, according to the Committee on Hearing and Equilibrium of the American Academy of Otolaryngology – Head and Neck Surgery guidelines. Statistically significant (P

Nerve growth factor (NGF) is a neurotrophin which promote and regulate the survival of neurons in the peripheral nervous system. We aimed to evaluate the nasal NGF expressions of mast cells in healthy patients after stimulation with sterilized isotonic solution delivered at high pressure.The first part of the study was made with 21 voluntary individuals. The middle third of the inferior turbinate epithelial cells on the right nostril was scraped using a sterile curette and indicated as (pre), than a spray of sterilized isotonic solution at high pressure on the left nostril was delivered and 25 minutes later a similar stimulation was delivered on the same nostril. The stimulation was made with a specific spray. The middle third of the inferior turbinate epithelial cells on the left nostril was scraped using a sterile curette and indicated as (post).Forced nasal stress induced by local delivery of high pressure physiological solution causes an increase in the number of mast cells and enhances level of NGF in the nasal fluid compared to the control subjects. So based on the first part of our study, since NGF is universally known as effective in protection and repairing of neural cells damage, we started the second part and gave a treatment on the same patients, to increase NGF levels with a six months daily therapy and observed the variations in Sensorineural Hearing Loss (SNHL) and tinnitus intensity from the beginning to the end of the therapy. All patients received sterilized isotonic solution at high pressure (pression emission level: PEL): 7 g/sec for 0.5 sec (emission time: ET) in both nostrils. 25 minutes later a similar stimulation was delivered twice a day. The control group (21 pts) received normal therapy with betahistine dihydrochloride 16 mg twice a day.Upon acuphenometry, there was a lower intensity of tinnitus and the improvement was signaled by the patients. Patients with SNHL treated with conventional therapy had a slight worsening, while the patients treated with our new therapy which increased NGF levels, showed improvement of hearing. This new therapy represents a new therapy of SNHL, tinnitus and hearing disorders.

to determinate the role of heterozygosis of M34T mutation of GJB2 gene in non syndromic congenital deafness.retrospective study between March 2010 and June 2013. Molecular screening for 35delG and M34T mutations of the GJB2 gene was offered to all women undergoing to second trimester genetic amniocentesis. Patients were excluded from the study group if one of the following conditions were present: infections, fetal abnormalities, family history for congenital deafness, diagnosis of chromosomal abnormalities, and consanguinity between parents.a total of 12.472 Caucasian women gave informed consent for this test. Seventy-seven cases were excluded. From the 12.395 amniotic fluid analysis remained, the following was found: 2 cases of 35delG homozygosis and 352 cases of heterozygous carriers (42 M34T mutation, 298 35delG mutation, 12 double heterozygosis M34T/35delG). The follow up in first year of life in the 42 newborns with heterozygosis for M34T mutation showed a mild deafness in 23 cases.in our series, presence of heterozygosis M34T mutation is associated in more than 50% of cases to mild congenital deafness.

Acrylic hydrogels, like the polymer of 2-hydroxyethyl methacrylate, are biocompatible, mechanically stable, porous materials that can be coated with collagen or laminin acting as bioadhesive substrates. Poly-2-hydroxyethyl methacrylate sponges have been proposed for restoring the anatomical continuity of damaged neural structures. In the present work, the ability of poly-2-hydroxyethyl methacrylate sponges to provide the injured spinal cord neurons with a conductive substrate for their regenerating axons was investigated in 32 adult Wistar rats. Collagen impregnated poly-2-hydroxyethyl methacrylate sponges were implanted into suction cavities of the dorsal funiculus of the spinal cord. Two to four months after implantation, the spinal cord was removed and processed for histology, and S100 and GFAP immunohistochemistry. To study axonal regeneration into the sponge, the spinal cord or the sensorimotor cortex were injected with 0.05-0.1 microl of an 8% solution of lectin-conjugated horseradish peroxidase or 10% dextran tetramethylrhodamine. The fibroglial reaction, accumulation of mononuclear cells, and angiogenesis at the interface between the spinal cord and the sponge were minimal. Cystic cavitation in the spinal cord was virtually absent. Anterograde labeled axons were seen to penetrate and to elongate the full length of the sponge. These results demonstrate that poly-2-hydroxyethyl methacrylate sponges represent a safe supportive material for regenerating spinal cord axons.

BACKGROUND. The endoscopic endonasal transclival approach (EETCA) is a minimally-invasive technique allowing a direct route to the base of implant of clival lesions with reduced brain and neurovascular manipulation. On the other hand, it is associated with potentially severe complications related to the difficulties in reconstructing large skull base defects with a high risk of postoperative cerebrospinal fluid (CSF) leakage. The aim of this paper is to describe a precise layer by layer reconstruction in the EETCA including the suture of the mucosa as an additional reinforcing layer between cranial and nasal cavity in order to speed up the healing process and reduce the incidence of CSF leak. METHODS. This closure technique was applied to the last six cases of EETCA used for clival meningiomas (2), clival chordomas (2), clival metastasis (1), and craniopharyngioma with clival extension (1). RESULTS. After a mean follow-up of 6 months we had no one case of postoperative CSF leakage or infections. Seriated outpatient endoscopic endonasal controls showed a fast healing process of nasopharyngeal mucosa with less patient discomfort. CONCLUSIONS. Our preliminary experience confirms the importance of a precise reconstruction of all anatomical layers violated during the surgical approach, including the nasopharygeal mucosa.

Congenital agenesis of the parotid gland is a rare entity whose etiopathogenesis is still unclear. It is usually bilateral and is sometimes associated with other developmental anomalies of the head and neck region. A case is presented in which aplasia of the right parotid gland was associated with an omolateral angioma of the cheek. The radiological diagnostic approach and a review of the literature on agenesis of the salivary glands are presented.

Treatment of vestibular schwannomas presents many controversial aspects, from the indication to the selection of the best treatment option. In the era of stereotactic radiotherapy, microsurgery has to be competitive in terms of providing the best chances of functional preservation and complete tumor removal. The two most commonly used surgical approaches are the retrosigmoid suboccipital and the presigmoid translabyrinthine. We describe the endoscopy-assisted presigmoid retrolabyrinthine approach (EAPRA) aiming at combining the advantages of the retrosigmoid and translabyrinthine techniques. For 2 years (from May 2009 to June 2011), the EAPRA was used to remove medium to large sporadic vestibular schwannomas in ten patients. Complete tumor removal was obtained in eight patients, postoperative transient facial nerve function impairment or worsening was observed in two, and one had hearing deterioration postoperatively. No threatening complications occurred after surgery, and the length of hospitalization was usually less than 10 days. The EAPRA can provide direct access to the CPA along with labyrinthine complex conservation, allowing hearing function preservation and minimal cerebellar retraction. Endoscopic assistance is a crucial adjunct in the presigmoid retrolabyrinthine approach in order to address the limits imposed by labyrinthine complex preservation. It ensures complete visualization of the intracanalicular portion of the schwannoma, thus improving the rate of a radical tumor resection. The EAPRA could represent a valid surgical option in vestibular schwannoma surgery.

Fully implantable Cochlear Implants (CIs) would represent a tremendous advancement in terms of quality of life, comfort and cosmetics, for patients with profound sensorineural deafness. One of the main challenges involved in the development of such implants consists of finding a power supply means which does not require recharging. To this aim an inertial Energy Harvester (EH), exploiting the kinetic energy produced by vertical movements of the head during walking, has been investigated. Compared to existing devices, the EH needs to exploit very low frequency vibrations (

The transduction mechanism of the inner ear and the transmission of nerve impulses along the auditory way are highly dependent upon the cochlear oxygen supply. Several studies have considered the possibility that obstructive sleep apnea–hypopneas during sleep can interfere with these processes, and the results are not uniform. The aim of the study is to evaluate the auditory function in adult patients affected by severe obstructive sleep apnea syndrome (OSAS). Thirty-nine patients in this study were included and divided in OSAS group, with severe OSAS (Apnea–Hypopnea Index, AHI > 30), and control group with snoring without OSAS (AHI

Isolated malleus fracture is a rare clinical entity, and usually the handle of the malleus is involved. We report a video, to our knowledge the first in the literature, of a diagnostic otoscopy of a malleus fracture showing the movement of a left fractured malleus handle during a Valsalva maneuver (see the video online at www.laryngoscope.com).

Conclusion. Logon is superior to click to trigger larger and more consistent vestibular evoked myogenic potentials (VEMPs). Objectives. To record and compare the parameters of VEMPs evoked by bone- and air-conducted logon (l-VEMPs) and click (c-VEMPs). Subjects and methods. Air- and bone-conducted l-VEMPs and c-VEMPs were recorded in 28 normal ears with an Amplaid MK12 (Amplaid, Milan) equipment. Results. VEMPs response rate was 100% with both air-conducted logon and click, while l-VEMPs showed a higher response rate (79%) in comparison with c-VEMPs (21%) with bone-conducted stimuli. A significant (p

We report 44 cases of monomorphic adenoma (MA) of the major salivary glands observed during the years 1979–1989. All of these tumours were reviewed and classified on the basis of the World Health Organisation (WHO) criteria. Histological type, site, sex and age were considered. 34 cases of adenolymphoma were observed, all of them located in the parotid glands; 10 MA without lymphoid stroma were located in both parotid and submandibular glands. Distinctive histological and clinico-pathological features of the latter group of tumours are discussed, as well as the diagnostic criteria in distinguishing these tumours from pleomorphic adenoma and adenoid-cystic carcinoma.

Politzer manoeuvre causes retrograde inflation of the middle ear by forcing air through the Eustachian tube. It has been proposed as nonsurgical treatment of middle ear with effusion, Eustachian tube dysfunction and negative middle ear pressure from elevation changes. Even if Politzer manoeuvre can be considered a classical technique, it is generally performed without any feedback about its correctness neither about qualitative evidence about its efficacy. In this paper we describe an innovative device, named OtoFree, specifically designed to support medical doctors during Politzer manoeuvre. OtoFree provides information about the correctness of the manoeuvre and also useful hints about the treatments results.
