Abstract
OBJECTIVES Despite recent advances in biomolecular research that have improved our knowledge of cholesteatoma pathogenesis, the reasons behind its highly variable clinical course are still not clarified. It has been proposed that biological signaling between peri-matrix and matrix cells could play a critical role in disease homeostasis. The aim of our study was to analyze the expression of inflammatory (IL-1β), hyper-proliferative (STAT-3, TGF-β), and angiogenic (VEGF-C, PDGFr) factors in congenital and acquired cholesteatomas (both in adults and children), which might correlate with the clinical features observed. We performed an experimental study on 37 patients (29 males and 8 females, ranging from 4 to 66 years of age) who were diagnosed with cholesteatoma between 2020 and 2021 in our institution. All patients underwent clinical, audiologic, and radiologic assessments. Bone erosion grading and staging of cholesteatoma growth were assessed through preoperative evaluation and intraoperative middle ear findings, according to the PTAM System proposed by the Japan Otological Society (2016). Retro-auricular skin specimens were intraoperatively collected in all patients. Skin and cholesteatoma samples were analyzed through histopathological, western blot, and immunohistochemical evaluations. The expression rate was measured to find out the differences between congenital and acquired cholesteatomas as well as between the adult and pediatric populations. Expression of angiogenic, inflammatory, and proliferative biomarkers is significantly increased in acquired cholesteatomas in children as compared to congenital and acquired forms in adults, in accordance with the higher stage of disease shown by imaging, surgical, and histological features. Our data suggest that pathways already supposed to be involved in the pathogenesis of cholesteatomas could be differently activated in more destructive forms, typically found in children. The identification of potential biomarkers of cholesteatoma aggressiveness could lead to more personalized management (timing of intervention, recurrence prevention) and the future identification of anti-growth/anti-proliferative agents as non-surgery therapeutic options.

Abstract
Background and aim Acute mastoiditis (AM) is a common complication of acute otitis media in children. There is currently no consensus on criteria for diagnosis. Head CT is the most frequent diagnostic tool used in the ED although the increasing awareness on the use of ionized radiations in children has questioned the use of CT imaging versus solely using clinical criteria. Our research aimed to understand if CT imaging was essential in making a diagnosis of AM. Methods We retrospectively analyzed medical records from pediatric patients who accessed our Pediatric Emergency Department (ED) between January 2014 and December 2020, with a clinical suspicion of AM. We reviewed clinical symptoms upon presentation, head CT and lab values (white blood cell count or WBC, C-Reactive Protein or CRP) when done, presence of complications and discharge diagnosis. A multilogistic regression model was specified to establish the role of clinical features and of CT in the diagnosis of AM based on 77 patients. Results Otalgia (OR= 5.01; 95% CI= 1.52-16.51), protrusion of the auricle (OR= 8.42; 95% CI= 1.37-51.64) and hyperemia (OR= 4.07; 95% CI= 1.09-15.23) of the mastoid were the symptoms strongly associated with a higher probability of AM. In addition to clinical features, the adjusted OR conferred by head CT was 3.09 (95% CI = 0.92-10.34). Conclusions Clinical signs were most likely predictive of AM in our sample when compared to Head CT. Most common symptoms were protrusion of the auricle, hyperemia or swelling behind the ear and otalgia.

Abstract
Management of vestibular schwannoma (VS) is a complex process aimed at identifying a clinical indication for fractionated stereotactic radiotherapy (sRT) or microsurgical resection or wait and scan (WS). The aim of the review was to clarify which patient and tumor parameters may lead to different therapeutic choices, with a view to a personalized VS approach. A systematic review according to Preferred Reporting Items for Systematic Review and Meta-Analysis criteria was conducted between February and March 2022. The authors defined six parameters that seemed to influence decision-making in VS management: 1-incidental VS; 2-tumor size; 3-tumor regrowth after sRT; 4-subtotal resection; 5-patients' age; 6-symptoms. The initial search yielded 3532 articles, and finally, 812 articles were included. Through a qualitative synthesis of the included studies, management strategies were evaluated and discussed. An individualized proposal of procedures is preferable as compared to a single gold-standard approach in VS decision-making. The most significant factors that need to be considered when dealing with a VS diagnosis are age, tumor size and hearing preservation issues.

Abstract
PURPOSE Irreversible bilateral sensorineural hearing loss is a common side effect of platinum compounds. Because of the extended overall survival, a prolonged hearing surveillance and management of hearing impairments are emerging concerns for pediatric oncology. METHODS In this retrospective observational study, we enrolled 38 children out of 116 treated at our institution by chemotherapy (cisplatin and/or carboplatin) with or without irradiation between 2007 and 2014, submitted to hearing monitoring before every cycle of chemotherapy, and who completed a 5-year long-term audiological follow-up. Chemotherapy regimens, demographic findings, cumulative doses, and cranial irradiation were compared. RESULTS At the end of 5-year follow-up, ototoxicity was significantly increased compared to that observed at the end of chemotherapy (52.5% vs 39.5%, p < 0.001). A late onset of hearing loss was experienced in 13.1% of children, while in 26.3% progressive hearing loss was measured. Deafness at the end of chemotherapy and irradiation were significant prognostic factors for late ototoxicity outcomes (Odds Ratio 7.2-CI 1.67-31.1-p < 0.01 and 5.25-CI 1.26-21.86-p < 0.01 respectively). No significant differences were found between cisplatin and combined treatment (i.e., cisplatin shifted to carboplatin during monitoring for the onset of ototoxicity) and ototoxicity was not associated with platinum compounds cumulative dose (p > 0.05). 13.1% of children needed hearing aids at the end of follow-up. CONCLUSION Long-term monitoring of at least 5 years prevents the harmful effects of hearing deprivation identifying late onset/progressive hearing loss after platinum compound chemotherapy in children thanks to early hearing rehabilitation, especially in those who underwent multimodal therapy or subjected to irradiation.

Abstract
BACKGROUND Management of vestibular schwannoma (VS) is a complex process aimed at identifying a clinical indication for fractionated stereotactic radiotherapy (sRT) or radiosurgery, microsurgical resection, or wait and scan (WS). We describe the experience of our VS multidisciplinary team (MDT) at a tertiary university referral center created for diagnosis, treatment, and follow-up of VS patients. METHODS We conducted a retrospective study on 132 consecutive patients referred to the MDT and managed by observation (WS), microsurgery, or fractionated sRT. The analysis included patient age, tumor size, hearing level, facial nerve function, tumor control, complications, and quality of life questionnaires. RESULTS Among the patients, 21% were subjected to microsurgery, 10% to sRT, and 69% to WS. The median follow-up time was 30 months. Outcomes based on different management modalities are described. Statistically significant differences among groups were detected in terms of quality of life (physical domain). CONCLUSIONS MDT may provide the best individualized therapy for VS patients compared with a single gold-standard strategy.

Abstract
OBJECTIVES Tinnitus is a common symptom largely impactful on quality of life, especially in the elderly. Our aim was to evaluate the efficacy of self-administered screening tests to correlate the severity of subjective perception of tinnitus with emotional disorders and the overall cognitive status. METHODS Patients aged ≥ 55 years with chronic tinnitus were recruited and submitted to a complete audiological evaluation; Tinnitus Handicap inventory (THI); Hospital Anxiety and Depression Scale (HADS-A and HADS-D) and Mini-Mental State Examination (MMSE). Demographic and audiological features of patients with and without cognitive impairment (MMSE score cut-off of 24/30) were analyzed in order to reveal the relationship among tinnitus, emotional disorders, and cognitive dysfunction. RESULTS 102 patients were recruited (mean age: 70.4 ± 9.6). THI score was directly related to HADS-A score (r = .63) HADS-D score (r = .66), whereas there was no relationship between tinnitus severity and MMSE (r = .13). CI and n-CI groups did not differ in the characteristics of tinnitus (p > .05), however, hearing threshold (p = .049) and anxious depressive traits measured with HADS-A (p = .044) and HADS-D (p = .016) were significantly higher in the group with cognitive impairment. Furthermore, age ≥ 75 years (p = .002, OR = 13.8), female sex (p = .032; OR = 6.5), severe hearing loss (p = .036; OR = 2.3), and anxiety (p = .029; OR = 9.2) resulted risk factors for CI. Therefore, in CI group MMSE score was inversely related to age (r = -.84). CONCLUSIONS Cognitive impairment and psychiatric discomfort should be considered in tinnitus patients, related to increasing age, female sex, and severe hearing loss. Thus, self-administered questionnaires can be useful in addressing clinical approach.

Abstract
BACKGROUND Allergic rhinitis is a common childhood disease responsible for a major impact on quality of life and healthcare resources. Many hypotheses have been proposed to explain the link between allergy and otitis media, although a definitive mechanism has not been identified yet. One of the major critical points is that authors failed in distinguishing among different phenotypes of middle ear inflammation. This review pointed out literature evidence from the laboratory and clinical experience linking allergy to different phenotypes of otitis media in children. METHODS We performed a systematic review in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) process. Our search yielded 3010 articles that were finally screened. This resulted in 20 manuscripts of which the full texts were included in a qualitative analysis. We paid particular attention in distinguishing among phenotypes of otitis media. RESULTS Clinical evidence and analyses of biomarkers suggested that allergy may be linked to some phenotypes of otitis media and, in particular, to otitis media with effusion (OME) and acute re-exacerbations in children with middle ear effusion. It was not possible to perform the analysis for allergy and acute and chronic otitis media because of paucity and heterogeneity of data. CONCLUSION Allergy should be considered in the diagnostic workup of children with OME as well as OME should be excluded in children with persistent moderate to severe AR. In these cases, clinicians should evaluate prompt and accurate treatment of allergy in improving outcomes, although futures studies are required to increase evidence supporting that anti-allergy treatment may be effective in the recovery and outcome of otitis media with effusion.

Abstract
OBJECTIVE Benign paroxysmal positional vertigo (BPPV) is the most common cause of vestibular vertigo, with post-traumatic origin in about 15% of cases. Management and prognosis of traumatic BPPV (T-BPPV) are still debated, especially about recurrence. The aim was to compare T-BPPV to idiopathic (I-BPPV). DESIGN AND STUDY SAMPLE We analysed data about 795 BPPV patients: 716 idiopathic (90%) and 79 post-traumatic (10%), evaluating clinical history and bedside-examination, treating all patients with repositioning manoeuvres and reassessing them until the resolution of symptoms and nystagmus. RESULTS Persistence rate in T-BPPV and I-BPPV patients was significantly different (p = 0.0074, OR = 2.31), respectively 12.6% and 5%. Also the rate of bilateral disease (p = 0.0063, OR = 4.72) and multicanalar involvement (p = 0.0183; OR = 4.67) were significantly higher in T-BPPV patients . There were no significant differences in age and sex distribution, side and canal interested. In T-BPPV group, the resolution rate with one manoeuvre was lower than I-BPPV (p = 0.0132: OR: 0,56). Recurrence rate was 38% in the T-BPPV group and 30.6% in the I-BPPV group, without significant difference. CONCLUSIONS T-BPPV resulted different from I-BPPV in the resolution rate, bilateral or multiple canal involvement and persistence rate. T-BPPV and I-BPPV does not differ for recurrence rate, suggesting that, after resolution, the natural course of post-traumatic and idiopathic BPPV is similar.

Abstract
INTRODUCTION Stapes surgery is a safe procedure, with favourable hearing outcome. The objective of the study is to assess the long-term hearing results, addressing the bone conduction (BC) decay and the need for hearing aids in otosclerosis patients. METHODS We enrolled patients who underwent stapes surgery by means of stapedectomy or stapedotomy between 1991 and 2001. All enrolled patients underwent pure-tone audiometry (PTA) between September 2017 and June 2018. A set of questions was administered to record the prevalence of subjective symptoms and the need for hearing aids. RESULTS Seventy patients were enrolled for a long-term evaluation; 37 patients underwent bilateral surgery; therefore, 107 ears were included in the analysis. The average follow-up period was 22 years. No statistically significant difference was found between early and late post-operative air conduction (AC) PTA (41 vs. 49 dB; p > 0.05) nor between early and late post-operative BC-PTA (29 vs. 37 dB; p > 0.05). A significant difference was observed for AC at 8 kHz (65 vs. 78 dB; p < 0.05) and BC at 2 and 4 kHz (28 vs. 40 dB and 45 vs. 58 dB, respectively; p < 0.05). CONCLUSIONS This is, to our knowledge, the longest mean follow-up time in the literature. A mild decrease in both AC and BC threshold can be expected and the sensorineural decay is more pronounced on the high frequencies. The subjective hearing symptoms and overall sound perception are satisfactory.

Abstract
The aim of the study was to assess results from a large cohort of patients undergoing otosclerosis surgery with respect to the impact of intra-operative variables on post-operative hearing function and complications. We enrolled 384 patients affected by otosclerosis who were subjected to stapes surgery between 2004 and 2013 at a single institution. Surgery was performed in all cases under local anaesthesia, using a manual perforator and/or microdrill. Teflon-piston prosthesis was used in all patients. Audiological data obtained preoperatively and at last follow-up examination (minimum 12 months) were compared. Statistical analysis was performed using the multiple regression model. Peripheral rim otosclerosis and diffuse otosclerosis were associated with better functional results compared to the obliterative pattern (p < 0.05). Mean post-operative Air-Bone Gap was significantly higher in the 0.4 mm, compared to 0.6 mm piston group at 0.5 kHz (p < 0.001) and 1 kHz (p < 0.02); in the stapedotomy group a statistically significant difference was found between 0.4 and 0.6 mm piston groups, in favour of the latter (p < 0.05). No differences were encountered in terms of average hearing threshold and complications. Intra-operative variables cannot be fully predictable and our data could help in stratification of the results and as a landmark for the surgeon’s decisions.

Abstract
Nowadays oral appliance therapy is recognised as an effective therapy for many patients with primary snoring and mild to moderate obstructive sleep apnoea (OSA), as well as those with more severe OSA who cannot tolerate positive airway pressure (PAP) therapies. For this reason, it is important to focus on objective criteria to indicate which subjects may benefit from treatment with a mandibular advancement device (MAD). Various anthropometric and polysomnographic predictors have been described in the literature, whereas there are still controversies about the role of drug-induced sleep endoscopy (DISE) and advancement bimanual manoeuvre as predictor factors of treatment outcome by oral device. Herein, we report our experience in treatment of mild moderate OSA by oral appliance selected by DISE. We performed a single institution, longitudinal prospective evaluation of a consecutive group of mild moderate patients with obstructive sleep apnoea syndrome who underwent DISE. During sleep endoscopy, gentle manoeuvre of mandibular advancement less than 5 mm was performed. In 30 of 65 patients (46.2%) we obtained an unsuccessful improvement of airway patency whereas in 35 of 65 patients (53.8%) the improvement was successful and patients were considered suitable for oral device application. Because 7 of 35 patients were excluded due to conditions interfering with oral appliance therapy, we finally treated 28 patients. After 3 months of treatment, we observed a significant improvement in the Epworth medium index [(7.35 ± 2.8 versus 4.1 ± 2.2 (p < 0.05)], in mean AHI [(21.4 ± 6 events per hour versus 8.85 ± 6.9 (p < 0.05)] and in mean ODI [(18.6 ± 8 events per hour to 7 ± 5.8 (p < 0.05)]. We observed that the apnoea/hypopnoea index (AHI) improved by up to 50% from baseline in 71.4% of patients selected after DISE for MAD therapy. In the current study, mandibular advancement splint therapy was successfully prescribed on the basis not only of severity of disease, as determined by the subject's initial AHI, but also by DISE findings combined with results of gentle mandibular advancement manoeuvre allowing direct view of the effects of mandibular protrusion on breathing spaces in obstruction sites, and showing good optimisation of selection of patients for oral device treatment.

Abstract
OBJECTIVES To investigate in Parkinson's disease-affected patients a correlation between hyposmia and gastrointestinal dysfunction and their possible identical etiopathogenesis. DESIGN Retrospective cohort study. SETTING ENT and neurology departments (Gemelli Hospital, Rome, Italy). PARTICIPANTS A total of 78 patients with diagnosis of PD according to the UK Brain Bank criteria. INCLUSION CRITERIA informed consent and olfactory testing executed; exclusion criteria: signs of dementia according to the DSM-IV criteria; Mini Mental State Examination score ≤26; head trauma; central neurological disorders, nasal or systemic diseases potentially affecting olfactory function. Motor condition was assessed by means of Hoehn and Yahr staging and by section III of the Unified PD Rating Scale, performed off and on medications. MAIN OUTCOME MEASURES The patients underwent olfactory evaluation (TDI score), after rhinomanometry with nasal decongestion. A total of 25 non-motor symptoms were evaluated through an interview. RESULTS Olfactory dysfunction was objectively found in 91.0% of patients, a percentage higher than the subjective hyposmia reported (55.1%) P = 0.0001. Seven patients (9.0%) were normosmic, 49 (62.8%) hyposmic and 22 (28.2%) anosmic. Subjective hyposmia, constipation, bloating and dyspepsia differed across groups, being higher in anosmic and hyposmic ones than in the normosmic group. P value was ≤0.05 for each symptom. Despite the original results, this study has the limitation of being based on subjective ratings by a relatively limited group of patients. CONCLUSIONS Hyposmia and gastrointestinal symptoms are correlated, and this would support a possible common origin; the CNS could be reached through two different pathways, both starting in the peripheral nervous system.

Abstract
Platinum compounds constitute the standard treatment for solid tumors in pediatric oncology. The purpose of this study is to assess the impact of platinum compounds in the development of ototoxicity in children following chemotherapy. This study included 160 patients treated with cisplatin and carboplatin for malignant solid diseases from 2007 to 2014. Their audiograms were classified according to the Boston SIOP ototoxicity scale. Twenty-five percent of the children treated with platinum compounds developed ototoxicity. The incidence of ototoxicity was correlated with the type of platinum derivative (i.e. cisplatin vs. carboplatin), coadministration of both drugs and concomitant cranial radiotherapy, but not with sex and age. Cumulative dose was correlated only with the cisplatin administration. Nine patients (8.6%) showed further progression of hearing impairment after the end of chemotherapy. The low rate of ototoxicity suggests the pivotal role of auditory monitoring in children treated with platinum compounds in order to be able to identify hearing loss at an early stage and to provide, jointly with pediatric oncologists, strategies to reduce further progression of cochlear toxicity.

Abstract
Over the last 20 years, the number of stapes operations performed has decreased steadily. This inadequate exposure to stapes surgery poses problems for both trainees and trainers. We retrospectively reviewed the outcomes of stapedotomy performed by a young physician at the ENT Clinic of the "A. Gemelli" Hospital of Rome. We used the technique of "one-shot" CO2 Laser stapedotomy using a titanium-Teflon piston. For data analysis, we considered the audiograms obtained 24 hours preoperatively and at the last follow-up examination (mean 45 months). Air conduction (AC) and bone conduction (BC) PTA were calculated for 0.25, 0.5, 1, 2 and 4 kHz thresholds. Air bone gap (ABG) were obtained from ACPTA and BCPTA. Postoperative hearing gain was calculated from the ABG before the operation minus the ABG at late follow-up examination. Analysis of outcomes did not show a clear endpoint for the learning curve; complete closure of the ABG was obtained in a large number of patients at the beginning followed by patients who showed a higher ABG. Fortunately, we did not observed any "dead ear". The study supports a learning curve in stapes surgery, but the results can vary widely among surgeries with excellent results followed by others that are not fully satisfactory. Stapes surgery should not be one of the first ear surgeries performed by a young otologist due to the functional outcome expected by patients and the lack of necessary surgical skills.

Abstract
The use of "one-shot" CO2 laser technique for a primary small-fenestra stapedotomy is well established, but few papers report the long-term functional results. We retrospectively reviewed medical records of 198 patients, treated for otosclerosis from January 2008 to December 2011, at the Department of Head and Neck Surgery, Catholic University of Rome. Statistical comparison between audiological thresholds obtained 24 h preoperatively, at early (4 weeks) and late postoperative examinations (mean time 45 months), was performed. Comparison of preoperative vs both early and late postoperative ACPTA showed a statistically significant difference (respectively 55 vs 33 and 31 dB; p < 0.001). No statistical difference was observed between preoperative, early and late postoperative BCPTA (respectively 23 vs 23 and 22 dB; p > 0.05). Both early and late postoperative ABG improved significantly compared to the preoperative one (respectively 10 and 9 vs 32 dB; p < 0.001). No statistical difference was found in comparison of early vs late postoperative ACPTA (respectively 33 vs 31 dB; p > 0.05), early vs late postoperative ABG (respectively 10 vs 9 dB; p > 0.05) and early vs late ABG gain (respectively 22 vs 23 dB; p > 0.05). No subjects developed postoperative complications requiring revision surgery or late deterioration of hearing threshold. The analysis of our data suggests that "one-shot" CO2 laser stapedotomy is an effective and safe procedure: it allows a rapid stapedotomy without damages for the inner ear and optimal functional results that remain stable during the years.

Abstract
Cholesteatoma is a destructive lesion involving the temporal bone, which may induce severe complications due to its expansion and erosion of adjacent structures. Bacterial biofilm plays a crucial role in the pathogenesis of many otolaryngologic inflammatory/infectious chronic diseases. In this pilot study, we investigated, by means of cultural examination and with scanning electron microscope, the presence of bacterial biofilm in a series of samples from the epitympanic and mastoid region in patients affected by cholesteatoma and from the promontory region in patients with healthy mucosa who were undergoing to stapes surgery. The preliminary data support the association between biofilm and cholesteatoma (81.3% of the cases) and allow us to hypothesize that keratinized matrix of cholesteatoma may represent the ideal substrate for biofilm colonization and survival; this finding is consistent with the clinical course of aural cholesteatoma, characterized by recurrent exacerbations and recalcitrant course.

Abstract
BACKGROUND The aim of the present study was to measure levels of granulocyte-macrophage colony-stimulating factor (GM-CSF) in nasal lavage of patients affected by chronic eosinophilic sinonasal inflammation to clarify the relationship with eosinophilic tissue infiltration and clinical features. METHODS Between November 2012 and June 2013, we selected 70 patients with chronic eosinophilic inflammation (average age 41.8 years) who were classified into the following groups: persistent allergic rhinitis (group 1), noninfectious non-allergic rhinitis with eosinophilia syndrome (group 2) and chronic rhinosinusitis with polyps (group 3). Finally, we enrolled 20 healthy subjects as controls (group 4). All patients underwent symptoms score questionnaire based on a visual analogue scale, nasal endoscopy and/or computed tomography (CT) scan, and allergy testing. Nasal cytology by scraping of the mucosa and GM-CSF assays in nasal lavage were performed in all subjects. RESULTS Detectable levels of GM-CSF were found in 34 of 70 (48.57%) patients, with an average concentration of 2.67 ± 0.8 pg/mL, whereas in controls only 1 of 20 individuals showed detectable GM-CSF levels. Eosinophil infiltration was significantly higher in patients with detectable GM-CSF compared to those with undetectable levels (49.4% vs 39.2%, respectively; p < 0.05). Furthermore, significant weakly-moderate correlation was found between GM-CSF levels and percentage of eosinophil infiltration in tissue (p < 0.05). Correlation between symptom scores and GM-CSF levels was significant only in group 2, which showed higher average concentrations of GM-CSF compared to groups 1 and 3 (2.9 pg/mL vs 1.6 pg/mL and 1.8 pg/mL, respectively; p < 0.05). CONCLUSION Our data confirm that GM-CSF is more frequently detectable in nasal lavages of patients affected by chronic sinonasal eosinophilic inflammation than in controls. Statistical analyses revealed a significant weakly-moderate correlation between GM-CSF levels in nasal lavage of all patients and percentage of eosinophil infiltration of nasal mucosa.

Abstract
OBJECTIVE To investigate the role of inflammation in non-allergic rhinitis (NAR) patients in a large series to establish the prevalence of different NAR-subtypes, clinical features and the role of nasal cytology in the diagnostic algorithm. METHODOLOGY Patients were selected out of 3650 individuals who spontaneously presented at our institution. We consecutively enrolled 519 NAR-patients in an analytical cross-sectional study between November 2007 and June 2013 (level of evidence: 3b). All patients underwent rhinological evaluation including symptoms questionnaire, endoscopy, CT scan, allergy tests and nasal cytology. RESULTS The inflammatory cell infiltrate affects the severity of symptoms differently, allowing for identification of different phenotypes of NAR. We distinguished two groups: “NAR without inflammation”(NAR-) and “NAR with inflammation”(NAR+), in addition to different NAR-subtypes with inflammation. A significant difference was observed in terms of clinical symptoms and association with comorbidities (previously diagnosed asthma and aspirin intolerance) between NAR–, NAR+ and between different NAR+ subtypes. CONCLUSION Our data suggest that NAR- and NAR with neutrophils behave similarly, showing lower symptom score values and a lower risk of association with comorbidities compared to NAR with eosinophils and mast cells (singularly or mixed). In our belief it is very important to establish the presence and type of inflammation in non-allergic rhinitis patients and nasal cytology is a very useful test in correct differential diagnosis.

Abstract
BACKGROUND The aim of the present study was to measure eotaxin-3 (CCL26) and eotaxin-2 (CCL24) in nasal lavage fluid of patients with different forms of chronic sinonasal eosinophilic inflammation to evaluate their role in the pathophysiology of nasal hypereosinophilia. METHODS The study was an analytic cross-section study, level of evidence 3b. Patients (n = 80) with nasal hypereosinophilia were randomly recruited and grouped in the following categories: persistent allergic rhinitis (AR) (n = 25), nonallergic rhinitis with eosinophilia syndrome (NARES) (n = 30), and chronic rhinosinusitis with polyps (CRSwNP) (n = 25). Non-rhinitic volunteers (n = 20) were recruited as controls. CCL24 and CCL26 concentrations were measured by enzyme-linked immunosorbent assay (ELISA) Quantikine Human Immunoassays (R&D Systems, Minneapolis, MN) in nasal lavage fluids. Differential cell counts were performed by microscopic cytological examination of nasal tissue scraped from the inferior turbinate. RESULTS Mean CCL26 levels were significantly higher (p < 0.05) in AR and in NARES (132.0 pg/mL and 187.63 pg/mL, respectively) than in the control group (13.5 pg/mL); in patients with CRSwNP, CCL26 values were increased compared to controls even though the difference was not statistically significant (58.9 pg/mL vs 16.5 pg/mL). Mean CCL24 levels measured in AR, NARES, and CRSwNP were significantly increased (p < 0.05) compared to controls (96.7 pg/mL, 135.4 pg/mL, and 107.0 pg/mL, respectively, vs 32.2 pg/mL). Moreover, we observed a significant correlation between CCL24 and CCL26 levels, evaluating them intraindividually by Spearman's rank correlation test. Finally, a significant correlation was found between CCL24 and CCL26 levels and the percentage of eosinophilic infiltration of nasal mucosa. CONCLUSION Our data suggest that CCL26 and CCL24 are likely involved in the pathogenesis of chronic nasal hypereosinophilia, with a complex cooperation and different involvement of the various members of eotaxin family. Further studies are necessary to better understand the actual physiopathologic mechanism, possible clinical relevance, and therapeutic implications.

Abstract
Objective: Assess and compare the functional results obtained by means of multiple-shot Erbium: yttrium-aluminum-garnet (Er:YAG) laser to those obtained using “one-shot” CO2 laser stapedotomy in patients affected by otosclerosis. Study Design: A retrospective case review was performed. Setting: The study was conducted at the Catholic University of Rome. Method: We compared the results obtained in 2 series. From January 2004 to January 2006, a Er:YAG laser stapedotomy was performed on 101 patients. From January 2008 to December 2009, 110 subjects underwent “one-shot” CO2 laser stapedotomies for otosclerosis. Pure-tonal audiometric test was performed preoperatively and after surgery during the follow-up. Results: In both groups the closure of air-bone gap began in the early postoperative period and continued to improve through the late postoperative period. Bone-conduction hearing thresholds were stable even in the early postoperative follow-up and remained stable trough the course of the study. Conclusion: Our findings confirm that laser stapedotomy is a safe and effective surgery. Respect to Er:YAG laser, the improvement of the CO2 laser and the development of the “one-shot” technique justify a larger use of this equipment that allows one to achieve the stapedotomy with less manipulations and a reduced acoustic trauma.

Abstract
Gentamicin, acting as an iron chelator, activates membrane lipid peroxidation (MPL) and induces free radical formation, as observed in vitro and in vivo. Antioxidants, such as alpha-tocopherol, are able to suppress MLP, thus attenuating tissue damage. The present study was designed to investigate the possible protective effects of alpha-tocopherol on gentamicin ototoxicity. The study was carried out on albino guinea pigs (250-350 g). The animals were divided into four groups: group A (n = 4), injected with corn oil daily at a dose of 100 mg/kg body weight intramuscularly (IM); group B (n = 10), treated with corn oil at a dose of 100 mg/kg body weight and gentamicin base at a dose of 100 mg/kg body weight (IM); group C (n = 10). treated with gentamicin alone at a dose of 100 mg/kg body weight (IM); and group D (n = 10), treated with gentamicin at the same dose plus alpha-tocopherol acetate at dose of 100 mg/kg body weight (IM). Electrocochleographic recordings were made from an implanted round-window electrode. All animals were treated for 14 days. The compound action potentials (CAPs) were measured at 2-16 kHz at days 0, 10, 14 and 18 after treatment. Changes in cochlear function were characterized as CAP threshold shifts. Morphological changes were analysed by scanning electron microscopy. Gentamicin induced progressive high-frequency hearing loss of 50-60 dB SPL. alpha-Tocopherol co-therapy slowed the progression of hearing loss. The significant loss of outer hair cells (OHCs) in the cochlear basal turn in gentamicin-treated animals was not observed in the cochleas of animals protected with alpha-tocopherol. This study supports the hypothesis that alpha-tocopherol interferes with gentamicin-induced free radical formation, and suggests that this drug may be useful in protecting OHC function from aminoglycoside ototoxicity, thus reducing hearing loss.

Abstract
The purpose of this study was to evaluate cisplatin-induced ototoxicity and the protective effects of tiopronin. Twenty-four adult Wistar rats served as subjects and were divided into three groups. Eight rats receiving only saline (group A) were used as controls. Eight rats received cisplatin (2 mg/kg) injections (group B) and eight rats received cisplatin and tiopronin (300 mg/kg) (group C) for 8 consecutive days. Both ears of all animals were tested by DPOAE before treatment and on the 4th and 9th days. Seventy-two hours after the final recording session, all animals were killed, and the left cochleas were prepared for electron microscopy and analysed. DPOAE responses were significantly reduced in group B compared to controls (p<0.05). When tiopronin was added, DPOAE responses were significantly increased compared to those obtained with the administration of cisplatin alone (p<0.05). The cochleogram showed that tiopronin had a significant protective effect in the basal half and in the lower half of the middle turn. We conclude that tiopronin, a drug effective in protecting against cisplatin nephrotoxicity, is also effective in protecting against cisplatin ototoxicity.

Abstract
Increasing evidence suggests the involvement of oxidative stress in noise-induced hearing loss. The present study analysed, in an animal experimental model, the time course of the pathogenic mechanisms of noise-induced cochlear damage and the efficacy of the antioxidant drug N-acetylcysteine in reducing noise ototoxicity. Animals were divided into two groups, exposed to noise one treated with N-acetylcysteine for 3 days and one (the control group) with saline. Acoustic trauma was induced by a continuous pure tone of 6 kHz, at 120 dB SPL for 30 minutes. Electrocochleographic recordings were made from an implanted round window electrode and the compound action potentials were measured daily at 2-16 kHz for 7 days. Morphological changes were analysed by scanning electron microscopy. The acoustic threshold measured 1 hour after acoustic trauma was elevated in the control group to 70-90 dB in the higher frequencies of the compound action potential audiogram, with a maximum threshold elevation ranging between 12 and 16 kHz. During the first 24 h, following acoustic trauma, there was a partial recovery of compound action potential thresholds of about 20 dB to reach a final threshold elevation of about 50-70 dB; there was no further improvement over the remaining experimental week. Animals treated with N-acetylcysteine showed a similar temporary threshold shift but a clear improvement in the recovery of compound action potential thresholds, with significantly reduced permanent threshold shift and hair cell loss. These data suggest that N-acetylcysteine is able to attenuate the toxic effect of acoustic trauma and could represent an interesting molecule for preventing inner ear injuries.

Abstract
Aim of the present report is to discuss and underline the diagnostic algorithm and the surgical approach to giant parotid pleomorphic adenomas arising in the deep lobe and growing in the parapharyngeal space. Three cases are described and a review is made of the international literature concerning giant deep lobe parotid gland pleomorphic adenoma. Diagnosis was based on imaging, computed tomography scan and magnetic resonance imaging and upon cytology, by means of fine needle aspiration biopsy. The surgical approach varied according to the location of the tumour. All patients were discharged without complications and no cases of permanent facial nerve palsy were observed. An exhaustive pre-operative diagnostic algorithm is required before approaching this lesion. Fine needle aspiration biopsy is, in our opinion, mandatory to avoid histological surprises. The surgical approach should provide excellent visibility with wide surgical exposure to secure local neurovascular structures.

Abstract
Fabry disease is an inborn error of metabolism due to deficient activity of the lysosomal enzyme alpha-galactosidase A. The enzyme defect leads to the systemic accumulation of neutral glycosphingolipids in tissues. Otological manifestations consist of hearing loss and mild vestibular disorders. In this report we describe a family of five members affected by Fabry disease with four subjects showing inner ear involvement.

Abstract
The aim of this study was to evaluate the hearing results of ossiculoplasty in canal wall down tympanoplasty in one stage middle-ear cholesteatoma surgery.We carried out a retrospective review of a consecutive series of 142 cases which had undergone type two or three canal wall down tympanoplasty with ossicular reconstruction, between January 1995 and December 2002, due to chronic otitis media with cholesteatoma.Pre-operative audiometric testing revealed a mean air conduction pure tone average (PTA) of 50.97 dB and a mean bone conduction PTA of 22.14 dB. The mean post-operative result for air conduction PTA was 37.62 and for bone conduction PTA was 23.37 dB. The mean pre- and post-operative air–bone gaps (ABGs) were 28.83 and 13.94 dB, respectively, with a gain of 14.89 dB. Almost 62.67 per cent of patients closed their ABGs to within 20 dB.Our functional results are comparable with those of other authors. In the present study, we show that hearing improvement is possible following cholesteatoma surgery with canal wall down tympanoplasty and ossicular chain reconstruction.

Abstract
Idebenone is a synthetic analogue of coenzyme Q10 with antioxidant properties. The present study investigated the antioxidant activity of idebenone in the rescue of acoustic trauma. Noise-induced hearing loss was induced by exposing guinea pigs to a continuous pure tone and idebenone was injected intraperitoneally 1 h before noise exposure and once daily for 3 days. Guinea pigs treated with idebenone showed significantly smaller auditory threshold shifts than unprotected control animals. Missing and apoptotic cells were identified with scanning electron microscopy and terminal deoxynucleotidyl transferase-mediated dUTP nick end labelling assay. Protected animals presented a lesser extent of both apoptotic activation and hair cell loss in the organ of Corti. Our results suggest an antioxidant function of idebenone in protection from noise-induced hearing loss and provide a rationale for exploring therapeutic strategies in humans.

Abstract
Noise-induced hearing loss has been associated with alterations in cochlear blood flow. Our study analyzed the expression of Vascular Endothelial Growth Factor (VEGF) and its functional receptors, Flt-1 and Flk-1, in the cochlear structures of noise-exposed and unexposed guinea pigs. VEGF is a prototypical angiogenic agent, with multiple functions on vascular biology, ranging from vascular permeability to endothelial cell migration, proliferation, differentiation, and survival. Acoustic trauma was induced by a continuous pure tone of 6 kHz, at 120 dB SPL for 30 min. Auditory function was evaluated by electrocochleographic recordings at 2-20 kHz for 7 days. Noise-induced cochlear morphological changes were studied by immunohistochemistry and scanning electron microscopy. The expression of VEGF and its receptors was examined by immunohistochemistry and western blotting analysis. The hearing threshold shift reached a level of 60 dB SPL on day 1 after trauma and underwent a partial recovery over time, reaching a value of about 20 dB SPL on day 7. Outer hair cell loss was more prominent in the area located 14-16 mm from the apex. Increased cochlear VEGF expression was observed in noise-exposed animals, in particular at the level of stria vascularis, spiral ligament, and spiral ganglion cells. No changes were observed in the expression of VEGF-receptors. Our data suggest a role for VEGF in the regulation of the vascular network in the inner ear after acoustic trauma and during auditory recovery, with potentially important clinical and therapeutic implications.

Abstract
Cerebrospinal fluid rhinorrhea occurs as a result of abnormal communication between the subarachnoid space and the pneumatized portion of the skull base, the paranasal sinuses and the middle ear. Conservative measures may be sufficient in the management of cerebrospinal fluid rhinorrhea, but, in some cases, surgical treatment may be required. Transnasal endoscopic techniques are constantly being used in preference to the intra- and extracranial approaches. Recently, image guidance systems have been adopted in neurosurgery, skull base and paranasal sinus surgery. The present report refers to 4 cases of nasal cerebrospinal fluid rhinorrhea leak successfully treated with a transnasal endoscopic approach using various techniques and materials to close the bone defect, in 2 of which, the navigation system (Stealth Station Treon ENT Image Guidance System with Landmark X, Software, Medtronic, XOMED, Jacksonville, FL, USA) was also used. In all cases, correct localization and repair of the leak was achieved and no major complications occurred. Following a review of the literature, the Authors conclude that, at present, transnasal endoscopic repair of cerebrospinal fluid rhinorrhea is the surgical treatment of choice when the techniques and materials are correctly used. Furthermore, preliminary findings indicate that it is possible to make routine use of the navigation systems and that this technology may be usefully employed, above all, in the management of cerebrospinal fluid leaks.

Abstract
OBJECTIVE To investigate the possible protective effects of alpha-tocopherol and tiopronin against cisplatin-induced cochlear damage. Cisplatin ototoxicity and nephrotoxicity seem to result from the inhibition of cochlear antioxidant defences, causing an increase in the amount of reactive oxygen species. Antioxidants, such as alpha-tocopherol and tiopronin, are able to suppress lipid peroxidation, thus attenuating tissue damage. MATERIAL AND METHODS Hartley albino guinea pigs were used. The animals were treated for 7 consecutive days with either (I) cisplatin alone, (II) cisplatin+alpha-tocopherol acetate, (III) cisplatin+tiopronin, (IV) cisplatin+alpha-tocopherol acetate+tiopronin, (V) alpha-tocopherol acetate alone or (VI) tiopronin alone. Changes in cochlear function were characterized by means of compound action potential threshold shifts. After the functional testing, tympanic bullae were removed and processed for morphological examination of the sensorineural epithelium. Renal function was evaluated by measuring serum blood urea nitrogen and creatinine levels. RESULTS Cisplatin induced progressive high-frequency hearing loss of 40-50 dB SPL. Alpha-tocopherol and tiopronin co-therapy significantly slowed the progression of hearing loss. Treatment with alpha-tocopherol acetate or tiopronin alone was less effective. Morphological observations showed an important loss of outer hair cells and degeneration of the organ of Corti in the basal and middle turns. Injection of both alpha-tocopherol and tiopronin reduced cochlear outer hair cell loss more than treatment with a single drug. Beneficial effects of alpha-tocopherol and tiopronin on cisplatin-induced nephrotoxicity were observed. CONCLUSION This study supports the hypothesis that alpha-tocopherol and tiopronin interfere with cisplatin-induced damage, and suggests that concurrent treatment with the two drugs can be useful in protecting against hearing loss.

Abstract
A number of studies have shown that cisplatin and gentamicin ototoxic effects may result from free radical-mediated damage due to the reduction of antioxidant substances and an increased lipid peroxidation. The authors summarize the results obtained evaluating the auditory and vestibular functions and the inner ear hair cell morphology and survival after administration of antioxidant agents against cisplatin and gentamicin. In the first experiment, albino guinea pigs were treated with gentamicin (100 mg/kg per day, i.m.) alone or gentamicin (100 mg/kg per day, i.m.) plus alpha-tocopherol (100 mg/kg per day, i.m.) for 2 weeks. In a second experiment, albino guinea pigs were injected with cisplatin (2.5 mg/kg per day) or cisplatin (2.5 mg/kg per day) plus tiopronin (300 mg/kg) for 6 days. Electrocochleographic recordings were made from an implanted round window electrode. In all experiments compound action potentials (CAPs) were measured at 2-16 kHz. Changes in cochlear function were characterized as CAP threshold shifts. To evaluate vestibular function, the animals underwent sinusoidal oscillations in the dark about their vertical and longitudinal axes to evoke horizontal and vertical vestibulo-ocular reflexes (VOR). Frequency stimulation parameters ranged from 0.02 to 0.4 Hz and peak-to-peak amplitude was 20 degrees. Morphological changes were analysed by light microscopy and scanning electron microscopy. Both hearing loss and vestibular dysfunction induced by gentamicin were significantly attenuated by alpha-tocopherol. However, tiopronin co-therapy slowed the progression of hearing loss in cisplatin-treated animals and significantly attenuated the final threshold shifts. Cisplatin had little effect on the hair cells of cristae ampullares and maculae. Vestibular function was completely preserved in tiopronin co-treated animals. In conclusion, antioxidants such as alpha-tocopherol or tiopronin interfere with gentamicin and cisplatin damage and this suggests that they may be useful in preventing oto-vestibulotoxicity. Therefore, it is important to develop protective strategies that permit the avoidance of the toxic side effects of these drugs without interfering with their therapeutic effects.

Abstract
The authors report a clinical case of gas gangrene in a rare anatomic location in a 79-year-old woman, admitted because 3 days earlier she had developed a painful swelling with erythematous cutis in her right iliac fossa and suffered from a seriously increasing fever. The physical examination showed a large area of gas gangrene. In accordance with international literature, excellent results have been obtained by adopting an early multiple therapy (including surgical debridement, intensive therapy, antibiotic treatment and hyperbaric oxygen treatment).

Abstract
AIM This study aimed to evaluate audiological and vestibular involvement in Fabry disease and the early effects of enzyme replacement therapy with human alpha-galactosidase A. METHODS Fourteen patients (10 males, 4 females) aged 14-57 years were studied. Each patient underwent a clinical (history of otological and vestibular aspects, otoscopy) and instrumental (pure tone and speech audiometry, impedance, auditory brainstem response and oto-acoustic emission recordings, vestibular caloric tests, electronystagmography during acceleratory stimulation, dynamic posturography) evaluation before starting enzyme replacement therapy. RESULTS Fifty per cent of patients complained of hearing symptoms (hearing loss, tinnitus, ear fullness). Subjective hearing loss was present in six cases and in three cases it was the first reported symptom of Fabry disease. In six of the seven cases the onset and/or progression of hearing symptoms were sudden. Vertigo or dizziness was reported by four patients and in two cases was associated with hearing symptoms. Audiological evaluation showed sensorineural hearing loss in eight patients (5 males, 3 females). Hearing loss was unilateral in six cases and bilateral in the remaining two cases. The hearing loss (HL) ranged from 30 to 80 dB HL (mean, 43 dB HL) and the lesion was always cochlear. Vestibular examination showed abnormalities in four patients (bilateral weak/abolished response in three cases, side prevalence in one case), which were not related to either the audiological results or the history of vertigo/dizziness. CONCLUSION Involvement of the inner ear is common in men and women with Fabry disease. We found a high incidence of cochlear hearing loss, which was typically unilateral and showed onset and/or progression by sudden episodes. Vascular or hydropic mechanisms could be hypothesized to explain audiological findings. Vestibular involvement had a lower incidence and showed a different pattern, thus suggesting that several pathophysiological mechanisms could play a role in determining inner ear damage in Fabry disease. Our preliminary results show that enzyme replacement therapy may stabilize hearing function; however, further follow-up is required.

Abstract
Laryngopharyngeal reflux is now of major interest as an aetiologic factor in chronic inflammatory and neoplastic lesions of upper digestive tract. However, reports in the literature refer only to the irritating action of the acid component of reflux, while possible damaging action of other reflux components remains unknown. Aim of this study was to verify the hypothesis that alkaline-bile reflux could also be involved in onset of inflammatory, precancerous and neoplastic laryngeal lesions. A total of 40 consecutive gastrectomized patients coming to our Clinic from Gastroenterology Outpatient Unit for an anamnestic and clinical evaluation with videolaryngoscopy of upper digestive airways, entered the study. All presented bile or alkaline reflux as a direct consequence of gastroduodenal anastomosis (Billroth I) and gastrojejunal anastomosis (Billroth II) performed over a time span > 20 years. Oesophagogastroduodenoscopy revealed the presence of bile in the residual gastric cavity in all operated patients objectively confirming duodenogastric reflux. Examination of data showed that 3 patients (7.5%) had undergone CO2 laser cordectomy in the 3 years prior to the study for squamous cell laryngeal carcinoma, 3 patients (7.5%) had leukoplakia, 8 (20%) vocal cord chronic oedema with signs of chronic diffuse laryngitis, 6 (15%) posterior laryngitis, 8 (20%) interarytenoid oedema while only 12 (30%) showed no ENT lesions. Statistical analysis revealed a significant correlation between incidence of inflammatory and neoplastic laryngeal lesions and type of surgery (Billroth II and total gastrectomy) with respect to other types of gastric resection. There was also a significant increase in presence and severity of laryngopharyngeal lesions in relation to time elapsed after surgery. These results, although preliminary, seem to confirm that some components of reflux (duodenal content), other than the acid component, play a damaging role involved in the onset of multiple clinical signs and symptoms of laryngopharyngeal reflux disease. It is concluded that systematic use of bile measurement, together with 24-hour pH monitoring, is advisable in subjects with clinical signs and symptoms of laryngopharyngeal reflux, but unresponsive to classic medical treatment, and in gastrectomized patients in order to confirm, on larger series, this fascinating aetiopathogenetic hypothesis.

Abstract
Pre-operative fine-needle aspiration biopsy findings have been compared with those of post-operative histopathology in 146 patients with parotid masses. Post-operative histology showed 124 benign and 22 malignant lesions: pre-operative fine-needle aspiration biopsy correctly identified 118/124 (95.1%) benign masses with an accurate classification of the tumour in 111/118 cases (94%). Fine-needle aspiration biopsy identified malignancy in 12/22 cases (>50%). In the remaining 7 cases (six benign lesions and one malignant), cytology was not diagnostic. There were no false positive cases. In the present study, the accuracy, sensitivity and specificity of cytologic findings were, respectively, 94%, 57.2% and 100%. The accuracy of fine-needle aspiration biopsy was seen to be higher in benign than in malignant lesions. Fine-needle aspiration biopsy represents a first choice diagnostic tool for the study of palpable head and neck masses excluding abscesses and vascular neoplasms. However, for a correct diagnosis, great skill is required and cytology does not always reach the sensitivity and specificity of post-operative histology. Therefore, in the presence of a palpable head and neck mass, resistant to medical treatment, surgery is still strongly indicated and cytology is very useful in planning the surgical approach.

Abstract
The aim of the present study was to investigate both vestibular and cochlear cisplatin toxicity. Twelve albino guinea pigs were divided into an experimental (n=8) and a control saline group (n=4) and were treated with cisplatin at a daily dose of 2.5 mg/kg for 6 consecutive days. Vestibular dysfunction was evaluated by computing the gain of the vestibular ocular reflex (VOR) evoked by stimulation in the horizontal (HVOR) and vertical (VVOR) planes. Changes in cochlear function were characterised as compound action potential threshold shifts. After the functional testing, tympanic bullae were removed and processed for morphological examination of the sensorineural epithelium. The onset of vestibular functional impairment was observed on the third day, although the VOR gain decrease was not significant. The impairment of the vestibular function progressed until the sixth day becoming statistically significant particularly at VVOR mid frequencies of stimulation. At these frequencies both macula and crista ampullaris functions are involved. Concomitantly a progressive auditory threshold shift was observed at all stimulus frequencies. The decline of the auditory function was statistically significant from the third day of treatment and it was more evident at high frequencies. Morphological observations showed a massive loss of outer hair cells and a degeneration of the organ of Corti in the basal/middle turns and only a slight loss of hair cells of the cristae ampullares and maculae. In conclusion, functional and morphological data provide evidence that the toxic effect of cisplatin is more pronounced in the organ of Corti than in the vestibular epithelium.

Abstract
OBJECTIVE Free radicals are involved in gentamicin ototoxicity and vestibular dysfunction and it has been demonstrated that free radical scavengers, such as alpha-tocopherol, are able to inactive free radicals, attenuating tissue damage This study was designed to investigate the possible protective effects of alpha-tocopherol against gentamicin-induced oto-vestibulo toxicity. MATERIAL AND METHODS Adult albino guinea pigs were divided into four groups and were treated for 2 weeks as follows: Group A, controls; Group B, gentamicin plus corn oil; Group C, gentamicin only; and Group D, gentamicin plus alpha-tocopherol. To evaluate vestibular function, the animals underwent sinusoidal oscillations in the dark about their vertical and longitudinal axes to evoke horizontal and vertical vestibulo-ocular reflexes (VORs), respectively. Electrocochleographic recordings were performed using an implanted round window electrode. The compound action potentials (CAPs) at 2, 4, 8 and 16 kHz were measured every 5 days Morphological changes were analysed by means of scanning electron microscopy. RESULTS Gentamicin induced a consistent reduction in VOR responses and a progressive high-frequency hearing loss of 50-60 dB sound pressure level. Alpha-Tocopherol co-therapy slowed the progression of hearing loss and significantly attenuated the final threshold shifts The impairment of vestibular function was reduced, as evidenced by an increased VOR gain. The massive loss of outer hair cells in the cochlear basal turn and of cristae ampullaris stereocilia in gentamicin-treated animals was not observed in the cochlea of animals protected with alpha-tocopherol. CONCLUSION This study supports the hypothesis that alpha-tocopherol interferes with gentamicin-induced free radical formation, and suggests that this drug may be useful in preventing aminoglycoside oto-vestibulo toxicity.
