Abstract Background Stapedotomy is being performed endoscopically for otosclerosis in Sudan since 2011 with increasing number of patients. This prospective hospital-based study from Nov 2016 to Nov 2020 states the clinic-demographic features of otosclerosis; it describes this surgical technique and hearing outcome following endoscopic stapedotomy. Results Total number included in the study was 91 patients. Females were 48, and males were 43 with a female to male ratio of 1.1:1. Age ranged from 19 years to 52 with a mean age of 30.6± 7 SD years. The main symptom was decreased hearing in all patients (100%); in 82 patients (90%), it was bilateral, followed by tinnitus in 80 patients (88%) while two patients (2.2%) had vertigo. Family history was stated by 2 patients (2.2%) only. Audiological assessment by pure tone audiogram (PTA) for each ear (total of 182) revealed that conductive hearing loss (CHL) is the commonest type of hearing loss in 148 ears (81.3%), mixed type in 30 ears (16.5%), while 4 ears (2.2%) were normal. Endoscopic stapedotomy was performed for 74 patients; this technique was safe; few complications were managed successfully: one gusher and one revision, with no facial nerve injury. Majority of complications happened during the first year. Mean air bone gap (ABG) gain was 23.3± 7.2 dB, air conduction (AC) gain was 18.3 ± 8 dB, and Carhart notch disappeared in 79.5%. Conclusions Endoscopic stapedotomy is a safe and effective procedure with a steep learning curve and a satisfactory hearing outcome. The air bone gap (ABG) gain was comparable to international studies.

Chronic suppurative otitis media is one of the common otological conditions in India for which patients seek advice from an otorhinolaryngologist. Chronic suppurative otitis media is recurrent and progressive disease which is characterized with tympanic membrane perforation and suppurative discharge. Pure tone audiometry is the most common test used to evaluate auditory sensitivity. Since hearing loss is a common complication of chronic suppurative otitis media, we designed this study to evaluate preoperative pure tone audiometry findings in patients with chronic suppurative otitis media and its correlation with the intra-operative findings. <strong>Aims and Objectives:</strong> 1] To assess the intra-operative findings in patients with chronic suppurative otitis media. 2] To evaluate the correlation between the preoperative pure tone audiometry findings and intra-operative findings in patients with chronic suppurative otitis media. 3] To assess the type of hearing loss and degree of hearing loss in patients with chronic suppurative otitis media. <strong>Materials and Methods:</strong> This is an Observational study carried over a period of 3 years from August 2011 to August 2013. Total number of patients included in this study was 100. <strong>Result:</strong> Out of 100 patients studied 69 % of patients had Tubo-Tympanic type of CSOM, 31 % of patients had Attico-antral type of CSOM. In patients of Safe CSOM; Central perforation was seen in maximum cases 46.4 %, anterior central perforations was seen in 8.7 % cases, posterior central perforations seen in 20.2 % cases, and subtotal perforations seen in 24.63 % cases. In patients of Unsafe CSOM posterosuperior cholesteatoma was seen in maximum cases 67.74 %, and attic cholesteatoma was seen in 32.2 % cases. In safe CSOM patients all ossicles were intact and mobile whereas in unsafe CSOM patients only 4 patients had intact ossicular chain, while maximum patients had ossicular defect. <strong>Conclusion:</strong> Hearing loss depends on size of perforation. Hearing loss increases as the size of perforation increases. Average air conduction threshold and air bone gap did not differ significantly between various groups of ossicular defect. This shows us that neither air conduction nor air bone gap are reliable parameters on basis of which we can predict ossicular status preoperatively.

AbstractFifty-six individuals with acromegaly referred for pituitary surgery were studied to determine any relationship between acromegaly and sensorineural or conductive hearing loss. Compared to a matched population control sample, no significant difference between the acromegalics and controls has been found, either for air conduction or for bone conduction. The differences between these findings and those published previously are discussed, and reasons proposed to explain the discrepancies.

AbstractIntroduction:Despite advances in imaging and other diagnostic tests, it is often impossible to establish with confidence a pre-operative diagnosis in a patient with a conductive hearing loss.Methods:We studied a series of 340 exploratory tympanotomies for conductive hearing loss carried out by a single surgeon.Results:The most common operative diagnosis was otosclerosis (n = 164, 48.2 per cent). Ossicular discontinuity was found more commonly than previously reported (n = 103, 30.3 per cent). A small but significant number of patients were found to have cholesteatoma (n = 7.2 per cent).Conclusions:This information is of value when discussing potential findings at surgery for conductive hearing loss. While otosclerosis is the commonest finding in such cases, a significant number of patients have defects of the ossicular chain.

Objectives To assess the feasibility of radiologic measurements and find out whether hearing outcome could be predicted based on computer tomography (CT) scan evaluation in patients with temporal bone fractures and suspected ossicular joint dislocation. Methods We assessed 4002 temporal bone CT scans and identified 34 patients with reported ossicular joint dislocation due to trauma. We excluded those with no proven traumatic ossicular dislocation in CT scan and patients with bilateral temporal bone fractures. We measured four parameters such as malleus-incus axis distance, malleus-incus angle at midpoints, malleus- incus axis angle and ossicular joint space. The contralateral healthy side served as its own control. Hearing outcome 1–3 months after the index visit was analyzed. We assessed diagnostic accuracy and performed a logistic regression using radiologic measurement parameters for outcome prediction of conductive hearing loss (defined as >20dB air-bone gap). Results We found excellent inter-rater agreement on the measurement of axis deviation between incus and malleus in CT scans (interclass correlation coefficient 0.81). The larger the deviation of incus and malleus axis, the higher probability of poor hearing outcome (odds ratio (OR) 2.67 per 0.1mm, p = .006). A cut-off value for the axis deviation of 0.25mm showed a sensitivity of 0.778 and a specificity of 0.94 (p < .001) for discrimination between poor and good hearing outcome in terms of conductive hearing loss. Conclusion Adequate assessment of high resolution CT scans of temporal bone in which ossicular chain dislocation had occurred after trauma was feasible. Axis deviations of the incus and the malleus were strongly predictive for poor hearing outcome in terms of air conduction 1–3 months after trauma. We propose a 3-level classification system for hearing outcome prediction based on radiologic measures.

Loudness Summation

A new non-invasive adhesive bone conduction hearing device (ABCD) has been proposed as an alternative solution for reversible bilateral conductive hearing loss in recurrent or long-lasting forms of otitis media with effusion (OME) in children that cannot undergo surgical treatment. Our aim was to assess the effectiveness of ABCD in children with OME. Twelve normal-hearing Italian-speaking volunteers, in whom a conductive hearing loss was simulated, participated in the study. The free-field average hearing threshold was determined and, to evaluate binaural hearing skills, loudness summation and the squelch effect were assessed. Five conditions were tested: (1) unaided without earplugs, (2) unaided with bilateral earplugs, (3) aided right ear with bilateral earplugs, (4) aided left ear with bilateral earplugs, and (5) bilateral aid with bilateral earplugs. Post-hoc analysis showed a significant statistical difference between plugged, unplugged, and each aided condition. The main results were a better loudness summation and a substantial improvement of the squelch effect in the bilaterally aided. Our results suggest that ABCD is a valid treatment for patients with conductive hearing loss that cannot undergo bone conduction implant surgery. It is also important to consider bilateral aids in order to deal with situations in which binaural hearing is fundamental.

ABSTRACT Introduction Radiotherapy either primary or adjuvant, is a commonly used modality of treatment in head and neck malignancies. The audiovestibular apparatus is often within the fields of radiation treatment, and hearing loss is a possible complication. This study was undertaken to assess the audiovestibular functions in patients undergoing radiation therapy for head and neck malignancies to determine the type and severity of hearing loss and vestibular dysfunction following radiation therapy. Materials and methods Fifty patients with head and neck malignancies reported to the malignant disease treatment center of INHS Asvini and received radiotherapy as a primary modality of treatment or in combination with surgery during the period May 2003 to Sep 2004 were included in this study. None of these patients had prior treatment by chemotherapy. Conclusion A significant number of patients who were subjected to radiation therapy for head and neck malignancies develop conductive hearing loss is predominant in the immediate postradiation period. Conductive hearing loss is reversible and improves with the conservative line of treatment. Sensorineural hearing loss more commonly affects the higher frequencies and is more common in older patients. Sensorineural hearing loss is more common when radiation doses exceed 60 Gy. There is no conclusive evidence of vestibular dysfunction in patients undergoing radiotherapy for head and neck cancers.

Introduction The tone-evoked auditory brainstem responses (tone-ABR) enable the differential diagnosis in the evaluation of children until 12 months of age, including those with external and/or middle ear malformations. The use of auditory stimuli with frequency specificity by air and bone conduction allows characterization of hearing profile. Objective The objective of our study was to compare the results obtained in tone-ABR by air and bone conduction in children until 12 months, with agenesis of the external auditory canal. Method The study was cross-sectional, observational, individual, and contemporary. We conducted the research with tone-ABR by air and bone conduction in the frequencies of 500 Hz and 2000 Hz in 32 children, 23 boys, from one to 12 months old, with agenesis of the external auditory canal. Results The tone-ABR thresholds were significantly elevated for air conduction in the frequencies of 500 Hz and 2000 Hz, while the thresholds of bone conduction had normal values in both ears. We found no statistically significant difference between genders and ears for most of the comparisons. Conclusion The thresholds obtained by bone conduction did not alter the thresholds in children with conductive hearing loss. However, the conductive hearing loss alter all thresholds by air conduction. The tone-ABR by bone conduction is an important tool for assessing cochlear integrity in children with agenesis of the external auditory canal under 12 months.

Abstract Introduction Mucopolysaccharidosis (MPS) is a set of rare diseases caused by deficiency of lysosomal enzymes that lead to the accumulation of glycosaminoglycans (GAG) in tissues and organs, which, in turn, is responsible for the multisystemic clinical, chronic, and progressive symptoms. Objective To describe the profile of the otorhinolaryngological clinical examination and audiology tests of patients with MPS disease. Methods The present study is a case series. The evaluation was performed, initially, in 24 patients with MPS types I, II, IIIA, IV and VI. Results The most common hearing complaint was hearing loss, which was confirmed by audiology tests in almost 100% of the patients, most of whom presented conductive hearing loss. Conclusions It is important to evaluate the complaints, physical examination, and audiology tests in patients with MPS. The otorhinolaryngologistshould be part of the group of professionals that follows these patients to better monitor their hearing and provide early hearing rehabilitation.

Objective To evaluate the characteristics of children with cleft palate associated with persistent otologic issues in the first 10 years of life. Study Design Case series with chart review. Setting Single academic center. Subjects and Methods Children born with cleft palate from 2003 to 2007 and treated by the UC Davis Cleft and Craniofacial Team between January 2003 and December 2017 were included in the study. Data from 143 patients were analyzed via Wilcoxon rank sum and Fisher exact tests for univariate analysis and logistic regression to determine adjusted odds ratios. Results The median length of follow-up was 9.9 years, and the age at last ear examination was 10.7 years. At the last evaluation, unresolved otologic issues were common, with at least 1 ear having a tympanic membrane (TM) perforation (16.1%), a tympanostomy tube (36.2%), or conductive hearing loss (23.1%). After adjusting for demographic and clinical characteristics, history of palate revision or speech surgery was associated with having a TM perforation ( P = .02). The only clinical variables associated with conductive hearing loss was the presence of a TM perforation ( P < .01) or a genetic abnormality ( P = .02). Severity of palatal clefting was not associated with specific otologic or audiologic outcomes after adjusting for other characteristics. Conclusion A large proportion of children with cleft palate have persistent otologic issues at age 10 years and would benefit from continued close monitoring well after the age when most children have normalized eustachian tube function. Prolonged otologic issues were not found to be associated with cleft type.
