Hearing in acromegaly

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.

Air Conduction

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.

Conductive Hearing

Controversy exists as to whether individuals with stapedial otosclerosis have elevated bone conduction thresholds due to cochlear involvement by the focus. A comparison was made between the Carhart-corrected bone conduction thresholds in 45 unoperated, non-noise-exposed individuals with stapedial otosclerosis and the thresholds in a matched random sample of the population with no conductive hearing loss. No consistent, significant difference was discerned. It is considered that individuals with stapedial otosclerosis do not in general have elevated bone conduction thresholds compared with control subjects. However, there was a suggestion that there may be a small, progressive elevation of bone conduction thresholds in older patients.

Hearing impairment is a frequent human sensory impairment. It was estimated that over 50% of those aged >75 years experience hearing impairment in the United States. Several hearing impairment–related factors are detectable through screening; thus, further deterioration can be avoided. Early identification of hearing impairment is the key to effective management. However, hearing screening resources are scarce or inaccessible, underlining the importance of developing user-friendly mobile health care systems for universal hearing screening. Mobile health (mHealth) applications (apps) act as platforms for personalized hearing screening to evaluate an individual’s risk of developing hearing impairment. We aimed to evaluate and compare the accuracy of smartphone-based air conduction and bone conduction audiometry self-tests with that of standard air conduction and bone conduction pure-tone audiometry tests. Moreover, we evaluated the use of smartphone-based air conduction and bone conduction audiometry self-tests in conductive hearing loss diagnosis. We recruited 103 patients (206 ears) from an otology clinic. All patients were aged ≥20 years. Patients who were diagnosed with active otorrhea was excluded. Moderate hearing impairment was defined as hearing loss with mean hearing thresholds >40 dB. All patients underwent four hearing tests performed by a board-certified audiologist: a smartphone-based air conduction audiometry self-test, smartphone-based bone conduction audiometry self-test, standard air-conduction pure-tone audiometry, and standard bone conduction pure-tone audiometry. We compared and analyzed the results of the smartphone-based air conduction and bone conduction audiometry self-tests with those of the standard air conduction and bone conduction pure-tone audiometry tests. The sensitivity of the smartphone-based air conduction audiometry self-test was 0.80 (95% confidence interval CI = 0.71–0.88) and its specificity was 0.84 (95% CI = 0.76–0.90), respectively. The sensitivity of the smartphone-based bone conduction audiometry self-test was 0.64 (95% CI = 0.53–0.75) and its specificity was 0.71 (95% CI = 0.62–0.78). Among all the ears, 24 were diagnosed with conductive hearing loss. The smartphone-based audiometry self-tests correctly diagnosed conductive hearing loss in 17 of those ears. The personalized smartphone-based audiometry self-tests correctly diagnosed hearing loss with high sensitivity and high specificity, and they can be a reliable screening test to rule out moderate hearing impairment among the population. It provided patients with moderate hearing impairment with personalized strategies for symptomatic control and facilitated individual case management for medical practitioners.

The conductive SISI (short increment sensitivity index) test is an indirect procedure to estimate bone-conduction thresholds for middle ear pathology patients. A series of SISI tests are run, beginning at 20 dB S.L. and increasing in 10 dB S.L. steps, until a 100% SISI score is obtained. The following equation predicts the bone-conduction threshold: [Formula: see text] The results of 25 conductive SISI tests on a conductive hearing loss group indicate that the equation approximates the measured B.C. threshold. There was no statistical difference between the predicated B.C. thresholds (12.4 dB) and measured B.C. thresholds (10.4 dB) for the group.

Conductive Hearing

Otosclerosis is the most frequent cause of conductive hearing loss in patients with intact tympanic membrane. It can be treated by surgery with various techniques. Because of limited manipulation and comparably similar results, stapedotomy at present is preferred over other surgical techniques by most surgeons. Here we present the operative results of 35 otosclerotic patients who underwent stapedotomy between January 2009 - October 2010 in the department of Otolaryngology- Head & Neck Surgery of Bangabandhu Sheikh Mujib Medical University, Dhaka Medical College Hospital and Shahid Suhrawardhy medical college & hospital, Dhaka. The aim of this study was to evaluate the hearing results following stapedotomy in otosclerosis surgery. The average air-bone gap of patients improved significantly to 21.74 dB after operation. Other hearing parameters of patients (including air conduction, bone conduction, speech discrimination score, and tinnitus) also improved. No patient experienced persistent vertigo after the operation and pre operative tinnitus resolved in 12 out of 22 patients. Stapedotomy is a safe and effective modality for improving conductive hearing loss in otosclerotic patients. Bangladesh J Otorhinolaryngol; October 2019; 25(2): 85-93

Hearing System

Abstract Introduction Bone conduction hearing systems can be applied through non-invasive devices, using soft bands that exert pressure on the skin, or they can be surgically implanted (Bone Anchored Hearing Aid - BAHA). However, these bone conduction devices are frequently not well accepted due to the pressure on the head. Therefore, a new non-surgical hearing system was developed not to exert pressure on the skin, the ADHEAR. The bone anchorage in ADHEAR is performed through an adhesive adapter and is indicated for patients with conductive hearing loss and normal inner ear function. Objectives Evaluate the audiological performance with the adhesive bone conduction hearing device (ADHEAR) in a patient with conductive hearing loss. Methodology The study was designed as a prospective single-subject repeated-measure study with the subject serving as his own control. A 29 year old female patient who had a primary surgery due to middle ear cholesteatoma, was adapted with unilateral non-invasive adhesive bone conduction system for the treatment of conductive hearing loss. Air and bone conduction thresholds, word recognition scores (WRS) and speech recognition thresholds (SRT) in quiet and noise were assessed to verify the inclusion criteria of the study. Aided and unaided pure tone audiometry at 0.5, 1, 2 and 4 kHz in free field and speech audiometry in quiet and noise were performed at baseline and after 4 weeks with the ADHEAR. Results The functional gain with the ADHEAR averaged over 0.5, 1, 2, and 4 kHz after 4 weeks of usage of the adhesive hearing system, improved from 55 dB HL to 31dB HL. Speech perception in quiet and noise improved significantly in the aided situation, with SRT in quiet improving from 60 to 35 dB HL, when compared to the unaided condition. Similar results were found in noise. The patient evaluated the ADHEAR system as being useful, and without complaints of skin pressure. There was no adverse skin reaction. Conclusion Hearing performance was significantly better with ADHEAR under all test conditions. Therefore, this transcutaneous hearing system seems to be an excellent alternative for patients who need a hearing solution for conductive hearing loss but for clinical reasons cannot undergo surgery or conventional hearing aids. Furthermore, it preserves skin over the mastoid and reduces the risk of infection. Otherwise it has benefits verified by absence of head pressure and improvement of patient’s quality of life.
