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.

AbstractA prospective study of hearing loss in 120 cases with non-explosive blast injury of the ear, gathered over a six-year period, is presented. Thirty-three (27.5 per cent) patients had normal hearing, 57 (47.5 per cent) conductive hearing loss, 29 (24.2 per cent) mixed loss and one (0.8 per cent) had pure sensorineural loss. The severity of conductive hearing loss correlated with the size of the eardrum perforation; only a marginal difference was found between water and air pressure injuries, with respect to this type of hearing loss. Of all locations, perforations involving the posterior-inferior quadrant of the eardrum were associated with the largest air-bone gap. Audiometric assessment revealed that none of the patients suffered ossicular chain damage. Three patterns of sensorineural hearing loss were identified: a dip at a single frequency, two separate dips, and abnormality of bone conduction in several adjacent high frequencies. Involvement of several frequencies was associated with a more severe hearing loss than a dip in a single frequency. Healing of the perforation was always accompanied by closure of the air-bone gap, while the recovery of the sensorineural hearing loss was less favourable.

Conductive Hearing

Occlusion effects were determined and compared on three groups of subjects (20 normal hearers, 20 with conductive hearing loss, and 20 with sensorineural hearing loss). As in previous studies, the occlusion effects of the conductive group were clearly different from those of the other two groups, especially at 250 Hz. Two procedures are discussed which use the principle of the Bing test to determine when and how to compensate for the occlusion effect while masking for bone conduction.

AbstractThirty-four ears with conductive hearing loss due to otosclerosis were operated upon using the laser stapedotomy technique. Audiological results were compared with the results of 316 non-laser stapedotomies. The post-operative air-bone gap, calculated as the difference between the postoperative air and bone conduction levels, was smaller with the laser stapedotomy group. Also, the bone conduction showed significant improvement with the use of laser.Significant sensorineural hearing loss was not found in any of the laser-treated patients. According to our results, we concluded that laser is of benefit in stapes surgery for improving the hearing results and minimizing the inner ear trauma.

<p class="abstract"><strong>Background:</strong> Chronic squamosal otitis media can occur due to many conditions affecting the middle ear. Most common sign of developing a chronic squamosal otitis media is formation of a retraction pocket in the tympanic membrane leading to further development of a cholesteatoma and if not treated properly, may lead to development of dangerous complication in the affected ear. These etiological factors may also affect the other ear. It is therefore very necessary to assess and diagnose the contralateral ear, so that the disease can be intervened and treated at the right time, to prevent any deterioration in hearing of the contralateral ear.</p><p class="abstract"><strong>Methods:</strong> The prospective study was done in 100 patients with unilateral chronic squamosal otitis media, where the contra lateral ear was examined and assessed for any hearing loss.  </p><p class="abstract"><strong>Results:</strong> We found hearing loss in the contra lateral ear ranging from mild conductive hearing loss to sensorineural hearing loss with the maximum patients with mild conductive hearing loss (42%) and lowest in sensorineural hearing loss (1%).  </p><p class="abstract"><strong>Conclusions:</strong> In our study, 76 patients were seen with conductive hearing loss. Out of that, 42% patients were seen with mild conductive hearing loss, 30% with moderate conductive hearing loss and 4% with severe conductive hearing loss. 20% patients were seen with normal hearing. 3% patients were seen with mixed hearing loss and only 1% patient was seen with sensorineural hearing loss in contralateral ear.</p>

Objective: The aim of this paper was to compare the accuracy of a smartphone-based Weber test (SPWT) with the traditional tuning fork Weber test (TFWT) in identifying and differentiating between sensorineural hearing loss (SNHL) and conductive hearing loss (CHL). Study Design: We conducted a prospective, noncontrolled clinical study. Methods: Sixty patients referred to the emergency department due to unilateral hearing loss (HL) were enrolled. They were asked to press a single uncovered smartphone on their forehead and conduct a Weber test by means of the smartphone’s vibration application. The results were compared to the TFWT. Results: Twenty-six (43%) patients were diagnosed with a SNHL, and 34 (57%) with a CHL. The SPWT was in agreement with the TFWT (at a frequency of 512 Hz) in 55 (92%) patients. The sensitivity and specificity of the TFWT were 84.6 and 94.1%, respectively. The sensitivity and specificity of the SPWT were 76.9 and 97.1%, respectively. Conclusion: SPWT can serve as an auxiliary diagnostic tool in the absence of a 512-Hz tuning fork to assist in the identification of the type of HL and to potentially hasten the diagnosis and provision of treatment when indicated.

The Audiant Bone Conductor has been heralded as an aid for use in conductive hearing loss; however, its possible use in unilateral sensorineural hearing loss (SNHL) has also been proposed. Between July 1987 and July 1989, profound unilateral sensorineural hearing loss has been rehabilitated In 43 patients using the Xomed Audiant Bone Conductor. Patients who were willing to participate in this clinical trial and who were felt to be good contralateral routing of signals (CROS) aid candidates were selected preoperatively. Audiometric followup, selection criteria, patient satisfaction, and complications are discussed.

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.

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.

This case study summarizes findings in an adult male, aged 57, who presented to the Adult Audiology Clinic with aural atresia in the right ear resulting in a conductive hearing loss and a sudden sensorineural hearing loss in the left ear. Treatment options included reconstruction surgery in the right ear, bone anchored hearing aid in the right ear to overcome the conductive hearing loss, bone anchored hearing aid in the left ear for single sided deafness, and intratympanic steroid injections in the left ear to salvage hearing.This case study highlights that when a patient is educated on all available options the patient is then able to make a decision comfortable to him and to help improve his hearing.
