Unexplained Variation in Benefit of Treatment of Congenital Unilateral Aural Atresia: A Review of the Literature.

Objective: A review of published data regarding binaural hearing after treatment of congenital unilateral conductive hearing loss (UCHL) due to aural atresia. Treatment options concern atresia surgery (reconstructive surgery), application of a bone conduction device (BCD), or application of a middle ear implant (MEI).

Data Sources: Database PubMed was searched for articles published in English and German between January 1, 1994, and January 1, 2019.

Long-term subjective benefit with a bone conduction implant sound processor in 44 patients with single-sided deafness.

Introduction: Studies that investigate the subjective benefit from a bone conduction implant (BCI) sound processor in patients with single-sided sensorineural deafness (SSD) have been limited to examining short- and mid-term benefit. In the current study, we performed a survey among 44 SSD BCI users with a median follow-up time of 50 months.

Materials And Methods: Forty-four experienced SSD BCI users participated in the survey, which consisted of the Abbreviated Profile of Hearing Aid Benefit, the Single-Sided Deafness Questionnaire, the Short Hearing Handicap Inventory for Adults, and a self-made user questionnaire.

An experimental objective method to determine maximum output and dynamic range of an active bone conduction implant: the Bonebridge.

Introduction: Recently, a new active bone conduction implant, the Bonebridge, was introduced. This transcutaneous device is proposed as an alternative to previous percutaneous systems. The current study aims to determine the maximum output (MO) of the Bonebridge by making use of Bonebridge-generated sound pressure levels in the occluded ear canal of the unaided ear.

A comparative study on speech in noise understanding with a direct acoustic cochlear implant in subjects with severe to profound mixed hearing loss.

The aim of this study was to investigate the efficacy of a direct acoustic cochlear implant (DACI) for speech understanding in noise in patients suffering from severe to profound mixed hearing loss (MHL) due to various etiologies compared to the preoperative best-aided condition. The study was performed at five tertiary referral centers in Europe (Belgium, Germany, Poland and Spain). Nineteen adult subjects with severe to profound MHL due to (advanced) otosclerosis, ear canal fibrosis, chronic otitis media, tympanosclerosis or previous cholesteatoma were implanted with a DACI (Codacs™ Investigational Device) combined with a conventional stapes prosthesis.

Comparison of sound processing strategies for osseointegrated bone conduction implants in mixed hearing loss: multiple-channel nonlinear versus single-channel linear processing.

Objectives: Evaluation of a single-channel linear bone conduction implant sound processor (S-BCI) and a multiple-channel nonlinear bone conduction implant sound processor (M-BCI) with objective and subjective measures in patients with mixed hearing loss.

Study Design: In total, 20 patients with mixed hearing loss were included in the study. For either sound processor aided thresholds and speech perception in quiet with monosyllables were measured.

Comparison of 2 implantable bone conduction devices in patients with single-sided deafness using a daily alternating method.

Objective: Comparison of the auditory and subjective capabilities of 2 implantable bone conduction devices BAHA Divino sound processor (Divino) and the BAHA BP100 sound processor (BP100) using a daily alternating method.

Study Design: Open prospective comparative trial.

Setting: Tertiary referral otology and neurotology center.

Clinical need for a Baha trial in patients with single-sided sensorineural deafness. Analysis of a Baha database of 196 patients.

A bone-anchored hearing aid (Baha) is used in patients with single-sided sensorineural deafness (SSD) to overcome the head shadow effect. Of all the patients with SSD, treated at our hospital, 196 patients used a Baha on trial between November 2001 and April 2010. The objective of this study is to evaluate what factors determine the decision of a SSD patient whether or not to opt for a Baha device following a Baha trial period.
