The music perception abilities of prelingually deaf children with cochlear implants.

Objective: To investigate the music perception abilities of prelingually deaf children with cochlear implants, in comparison to a group of normal-hearing children, and to consider the factors that contribute to music perception.

Methods: The music perception abilities of 39 prelingually deaf children with unilateral cochlear implants were compared to the abilities of 39 normal hearing children. To assess the music listening abilities, the MuSIC perception test was adopted.

Change of phonation control after cochlear implantation.

Objective: To assess the influence of acquired auditory control on some voice parameters in deaf children and adults after cochlear implantation.

Study Design: Prospective clinical study.

Setting: Tertiary referral center.

Success rate in revision stapes surgery for otosclerosis.

Objective: The aim of this study was to evaluate the hearing results of revision stapes surgery performed because of previously failed operations and to determine the causes of failure.

Study Design: Retrospective review of revision stapes operations.

Setting: Tertiary referral center.

The influence of cochlear implantation on some voice parameters.

Objective: Some of the voice characteristics of deaf people differ considerably from those of speakers with normal hearing. After a cochlear implantation, auditory control of voice production is possible and the quality of the voice is improved. The aim of this study was to investigate the changes in some of the voice parameters in deaf children after cochlear implantation.

Histologic changes on stapedial footplate in otosclerosis. Correlations between histologic activity and clinical findings.

Objective: To quantify the relationship between the stage of histologic changes of the stapedial footplate in otosclerosis and the magnitude of preoperative hearing loss, tinnitus, vestibular disorder, and postoperative improvement of hearing.

Study Design: Retrospective case review.

Setting: Tertiary referral center.

Otoacoustic emissions in central auditory disorders.

Otoacoustic emissions are sounds produced by outer hair cells of cochlea. It is known that they may be useful in assessing hearing loss. The aim of our study was to evaluate their diagnostic capability in separating sensory from neural hearing impairment.

Brainstem auditory evoked potentials and cochlear microphonics in the HMSN family with auditory neuropathy.

Unlabelled: The aim of this work was to assess the he ' g impairment in patients with hereditary motor and sensory neuropathy (HMSN). Elevation of pure tone thresholds in the presence of preserved inner ear function as suggested by cochlear microphonics (CM), absent or markedly abnormal brainstem auditory evoked potentials (BAEP), and elevation of speech perception out of proportion to the pure tone loss were found in the patients. From 28 members of a Gypsy family, we examined two siblings aged 31 and 30 years and their nephew aged 20 years, all suffering from HMSN that was associated with auditory neuropathy.

Pure tone audiogram and speech audiometry in patients with hereditary motor and sensory neuropathy.

The goal of our work was to determine hearing thresholds in patients with hearing impairment due to hereditary motor and sensory neuropathy(HMSN I). In assessment of auditory function we used two methods: pure tone and speech audiometry. Pure tone audiometry was performed using air and bone conducted signals.
