Diagnostic imaging methods are very important for patients with bilateral sensourinoural hearing loss. Magnetic resonance imaging (MRI) is able to demonstrate the vestibulocochlear nerve and facial nerve in the internal acoustic canal. Also computed tomography can be helpful to determination of the deficiency of the cochlear nerve. Cochlear nerve anomalies are classified into three group accord...

The most frequent complaint of individuals with hearing loss is poor understanding of spoken language. Recent findings in the study of the function of brain, the final site of language recognition, examined among individuals with hearing loss are as follows. In prelingually deaf children, language recognition usually does not improve much with input from cochlear implant, but we experienced one...

Nineteen adults and 9 children who received a unilateral cochlear implant between 2002 and 2007 were included in the study. All subjects were preoperatively diagnosed with significant residual hearing in low frequencies, termed as 'partial deafness', and were implanted according to a 6-step round window surgical technique for partial deafness cochlear implantation. Hearing was preserved to a gr...

The most common type of hearing loss results from damage to the cochlea including lost hair cells (HCs) and spiral ganglion neurons (SGNs). In mammals, cochlear HC loss causes irreversible hearing impairment because this type of sensory cell cannot regenerate. The protection from SGN from degeneration has implications for cochlear implant to patients with severe deafness. This review summarizes...

Mutation of the Gap Junction Beta 2 gene (GJB2) encoding connexin 26 (CX26) is the most frequent cause of hereditary deafness worldwide and accounts for up to 50% of non-syndromic sensorineural hearing loss cases in some populations. Therefore, cochlear CX26-gap junction plaque (GJP)-forming cells such as cochlear supporting cells are thought to be the most important therapeutic target for the ...

Children using unilateral cochlear implants abnormally rely on tempo rather than mode cues to distinguish whether a musical piece is happy or sad. This led us to question how this judgment is affected by the type of experience in early auditory development. We hypothesized that judgments of the emotional content of music would vary by the type and duration of access to sound in early life due t...

For some individuals with severe high-frequency hearing loss, hearing aids cannot provide a satisfactory improvement in speech recognition. However, these same patients often have too much residual hearing to qualify as candidates for a cochlear implant. Here we describe results with the Iowa/Nucleus Hybrid cochlear implant, which is designed to preserve the patient's residual low-frequency hea...

Background: The birth of a child with a hearing disability is a stressful event in the family. Since consanguineous marriages are associated with the incidence of congenital hearing loss, it is expected that such parents will experience greater psychological problems. Objective: The current study investigated and compared anxiety, depression, and stress i...

OBJECTIVES: The mechanism of hearing loss in Paget’s disease of bone was investigated. The present study was a systematic, prospective, controlled set of clinical investigations to test the hypothesis that there is a general underlying mechanism of hearing loss in Paget’s disease of bone and to gain additional insights into the auditory and otologic dynamics of this disease. Specific questions ...
