Unilateral Auditory Neuropathy Caused by Cochlear Nerve Deficiency
Objective. To explore possible corelationship between the cochlear nerve deficiency (CND) and unilateral auditory neuropathy (AN). Methods. From a database of 85 patients with unilateral profound sensorineural hearing loss, eight who presented with evoked otoacoustic emissions (EOAEs) or cochlear microphonic (CM) in the affected ear were diagnosed with unilateral AN. Audiological and radiologic...
متن کاملAuditory neuropathy characteristics in children with cochlear nerve deficiency.
OBJECTIVE To describe a group of children exhibiting electrophysiologic responses characteristic of auditory neuropathy (AN) who were subsequently identified as having absent or small cochlear nerves (i.e., cochlear nerve deficiency). DESIGN A retrospective review of the clinical records, audiological testing results, and magnetic resonance imaging (MRI) studies. Fifty-one of 65 children with...
متن کاملCochlear implantation of auditory neuropathy.
Auditory neuropathy (AN) is a hearing disorder that presents with a grossly abnormal or absent neural response as measured by evoked potentials in the presence of normal outer hair cell function evidenced by present otoacoustic emissions or cochlear microphonics. Rehabilitation for patients with AN is challenging due to abnormal temporal encoding at the auditory nerve leading to severely impair...
متن کاملCochlear implantation in children with labyrinthine anomalies and cochlear nerve deficiency: implications for auditory brainstem implantation.
OBJECTIVES/HYPOTHESIS Compare outcomes among children with inner ear malformations and/or cochlear nerve deficiency (CND) who have received a cochlear implant (CI). STUDY DESIGN Individual retrospective cohort study from 1993 to 2010. METHODS A select cohort of 76 children was identified. Imaging characteristics, operative findings, complications, mapping parameters, and performance were as...
متن کاملAuditory brainstem implantation after unsuccessful cochlear implantation of children with clinical diagnosis of cochlear nerve deficiency.
OBJECTIVES We compared the perceptual auditory abilities of 21 children with suspected cochlear nerve deficiency (CND) and a surgically verified absent cochlear nerve (CN) who first underwent cochlear implantation (CI) and subsequently underwent auditory brainstem implantation (ABI). METHODS In this retrospective cohort study, from 2000 to 2011, 21 children initially underwent CI at an outsid...
