OBJECTIVE To summarize methods on diagnosis of congenital cochlear nerve canal (CNC) stenosis or atresia and to report results of post-operation such as auditory electrophysiological test and speech test. METHOD Based on temporal bone HRCT and internal acoustic canal MRI, 27 bilateral congenital CNC stenosis/bony atresia cases were distinguished from 3(More)
BACKGROUND Most patients with auditory neuropathy (AN) could receive good even the best effects after cochlear implantation. How to diagnose AN objectively and accurately is very important. In this study, we screened the patients with AN according to the presence or absence of compound action potential (CAP) of intraoperative round window(More)
CONCLUSION The new method of facial recess enlargement through suspending, antedisplacing, and adhering the chorda tympani nerve to the posterior wall of the auditory canal can expose the round window, make electrode insertion easier, and preserve the function of the facial nerve and chorda tympani nerve. OBJECTIVE To describe and report cochlear(More)
OBJECTIVE To discuss the indication and approach of cochlear implantation with common cavity inner ear malformation. METHOD Through imaging examination preoperatively for profound sensorineural hearing loss patients, we found 6 cases with common cavity inner ear malformation, in which cochlear, vestibule and lateral semicircular canal formed a big cavity.(More)
OBJECTIVE To evaluate the indications and surgery time of cochlear implantation in patients with otitis media with effusion (OME). METHODS Cochlear implantation was performed in 26 patients with bilateral profound sensorineural hearing loss and OME. Non-Surgical Treatment was conducted for OME before the following implantation. According to the standards(More)
OBJECTIVE To explore neural response telemetry (NRT) thresholds in patients with stenotic versus normal cochlear nerve canals. STUDY DESIGN Case series with chart review. SETTING Tertiary referral center. SUBJECTS AND METHODS Thirty pediatric patients with profound sensorineural hearing loss in at least 1 ear and no benefit from amplification(More)
OBJECTIVE To find out the changes of voice in different noisy background by computer acoustic analysis. METHOD Twenty-five young people who got normal hearing level and normal vocal cords were selected. They were tested after trained. Sustained /a/,/i/ and sentences were recorded in the three different background: quite, white band noise and speech noise.(More)
