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 investigate the feasibility of the round window stimulation electrical evoked auditory brainstem response (EABR) test, and optimize the parameters of recording and stimulation electrodes positions. METHOD Ten healthy Hartley guinea pigs (20 ears) were used for the EABR test. The positive stimulation electrodes were placed into the round(More)
OBJECTIVE To develop electrically evoked auditory brainstem response(EABR) modules of REZ-I domestic cochlear implant device, and testify the reliability and validity of the modules. METHODS Postoperative EABR were recorded in guinea pigs by using the self-designed EABR module. RESULTS EABR waves were recorded in all 15 ears of 9 guinea pigs with normal(More)
It is still a difficult clinical issue to decide whether a patient is a suitable candidate for a cochlear implant and to plan postoperative rehabilitation, especially for some special cases, such as auditory neuropathy. A partial solution to these problems is to preoperatively evaluate the functional integrity of the auditory neural pathways. For evaluating(More)
OBJECTIVE To report the way for searching the chorda tympani nerve and the significance for preserving the chorda tympani nerve during canal-wall-down mastoidectomy and tympanoplasty surgery. METHOD Sixty-six cases with chronic suppurative otitis media underwent canal-wall-down mastoidectomy and tympanoplasty surgery. According to the marker of the short(More)
OBJECTIVE To investigate the imaging and clinical feature of leukoencephalopathy with hearing loss first complaint. METHOD The head MRI and clinical feature of 7 cases leukoencephalopathy with hearing loss first complaint were retrospectively analysed, including their place, shape, range and blood plasma very-long-chain fatty acid (VLCFA). RESULT The(More)
OBJECTIVE To compare the singing formant differences between successful opera actors and non-successful opera actors during their adolescence period, and to compare the same index between adolescence and adult period of successful actors. METHODS From 1985 to 1986, the author had 21 adolescent actors' voice recorded, all of them were from Beijing KunQu(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)
