METHODS A prospective analysis of 100 normal persons (aged from 18 to 59 years), who were treated by using the vertical plane swing test… (More)
OBJECTIVE To investigate the changes of the potentials and structure of the guinea pig cochlear during whole cochlear perfusion with glutamate. METHODS Cochlear microphonics (CM), compound action potential (CAP), distortion product otoacoustic emission (DPOAE) and auditory brainstem response (ABR) were measured to indicate the cochlear functional… (More)
OBJECTIVE To evaluate the diagnostic value of ENG in occupied lesions of cerebellopontine angle. METHOD Twenty-four cases of pathological confirmed occupied lesions of cerebellopontine angle were examined with ENG before operation. The ENG examination included saccade test, gaze test, ocular pursuit test, optoknetic test, positional test and positioning… (More)
Bush spike wave was a kind of wave during ENG-Gaze test. We analysed 440 cases. The results showed that appearance rate of organic lesions of the brain was 55%, peripheral and other lesions were few. So bush spike wave might be of certain value in differential diagnosis of central lesions.
