...Takanobu Kunihiro; Jin Kanzaki; Shigemitsu Yoshihara; Yasuo Satoh The prognosis and the recovery process of facial nerve paralysis were reviewed in 74 patients who, despite preservation of nerve continuity, showed no facial movement after acoustic neuroma resection. In 50 or 67.6% of patients...

...Hidekazu Tanaka; Atsushi Komatsuzaki; Hitoshi Hentona The effects of the stimulus rate on the auditory brainstem reponses (ABRs) of acoustic neuroma (AN) patients were studied. Ninety-decibel click stimuli at a normal hearing level were delivered at stimulus rates of 9.5,20,40 and 90 Hz, and ABRs...

...Hidekazu Tanaka; Atsushi Komatsuzaki; Hideji Okuno The electrically evoked auditory brainstem response (EABR) was recorded by direct electrical stimulation of the cochlear nerve in 8 acoustic neuroma patients. The EABR by electrical stimulation of the cochlear nerve at the fundus of the internal...

... in patients whose nerve continuity is preserved during surgery for acoustic neuroma. The orbicularis oris, frontal, and orbicularis oculi muscles were examined for the occurrence of MUAPs in 48 such patients. In 30 patients who recovered from complete paralysis within 10 months after surgery, MUAPs...

...T. Kunihiro; J. Kanzaki; S. Yoshihara; Y. Satoh; A. Satoh Facial movement following hypoglossal-facial nerve anastomosis was investigated in 29 acoustic neuroma patients. The amount of facial movement was assessed using both the grading system of House and Brackmann and the revised grading scale...

...Hidekazu Tanaka; Atsushi Komatsuzaki; Hitoshi Hentona; Yoshihiro Noguchi Auditory brainstem responses (ABRs), electrocochleograms and the evoked potentials from the internal auditory canal were recorded simultaneously in 3 acoustic neuroma (AN) patients. The neural conduction in the internal...

...Jin Kanzaki The incidence of cases of acoustic neuroma that are manifested as sudden deafness or progressive sensorineural hearing loss was investigated. The findings of the stapedius reflex test, the auditory brain stem response test and the caloric test were analyzed, and the procedure...
