청신경종양 적출 후 감각신경성 난청의 회복 = A Case of Marked Hearing Improvement after Surgical Removal of Vestibular Schwannoma with Profound Hearing Loss

다국어 초록 (Multilingual Abstract)

The preoperative hearing status is one of the important factors to determine the method of surgical approach to the vestibular schwannoma. It has been widely recognized that the hearing preservation surgery is not valuable if the patient has no serviceable hearing. The worldwide reported cases of hearing improvement after surgical removal of vestibular schwannoma with profound hearing disturbance are extremely rare, and so far, there have been no domestic cases reported. The authors have experienced a case of significant hearing improvement after surgical removal of vestibular schwannoma with preoperative unilateral total deafness but with normal otoacoustic emission response. We report this case with literature review.
