由于内耳道骨性病变所致之耳聋原因有二:一是由于内耳道狭窄,一是由于骨性病变和骨性营养不良侵犯岩锥所致之内耳道畸形。内耳道狭窄 X光片上的内耳道狭窄是多见的,但是狭窄和耳聋之间的关系还需要讨论。 1961年W.House报告了第一例由于内耳道狭窄而引起的耳聋。1969年到1970年,他又和P.E.Brackmann合作对36例怀疑由于内耳道狭窄而引起眩晕的病人进行手术,即通过岩上进路作内耳道减压术,36例病人中26例耳聋,术后3例听力改善,但大多数听力如旧。
Due to intraorbital bone disease caused by deafness there are two reasons: First, due to the narrowing of the ear canal, one is due to bone lesions and osseous malformation caused by rock cone caused by the internal ear canal deformity. Internal auditory canal stenosis X-ray on the narrowing of the internal auditory canal is common, but the relationship between stenosis and deafness still need to be discussed. 1961 W.House reports the first case of deafness due to stenosis of the inner ear canal. From 1969 to 1970, he collaborated with PEBrackmann to perform surgery on 36 patients suspected of having dizziness due to stenosis of the inner auditory canal, ie, decompression of the internal auditory canal through rock access, deafness in 26 of 36 patients, postoperative 3 cases of hearing improvement, but most of the hearing as old.
