暴露桥小脑角肿瘤的手术经路较多,但均有其局限性。1980年Jenkins介绍了一种能切除较大听神经瘤的经耳径路,它克服了通常经迷路切除听神经瘤所受到的限制。本文主要介绍它的一种改良法,此法消除了因面神经前移而发生的暂时性面瘫,又不减少经耳途径的充分暴露,经Zurich应用10例直径在1.5～3.5cm之间的内耳道肿瘤暴露,似具有更大的优越性。术后9例面神经功能正常。手术方法:于距耳郭后皱折2cm处先作一“C”形切口,继将切口上端作越过耳郭顶的延长,再延伸2cm;下方向下颌角下延长2cm。向
Exposure of cerebellopontine angle tumor surgery more, but have their limitations. In 1980, Jenkins introduced an ear canal that excises larger acoustic neuromas, which overcomes the limitations that are commonly encountered with excised acoustic neuromas. This article describes its an improved method, this method to eliminate the temporary facial paralysis due to facial nerve advance occurred without reducing the full exposure of the ear channel, the use of Zurich 10 cases of diameter 1.5 ~ 3.5cm between the inner ear Road tumor exposure, it seems to have greater advantages. Nine cases of facial nerve function was normal. Surgical methods: at a distance of 2cm away from the ear Guo Guo first make a “C” shaped incision, following the incision beyond the top of the ear Guo Guo extension of the top, and then extended 2cm; under the mandibular angle to extend 2cm. to
