枕下进路或迷路进路听神经瘤切除术后可并发脑脊液耳漏或鼻漏,作者采用经乳突颅外修补。1980～1988年共做10例,术后两个月复查均无症状,迄今7例未复发、1例死于他病,2例失联系。术式:耳后切口延至胸锁乳突肌前缘,切口应避开前次手术切口,由正常的皮下组织“桥”将两术区隔开。如前次手术为后颅窝进路则需钻开乳突气房、暴露鼓窦和鼓窦入口,确认漏出部位在乳突气房抑或鼓窦入口,用骨蜡及骨粉混合物封住漏口。去掉砧 Suboccipital approach or lost into the path After acoustic neuroma resection can be complicated by cerebrospinal fluid leakage or rhinorrhea, the author adopted the mastoid extracranial repair. From 1980 to 1988, a total of 10 cases were performed. No symptoms were found in the two months after the operation. So far, 7 cases had no recurrence, 1 died of his disease and 2 cases lost contact. Procedural: ear posterior incision extended to the sternocleidomastoid front, the incision should avoid the previous surgical incision, the normal subcutaneous tissue “bridge” will be separated from the two surgery. If the previous operation for the posterior fossa approach is required to open the mastoidectomy room to expose the drum sinus and the entrance to the drum to confirm the site of leakage in mastoid or drum sinus entrance, with bone wax and bone meal mixture to seal the leak .
