摘要
目的 :探讨乙状窦后径路听神经瘤切除术中应用内窥镜的方法及其在减少残瘤发生率中的价值。方法 :常规乙状窦后径路切除听神经瘤 (常规手术组 ) 15例 ,乙状窦后径路加内窥镜检查切除听神经瘤 (结合窥镜组 ) 11例 ,比较其疗效。结果 :常规手术组术后 3例有残留肿瘤 ,而结合窥镜组均为阴性 ;术后听功能、前庭功能障碍发生率及面神经麻痹发生率两组之间差异均无显著性意义。结论 :乙状窦后径路听神经瘤切除术 ,术中使用内窥镜操作方便、安全 ,未出现由此引起的并发症 ,并可防止或减少残留病灶及肿瘤复发的发生率 ,有临床推广应用价值。
Objective:Research into the technique and signification of reducing remnant tumor with utilizing endoscopic technique during removal of acoustic neuroma.Method:15 patients proceeded the removal of acoustic tumor through retrosigmoid approach (as routine retrosigmoid approach operation group, RRSO G), 11 patients utilized endoscope for inspecting and eliminating remain of tumor during the proceed of the removal of acoustic neuroma through retrosigmoid approach (as retrosigmoid approach operation combined using endoscope, RSOCE G), all of them were examined of auditory level, vestibular function,facial nerve function,and MRI before and three months after operation.Result:The remain tumor were found in 3 cases of RRSO G and no any one in RSOCE G after operation. The rates of auditory and vestibular dysfunction,and facial paralysis have no difference between RRSO G and RSOCE G.Conclusion:It is one of expedient and safe surgery methods that the acoustic neuroma are removed through the retrosigmoid approach,and some degrees of hearing function are reserved at same time. If the endoscope is utilized during this operation, the rate of tumor remaining and neuroma recrudescing could be reduced evidently. The acoustic neuroma removed through the retrosigmoid approach combining with utilizing endoscope is a worthy method for using widely in otoneurosurgery.
