Objective To summarize surgical treatment experience on the extended fron-totemporal approach for resection of middle cranial fossa communicating tumors. Methods Retrospective analysis of surgical treatment experience on extended frontotemporal approach for resection of middle cranial fossa communicating tumors in 42 cases was conducted. Results Total/tumor resection was completed in 32 cases, subtotal resection in 6 cases and partial resection in 4 cases. No operation death was recorded. Symptoms disappeared in 18 cases and improved in 24 cases. Surgical complications: part of sensory root of trigeminal nerve injury in 15 cases, oculomotor nerve injury in 6 cases, optic nerve injury in 3 cases and 1 case with facial nerve injury. Cerebrospinal-fluid leakage was seen in 3 cases, bite dislocation in 1 case and intracranial infection in 1 case. Conclusion With disconnection of the zygomatic arch and lumbar cisterm cerebrospinal fluid drainage to reduce intracranial pressure in operation, extended frontotemporal approach for resection of middle cranial fossa communicating tumors provides wide operative field if the resection of the tumor starts from extracranial part. It can better protect the brain and nerve function and reduce complications.%目的 总结扩大额颞入路切除中颅窝沟通性肿瘤外科治疗经验.方法 回顾性分析扩大额颞入路切除中颅窝沟通性肿瘤42例的外科治疗经验.结果 肿瘤全切除32例,次全切除6例,大部切除4例,无手术死亡.术后症状消失18例,好转的24例.手术并发症:三叉神经感觉根部分损伤15例,眼动神经损伤6例,视神经损伤3例,面神经损伤1例.术后脑脊液漏3例,咬合错位1例,颅内感染1例.结论 扩大额颞手术入路切除中颅窝沟通性肿瘤,术中离断颧弓,腰大池引流脑脊液降低颅内压,术野宽阔,从颅外开始切除肿瘤,可以较好的保护脑和神经功能,减少手术并发症.
