Abstract

Objective To improve the therapeutic effect of the petroclival tumors removed via subtemporal transtentorial approach by microsurgical techniques.Methods Thirty-two patients with tumors in mid-superior petroclival region,admitted to our hospital from January 2005 to December 2011 and underwent microsurgery through subtemporal transtentorial approach.The clinical manifestations,surgical methods and treatment efficacy were retrospectively analyzed.Results Thirty-two patients with tumors included 20 meningiomas,7 neurilemmoma and 5 epidermoid cyst.Total resection was achieved in 22 cases,subtotal resection in 6 cases,and partial resection in 4 cases.Fifteen patients developed new postoperative neurological deficits.The patients were followed up for 3 to 12 months,and the neurological functions recovered in varying degrees.Conclusions The subtemporal transtentorial approach is one of the optimal approaches to remove the mid-superior petroclival tumors because of its mini-invasion and less complications,indicating for a wide application in clinic. Key words: Subtemporal transtentorial approach ; Microsurgery; Petroclival tumors

颞下经幕入路在岩石斜坡中上区肿瘤切除术中的应用

目的提高显微外科技术对经颞下经小脑幕入路石斜坡肿瘤的治疗效果。方法我院2005年1月至2011年12月收治的32例岩石斜坡中上区肿瘤患者，经颞下经额叶入路行显微手术治疗。回顾性分析其临床表现、手术方法及治疗效果。结果32例肿瘤中脑膜瘤20例，神经鞘瘤7例，表皮样囊肿5例。全切除22例，次全切除6例，部分切除4例。15例患者术后出现新的神经功能缺损。随访3 ~ 12个月，患者神经功能均有不同程度恢复。结论颞下经额幕入路侵犯小，并发症少，是切除中上岩斜坡肿瘤的最佳入路之一，具有广泛的临床应用价值。关键词:颞下经额叶入路;显微外科;岩斜肿瘤
