摘要
目的探讨经岩骨-乙状窦前入路切除岩斜区肿瘤双骨瓣成形的临床效果。方法对14例岩斜区肿瘤采用经岩骨-乙状窦前入路行肿瘤切除双骨瓣成形术,先取颞枕游离骨瓣(乙状窦后),再通过磨钻,游离出乳突表面骨瓣(乙状窦前)。保留骨性半规管、耳蜗的完整性,避免将乳突及岩骨根部大部分切除。结果肿瘤全切除8例,次全切除3例,部分切除3例。术后2例脑脊液耳漏,无皮下积液、颅内感染等并发症,无死亡。14例术后3、6个月随访,无并发症发生。结论经岩骨-乙状窦前入路手术中采用双骨瓣成形术后脑脊液漏、皮下积液、颅内感染等并发症少,手术创伤小,安全性高。
Objective To evaluate the efficacy of double flap reconstruction after craniectomy through transpetrosal-presigmoid approach in the treatment of petroclival tumor.Methods A total of patients with petroclival tumor were enrolled in this study.Craniectomy was performed on them through the transpetrosal-presigmoid approach,and then double flap reconstruction was carried out.After the temporo-occipotal free osseous flap(retrosigmoid flap)was obtained,the superficial flap of the mastoid process(presigmoid flap)w...
