The authors describe a cosmetic mastoidectomy technique for use when performing a combined supra/infratentorial craniotomy and transtemporal exposure. The technique involves a single temporal suboccipital bone flap and cosmetic mastoidectomy, removing the outer table of bone for later replacement. Replacement of the outer table of mastoid bone enables tamponade of a fat graft against the dura to reduce the risk of postoperative cerebrospinal fluid leaks. The technique has been performed in eight patients treated for petroclival meningiomas with excellent cosmetic results.
作者描述了一种在进行联合幕上/幕下开颅手术和经颞部显露时使用的美容性乳突切除术技术。该技术包括单一的颞下枕骨瓣和美容性乳突切除术，去除骨外板以便后期置换。乳突骨外板的置换能够用脂肪移植物填塞硬脑膜，以降低术后脑脊液漏的风险。该技术已应用于8例治疗岩斜区脑膜瘤的患者，美容效果极佳。
