We describe the technique of cosmetic reconstruction after mastoidectomy in the transpetrosal-presigmoid approach for petroclival lesions.
This technique involves raising a single temporo-occipital bone flap and cosmetic mastoidectomy, removing the mastoid bone fragments (by means of a rongeur instead of an air drill) for later reconstruction. Replacement of the bone fragments mixed with fibrin glue enables tamponade against the dura to be achieved without a fat graft.
Computed tomographic scans and plain cranial films taken a few years later showed successful reconstruction of the mastoid bone with a good appearance of the retromastoid area in seven patients who underwent this procedure. The only complication was infection in one patient from cerebrospinal fluid leakage from the wound.
We have developed a simple and easy technique of cosmetic reconstruction after the transpetrosal-presigmoid approach.
我们描述了经岩骨-乙状窦前入路切除岩斜区病变后进行乳突切除术后美容重建的技术。
该技术包括掀起一块颞枕骨瓣和进行美容性乳突切除术，去除乳突骨碎片（用咬骨钳而非气钻）以备后续重建。将骨碎片与纤维蛋白胶混合后进行置换，无需脂肪移植即可实现对硬脑膜的填塞。
几年后进行的计算机断层扫描和头颅平片显示，7例行该手术的患者乳突骨成功重建，乳突后区域外观良好。唯一的并发症是1例患者因伤口脑脊液漏发生感染。
我们开发了一种经岩骨-乙状窦前入路术后简单易行的美容重建技术。
