锁孔入路显微手术切除颅底肿瘤

目的 探讨锁孔入路显微手术切除颅底肿瘤的手术技巧和适应证。方法 分别经眶上、翼点、眉间、颞下和枕下乙状窦后锁孔入路采用显微外科技术切除颅底肿瘤18例,内窥镜辅助的显微外科技术切除颅底肿瘤4例。结果 肿瘤全切除13例,次全切除6例,大部分切除3例,无锁孔入路相关严重并发症和手术死亡。结论 锁孔入路显微手术切除颅底肿瘤具有创伤小、脑牵拉损伤轻、术后恢复快的优点,适合于病灶范围相对局限的颅底肿瘤。

Resection of skull base tumour through a keyhole approach

Objective The objective of this paper is to i nv estigate operative techniques and indications for skull base tumour removal thro ugh keyhole approach. Methods Twenty-two cases of skull base tumour underwent microsurgery or endoscope-assisted microsurgery, through a key hole approach, via supraorbital, glabellar nasal, pterional, subtemporal and su boccibital retrosigmoidal entrance. Eighteen cases of skull base tumour was rem oved by microsurgery and 4 cases, by endoscope-assisted microsurgery. R esults The tumour was totally removed in 13 cases, sub totally removed in 6 and largely removed in 3. No serious complication related to keyhole surgery was fo und and there was no operative death. Conclusion Keyhole surger y may provide maximum efficiency to remove skull base tumour and minimum brain retractor injury and can be used for confined skull base tumours.
