翼点锁孔入路显微手术切除鞍区肿瘤

目的探讨翼点锁孔入路显微手术治疗鞍区及前颅底肿瘤的方法及效果。方法对19例鞍区及前颅底肿瘤采用翼点锁孔入路开颅显微手术切除。结果肿瘤全切除13例（68．4％），次全切除4例（21．1％），大部分切除2例（10．5％）。无手术死亡病例。术后随访2～18个月，失访2例，无肿瘤复发病例。结论翼点锁孔入路能够充分显露鞍区及前颅底，可达到传统翼点入路相似的手术效果，具有创伤小、脑组织暴露少、出血少、病人术后恢复快等优点。

Microsurgery through Pterional Keyhole Approach for Tumors in Sellar Regions

Objective To explore the technique of microsurgery through pterional keyhole approach for the tumors in the sellar regions and anterior cranial fossae and its therapeutic effect. Methods The clinical data of 19 patients with tumors in the sellar regions and anterior cranial fossae, who underwent microsurgery through pterional keyhole approach from January, 2007 to June, 2008, were analyzed retrospectively. Results Of 19 patients, 13 received total resection of the tumors, 4 subtotal and 2 greatly partial. No patient died of operation. The tumors did not recur in 17 patients who were followed up from 2 to 18 months. Conclusions The satisfactory exposure of the sellar regions and anterior cranial fossae enough to resect the tumors in these regions can be obtained by the microsurgery through the pterional keyhole approach. The microsurgery through the pterional keyhole approach has the merits such as minimal exposure of normal brain tissues, minimal iatrogenic trauma and making the patients quick recovery after the operation.
