经侧方入路切除岩骨-斜坡区肿瘤

目的 探讨经侧方入路切除斜坡肿瘤的治疗效果。方法 对６１例岩骨斜坡区肿瘤患者分别采用以下手术入路：（１）改良翼点入路；（２）颞枕经天幕，岩骨入路；（３）经岩骨乙状窦前幕上，下联合睡；（４）远外侧经髁入路。结果 ６１例岩骨－余坡区肿瘤，全切５４例，近全切除６例，大部切除１例，无手术死亡。６１例中，其中有３７例患者术后得到了随访，结果满意。

Lateral approaches for treatment of petroclival region tumor

Objective To summarize the operation experience of resecting petroclival region tumors by lateral approaches Methods (1) Ameliorate pterion approach;(2) temporal occipital transtentorial transpetrous approach;(3) transpetrous combined with supratentorial and infratentorial presigmoid approach; (4) far lateral transcondylar approach were applied for 61 patients with petroclival region tumor. Results Of the 61 tumors studied, 54 were completely resected, 6 were nearly complete and 1 was subtotally resected. No patient died in this group, 37 patients were followed up, and all showed satisfying results 45% of the patients had CNs deficit, with III, VI, V, VIII, IX, X, XII nerve deficits most commonly seen. Conclusion Lateral approaches are recommended for total resection of petroclival region tumors HoVDever the operative techniques are complex and potential risks of morbidity exist
