To summarize the operation experience of resecting petroclival region tumors by lateral approaches.
(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.
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.
Lateral approaches are recommended for total resection of petroclival region tumors. HoVDever the operative techniques are complex and potential risks of morbidity exist.
总结经外侧入路切除岩斜区肿瘤的手术经验。
对61例岩斜区肿瘤患者采用（1）改良翼点入路；（2）颞枕经小脑幕经岩骨入路；（3）经岩骨联合幕上下乙状窦前入路；（4）远外侧经髁入路。
61例肿瘤中，54例全切，6例近全切，1例次全切。本组无手术死亡病例，随访37例，效果满意。45%的患者出现脑神经功能障碍，最常见的是Ⅲ、Ⅵ、Ⅴ、Ⅷ、Ⅸ、Ⅹ、Ⅻ脑神经功能障碍。
推荐经外侧入路全切岩斜区肿瘤。然而，手术技术复杂，存在潜在的并发症风险。
