目的 :探讨枕下远外侧经髁手术对颅颈交界腹侧区肿瘤切除的适应证及术式方法。方法 :结合临床显微解剖讨论分析4例颅颈交界区肿瘤手术的情况。结果 :4例颅颈交界区肿瘤采用枕下远外侧经髁术式 ,除 1例髓内肿瘤右上肢肌力无恢复外 ,余 3例均取得满意临床效果。结论 :对比其他传统入路 ,经髁术式有术径短 ,显露清楚 ,脑干牵拉轻 ,对周围结构保护好等优点。是此区大部分肿瘤切除的首选入路。
Objective : To explore the indications and surgical methods for the resection of tumors in the ventral region of the craniocervical junction with far lateral suboccipital transcervical surgery. Methods : The clinical microsurgical anatomy was used to discuss the 4 cases of tumors in the craniocervical junction. RESULTS: Four cases of craniocervical junction tumors were treated with transoccipital far-lateral transthoracic surgery. Except for 1 case of intramedullary tumor, the right upper extremity muscle strength did not recover. The remaining 3 cases achieved satisfactory clinical results. Conclusion: Compared with other traditional approaches, the curative technique has the advantages of short operative diameter, clear exposure, light brain stem pulling, and good protection of surrounding structures. It is the first choice for most tumor resection in this area.
