经口咽入路显微减压术治疗颅颈区畸形腹侧型

Transoral Microsurgical Decompression to the Craniocervical Abnormalities with Ventral Compression

目的 :探讨颅颈区畸形腹侧型经口咽入路显微减压术的疗效 .方法 :对经MRI检查确诊为颅颈区畸形腹侧型的 15例患者 ,采用经口咽入路显微手术切除齿状突、斜坡下部及增生的结缔组织 ,解除其对延颈髓的压迫 .结果 :痊愈 12例 (80 % ) ,好转 2例 (13 3% ) ,无效 1例 (6 7% ) .手术并发脑脊液漏 1例 ,软腭裂开 1例 ,经治疗痊愈 .结论

Objective: To study the transoral microsurgical decompression outcome in the patients with the craniocervical abnormalities of ventral compression. Methods: 15 patients with the craniocervical abnormalities of ventral compression were diagnosed by MRI scanning. Transoral microsurgical decompression was performed by removing odontoid process, lower 1/3 of clivus and proliferated connective tissues. Results: Good recovery in 12 (18%), improvement in 2 (13.3%), and no changes in 3 (6.7%). The complications related to the surgery were cerebral-spinal fluid leakage (n=1), palate dehiscence (n=1). Conclusion: Transoral mirosurgical decompression is the first selection of treatment for craniocervical abnormalities with ventral compression.
