内窥镜辅助下经口咽前路寰枢椎减压术

目的：探讨内窥镜辅助下经口咽前路寰枢椎减压术的临床效果。方法：1998年8月～2004年8月对38例陈旧性寰枢椎脱位患者采用内窥镜辅助下经口咽前入路减压术，其中18例行一期经口咽入路减压和后路枕颈内固定术：15例行经口咽前路寰枢椎复位钢板内固定术；5例不可复型仅行经口咽前入路减压术。结果：平均随访38个月（6～96个月）。术后患者临床症状均明显改善，上颈段脊髓减压改善率达89.3％。发生颅内感染1例，前路钢板松脱1例。结论：与常规减压方法相比，内窥镜辅助下经口咽前路寰枢椎减压手术创伤小，操作精细、准确，术中与助手可协同操作。

Endoscope assisted transoral-transpharyngeal approach to atlanto-axis decompression

Objective:To evaluate the clinical results of endoscope assisted transoral-transpharyngeal approach to atlanto-axis decompression.Method:38 cases of old atlantoaxial dislocation with spinal cord compression were operated for atoanto-axis decompression with endoscope assisted transoral-transpharyngeal approach from August 1998 to August 2004.Result:The mean follow-up was 38 months(6-96 months).All patients had achieved marked recovery on spinal cord function.The average improvement rate of vertebral canal decomression was 89.3%. 1 case occured encephalic infection,1 case occured redislocation after internal fixation.Conclusion:Endoscope assisted transoral-transpharyngeal approach to atlanto-axis decompression has the following advantages,such as less-invesive,operation accurate,field of vision clear and a good cooperation between operator and assistant.
