目的分析脊髓空洞症外科治疗疗效的影响因素。方法采用多因素逐步回归分析方法，对７８例获得随访者以年龄、性别、病程、感觉障碍、运动障碍、合并Ｃｈｉａｒｉ畸形、空洞最大径和手术方式为自变量进行疗效分析。结果运动功能障碍、空洞大小、病程和年龄依次是影响疗效的主要因素，而手术方式、合并Ｃｈｉａｒｉ畸形、感觉障碍和性别对疗效影响不大。结论多因素分析疗效结果较为可靠；综合评价患者病情，科学选择手术适应证并采取适当的手术方式是提高疗效的主要因素。
Objective To analyze the influencing factors of surgical treatment of syringomyelia. Methods The multivariate stepwise regression analysis was used to analyze the curative effect of 78 patients who were interviewed on the basis of age, gender, duration of disease, sensory disturbances, dyskinesia, combined Chiari deformity, maximum cavity diameter and surgical modality. Results Motor dysfunction, cavity size, course of disease and age were the main factors affecting curative effect in turn. However, surgical modality, combined Chiari malformation, sensory disturbance and gender had little effect on curative effect. Conclusions Multivariate analysis shows that the curative effect is more reliable. Comprehensive evaluation of the patient’s condition, selection of surgical indications scientifically and proper operation method are the main factors to improve curative effect.
