摘要
目的通过分析比较中、重度腕管综合征传统与内窥镜微创减压手术后中远期肌电图检测结果的差异，探讨两种方法治疗腕管综合征后肌电指标改善的程度。方法选择中、重度腕管综合征患者共46例59腕，按手术方法的不同分为两组，其中传统切开减压组22例27腕、内窥镜微创减压组24例32腕，于术后1年进行肌电图检测，对复合肌肉动作电位（compoundmuscleactionpotential，CMAP）潜伏期、感觉神经动作电位（sensory nerve action potential，SNAP）波幅及感觉传导速度（sensorynerveconductionvelocity，SNCV）的随访数据进行分析比较。结果术后1年拇短展肌CMAP潜伏期及SNCV组问比较差异有统计学意义（P〈0．05），而SNAP波幅组间比较差异无统计学意义（P〉0．05）。结论神经电生理检测提示传统切开减压治疗中、重度腕管综合征的中远期随访的肌电指标改善程度优于内窥镜微创治疗。
Objective To investigate the extent of electrophysiologic improvement of the two procedures of median nerve decompression after comparing the mid- to long-term electrophysiologic results of endoscopic and open carpal tunnel release of patients with intermediate to severe carpal tunnel syndrome. Methods The clinical data of 46 eases （59 wrists） of carpal tunnel synchrome （CTS） were treated in two groups according to the randomized operation mode, endoscopic carpal tunnel release （ECTR） group （32 wrists in 24 cases） and open carpal tunnel release （OCTR） group （27 wrists in 22 cases）. Nerve conduction study was carried out to record compound muscle action potential （CMAP）, sensory nerve action potential （SNAP） and sensory nerve conduction velocity （SNCV） one year after the carpal tunnel release. CMAP latency, SNAP amplitude and SNCV were analyzed and compared between the two groups. Results The differences in abductor polieis brevis CMAP latency and SNCV one year postoperatively were of statistical significance between the ECTR group and the OCTR group. However, there were no statistically significant differences between the SNAP amplitudes of the two groups. Conclusion The mid- to long-term neuroelectrophysiologic results indicated that the improvement of electrophysiologic indices of conventional OCTR is better than those of the ECTR in treating intermediate to severe carpal tunnel syndrome.
