In a prospective study, we compared open and endoscopic carpal tunnel release. From 1993 to 1994, 40 patients were operated. In 20 patients (group A) we performed an endoscopic release of the retinaculum flexorum combined with a release of the ligamentum carpi palmare. In 20 patients (group B), we performed an open release of the retinaculum flexorum, of the ligamentum carpi palmare and a neurolysis of the nervus medianus. Preoperatively, we did X-ray, clinical and electroneurographic examinations. All patients in group A and B were controlled ten days, six weeks, and three months postoperatively. The control of the electroneurographic parameters was done three months postoperatively. We did not find any significant difference between the two groups as to the X-rays, the clinical parameters and the results of the improvement of the median motor latency, the NPA and the median sensory latency. In group A as well as in group B, the improvement of the sensory latency and the distal latency was significantly higher, the improvement of the distal latency was significantly higher in group B. The duration of the surgery was significant shorter as well as the return to work for the patients with an endoscopic release.
在一项前瞻性研究中，我们比较了开放性和内镜下腕管松解术。1993年至1994年，对40例患者进行了手术。在20例患者（A组）中，我们进行了屈肌支持带的内镜下松解并联合腕掌侧韧带松解。在另外20例患者（B组）中，我们进行了屈肌支持带、腕掌侧韧带的开放性松解以及正中神经松解术。术前，我们进行了X线、临床和神经电生理检查。A组和B组的所有患者在术后10天、6周和3个月进行了复查。神经电生理参数的复查在术后3个月进行。在X线、临床参数以及正中运动潜伏期、NPA和正中感觉潜伏期改善结果方面，我们未发现两组之间存在任何显著差异。在A组和B组中，感觉潜伏期和远端潜伏期的改善均显著更高，B组远端潜伏期的改善显著更高。内镜下松解患者的手术时间显著更短，恢复工作的时间也更短。
