To evaluate the adverse effects of Chow's two-portal endoscopic carpal tunnel release (ECTR) performed by an experienced surgeon on median nerve function in patients with idiopathic carpal tunnel syndrome, as compared to open carpal tunnel release (OCTR).
Eighty-seven hands subjected to ECTR and 65 hands subjected to OCTR were reviewed. Both groups of patients were similar with regard to age, gender, and severity of the disease. Both groups were compared for the number of hands showing worsening of motor distal latency, sensory conduction velocity, and sensory disturbance after surgery.
Thirteen hands of 12 patients showed worsening of median nerve function after ECTR, while only one hand showed worsening after OCTR. This difference was statistically significant (p=0.0041).
Median nerve damage, although transient or not serious, may occur even if the procedure is done correctly.
与开放性腕管松解术（OCTR）相比，评估由经验丰富的外科医生实施的周氏双切口内镜腕管松解术（ECTR）对特发性腕管综合征患者正中神经功能的不良影响。
回顾了接受ECTR的87只手和接受OCTR的65只手。两组患者在年龄、性别和疾病严重程度方面相似。比较两组术后运动远端潜伏期、感觉传导速度和感觉障碍恶化的手的数量。
12例患者的13只手在ECTR后正中神经功能恶化，而OCTR后只有1只手出现恶化。这种差异具有统计学意义（p=0.0041）。
即使手术操作正确，正中神经损伤也可能发生，尽管可能是短暂的或不严重的。
