The Effect Of Tenosynovectomy On Patient Outcome In Carpal Tunnel Syndrome Surgery

Carpal tunnel syndrome (CTS) is estimated to be the most frequently seen mononeuropathy, needing surgical intervention. Its prevalence is known to range between 1, and 3 percent. The components contained in this tunnel are the median nerve, four deep digital flexor tendons, as well as four superficial flexors and the tendon of flexor pollicis longus. Between the tendons and bursae an anatomical structure is present called subsynovial connective tissue (SSCT). SSCT absorbs and transmits stress between tendons and the median nerve and it functions as a scaffold for vascular elements. To find out the role of compression or pathologic proliferation of SSCT in the pathogenesis of CTS, we aimed to conduct a study about the surgical technique of this pathology and compared the long- term results of patients operated with or without SSCT excision in our neurosurgery clinic. METHODS: Between 2003 and 2019 we operated 1279 patients at our neurosurgery clinic. Among them 250 patients who had SSCT excision (syn+) were chosen and they were compared with other 250 patients operated without SSCT excision (Syn-). RESULTS: All patients were evaluated preoperatively and 12 months postoperatively based on the results of Boston Carpal Tunnel Syndrome Questionnaire. When pre-, and post-operative results were compared, we didn’t observe a statistically significant intergroup difference. DISCUSSION AND CONCLUSION: Although our primary goal in patients in whom we performed excision of tenosynovium is to relieve the median nerve by increasing decompression, we observed that there was no difference between the two groups in this large-scale study. We think that only liberation of the transverse carpal ligament during surgery will be sufficient.
