In this study, we aimed to compare the clinical findings and ENMG results of the patients who underwent surgery due to CTS, in the preoperative and early postoperative period. Methods: 33 wrists of 29 patients who underwent open carpal tunnel surgery in our clinic due to CTS, between 2009 and 2011, were evaluated. Electrophysiological progress was evaluated with ENMG and clinical state with Boston scale. Results: A significant decrease was observed in the postoperative BS symptomatic (SSS) and functional (FSS) scores of patients as compared to preoperative period (P=0.00). In the electrophysiological findings, statistically significant improvement was observed in all groups but very severe CTS group (P<0.05). When preoperative and postoperative EMG findings were compared, changes in DSL and DSA values were statistically significant (P<0.05). However, no statistically significant difference was seen between DML (P=0.085) and DMA (P=246) values on the 3rd month. When an examination was conducted on the patients whose DML and DSL values could not be obtained in the preoperative EMG, DML values were obtained in the early postoperative period in 6 of 7 cases (85.71%, P<0.001), and DSL values were obtained in 17 of 24 cases (70.8%, P<0.000). Conclusions: Sensory nerve findings were more significant, showed faster recovery compared to motor nerve findings, and accompanied the clinical recovery. Performance of an EMG test, especially on sensory nerves, will be more effective in patients selected in the early period, with the exception of patients with very severe CTS.
