Introduction. There is controversy of the impact of the decompressive surgery in the electrophysiological parameters following the procedure in patients with carpal tunnel syndrome (CTS). Objectives. Evaluate the changes in the electrophysiological parameters and evaluate the factors associated to these changes after the surgical decompression of the median nerve in patients with CTS. Methodology. Cross-sectional analytical study of patients with severe CTS submitted to decompressive surgery that have pre and post-surgical electrophysiological studies in Kaelin de la Fuente hospital EsSalud in Lima, Peru between 2015 and 2019. The comparison between the pre and post-surgical changes was evaluated using T-student test for paired samples. The associated factors were analyzed using U-Mann Whitney test or spearman correlation, for categorical variables and numerical, respectively. For the multivariate analysis a multiple simple regression model was used. Results. 55 patients were analyzed. Median nerve´s distal motor latency did not show significant changes after the surgery (-0.47ms; p=0.211). Improvement was found in the distal sensitive latency (-0.5ms; p=0.010), distal motor velocity (2.53m/s; p=0.005), distal motor amplitude (0.9 mV/s; p=0.0048) and distal sensitive amplitude (4.9 mV/s; p=0.034). An association between male and an unfavorable evolution of the distal motor latency of the median nerve was found. (Coefficient β = 2.85, CI 0.453 - 5.248, p = 0.040). Conclusions. Favorable electrophysiological changes after the surgery where evidenced. Male gender and BMI where associated to an unfavorable electrophysiological evolution.
