Objective:   To identify factors associated  with patient satisfaction after the decompression  of the median nerve at the carpal tunnel. methods: This study was conducted in 52  patients with carpal tunnel syndrome (CTS) who underwent surgery for median nerve decompression.  The patients were distributed into two groups in relation to the degree  of satisfaction with surgical outcome.  results: The dissatisfied group was younger (p=0.0005) and also showed a higher body mass index (p=0.0028) and preoperative intensity of pain (p=0.0168) compared to the satisfied group. Satisfaction with surgical outcome increased  with age  (p=0.0181) and  decreases with obesity (p=0.0069) and when motor distal latency was greater than 4 ms (p=0.0342). conclusions: Patients with CTS who are  older, have a longer preoperative  motor distal latency and  are  not obese have a greater chance  of satisfaction after median nerve decompression.
