Methods: The authors identified all patients who underwent open carpal tunnel release (62 cases), unilateral endoscopic carpal tunnel release (40 cases), and bilateral endoscopic carpal tunnel release (38 cases) at Cooper University Hospital from January 2012 to January 2014. Cases were identified using CPT billing codes and the data was assessed using an analysis of variance (ANOVA). All endoscopic carpal tunnel releases were done by the same surgeon (AP), and greater than 90% of open procedures were done by a different same surgeon (DF).
Results: The total combined complication rate was 24.7% with no significant difference (p>.05) between techniques. There were no major complications necessitating a return to the operating room. Variables that had a statistically significant difference between groups (p<.05) included mean tourniquet time, mean total procedure time, and return to work as determined from the number of follow-up appointments.
Conclusions: Bilateral endoscopic carpal tunnel release for patients with bilateral carpal tunnel syndrome is less costly than sequential open releases, and because both procedures have equivalent complication profiles, bilateral endoscopic carpal tunnel release is the preferred method for treating bilateral carpal tunnel syndrome.
