It is not well known how the nonoperated contralateral hand behaves in bilateral @entity923 ( @entity923 ). The postoperative clinical course of the nonoperated contralateral hand in unilateral @entity923 is not well documented either. Of 324 @entity923 @entity1 , the authors studied 37 who had carpal tunnel release on one hand only to evaluate the postoperative outcome of the nonoperated contralateral hand. The other 287 @entity1 had operations on both hands. Seven @entity1 were excluded because of missing data or because they could not be contacted. All 324 @entity1 were subject to clinical and electrodiagnostic studies on both hands. The @entity1 were divided into three groups. Group I was composed of @entity1 who had bilateral @entity923 , diagnosed clinically and electrophysiologically, but who had surgery done only on the hand with the most pronounced symptoms. The @entity1 in group II showed symptoms of @entity923 in one hand only. However, the opposite hand was diagnosed with subclinical @entity923 : Electrodiagnostic studies showed involvement of the median nerve, but without symptoms. Group III was composed of true unilateral @entity923 @entity1 , diagnosed by symptoms and electrodiagnostic study. The results of the electrodiagnosis were categorized according to the severity of @entity16 (mild, moderate, severe). The outcome and postoperative clinical course of the nonoperated contralateral hand were evaluated by electromyography and telephone survey. This method of survey was used because of the vast spread of @entity1 throughout the country. Within 1 year, all 30 operated hands showed significant improvement, 20 of which belonged to group I. Regarding progress of the nonoperated contralateral hand, 10 @entity1 showed improvement of one grade whereas 5 @entity1 showed three grades of improvement. In another 5 @entity1 there was no change whatsoever. In addition, from groups II and III there were 5 @entity1 who showed no change in the nonoperated hand. The postoperative electromyographic findings of the nonoperated contralateral hand was not commensurate with the symptoms. However, regardless of electromyographic results, the nonoperated contralateral hand showed significant improvement (p < 0.0001). @entity1 with unilateral @entity923 did not experience any symptom development in the nonoperated contralateral hand.
