Open median nerve decompression is the gold standard for carpal tunnel
syndrome; endoscopic median nerve decompression is an alternative. We
compared our first 20 consecutive endoscopic releases with our last 2
0 open releases. The endoscopic procedure employed the two-portal Chow
technique; the open procedure employed the Taleisnik technique. Posto
perative patient assessment was performed by an independent occupation
al therapist blinded to the technique. There was no difference between
the groups with respect to both subjective and objective outcomes. Th
e time of return to work and to all activities averaged 3 and 6 weeks,
respectively, for both groups. The choice between techniques should b
e based on informed consent by the patient in light of available data.
