Brown MG. Keyser B. Rothenberg ES. Journal of Hand Surgery - American Volume. 17(6):1009-11, 1992 Nov. We have performed 149 consecutive one-portal and 152 consecutive two-portal endoscopic carpal tunnel release operations. Average time to cessation of preoperative symptoms was 15 days in both the one-portal and two-portal groups. The average time of return to work was 16 days in the one-portal group and 17 days in the two-portal group. The complication Á rate in the one-portal group was 6%, and in the two-portal group it was 5%. In our opinion, the one-portal release technique is much more difficult and inherently more dangerous than the two-portal technique, and we recommend the latter for endoscopic carpal tunnel release. *
