<p><b>OBJECTIVE</b>To discuss the therapeutic effect of thenar perforator flaps for the narrow cicatricial contracture at thumb and the first web.</p><p><b>METHODS</b>From Aug. 2010 to Jan. 2012, 9 cases with narrow cicatricial contracture at thumb and the first web, were treated. The defect size after releasing the contracture ranged from 8 mm x 20 mm to 15 cm x 30 mm. The bilateral thenar perforator flaps beside the wound were designed which size was 10 mm x 25 mm to 15 mm x 35 mm. The wounds at donor sites were closed directly.</p><p><b>RESULTS</b>All the 9 flaps survived completely with primary healing. The patients were followed up for 6-18 months. The flaps had soft texture and good appearance. The shape of flaps and function of the fingers were satisfied after 6-18 months of follow-up. There was no scar contracture at incisions in thenar. The thumb motion was really normal. The abduction of first web was 70 degrees - 90 degrees degrees.</p><p><b>CONCLUSIONS</b>The thenar perforator flaps is one of the ideal methods for the treatment of narrow cicatricial contracture at thumb and the first web.
