RESUMO
While various techniques are used for the reconstruction of fingertip injuries, the main goals remain the same: preserve finger length, sensation, and function. The thenar flap is a well-described technique and simple procedure in fingertip amputations. This study aimed to evaluate the long-term functional and esthetic outcomes along with patient satisfaction of thenar flaps done for fingertip defects. Thenar flaps used in 32 patients operated between January 2010 and December 2016 were analyzed retrospectively to assess sensory recovery, range of motion, cold intolerance, pain relief, appearance, patient satisfaction, and QuickDASH score. All flaps survived, without adverse events. The flap was detached after 10-14 days (mean 12.5 days). The mean follow-up was 31 months (range, 20-45 months). According to Semmes-Weinstein monofilament test results, protective sensation was achieved in 25 patients (78%). The mean static 2-point discrimination was 6.1 mm. There were no functionally significant finger flexion contractures at the final follow-up. Complications such as pain, donor site morbidity and cold intolerance were not encountered. The thenar flap is an excellent technique for coverage of total or subtotal tissue loss of radial-side fingertips that is not accessible to local flaps. It provides good sensory function and appearance when fundamental technical principles (flap design, timing of division, and early mobilization) are respected.
