Abstract 【Objective】To investigate the clinical effect of reconstruction sensory of reverse dorsal digital island flap of fingertip defects.【Methods】A total of 70 patients with 78 fingertip defects in our hospital from January 2015 to December 2016 were collected in the study. All patients underwent reconstruction sensory of reverse dorsal digital island flap and anastomosis of nerve branch and intrinsic nerve stump.【Results】In this study, skin blisters occurred in 5 cases of 7 fingers 3d after operation and healed after symptomatic treatment. The remaining flaps successfully survived and wounds healed very well. The rate of superficial sensory recovery at 6 months after operation was 100.00%, which was significantly higher than 76.92% and 0.00% at 3 months and 1 month after operation (P<0.05). All patients recovered from deep pain at one month after operation. At 6 months after operation, the two-point discrimination was (5.48±1.14) mm, which was significantly less than that of the postoperative 3 months (P<0.05). The sensory recovery of the flap at 6 months postoperatively was significantly better than that at 1 and 3 months postoperatively and the ratio of S4 reached 61.54% (48/78).【Conclusion】Reconstruction sensory of reverse dorsal digital island flap of fingertip defects is an effective method to restore the skin flap.
