ObjectiveTo explore the surgical techniques and clinical effects of the mini wraparound flap supplied by the first dorsal digital artery for nail bed reconstruction.MethodsFrom Jan 2012 to Jan 2016,the mini wrap-around flap supplied by the first dorsal digital artery was harvested to reconstruct nail bed defect,including 12 cases in thumb,7 cases in the index finger,2 cases in the middle finger and 2 cases in ring finger.The size of the defects ranged from(6 mm×12 mm)－(14 mm×28 mm).The donor sites were directly closured,or covered with full-thickness skin grafts and pedicle flaps. ResultsAll the flaps were survived.Patients were followed up for 6－48 months.Twenty-three cases were all satisfied with near-normal appearance and good function.No significant morbidity was observed at the donor site and the function was not affected.ConclusionMini wraparound flap supplied by the first dorsal digital artery is an excellent method for entire or partial nail bed reconstruction.
