ObjectiveTo explore a reconstruction method for complete nail bed defect caused by various kinds of reasons and to retrospectively analyze the effect of application of free full-thickness skin graft for the whole nail unit repair.MethodsBetween Apr. 2010 and Mar. 2012, the method of free full-thickness skin graft was done for reconstruction of the completely nail unit defect in seven cases. There were 2 male and 5 female patients; the mean age of these patients at the time of surgery was 51.9 years (range: 7 to 70 years). The preoperative diagnoses included two cases of malignant melanoma, one of chronic infection, one of squamous cell carcinoma, two of subungual pigmentation and one of junctional nevus. There were 2 thumb lesions, 3 middle and 2 index finger lesions. Nail unit defect was in the range of 1.5 cm×2 cm to 2.5 cm × 3.5 cm and full thickness skin graft was harvested from the same medial side of upper arm (3 cases), forearm cubital fossa (1 case) and contralateral side of groin region (3 cases).ResultsAll the patients were followed with an average follow-up time being 10 months. All the free skin graft taken was achieved with 100% in all the 7 cases, even in those patients whose partial cortical bone had been curetted. The skin graft was often bluish initially, and superficial blisters were always noticed within 1.5 months postoperatively and the survival skin graft was smooth eventually, and skin graft was adhered to the underlying bone tightly. There was no epidermal inclusion cyst and no residual nail formation. The skin donor sites were without complications. Aesthetic appearance was assessed by the surgeons and found no unacceptable for their patients. And all the patients were satisfied with the cosmetic appearance and active range of motion of their involved fingers, who did not express a desire to undergo any further of nail reconstruction.ConclusionFree full-thickness skin grafting for reconstruction of the complete nail unit defect is a simple, safe and effective procedure which provides a satisfactory aesthetic appearance and does not make any significant skin donor site morbidity especially for middle-aged and elder patients.
