Abstract

Congenital melanocytic nevi are one of the newborns' most common skin lesions, which can cause loss of aesthetics and turn into melanoma. Our study provides information on the clinical features and evidence on the results of treating congenital facial nevus utilizing skin grafting. The results showed that the clinical features of congenital nevus in the upper face are 46 most common oval-shaped masses (43.4%), black color (76.1%), most common in the cheek area (29.9%), with small size (≤3cm) most common (41.3%). All 25 patients were completely cleared of the nevus by using skin grafts and combined with serial excision in most cases (accounting for 56%). The donor site for skin graft is mainly post-auricular (67.4%), and the most common surgical unit for skin grafting is the eyelid (100%) and the nose (93.3%). The incidence of anatomical units for skin grafts is mostly 1 unit (48%) and leastly for 5 units (only 4%). Treatment results were good in 42 grafts (97.7%), average in 1 graft (2.3%), and nografts got poor results in the short term. The long-term result was good in 41 grafts (95.3%) and average in 2 grafts (4.7%). Most of the grafts have the matching color with as the surrounding tissue, minor contracture of tissue around the graft, and the scars at the donor and recipient sites are minimal; there are no cases of recurrence at distant follow-up and the parents. All were satisfied with the results of the treatment. In conclusion, thickness skin graft is a simple, safe, and effective technique for treating congenital facial nevus.
