Background: Congenital giant melanocytic nevus on the face is a challenging condition, especially in the pediatric population. It can produce significant cosmetic deformity with negative psychosocial effects in pediatric patients even after treatment. The objective of this study was to report aesthetic and psychosocial results in the management of congenital melanocytic nevus on the face using multiple reexpansion.

Methods: Data of 6 patients with congenital melanocytic nevus on the face who underwent excision and multiple reexpansion at our center from September 2004 to August 2017, were retrospectively reviewed. To evaluate aesthetic outcomes, preoperative and final photographs of each patient were reviewed by 3 other plastic surgeons and 4 laypersons. For comparison, 6 other patients who were treated with conventional surgery during the same period were reviewed. After final reconstruction surgery, the authors surveyed patients’ satisfaction via telephone.

Results: Six patients were followed up for an average of 87.66 months (range, 55–123 months). The mean number of tissue expander insertions was 3.33 and the mean number of total expanders inserted was 4.83. Complication associated with expander exposure occurred in 1 patient during the fifth expansion. The average score of aesthetic outcome in the multiple reexpansion group was superior to that of the conventional group (2.60 versus 2.10, P = 0.03). During the telephone survey, patients did not rate their appearance as positive, although they were comparatively satisfied with the surgical procedure.

Conclusion: Considering the low rate of malignancy involving congenital melanocytic nevus in childhood, multiple reexpansion is an attractive option to obtain better results compared with other reconstructive methods.
