Treatment of congenital facial nevi.

The treatment of congenital facial nevi is often difficult and challenging. Previous authors have reported their techniques, results, and complications when treating these lesions. Our objectives are to simplify the treatment planning by subdividing the lesions with a new classification and using this to formulate a surgical algorithm. One hundred and two patients with congenital facial nevi were reviewed. All of these patients have had surgical excision for the lesions. We have subgrouped the lesions into three groups, according to size, number of aesthetic units involved, and number of reconstructive stages required. Group I included lesions 1 to 3 cm in maximal diameter, within one aesthetic unit, and requiring one or two reconstructive stages. This group included 29 patients. Group II included lesions 3 to 12 cm in maximal diameter, covering one or two aesthetic units, and requiring not more than two stages of reconstruction. This group had 41 patients. Group III consisted of extensive lesions, over 12 cm in maximal diameter, covering several aesthetic units, and requiring several stages of reconstruction. In this group, we had 32 patients. On the basis of our experience in treating congenital facial nevi in this series, we have developed a surgical algorithm for reconstruction. We are optimistic that this will assist the surgeon in surgical planning and treating this complex patient population. The algorithm is arranged according to the new classification of congenital facial nevi that is presented.
