Vascular lip enlargement: Part II. Port-wine macrocheilia--tenets of therapy based on normative values.

Port-wine (capillary) vascular malformations that enlarge the lips (port-wine macrocheilia) are challenging reconstructive problems which, as a result, often go untreated. The surgical management of these lesions is not straightforward. Scarification by laser to diminish the discoloration has been performed with good results in some cases. However, laser treatment does little to correct three-dimensional tissue deformities such as macrocheilia, which must be addressed surgically. We present our experience with the treatment of port-wine macrocheilia in 11 patients over the 10-year period between 1983 and 1994. Basic principles for surgical and nonsurgical treatment of these patients are also discussed. Normative data about lip dimensions are important to surgical planning. We used 40 male and female volunteers, all less than 30 years of age, as a source for measuring normal lip dimensions, thereby creating a normative database. Preestablished points in the labial and perioral region were marked. Measurements were taken and then averaged. This information was used as a guide for surgical excision of large defects in some patients. In addition, in both the lower and the upper lip, if the opposite side is uninvolved, this database could serve as a template for reconstruction of the affected side. Between 1983 and 1994, 11 patients underwent surgery for port-wine macrocheilia. Of the 11 patients, 1 had previous treatment consisting of laser scarification. Four patients had port-wine vascular malformations involving the upper lip alone, four involved the lower lip alone, and three involved both lips. In six patients, other areas of the face and body were also involved. Our experience has led us to perform earlier surgical intervention than has previously been described for these patients. Basic reconstructive surgical principles and planning based on normative data and templates can lead to excellent results.
