PurposeVascular lip anomalies include infantile hemangiomas, venous malformations, and arteriovenous malformations. Surgical management can be complicated by alterations in horizontal length, vertical height, and lip thickness from the underlying pathology. Additional reconstructive challenges include preservation of oral continence, vermillion definition, and the sublabial sulcus. This report describes a technique of supramaximal single-stage full-thickness wedge resection of these lesions.Materials and MethodsA retrospective study approved by the institutional review board of patients who underwent full-thickness resection of vascular lip anomalies from December 2007 through February 2013 was performed. Patient demographics, final diagnosis, preoperative treatment, examination findings (pre- and postoperative), intraoperative management, and follow-up findings were reviewed.ResultsEighteen patients (9 female) with a mean age of 25 ± 19.8 years (range, 3 to 70 yr) were identified. Underlying pathologies were arteriovenous malformation (6), port wine stain with secondary soft tissue hypertrophy (6), capillary malformation (1), venous malformation (3), and infantile hemangioma (2). Prior treatments included embolization, lasers, surgical excision, steroids, and propranolol; 8 patients were treatment naive. All patients underwent a single or double pentagonal-shaped wedge resection of the involved upper or lower lip. An average of 3.75 cm (41.7%; range, 20 to 70%) of horizontal lip length was excised. Four patients required additional concomitant debulking of the vermillion. No intraoperative complications were noted. Postoperatively, 1 patient developed wound dehiscence at 12 days and another had a midline depression with mild oral incontinence. Follow-up averaged 1,074 days (range, 371 to 1,777 days) and patients and their parents reported a high degree of satisfaction with the improvement in lip appearance and symmetry except for 1 patient who required further debulking. The sublabial sulcus and vermillion and cutaneous definition were preserved in all cases.ConclusionDespite the traditional recommendation that no more than 30% of lip length be surgically removed, vascular lip anomalies result in tissue hypertrophy, horizontal elongation, ectropion labii, and tissue expansion that allow up to 70% of the lip to be excised.
