ABSTRACT
Satisfactory and consistent long-term results in primary and secondary rhinoplasty rely on adequately resupporting or reconstructing the nasal osseocartilagenous framework. Autogenous rib cartilage has been our graft material of choice for major nasal reconstruction when sufficient septal cartilage is not available. The rib provides the most abundant source of cartilage for graft fabrication and is the most reliable when structural support is needed.

OBJECTIVES: To describe the split orbicularis myomucosal flap and to review our center's experience with this technique for large defects of the lower lip. METHODS: All patients presenting to the senior author (Y.D.) for lower lip reconstruction using this flap were reviewed in a retrospective fashion. RESULTS: A total of 14 patients with a minimum follow-up of 6 months (mean, 3.4 years; range, 6 months to 5 years) underwent lower lip reconstruction using the split orbicularis myomucosal flap from May 1999 to May 2004. Twelve of the defects arose as a result of cancer resection (squamous cell carcinoma [n = 8], basal cell carcinoma [n = 3], and melanoma [n = 1]), and 2 arose secondary to trauma. The defect crossed the vermilion in two thirds of the cases, extending for a variable distance onto the cutaneous portion of the lower lip. The defect size varied from 50% to 80% of the transverse dimension of the lower lip (mean, 68%) and involved the commissure in 4 patients. There were no flap failures, facial nerve palsies or paralyses, oral incompetence, or need for scar revision in any of our study population. CONCLUSION: The split orbicularis myomucosal flap is a reliable method of reconstructing significant defects of up to 80% of the lower lip with minimal risks of microstomia or functional impairment.
