Mucomuscular Elastic Flap for Lower Lip Vermilion Reconstruction: Experience in a Series of Cases in Pediatric Patients

The mucocutaneous line and the lip vermilion are important structures from an esthetic standpoint but also in relation to the functionality of the mouth. In the literature, several types of flaps have been described for reparation of labial defects in adults. In this study, the authors analyze results of surgical reconstruction of the lower lip in the pediatric population using unilateral or bilateral mucomuscular elastic flaps for labial reconstruction. A retrospective analysis of 10 patients operated between 2003 and 2018 at our institution was made. The following demographic and clinical data were collected: age, sex, diagnosis, type of flap, follow-up, results, and complications. The Strasser scale was chosen for assessment of postoperative photographic results. Average age was 8.1 years (range 3-18). The most frequent etiology was arteriovenous malformation seen in 60% of cases. All cases corresponded to a defect of the lower lip. The average percentage of lip compromised was 44% and the largest length of compromise observed was 60% of the lip. Follow-up was on average 2.4 years. Esthetic results according to the Strasser method were as follows: 1 patient presented an excellent esthetic result, 5 good, 4 regular, and 0 poor. Considering the esthetic outcomes and low incidence of complications of the mucomuscular elastic flap, it is an acceptable and recommended technique of choice for lip vermilion reconstruction.
