Abstract

PURPOSE
The Abbe flap procedure has been used to correct disharmony of the upper and lower lips as well as for making a philtrum for patients with secondary cleft lip deformities. But the Abbe flap procedure adds two scars in addition to the prior operative scar on the upper lip. This study was conducted to determine the treatment outcomes of esthetic subunit excision of the scar on the philtrum and Abbe flap coverage for correction of cleft lip deformities with photogrammetric analysis. METHODS: This study investigated a total of 11 patients with cleft lip deformities who underwent scar excision with Abbe flap coverage, and the patients were followed up for at least 6 months. Under general anesthesia, a mushroom- shaped Abbe flap was drawn on the lower lip with a width of 8 mm and a height 1~2mm longer than that of the philtral midline. The epidermis and dermis of the scar on the upper lip were excised. In the cases with alar base depression, the orbicularis oris muscle was split vertically and transposed to the alar base. The Abbe flap was harvested as a pedicled flap containing a small amount of muscle and this was rotated 180-degree to be inserted into the upper lip. Mucosa, muscle, subcutaneous tissue and skin were closed in layers. The flap was divided at the 7~14 postoperative day. The postoperative outcomes were evaluated by using photogrammetric analysis. Three indices were measured from the standard clinical photographs taken before and after the surgery. For anthroposcopic assessment, observers described the postoperative outcomes using an ordinary scale method.
RESULTS
The postoperative values obtained in the photogrammetric analysis showed improvement as compared with the preoperative ones. Improved anthroposcopic outcomes were also noted.
CONCLUSION
Scar excision and Abbe flap coverage were proven to be effective in improving protrusion and the height of the upper lip, the scar of the upper lip and the symmetry of Cupid's bow and the philtral column, as well as formation of the philtral dimple.
