Utility of J-Shaped Scar Tissue-Based Flap for Secondary Bilateral Cleft Lip Repair: A One-Stage Procedure with Successful Outcomes on Correction of Vermilion Border, Volume Deficiency of Lip, and Muscular Function.

Abstract

This study aimed to evaluate the utility of J: -shaped scar-tissue-based flap as a new technique in secondary bilateral cleft lip reconstruction in patients with challenging secondary deformities. A total of 52 patients, comprising 38 males and 14 females with a mean age of 21.0 years (range: 16-42 years), who underwent secondary bilateral cleft lip repair operation via the J: -shaped scar tissue flap technique in our clinic between 2014 and 2019 were included. Postoperatively, patients were followed up for an average of 2 years (range, 6 months to 5 years) to assess the outcomes regarding vermilion border, philtrum symmetry, function of the orbicularis muscle, and lip volumetric symmetry, based on the Global Aesthetic Improvement Scale (GAIS), patient-reported outcomes, and independent plastic surgeons' examinations. After an average follow-up of 2 years, outcomes regarding vermilion border, philtrum symmetry, function of the orbicularis muscle, and lip volumetric symmetry were successful, and none of the patients experienced new notch formation, muscular functional loss, lip volume loss, or asymmetry. Owing to good muscular function preventing the stretching, the postoperative scars become more acceptable to the patients. The technique has proven to be safe and successful through the GAIS objective assessment, as also confirmed by the examinations of the three independent surgeons, while the majority of patients reported an exceptional improvement in the appearance alongside a more than 95% satisfaction rate with the operation. In conclusion, our findings revealed successful functional and aesthetic outcome of using J: -shaped scar tissue flaps in secondary repair of cleft lips. The technique was associated not only with the correction of significant secondary deformities yielding an improved and symmetrical lip volume, correction of vermilion notch, and prevention of notch re-formation but also with the restoration of orbicularis oris muscle function and thus integrity of the lip with minimal scarring.
