Facial Artery Musculomucosal Flap in Alveolar Cleft Surgery

Introduction:Large anterior palatal fistula and special alveolar clefts, such as edentulous atrophic premaxilla and absent premaxilla (premaxillectomy or agenesis), as well as wide unilateral alveolar cleft, are complicated cases in alveolar cleft bone grafting surgery. A superiorly-based buccinator myomucosal flap is suitable in this regard. Materials and Methods:The cleft patients whose large anterior palatal fistula and superiorly based buccinator myomucosal flap had been used for palatal or alveolar reconstruction were recruited in the study. The reconstruction method of the nasal floor, follow-up time, and hospital length of stay were recorded. Results:A total of ۱۰ patients had been treated by this method. The majority of them were male (۶/۱۰), the age range of the patients was ۱۴-۲۵ years. All flaps survived and a case of partial necrosis occurred. Conclusion:As evidenced by the obtained results, a superiorly-based facial artery musculomucosal flap is suitable when the palatal fistula is continuous with the alveolar cleft. Transmaxillary transfer is the other option in patients with closed maxillary arch.
