Adult previously operated alveolar cleft palate presents a pronounced challenge for optimal surgical reconstruction. This optimal reconstruction dictates the restoration of soft tissues in addition to hard tissues to achieve prime functional results. Regional flaps usually used for the reconstruction of such defects were considered as either bulky or none bone bearing flaps. Furthermore, using free flaps for reconstruction can rise the concerns of increased intraoperative complications and greater suspected donor site morbidities. Here we present three unfavorably previously operated patients with current huge alveolar cleft palates, planned for the reconstruction with reverse facial-submental artery osteomyocutaneous flap. Besides, detailed flap harvesting technique, results, prosthetic restoration post to flap surgery, and follow up are presented in this article. We found the reverse facial- submental osteomyocutaneous flap as a novel and reliable choice for functional reconstruction of challenging huge alveolar cleft palates. The reverse facial-submental flap has not been yet mentioned in the medical literature for the reconstruction of alveolar clefts.
