          Summary:

          Closure of huge palatal fistula surrounded by fully erupted permanent dentition in the adult patients with cleft is a challenge. Posteriorly based buccinator myomucosal flap is a neurovascular pedicled flap, with inherent nature of thin thickness, saliva secretion, and axial pattern blood supply. Vicinity of donor site to the palate and low donor-site morbidity are the other advantages. It is an ideal choice in such situation. In this article, the details of surgical technique and the effectiveness of this method are presented.

          A new intraoral flap: facial artery musculomucosal (FAMM) flap.

          By combining the principles of nasolabial and buccal mucosal flaps, we have designed a new axial musculomucosal flap based on the facial artery. This flap has been designated the facial artery musculomucosal (FAMM) flap. The flap has proven to be reliable either superiorly based (retrograde flow) or inferiorly based (antegrade flow). It is versatile and has been used 18 times in 15 patients, with one failure and two partial losses. It has been used successfully to reconstruct a wide variety of difficult oronasal mucosal defects, including defects of the palate, alveolus, nasal septum, antrum, upper and lower lips, floor of the mouth, and soft palate.

            The buccinator musculomucosal flap: anatomic study and clinical application.

            Since 1984, we have used the buccinator muscle mucosal flap for the treatment of mucosal defects after tumor resection, osteomyelitis of the mandible, closure of cleft palate fistulas, primary closure of very wide cleft palates, and lengthening of the soft palate. A study was made in the facial regions of 14 cadavers, and a comparison was made to descriptions found in the anatomic literature. It was confirmed in our dissections that the buccal artery, which reaches the posterior half of the muscle, is the major arterial pedicle of the buccinator and that it runs very close to the buccal nerve. Several veins originating from the lateral aspect of the muscle make the venous drainage of the buccinator even richer than its arterial supply. The abundant vascular supply from multiple interconnected pedicles supports the blood supply of the buccal mucosa. The motor innervation of the buccinator muscle comes from the facial nerve. The buccinator is considered to be a part of the sphincteric muscular system involving the functions of sucking, whistling, propelling food during mastication, and voiding the buccal cavity. The flap was utilized clinically in 38 patients: 24 to close primary cleft palates that required palate lengthening, 12 to close palatal fistulas, 1 to treat a mandibular osteitis, and 1 to repair the palate after tumor resection. We had three small fistulas as complications in our series owing to technical mistakes.

              Role of free-tissue transfer in the treatment of recalcitrant palatal fistulae among patients with cleft palates.

              Recurrent palatal fistulae present a particularly vexing problem for patients with cleft lips and palates and their surgeons. When primary closure fails, conventional wisdom and the standard of care suggest local flap techniques for defect closure. For the large majority of patients, this approach is successful. There is, however, a small subset of patients who undergo multiple surgical procedures in unsuccessful attempts to close recalcitrant fistulae, particularly at the anterior, densely scarred, hard palate. In this setting, repair calls for the introduction of well-vascularized pliable tissue to close the defect and to avoid hampering further palatal growth. Local muscle flaps and oral axial pattern flaps have been advocated and used successfully. However, those approaches have their own drawbacks, such as multiple surgical interventions, patient compliance, and intraoral scarring. In an effort to avoid the problems associated with local flaps, distant microvascular tissue transfers were investigated. During a 6-year period, six free-tissue transfers were performed as a primary means of treating recalcitrant palatal fistulae. Three dorsalis pedis flaps and three osseous angular scapular flaps were used. The conditions of all patients improved, with five patients achieving complete long-term closure of the palatal defect. This experience indicates that modern microvascular techniques have reached a level of success commensurate with that of other flap techniques; therefore, it is concluded that free-tissue transfer should be considered as a primary means of addressing these difficult cleft problems.
