Abstract
Objective:
An anterior hard palate fistula for which more than one attempt at repair using local tissue has failed is a difficult complication in cleft surgery. Prior to alveolar bone grafting, cleft patients have an open anterior maxillary arch that allows passage of a pedicled flap from cheek to hard palate. The superiorly based facial artery musculomucosal flap passed through the clefted alveolus is one of the newer techniques to solve this difficult problem. The aim of this study was to assess the validity of using a facial artery musculomucosal flap with an anterosuperiorly based pedicle with retrograde blood flow to repair a large anterior hard palate fistula when a lack of adequate local soft tissue precludes a local flap closure and the patient otherwise would need a tongue flap.
Results:
Of 16 facial artery musculomucosal flaps in 14 children, 12 were successful, 2 suffered partial flap loss secondary to venous congestion, and 2 had complete flap failure. One had a small wound dehiscence that resulted in a small posterior fistula.
Conclusion:
An anterosuperiorly based facial artery musculomucosal flap is a viable option to close large anterior hard palate defects. Care needs to be taken to ensure adequate venous drainage. This flap obviates the need for a staged tongue flap repair for those patients with an open maxillary arch.
