Application of Indocyanine Green Angiography for Perfusion Assessment of Buccal Myomucosal Flaps.

ABSTRACT: The indications for buccal myomucosal flaps (BMMFs) include velopharyngeal insufficiency (VPI) and palatal fistula. A major complication related to BMMF is partial flap necrosis due to its random blood supply. Indocyanine green (ICG) angiography is a proven technology to assess tissue perfusion, but there is limited report of its application to intraoral flaps, especially in cleft surgery. Two patients underwent BMMF for repair of palatal fistula and treatment of VPI. ICG angiography was performed to assess flap perfusion after flap elevation and again after flap inset. Patients were followed up for flap healing and speech assessments. In the first patient, ICG angiography confirmed excellent perfusion to both flaps after elevation and inset. In contrast, after elevation of bilateral BMMF
