Myomucosal island flap in the reconstruction of oral cavity defects: Description of the surgical technique

Abstract

Multiple options are available for the reconstruction of the defects of the oral cavity. Among these, the facial artery myomucosal island flap (FAMMIF) is a pedicled flap composed by cheek mucosa, submucosa, and part of the buccinator muscle. The FAMMIF is ideal for the reconstruction of small-to-moderate defects of the oral cavity and the oropharynx. This is due to low operating time, low morbidity, and good functional and aesthetic results. A step-by-step description of the flap harvesting is presented, with particular attention to flap design, identification of the vessels, harvesting of the myomucosal island, tunnel preparation for its passage in the neck and back to the oral cavity, and closure of the cheek donor site with the buccal fat pad.
