BACKGROUND Reconstruction of moderate-sized mucosal defects of the oral cavity or oropharynx represents a surgical challenge. Buccinator myomucosal flaps seem to provide "ideal reconstruction" of oral/oropharyngeal defects because they carry a thin, mobile, well-vascularized, and sensitive tissue, like that excised or lost. Nevertheless, these flaps are not immediately popular because of confusion surrounding the complex terminology used to name them. METHODS After a retrospective study on our experience and a literature review, the authors propose a new rational and simplified nomenclature for the classification of buccinator myomucosal flaps, which clarifies the source vessel, the composition of the flap, and the type of transfer. RESULTS According to this nomenclature, six types of buccinator myomucosal flaps are described. CONCLUSIONS This proposed nomenclature may bring a consensus on the classification of buccinator myomucosal flaps and can help their spread.
