Background: Surgeons have long been concerned with the optimal tissue replacement of resected or damaged oral mucosa. Managing the intraoral soft tissue defects can be achieved with specially constructed fasciocutaneous, myocutaneous, and muscle flaps. It is physiologically ideal to replace mucosa with the same type of tissue. Buccinator-based myomucosal flaps are ideal for fixing medium-sized mucosal defects inside the mouth because they are well-supplied with blood, sufficiently thick, have a large mucosal paddle, and release saliva. We intended to outline an overview about Buccinator Myo-mucosal flap (BMMF), vascular basis and technique.

Conclusion: The BMMF can be created using a variety of methods. A posterior, anterior, or superior base for the BMMF is possible. An island flap is generated by isolating the pedicle; this allows for better rotation; and a "buccinator myomucosal neurovascular island pedicle flap" is formed using the buccal venous plexus, the buccal artery, as well as the nerves that innervate the muscle; these are modifications to the original operation. Buccinator myomucosal flap had minimal donor site morbidity and short hospital stays. The BMMF has many benefits, such as a large supply of tissue, the ability to use the same tissue to replace damaged or missing mucosa, a decreased risk of infection at the donor site, and the best possible cosmetic and functional outcomes.
