A novel technique for cheek mucosa defect reconstruction using a pedicled buccal fat pad and buccinator myomucosal island flap

Summary 

Reconstruction of cheek mucosa defects following tumor resections can be approached with several techniques, depending on size of the defect. Fasciocutaneous and perforators free flaps are widely employed today for such reconstructions. However, small defects or general health of the patient may limit their indications. Furthermore, approaching moderate size defects, some techniques, like temporalis muscle or fascia pedicled flaps, lead to contracture with limitation of mouth opening or trisma, and others, like intraoral local flaps, do not provide enough tissue for the reconstructions. In this work the authors propose, for reconstructing these kind of defects, the use of a buccinator myomucosal island flap and a buccal fat pad pedicled flap association. A case is reported and the surgical technique is explained. This new reconstructive technique can easily be used for reconstructing moderate-sized cheek defects, achieving optimal results: the internal mucosal lining is restored in few weeks without any retraction, contracture, of scars on the face limiting the aesthetic outcome and mouth opening.
