A case of reconstruction with deltopectoral flap and labioplasty performed against buccal cancer is reported. Histopathologically, the tumor was a squamous cell carcinoma which infiltrated into the region just before muscularis mucosae. Radiotherapy and chemotherapy were performed prior to epauxesiectomy including buccal skin. Deltopectoral flap was used as double layers, folded at the apex of flap, and deepithelization was performed at the folded site for preventing oro-extra fistula. The flp tip was sutured at the mandibular side and the deepithelized area was sutured at the maxillary side. Four weeks later, the flap was cut off with fevorable prognosis. Howeve, because of doubled flap, trismus occurred and the dental prothesis failed to prepare. Labioplashy with normal lingual mucosal flap and commissuroplasty with double Z plasty (Mays method) were thus performed for improving trismus. In consequence, a preparation of dental prothesis become possible.
