A case of mandibular reconstruction with clavicle is presented. A 54-year old woman, who received irradiation for therapy of buccal cancer, visited our clinic complaining of exposed bone at premolar area. This lesion has become oro-cutaneous fistula with bone necrosis within a few years in spite of minor sequestrectomies. Necrosed mandibular body was, therefore, resected about 5 cm in length. Seven months after this treatment, splitthickness of clavicle was used with sternocleidomastoid muscle as an osteomascular flap. Skin graft vestibuloplasty was done one year after success of mandibular reconstruction. Denture is well-fitted and stable on improved alveolar rigde.
