Multiple complications due to osteoradionecrosis in a patient with thromboangiitis obliterans.
A case is presented of a patient with thromboangiitis obliterans (TAO) who developed severe necrosis of the intraoral soft tissues and maxillary and mandibular bone after radiotherapy for a cT2N0M0 squamous cell carcinoma of the soft palate. Multiple surgical procedures including partial resection of the mandible and maxilla and reconstruction of intraoral and extraoral defects with a pectoralis major myocutaneous flap and anterolateral thigh flap were performed with partial success. Although a causal relationship between TAO and the described complications cannot be verified, close monitoring of patients with TAO who are being treated with radiotherapy is advised.
