Successful surgical treatment of a solitary parapharyngeal metastasis from thyroid cancer, using the mandibular swing-transcervical approach: report of a case.

A 72-year-old man presented with a right parapharyngeal mass, 4 cm in diameter, which was subsequently diagnosed as a metastasis originating from papillary carcinoma of the thyroid gland. The parapharyngeal tumor was successfully removed by the mandibular swing-transcervical approach with pharyngeal reconstruction, performed using a buccal mucosal island flap based on the facial artery. His postoperative course was uneventful, and the preoperative clinical symptoms such as dysphagia and headaches completely resolved after surgery.
