We present a rare case of radionecrosis of the hypopharynx and subsequent descending necrotizing mediastinitis after radiotherapy for T2 laryngeal carcinoma. A fiberoptic examination revealed massive necrosis in the hypopharynx without intralaryngeal abnormalities. In spite of the medical treatment,his conditions were deteriorated. A computed tomography showed extensive air density areas from the retropharynx to the mediastinum. Transcervical and subxiphoid drainage surgery led to success in controlling the infection. However,total pharyngolaryngectomy and reconstruction with free jejunal transfer were necessitated to resume the oral intake because the necrotizing infection resulted in irreversible total mucosal defects of the hypopharyngeal wall.
