Abstract

We report two cases of nasopharyngeal carcinoma resected by endoscopic nasopharyngectomy （ENPG）. The first case was a 62-year-old man with rT1 squamous cell carcinoma after radiotherapy. Transpalatal ENPG was selected because the tumors were confined to the median position of the postero-superior wall in the nasopharynx. No local recurrence was observed, though wound healing was delayed. The second case was a 92-year-old woman with T1 adenocarcinoma. Transnasal ENPG was selected because the tumors were confined to the superficial position of the lateral wall in the nasopharynx. The wound was covered with a free mucosal flap, resulting in good wound healing. No recurrence has been observed to date. ENPG for nasopharyngeal carcinoma with radioresistant histology and local recurrence after radiotherapy is considered to be a useful option that enables minimally invasive resection with a good visual field.
