Mucoepidermoid Carcinoma in the Orifice of the Eustachian Tube; A Case Report

Mucoepidermoid carcinoma involving the nasopharynx is very rare. A mucoepidermoid carcinoma in the orifice of the eustachian tube of a 66-year-old male was excised with contact YAG laser through a transpalatine approach. The tumor was clearly demarcated and localized within a limited area in the nasopharynx, but radical removal with an adequate margin of safety through a transpalatine approach was very difficult because of the limited field of vision. The development of mucoepidermoid carcinoma from minor salivary glands and surgical treatment of the malignant tumor in the nasopharynx are discussed.
