A patient was referred by her dentist to the author for the evaluation of a left palatal mass and orofacial anesthesia. The author diagnosed a maxillary sinus malignancy and anesthesia of the maxillary branch of the left trigeminal nerve. Thoroughly examining the maxillary sinus of each patient who has anesthesia of the maxillary branch of the left trigeminal nerve is important in the early detection of adenoid cystic carcinoma.
