Abstract： Objective:To explore the diagnosis, treatment and aeromedical assessment of parotid pleomorphic adenoma for civil pilot.Methods:The diagnosis, treatment and aeromedical assessment of a class I pilot with parotid pleomorphic adenoma were analyzed. Related literatures were reviewed.Results:The 54-year-old male pilot was found a mass behind the right earlobe in the routine annual physical examination. B-ultrasound examination showed solid nodule in the right parotid gland. The mass and superficial parotid glands were removed and the facial nerve was dissected. Pathology showed pleomorphic adenoma of the right parotid gland. No complications were found in physical examination 2 months after the operation. The masticatory function and facial nerve function were good and CT showed no obvious abnormalities. The pilot was finally qualified for flying. No tumor recurrence or other complications were found 5 months after returning flight. B-ultrasound showed changes after partial resection of the right parotid gland and no other abnormalities were found.Conclusions:Parotid pleomorphic adenoma may be ignored easily at its early stage. The pilot with proper treatment and good postoperative recovery can be qualified to flight.
