Qualification of Pilots with Aero-Otitis Media After Balloon Eustachian Tuboplasty

Abstract

BACKGROUND: Aero-otitis media (AOM), also known as aural barotrauma or barotitis media, is categorized into primary AOM and secondary AOM. Because conservative treatment was ineffective, primary AOM was one of the main reasons for grounding. In 2014, the team successfully treated a pilot with primary AOM using balloon Eustachian tuboplasty (BET). Now, this case is reported.CASE REPORT:The patient was a 40-yr-old male transport pilot who joined a flight after catching a cold. During the descent, the right ear appeared to have stuffiness and hearing loss, accompanied by tinnitus and ear pain. The local hospital’s acoustic immittance test showed an “A” curve in the left ear and a “B” curve in the right ear. According to “secretory otitis media”, right tympanic membrane puncture and drugs were performed. After he recovered, he continued to fly, and the symptoms reappeared again. Then he was transferred to our hospital, and right BET was performed. Equalization of ear pressure in the hypobaric chamber returned to normal 2 mo after the operation. The pilot was found fit to fly. The pilot is still qualified, with more than 6000 h of flight time.DISCUSSION: AOM is linked to Eustachian tube dysfunction. BET has been a minimally invasive treatment of Eustachian tube lesions in recent years. If conservative treatments for primary AOM are ineffective, BET can be selected. While the postoperative symptoms disappeared, pure tone audiometry, tympanometry, and ear pressure function tests met the standards for the physical examination of pilots, allowing the determination of flight qualification.Zhang M, Liu X, Wang B, Jin Z, Xu X.
