Primary eustachian tube tuberculosis

Abstract

Nasopharyngeal tuberculosis is a rare occurrence, and primarily involves the proximal part of the Eustachian tube. Mechanical obstruction of the Eustachian tube will affect the pressure discre-pancy between the middle ear and the external atmosphere, leading to aural fullness, unilateral hearing disturbance, and otitis media. These conditions can be overlooked or mistakenly diagnosed as ear pathology. We report a case of unilateral hearing loss and tinnitus in a 31-year-old healthy woman that was later confirmed to be tuberculosis of the Eustachian tube. In cases with indicators suggesting a high index of suspicion, a thorough examination of the head and neck regions is especially very important. Once it has been diagnosed, Eustachian tuberculosis can be successfully treated with anti-tuberculosis medications.
