Kim AS, Betz JF, Goman AM, et al. - A nationally representative cross-sectional sample was combined with census data to approximate population estimates of obstructive eustachian tube dysfunction (OETD) among US adolescents to further understand the burden of OETD over the life course. OETD affects over 11 million adults in the US and is related to chronic suppurative otitis media, middle ear atelectasis, and tympanic membrane perforation. Children are at higher risk of obstruction and reflux of nasopharyngeal secretions and pathogens compared with adults, resulting in higher cholesteatoma recurrence rates and poorer hearing outcomes after surgery.
