AbstractTraumatic conductive hearing loss (TCHL) is most commonly attributed to tympanic membrane perforations, hemotympanum, or ossicular chain disruption. These complications are generally managed conservatively for up to 6 months with good hearing outcomes. We encountered a case of penetrating facial trauma leading to TCHL because of obstructive Eustachian tube dysfunction (OETD), which is not a previously described etiology for OETD and TCHL. A lysis of scar tissue surrounding the Eustachian tube with balloon dilation was performed in our patient, resulting in resolution of conductive hearing loss. In the absence of traditional signs of TCHL, providers should consider OETD as a potential cause of TCHL. We recommend visualization of the Eustachian tube orifice and balloon dilation if clinically indicated.Published by Oxford University Press on behalf of the Association of Military Surgeons of the United States 2023.
