A tale of 1 year: a case of bilateral conductive hearing loss due to bilateral ossicular chain disruption post head trauma

Abstract

The traumatic hearing loss is a common finding after head trauma that involves the temporal bone fracture or skull base injury, but the late presentation of the hearing loss bilaterally is a rare presentation. This case report describes the rare and late presentation of bilateral conductive hearing loss 1-year after the head trauma, limited to ossicular chain disruption and hearing loss. This case of post head trauma that was limited to ossicular chain distribution progressed to bilateral conductive hearing loss without temporal bone fracture. A 14-year-old male was presented conductive hearing loss of one year after head injury, CT scan revealed bilateral ossicles disruption. Afterwards, osicuoloplasty was performed which improved the hearing of the patient. In conclusion, bilateral hearing loss with no obvious skull fracture should be suspected and investigated so an early intervention could be established. The CT was considered the imaging modality of choice for ossicular chain distribution.
