Highlights
- •Persistent posttraumatic hearing loss may be due to ossicular chain disruption.
- •Malalignment of the middle ear ossicles is associated with conductive hearing loss.
- •Ossicular injury is more often seen with longitudinal temporal bone fractures.
- •Ossiculoplasty is the definitive surgical treatment.
Abstract
Traumatic head injuries can be associated with ossicular chain disruption. Especially
in the setting of temporal bone fractures, proper alignment of the ossicular chain
has to be insured. Loss of normal ossicular alignment is associated with conductive
hearing loss. Treatment of ossicular chain disruption, so called ossiculoplasty, aims
to restore proper anatomic alignment of the ossicles with osseous or cartilaginous
autograft and/or prosthetic devices.
