Abstract

External auditory canal (EAC) trauma, although rare, can have significant long-term adverse outcomes. This study aims to investigate the frequency, treatment, and complications of external ear canal injury in association with mandibular and temporal bone trauma. Retrospective chart review. Computed tomography images with mandibular or temporal bone trauma were reviewed for EAC fractures. Patient data were collected from initial presentation and subsequent follow-up clinic visits. Thirty-nine percent of temporal bone fractures and 3.3% of mandible trauma involved the EAC. In particular, 10% of condylar or subcondylar trauma included an EAC fracture (P = 0.0006). One patient sustained bilateral EAC fractures despite an isolated, unilateral condylar fracture. The most common presenting sign was blood in the external auditory canal. Two patients underwent exam under anesthesia and removal of debris and stenting as treatment, whereas 42% of the patients were placed on otic drops and 5% received packing or a stent. Follow-up data were only available for 16% of the patients. Hearing loss from otic capsule involvement or ossicular chain disruption were follow-up complaints, and one patient had persistent canal stenosis. External audito...Continue Reading
