Abstract Background/Aims There is a paucity of literature on external auditory canal ( EAC ) fractures secondary to maxillofacial trauma, with most of the literature on EAC fractures consisting of isolated case reports. To the authors’ best knowledge, this is the first study to use cone beam computed tomography to evaluate the EAC region. The aim of this study was to assess the prevalence of external auditory canal ( EAC ) fracture following maxillofacial trauma and to evaluate the association between EAC fracture and other maxillofacial fractures and the region of trauma. Materials and Methods One hundred patients were prospectively evaluated over 6 months from February to August 2016. The patients were referred for CBCT regarding temporomandibular joint or condylar fractures following maxillofacial trauma. Two observers (both experienced radiologists) assessed the EAC and associated fractures in the maxillofacial region. Results External auditory canal (EAC) fracture was confirmed in 32% of the patients. Of the EAC fractures, 68.75% and 31.25% were associated with mandibular fractures and non‐mandibular fractures, respectively. Of the EAC fractures, 68.75% were single fractures and 31.25% of patients had multiple comminuted fractures. Significant association was observed on cross‐tabulation of the fractured region and region of trauma with the presence of EAC fracture using chi‐square test. Conclusion External auditory canal ( EAC ) fracture is associated with maxillofacial fractures with increased incidence in mandibular fractures compared to non‐mandibular fractures.
