Dilemmas in Diagnosis and Management of Temporal Bone Fractures and Their Sequelae

Objective(s): The objective of this study was to report our experience with a series of patients with temporal bone fractures from 2019 to 2023 and to evaluate the dilemmas in diagnosing the extent of their ontological injuries through a narrative review of the literature focusing on the classifications of temporal bone fractures. Methods: Data were collected retrospectively from the electronic medical records of patients who presented to the emergency department and were diagnosed with temporal bone fractures using computed tomograms of the head and temporal bone between September 2019 and March 2023. A total of 117 patients were included in the study. Demographic data, fracture classification, mechanism of injury, and presence and/or repair of cerebrospinal fluid (CSF) leak, facial nerve injury (both immediate and delayed), and hearing loss (both immediate and delayed) were also recorded. Results: In total, 49.5% of our cohort were between the ages of 19 and 39, and the majority (66%) were males. The primary cause of the trauma was falls in 41% of patients, followed by motor vehicle accidents (29%), and 70% had a Glasgow Coma Score (GCS) between 13 and 15 at presentation. In total, 92.3% of temporal bone fractures did not involve the otic capsule, and 79.3% were longitudinal fractures. In total, 89% of the CSF leaks were seen in patients with longitudinal fractures. Similarly, 70% of facial nerve deficits were seen in patients with longitudinal and otic capsule-sparing fractures. Conclusion: Diagnosis of facial asymmetry and hearing loss in patients with TBFs can be challenging in acute care settings but was less challenging in our cohort due to patients presenting with good GCSs. Dilemmas in clinical evaluation in the acute care setting are due to poor GCSs, heterogeneity of documentation of injuries, and classification of TBFs. Implementation of universal protocols with homogeneity in the documentation and classification of temporal bone fractures may help improve patient care and prediction of outcomes.
