    High-resolution computed tomography (CT) effectively identified temporal bone trauma, including ossicular chain disruption and fractures, in patients with hearing loss and facial nerve issues. CT findings guided surgical planning and improved patient care by revealing expected abnormalities.

    Area of Science:

    • Radiology
    • Otolaryngology
    • Trauma Surgery

    Background:

    • Temporal bone trauma can lead to significant hearing loss and facial nerve dysfunction.
    • Accurate diagnosis of temporal bone fractures and ossicular chain injuries is crucial for effective management.
    • Conventional imaging may not always provide sufficient detail for complex temporal bone pathologies.

    Purpose of the Study:

    • To evaluate the utility of high-resolution computed tomography (CT) in diagnosing temporal bone trauma.
    • To correlate CT findings with clinical presentations and surgical outcomes.
    • To assess the impact of CT imaging on surgical planning and patient care.

    Main Methods:

    • High-resolution computed tomography (CT) was performed on 12 patients with suspected temporal bone trauma.

  • CT results were compared with clinical signs and symptoms, including hearing loss and facial nerve dysfunction.
  • Operative findings from 5 surgically treated patients were correlated with preoperative CT scans.
  • Main Results:

    • High-resolution CT accurately identified ossicular chain disruption and fractures in the majority of patients.
    • CT findings correlated well with the clinical manifestations of hearing loss and facial nerve dysfunction.
    • Preoperative CT scans alerted surgeons to specific abnormalities, aiding in surgical planning.

    Conclusions:

    • High-resolution CT is a valuable tool for evaluating temporal bone trauma.
    • CT imaging improves the understanding of the extent of injury, guiding surgical interventions.
    • The use of CT in temporal bone trauma enhances diagnostic accuracy and optimizes patient management.
