Objective:
Ballistic injuries to the temporal bone are uncommon but devastating injuries that damage critical neurovascular structures. This review describes outcomes after ballistic injuries to the temporal bone and offers initiatives for standardized high-quality future research.
Data Sources:
A systematic search of PubMed, Embase, and Cochrane.
Review Methods:
Studies in the review included adults who experienced temporal bone fractures due to gunshot wounds and survived longer than 48 hours. Individual case reports were excluded. The various searches returned 139 results, of which 6 met inclusion criteria.
Results:
Most of the included studies are case series with low-level evidence that report a wide range of outcomes and follow-up. Outcomes include demographic patient information, audiologic outcomes, vascular injuries, intracranial complications, facial nerve function, and surgical indications.
Conclusion:
This review is the first to characterize the nature and progression of patients who experienced gunshot wounds to the temporal bone. Although all patients share an etiology of injury, they often have vastly different hospital courses and outcomes. This review provides a basis for future studies to guide care for these injuries, as most of the existing literature includes small dated case series.
