Objective(S):
To compare the incidence of acute and chronic complications of temporal bone fractures, and identify predictors for post-injury, audiometrically confirmed hearing loss.
Methods:
Retrospective cohort analysis of patients with acute temporal bone fractures who underwent both in-hospital and outpatient follow-up Otolaryngology evaluation at an academic, tertiary-care institution from January 2002 to January 2023. Otologic outcomes were compared between initial and follow-up evaluations. Logistic regression analysis was used to identify predictors of audiometric hearing loss.
Results:
577 subjects with acute injuries were reviewed; 220 met inclusion criteria. Compared with initial evaluation, the incidence of hemotympanum (57% vs. 5%, p < 0.001), external auditory canal injury (18% vs. 8%, p = 0.01), facial nerve weakness (7% vs. 4%, p = 0.016), and cerebrospinal fluid otorrhea (6% vs. 0%, p < 0.001) significantly decreased at follow-up. There were no differences in rates of subjective hearing loss, tympanic membrane injury, or ossicular disruption. Formal audiograms were performed in 82 subjects. 47 (57%) demonstrated hearing loss, almost half of which were pure sensorineural. Multivariate regression identified age (Odds Ratio [OR]: 1.03, p = 0.036), intracranial bleeding (OR: 7.49, p = 0.004), and lateral dural venous sinus thrombosis (OR: 10.5, p = 0.039) as predictors for audiometric loss.
Conclusions:
Temporal bone fractures are complex injuries often associated with numerous intra-temporal and extra-temporal complications. Various otological sequelae persist upon hospital discharge. Yielding insight about the natural history of such injuries, these results aid in patient counseling, identifying subjects at risk for long-term problems, and necessitating follow-up.

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
01:22Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
