Management of older adults after mild head trauma in an oral and maxillofacial surgery clinic.

PURPOSE: The primary aim was to determine the incidence of intracranial hemorrhage (ICH) after mild traumatic brain injury (mTBI) in patients aged ≥ 65 years. The secondary aim was to identify risk factors for intracranial lesions and evaluate the need for in-hospital observation in this age group.

METHODS

This observational retrospective single-center study included all patients aged ≥ 65 years who were referred to our clinic for oral and plastic maxillofacial surgery following mTBI over a five-year period. Demographic and anamnesis data, clinical and radiological findings, and treatment were analyzed. Acute and delayed ICH and patient outcomes during hospitalization were evaluated using descriptive statistical analysis. A multivariable analysis was performed to find associations between CT findings and clinical data.

RESULTS

A total of 1,062 patients (55.7% male, 44.2% female) with a mean age of 86.3 years were included in the analysis. Ground-level fall was the most frequent cause of trauma (52.3%). Fifty-nine patients (5.5%) developed an acute traumatic ICH, and 73 intracerebral lesions were radiologically observed. No association was detected between ICH rate and antithrombotic medication (p = 0.4353). The delayed ICH rate was 0.09% and the mortality rate was 0.09%. Significant risk factors for increased ICH were a Glasgow Coma Scale score of < 15, loss of consciousness, amnesia, cephalgia, somnolence, dizziness, and nausea according to multivariable analysis.

CONCLUSION

Our study showed a low prevalence of acute and delayed ICH in older adults with mTBI. The ICH risk factors identified here should be considered when revising guidelines and developing a valid screening tool. Repeat CT imaging is recommended in patients with secondary neurological deterioration. In-hospital observation should be based on an assessment of frailty and comorbidities and not on CT findings alone.
