Key summary points
To determine the intracranial pathologies and treatment outcome after mild traumatic brain injury (mTBI) in patients aged ≥65 years referred to a clinic for oral and maxillofacial surgery.
AbstractSection FindingsAcute and delayed intracranial hemorrhage and mortality rates are low in older patients after mTBI. Factors that increase the risk of intracranial complications are a decreasing Glasgow Coma Scale score, loss of consciousness, amnesia, cephalgia, somnolence, dizziness, and nausea. These findings may be useful for indicating a repeat CT scan.
AbstractSection MessageTriage guidelines on screening and management of older patients with mTBI must be revised to improve patient outcomes.
Abstract
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.

Ethical statement
This research was conducted in full accordance with the ethical standards of the institutional research committee as well as with the 1964 Helsinki declaration and its later amendments or comparable ethical standards. For this non-interventional observational retrospective study, patient data were referenced with the understanding and written consent of the patient, and all data were also anonymized and de-identified prior to analysis. In the3 case of non-adults, written consent was given by one of the parents. Full compliance with data protection and safeguarding of data was ensured and no information which could identify the patients was collected. Reporting was based on the recommendations of the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) initiative [56].
