Chronic Subdural Hematoma Following Maxillofacial Fracture : Report of 2 Cases

Chronic subdural hematoma generally occurs following craniocerebral trauma but is not a common complication following oral and maxillofacial trauma. In this report, we describe two cases of chronic subdural hematoma that appeared one month following maxillofacial trauma in elderly patients. Although the direct craniocerebral trauma was initially denied by emergency physicians through primary survey, oral and maxillofacial surgeons have found CSDH during post-trauma follow-up courses in both cases. Then neurosurgical intervention by neurosurgeons was required for them. These reports suggest that the risk of chronic subdural hematoma should be kept in mind in elderly patients who have sustained maxillofacial trauma and in those taking antiplatelet drugs. Follow-up computed tomography is important, even in patients without any abnormal neurologic signs or symptoms.
