Chronic subdural hematoma (CSDH) is a common neurosurgical disorder, and its incidence increases with age. The aim of this study was to compare the outcomes of elderly and younger patients with CSDH who underwent burr-hole craniotomy.
We retrospectively reviewed the records of 79 patients with unilateral CSDH who underwent burr-hole craniotomy. We compared the data of 28 patients older than 80 years and 51 patients younger than 80 years. Each patient’s symptoms, radiologic data, complications, and hospitalization duration were analyzed. Additionally, we evaluated each patient’s modified Rankin Scale (mRS) score to assess the clinical outcomes.
The mean ages of the older and younger patients were 84.5 and 68.6 years, respectively. Older patients were more likely to develop postoperative complications and remained hospitalized for longer because of complications. Both the preoperative maximal hematoma thickness and the pre- and postoperative difference in thickness were greater in the older group. Preoperatively, the younger group contained a higher percentage of patients with an mRS score of 0-2. Six months postoperatively, both groups had similar percentages of patients with an mRS score of 0-2.
Our findings showed that larger hematoma volumes were removed from older group after surgery during similar periods. However, the significantly higher incidence of general complications in the older group led to significantly longer hospitalization. However, the good treatment outcomes and prognosis suggest that burr-hole craniotomy can be an effective treatment even for elderly patients if clinicians remain aware of the prevention and treatment of postoperative complications.
