Most neurosurgeons currently drained CSDH through single or double burr holes; however, few studies have compared the 2 approaches to drainage. The aim of this study is to compare the recurrent rate following double and single burr hole for CSDH in our practice. This is a randomized controlled study from January 2015 to December 2019 in a neurosurgical unit in Kaduna, Nigeria. All patients with imaging diagnosis of subacute or chronic subdural hematoma who enrolled in the study had either a single or double burr hole. Patients were followed up for 6 months after surgery to assess for recurrence. Data were analyzed using SPSS version 25 for Windows. The Fisher exact test was performed to compare the 2 treatment groups. A 2-sided P value < 0.05 was considered statistically significant. A total of 192 patients were enrolled in the study with 99 in the single-burr hole group and 93 in the double burr-hole group. The overall recurrence rate in this study was 2.6%. The recurrence rate in the single arm was 3%, and in the double arm it was 2.2%. There was no statistically significant difference in recurrence between the 2 groups (P= 1.000). A single burr hole is as efficacious as a double burr hole in terms of relief of symptoms and recurrence, and it has a shorter duration of surgery. A single burr hole is as efficacious as a double burr hole in terms of relief of symptoms and recurrence, and it has a shorter duration of surgery. Due to the aging population, the number of elderly patients in need of cranial surgery for various neurosurgical pathologies is growing. We sought to compare mortality and outcome of elderly patients undergoing cranial surgery with a younger population. This was a retrospective analysis of adult patients undergoing craniotomy or craniectomy for various indications. Patients were allocated to 4 a
