Randomized clinical trial assessed craniotomy methods for chronic subdural hematoma, using hollow screws and burr holes.

HS trephination showed similar recurrence rates to BH trephination, indicating it can be an effective alternative.
Operation duration was significantly shorter with HS placement at a mean of 3.0 days versus BH's 4.3 days, suggesting less invasive care.
The analysis included 131 patients with a mean age of 77 years, pointing to the demographic changes in healthcare demands.
HS trephination should be considered for modern treatment, supporting evolving requirements within healthcare systems.

Eisenkolb et al. (2025) studied this question.
