Neuroendoscopy-assisted Drainage Versus Burr Hole Drainage for Chronic Subdural Hematoma

Chronic subdural hematoma (CSDH) is a frequent condition in neurosurgery, leading to fluid accumulation between the meninges, brain compression, neurological dysfunction, and potentially herniation. The efficacy of treatments and their long-term outcomes remain uncertain, with no established standard. Notably, neuroendoscopy-assisted hematoma evacuation, in contrast to burr-hole drainage, enables direct visualization and thorough removal of the hematoma, thereby minimizing residue, lowering recurrence rates, and shortening drainage duration. This study will undertake a multicenter trial to compare these two methods and determine the superior treatment approach for CSDH.
