Burr-hole drainage is a standard surgical treatment, but the hematoma may come back in some patients and require another procedure.This study will test whether using a patient-specific 3D-printed template to guide burr-hole placement, combined with coagulation of the middle meningeal artery during surgery, can reduce the risk of hematoma recurrence compared with standard burr-hole drainage.Participants with symptomatic chronic subdural hematoma who need surgery will be randomly assigned to one of two groups. One group will receive standard burr-hole drainage. The other group will receive 3D-printed template-guided burr-hole drainage with attempted intraoperative frontal branch of the middle meningeal artery coagulation when it can be safely performed.The main outcome is whether the hematoma comes back and requires another invasive treatment within 3 months after surgery. The study will also assess brain imaging results, neurological recovery, complications, hospital stay, and the feasibility and safety of the 3D-printed template and artery coagulation procedure.",[78],"Chronic Subdural Hematoma",[80,81,82,83,84],"Chronic subdural hematoma","Middle meningeal artery","Middle meningeal artery coagulation","3D printing","Burr-hole drainage","NOT_YET_RECRUITING","2026-07-22",{"date":88,"type":89},"2026-07-23","ACTUAL",{"date":91,"type":72},"2027-01",{"date":93,"type":72},"2029-06",{"name":5,"class":6},1]
