The goal of this clinical trial is to compare the outcome of double burr hole versus single burr hole in patients of chronic subdural hematoma undergoing subdural drain evacuation. The main questions it aims to answers are 1\. Which one of the surgical method i.e single burr hole or double burr hole is clinically superior with better post operative prognosis for the drainage of chronic subdural hematoma. 2 Compare the post operative complications in both the techniques in term of wound infection hospital stay duration , recurrence and mortality. participants will be divided in two groups one group will be treated with single burr hole technique second group will be treated with double burr hole technique. After procedure, patients will be followed-up in hospital until discharge and total hospital stay will be noted. Patients will be followed-up further in OPD . During follow-up, patients will be evaluated for wound infection, recurrence and mortality.

Recurrence Of Chronic Subdural Hematoma
Timeframe: From date of surgery until radiologically confirmed recurrence (defined as subdural hematoma volume >15 mL or significant mass effect on CT brain) requiring repeat intervention, assessed up to 3 months postoperatively
quantity of hematoma evacuated
Timeframe: Measured intraoperatively at the time of surgery and cumulatively measured postoperatively from surgery until removal of the subdural drain, assessed up to 72 hours postoperatively.
