Abstract

Aim. The optimal treatment for chronic subdural hematoma (CSDH) is not yet well defined and research for efficient surgical solutions continues. Burr hole craniotomy (BHC) is a common treatment and twist drill craniostomy (TDC) is a less invasive alternative. A closed-system drainage with subdural expansion catheter and suction reservoir can be used to enhance the TDC procedure. Methods. We report preliminary results of a prospective study comparing BHC and TDC with suction drainage, in a series of 47 patients randomized into two treatment groups. One group of 22 patients underwent TDC with closed-system drainage and suction reservoir (14 men, 8 women, mean age 78.7 years). Another group of 24 patients underwent BHC with subdural irrigation and closed drainage (16 men, 8 women, mean age 76.3 years). Neurological status was assessed by Markwalder's Grading Scale on admission and at follow-up. All patients underwent computed tomography (CT) before surgery, within 4 days after it, and 1 and 2 months later. Results. Preoperative clinical and radiological data were similar in the two groups. Operating times were shorter in the TDC group, while drainage time was shorter in the BHC group (P
