Comparison of One Burr Hole and Two Burr Hole Techniques in the Surgical Treatment of Chronic Subdural Hematomas

Surgical Treatment of Chronic Subdural Hematomas

Abstract

Objective: To compare one or two burr hole techniques in our operated patients with Chronic Subdural Hematoma (CSDH).

Materials and methods: Between January 2013 and December 2021, 104 operations were performed on 84 patients, 62 of which were in one burr hole and 42 were in two burr holes. Data were obtained retrospectively from patient records. Statistical analysis was done with SPSS 25.0 program.

Results: Of the 84 patients, 20 (23.8%) were female and 64 (76.2%) was male. Of 104 operations, 27 (26%) were performed on female patients and 77 (74%) on male patients. The mean age is 72.63 (20-96). Among 104 operations, 52 (50%) hypertension (HT), 39 (37.5%) diabetus mellitus (DM), 16 (15.4%) cardiac failure (CF), 7 (6.7%) choronic renal failure (CRF), 2 (1.9%) coagulopathy, 33 (31%) ,7) had dementia, 38 (36.5%) antiplatelet or anticoagulant use, 20 (19.2%) smoking, 11 (10.6%) alcohol addiction, 65 (62.5%) head trauma. Operation time and postoperative hospital stay were 31.6 minutes in a burr hole, respectively. and 7.3 days, 60 minutes in two burr holes. and it was 7 days. Recurrence developed in 3 patients, 2 of whom had CRF. Two of them were two burr holes and one was a hole operation. There was no significant difference in the comparison of one burr hole and two burr hole data, except for the operation time. The effectiveness of risk factors on the development of recurrence was significant only for CRF.

Conclusion: One burr hole operation is as effective and safe as two burr holes in the surgical treatment of chronic subdural hematoma. We recommend a burr hole as the operation time is shorter
