Background: Chronic subdural hematoma (CSDH) is a well-known entity and common surgical disorder managed by the neurosurgeon and, if not recognized and treated timely, may prove fatal. It can be non-traumatic or post-traumatic and all of them need urgent attention irrespective of aetiology. It manifests with a progressive neurologic deficit that occurs >3 weeks following head injury. The principal techniques used in the treatment of CSDHs presently are burr hole, twist drill craniostomy, craniectomy and craniotomy.
Objective: The aim of this study was to assess clinical outcome in unilateral chronic subdural hematoma patients treated by single or double burr-hole drainage. This prospective study was carried out at the Department of Neurosurgery, IMS, BHU, Varanasi from September 2016 to August 2018. A total of 60 patients with their age ranged from 22to 88 years with GCS 6 to 15 & hematoma thickness 10mmc were included in this study and randomly divided into two groups using random allocation software. In group A, patients with chronic subdural hematoma (CSDH) were managed with single burr-hole drainage. In group B, patients were managed with double burr-hole drainage. Clinical outcome was measured on the1st postoperative day, 3rd postoperative day and 7th postoperative day by GCS and at 1month follow-up by measuring the Glasgow outcome scale (GOS).
Result: In this study double burr-hole drainage and single burr-hole drainage surgery shows equal success in the management of CSDHs with single burr hole taking less operative time.
