Abstract:
OBJECTIVE: Chronic subdural hematoma drainage is one of the most common procedures performed in neurosurgical practice. Not only burr hole drainage but also small craniotomy (diameter 3–5 cm) is frequently used neurosurgical treatment of chronic subdural hematomas. We assessed to compare the postoperative recurrence rates between burr hole drainage versus small craniotomy with closed-system drainage for chronic subdural hematomas. METHODS: From January 2016 to December 2018, 75 patients who were treated with burr hole drainage and small craniotomy with closed system drainage for the symptomatic chronic subdural hematoma were enrolled. Pre and postoperative computed tomography (CT) were used for radiologic evaluation. The choice of procedure was decided by preoperative CT images. RESULTS: 60 patients out of 75 patients underwent burr hole drainage, whereas 15 patients underwent small craniotomy. The overall postoperative recurrence rate was 16%. The recurrence occurred in 8 patients out of 60 patients in burr hole drainage group (13.3%) and 7 patients out of 15 patients in small craniotomy group (46.7%). The number of days of hospitalization was 10.3 days in burr hole drainage group and 15.7 days in small craniotomy group. CONCLUSION: Burr hole drainage would be sufficient to evacuate chronic subdural hematoma with lower recurrence rate, but small craniotomy was also needed in some cases such as hematoma has solid portion or multiple septum.
