Inner membrane opening during the burr-hole evacuation of a chronic subdural hematoma: risk-adding or recurrence-preventing?

Abstract

Chronic subdural hematoma (CSDH) is a common situation in neurosurgical practice. Only a few studies had mentioned the opening of the inner membrane during the burr-hole evacuation of a CSDH. This study was designed to assess the benefits of inner membrane opening in the burr-hole evacuation of a CSDH and to find out if there is an added risk of such step that overweighs its benefits.
