Trepanation or craniotomy is a surgical procedure that consists of drilling the skull, until reaching the dura mater, and consequent removal of a piece of bone. Cranial trepanation is mainly done to decompress the brain or to access areas of interest to the neurosurgeon.

Various neurosurgical procedures can be performed through a burr hole, such as endoscopic ventriculostomy, drainage of subdural hematomas, neurosurgical workup, microvascular decompression, stereotaxic surgeries, etc. The cranial trepanation hole is made with a surgical drill, normally with auto-stopping mechanism.
