====== Supratentorial craniotomy ======

For supratentorial [[craniotomy]], surgical access, and closure technique, including placement of subgaleal drains, may vary considerably.

The incidence of [[seizure]]s following supratentorial [[craniotomy]] for non-traumatic pathology has been estimated to be between 15% to 20%; however, the risk of experiencing a seizure may vary from 3% to 92% over a five-year period. Postoperative seizures can precipitate the development of [[epilepsy]]; seizures are most likely to occur within the first month of cranial surgery. The use of [[antiepileptic drug]]s (AEDs) administered pre- or postoperatively to prevent seizures following cranial surgery has been investigated in a number of [[randomised]] [[controlled trial]]s (RCTs).

There is little evidence to suggest that AED treatment administered prophylactically is effective or not effective in preventing post-craniotomy seizures

)).

The current evidence base is limited due to the differing methodologies employed in the trials and inconsistencies in reporting of outcomes. Further evidence from good-quality, contemporary trials is required in order to assess the effectiveness of prophylactic AED treatment compared to control groups or other AEDs in preventing post-craniotomy seizures properly
