Brain abscess surgery

Surgery
Surgery has evolved dramatically over the last few decades.
 * Once requiring open craniotomy and drainage / excision, most procedures are currently minimally invasive, closed, and performed under local anesthesia with conscious sedation and CT guidance.
 * CT guidance is accurate to within 4 – 5mm.
 * Stereotactic drainage can also be used if necessary, and is accurate to within 1 – 2mm.
 * Open craniotomy with complete excision is usually reserved for patients with multiloculated abscesses or in cases due to more resistant pathogens (e.g. fungi and nocardia).
