Anterior circulation aneurysms have classically been treated using the pterional (PT) craniotomy. Minimally invasive alternatives to the PT craniotomy have been successfully used to treat vascular pathologies of the anterior circulation. These approaches offer smaller incisions and reduced tissue dissection, resulting in shorter hospital stay, improved cosmetic results, and comparable outcomes for aneurysm treatment compared with classic open approaches. The supraorbital, lateral supraorbital (LSO), mini-PT, minimal interhemispheric, and endoscopic transpterional port approach (ETPA) are each best suited for different aneurysm targets. Outpatient aneurysm surgery has been possible with the use of minimally invasive approaches.
