Microabordaje transciliar supraorbitario en la cirugía de aneurismas intracraneales de la circulación anterior.

Objective: To asses surgical results in patients with anterior circulation intracranial aneurysms treated by two different approaches, the supraorbital keyhole and pterional craniotomy. Methods: A non-randomized surgical trial was carried out in which the patients was assigned to KHSO group if the approach selected was supraorbital Keyhole or CPT group if the approach was pterional craniotomy. Results: 125 cases were studied, 77 (61.60 %) in KHSO group and 48 (38.40 %) in CPT group. 153 aneurysmal sacs were treated, 93 in KHSO group and 60 in CPT group, 119 rupture (77.77 %) and 34 without rupture (22.23 %). Conclusions: There were no significant differences between the two groups. The supraorbital Keyhole is an alternative option in surgical treatment of anterior circulation intracranial aneurysms.
