Abstract

Objective: To evaluate the surgical results of anterior cranial basal meningiomas by the keyhole eyebrow approach. Methods: A retrospective study of a series of clinical cases of meningiomas undergoing keyhole eyebrow surgery from October 2020 to June 2022 at the Center for Neurosurgery - Viet Duc Friendship Hospital. Results: There were 40 clinical cases operated, in which female predominates with 82.5% (33 patients). The main clinical manifestations were headache 77.5%, blurred vision 47.5%, hemianopia 25% and 2 patients anosmia. The mean size of the tumors was 24.5 mm, the mean operative time was 3 hours. The possibility of total tumor resection was 85% (34 patients), 4 patients (10%) had most of the tumor removed (>90%) and there were 2 cases of partial resection. Common complications during surgery were brain contusion in 10% (4 patients) and hematoma in 10% (4 patients). There were 2 cases of postoperative wound infection. There were no deaths after surgery, the ability to improve vision was 84% (16/19 patients had visual damage before surgery). Conclusion: Our experience shows that the keyhole eyebrow approach allows successful resection of meningiomas, less complications, shorter surgery time and good esthetic effect.
