Abstract

Abstract:

Objective

To discuss the methods and contraindications of extradural anterior micro-clinoidectomy during operation of anterior clinoid process meningioma and its experimental basis and anatomical basis of protection for optic nerve.

Methods

Visual acuity recovery of 16 consecutive cases of anterior bedside meningioma with visual impairment before operation, admitted to Neurosurgery Department of Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School from March 2016 to February 2019, were analyzed retrospectively. Before operation, decrease of visual acuity was the commonest complain in all 16 cases. Visual acuity level: light-sense in 3 cases, hand-movement in 2 cases, finger-count in 3 cases and 0.1 in 2 cases, 0.2 in 3 cases, 0.4 in 2 cases, 0.5 in 1 case.

Results

Simpson Grade Ⅱ resection was achieved in 12 cases, Grade Ⅲ resection in 4 cases. The average follow-up was 15 months. There was no death in this group, there was no change in visual acuity level in 4 cases: 3 cases of light-sense, 1 case of hand-movement, and the visual acuity level of the other patients was improved.

Conclusion

For patients with anterior clinoid process meningioma, the early-stage extradural anterior micro-clinoidectomy has a positive effect on the protection and recovery of vision.
