Abstract

Aims and Objective: To determine the attachment of optic strut relative to anterior clinoid process. To categorize optic strut into the sulcal, pre-sulcal, post-sulcal. To determine the association between laterality and optic strut attachment pattern.
Materials and Methods: The study was conducted on 100 normal CT scans of Head and Para nasal sinus. Optic strut was classified as pre-sulcal, sulcal, post-sulcal, and asymmetric in relation to the prechiasmatic sulcus. Optic strut location was determined as anterior, middle and posterior with respect to anterior clinoid process.
Results: The optic strut was found to be anterior in 28% specimen, middle in 57% specimen and posterior in 15% specimen. The optic strut was pre-sulcal in 31% specimens, sulcal in 50%, post-sulcal in 16%. The above were observed bilaterally, and 3% were unilateral.
Conclusions: Anatomical variations in the optic strut are significant in planning for anterior clinoidectomy and optic-canal decompression.
