Duplication of Optic Canal in Human Skulls

Duplication of optic canal is a rare anomaly. 194 Human skulls were collected from the Department of Anatomy, Subharti Medical College Meerut, LLRM Medical College Meerut and Seema Dental College Rishikesh. These skulls were of the age between 18-70 years and included both male and female skulls. Out of these, 5 skulls showed duplication of optic canal. 3 skulls showed bilateral duplication and 2 skulls showed unilateral duplication . It is important to know this anatomical variation during interventional procedures of optic canal and surrounding regions especially during endoscopic tumor removal and optic nerve decompression.
