Abstract Introduction Optic canal connects orbit to middle cranial fossa. Optic nerve and ophthalmic artery pass through this canal. The aim of the present study is to make morphometric and anatomical observations of endocranial opening of optic canal. Materials and Methods The observations were conducted on 30 dry adult human skulls. The observations were made on shape, margins, confluence, septations, dimensions, and distance of optic foramen from apex of petrous temporal bone. Result and Statistical Analysis On morphometric observation, transverse diameter (TD) was 6.00 mm and 6.15 mm on the left and the right side, respectively. The vertical diameter (VD) was 5.14 mm on the left side and 4.82 mm on the right side. The distance of optic foramen to apex of petrous temporal bone was 21.84 mm on the left side and 21.90 mm on the right side. The mean, standard deviation, range, and p value were measured by using SPSS software version 19.00. Conclusion In the present study we attempt to provide a comprehensive anatomical and morphometric data of optic foramen that may help ophthalmologists and neurosurgeons during surgery.

The objectives of the present study were to determine the type and morphometric measurements of Foramen magnum (FM) in dry human skulls of Dakshina Kannada district of Southern India. Material and Methods: The present study included 50 adult human skulls of which 32 were males and 18 females. The type of foramen magnum observed macroscopically. Antero-posterior (APD) and transverse diameters (TD) were measured by using stainless steel electronic digital callipers. Foramen magnum Index (FMI) was calculated by using formula FMI = APD/TD. Results: Present study observed 4 types of shapes of foramen magnum, among them ovoid type was found higher frequency (48%). Antero-posterior diameter is a distance between Basion and Opisthion 34.95 mm in males and 34.58 mm in females out of 34.81 mm. The transverse diameters 28.66 mm in males and 28.84 mm in females out of 28.73 mm. Foramen magnum index ≥ 1.2 was considered as ovoid and found in 56% of skulls. Conclusion: We believe that the present study provided additional information about the morphology and morphometric analysis of foramen magnum which is important to radiological, and neurosurgical literature.
