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.
