Abstract :Objective: This study aims to analyze the morphological and morphometric features of the hypoglossal canal insert ignore into journalissuearticles values(HC); and its topographical relationship with the occipital condyle insert ignore into journalissuearticles values(OC); and to present guiding information to the relevant field experts. Material And Method: This research was carried out with 33 adult Turkish skulls of unknown gender. Typing definitions of the skulls without damage to the posterior cranial fossa were made with the parameters related to a standard caliper and a protractor. Results: The distance of the extracranial opening of the HC to the posterior end of the OC was 14.37±1.76 mm on the right side and 16.37±1.76 mm on the left insert ignore into journalissuearticles values(p<0.05);, while the intracranial opening was determined to be greater than that of the OC and its distance to the posterior end was calculated as 8.95±1.00 mm on the right side and 10.41±1.24 mm on the left side insert ignore into journalissuearticles values(p<0.05);. The angle between the extracranial opening of the HC/pharyngeal tubercle was 45.97±2.06 degrees on the right side and 48.05±2.97 degrees on the left side insert ignore into journalissuearticles values(p<0.05);. It was determined that Type I was observed most frequently on the right side with a rate of 42.42% and on the left side with a rate of 18.18%. Bilaterally, only Type I and Type II b were detected. Discussion: We believe that our research will guide surgeons, anatomists, and anthropologists in terms of making transcondylar, supracondylar, and lateral suboccipital approaches and examining the canal differences in Turkish society.
