Investigation of Morphology of the Hyoid Bone According to Age and Gender With Multidetector Computarized Tomography

Introduction: In our study, we aimed 200 cases were evaluated for the length, width and angle of hyoid bone and its distance from certain anatomical structures. Methods: This study was perfomed retrospectively in 2010 - 2013 on 200 CT images. 3D volume rendering images of pure hyoid bone were created from the axial CT images in 1 mm slice thickness. In our study, 200 cases (94 female, 106 male) were evaluated for the length, width and angle of hyoid bone and its distance from certain anatomical structures. Results: In our study, differences in the length and width measurements of the body were observed just until the 20-29 age group, the measurements were found to be statistically major in men than women. Relationship between cervical vertebrae and hyoid varies; it was found to be located between C3-C4 up to 29 years old. As age grows it descends to the C4 level and after that, it remains constant at this level. Conclusion: By associating this bone with a bunch of surrounding structures, measurements were performed and by comparing these measurements with results of similar.
