- Abstract
Objective: Shape differences of the hyoid bone are important because of its unique location and closely related structures. The aim of the present study was to evaluate morphological aspects of the hyoid bone using computed tomography angiography (CTA). Methods: This study was conducted using head and neck CTA of 406 patients aged between 2--95 years (the mean age was 45). Ethics committee approval was received by the Hacettepe University Medical Faculty Ethics Committee (GO 22/386). The diameter of the hyoid body and fusion of the greater/lesser horn with the body were evaluated together with the shape of the hyoid bone. The variations in the shape of the hyoid bone were classified into four types alternatively to the literature. Results: According to the direction of the greater horn, the classification was defined macroscopically as type 1 (outward), type 2 (inward), type 3 (parallel), and type 4 (asymmetrical). It was determined whether the body width and existence of fusion were related to the classification after they were analyzed separately. The association between the low diameter of the body and the non-fused form was found to be statistically significant. Also, there was a significant difference between the low diameter of the body and the outward type. Conclusion: Differentiations of the hyoid and clinical conditions related to its morphology are particularly important in forensic medicine, radiology, anthropology, and neck surgery. We believe that understanding the complex developmental structure of the hyoid bone will provide data for surgical interventions and research on the neck region.
