Morphological Classification and Sexual Dimorphism of Hyoid Bone : New Approach

Hyoid bone is a part of viscerocranium placed between the tongue root and thyroid cartilage to which it is connected by thyrohyoid membrane. Widely accepted morphological classification does not exist. Sexula dimorphism was analysed in this study and new guidelines for anatomical classificationof hyoid bones based on anthropometric parameters were given. Total number of analysed bones was 70. The bones were classified into three groups: symmetrical U-type, symmetrical V-type and asymmetrical type according to the angle between greater horns and the proportion of greater horns lenght. In the females incidence of asymmetrical type considerably higher than in the males, while the incidence of symmetrical V-type is lower. The angle value that is on average higher in males may be the parameter indicating that in puberty hyoid bone, still not completely ossified, to some extent follows development of thyroid cartilage because of their close anatomical relation.
