| Abstract | ||
| The Hyoid bone is a small (mostly U-shaped) bone located in the front of neck at level of 3rd cervical vertebra attached to several important ligaments and muscles. It's involved in breathing , chewing , swallowing and speech . In our study we aimed at determining age and sex differences regarding morphology and position of hyoid bone using 3D and 2D CT. Our study was carried out retrospectively on head and neck CT scan films of 120 normal living Egyptian individuals which were done in Benha University hospitals .These individuals divided into 3 age groups, each one contained 40 individuals(Group 1 : from 20 to 39 years old , Group2 : from 40 to 59 years old , Group 3 : from 60 years old onwards ). Each group contained 20 males and 20 females of the same age group. Through these CT films, some measurements were taken which were: degree of fusion between hyoid body and greater horn, length and height of hyoid bone body, length of greater horn, angle between body and greater horn, hyoid width, hyoid length, MP.H. (Mandibular plane – hyoid distance) and H.RGn (Hyoid – Retroganthion distance). Different shapes of hyoid bone were recorded and its association with certain sex. The measurements were analyzed statistically in relation to age and sex. We found that there were significant differences between male and female regarding : shape , body length , body height , GH length ,Hyoid width ,Hyoid Length and H.RGn.There were statistically significant differences between age groups regarding fusion , and degree of fusion and body height and MP.H. Finally , we concluded that hyoid bone could be utilized to assign age, sex and race when used in conjunction with other bones of the body . These measurements could also be used to explain etiology of incidence of certain respiratory diseases. | ||
