Measurement | Definition | Interpretation |
---|---|---|
H-Me | The distance between hyoid bone and Menton point | Hyoid bone position in relation to the mandible |
H-EB | The distance between hyoid boneand Epiglottis point | Hyoid bone position in relation to the epiglottis |
C3-H | The distance between the 3rd cervical vertebrae and hyoid bone | Hyoid bone position in relation to the 3rd cervical vertebrae |
C3-Me | The distance between the 3rd cervical vertebrae and Menton point | This line forms the hyoid bone triangle combined with H-Me line, and C3-H line |
H-C3Me | The perpendicular line from hyoid bone to the line connecting the 3rd cervical vertebrae and Menton point | The vertical height of the hyoid bone triangle. A positive value indicated a downward direction of the hyoid triangle, and a negative value indicated an upward direction of the hyoid triangle |
H-PNS | The distance between hyoid bone and PNS point | Hyoid bone position in relation to the maxilla |
H–H | The perpendicular distance running from hyoid bone to a vertical line extending from the Sella point | Horizontal position of hyoid bone |
H-V | The perpendicular distance running from hyoid bone to a horizontal line extending from the Sella point | Vertical position of hyoid bone |
