Correlation of AHI and lowest O2 saturation with hyoid bone parameters.

AHI: apnea/hypopnea index.r: Pearson correlation; *: significant (pLH-d: distance between bilateral lesser horns, GH-d: distance between bilateral greater horns, AP: distance from most anterior end of hyoid arch to GH-d, GH-LH, Rt: distance from the right greater to right lesser horn, GH-LH, Lt: distance from the left greater to left lesser horn, H-angle: distance from greater to lesser horn, and anterior angle between bilateral extensive lines from greater to lesser horn.
