Abstract:
Objective To discuss the clinical diagnostic and guiding treatment value of changed positions of hyoid bonein the upper airway of patients with obstructive sleep apnea hypopnea syndrome. Methods 128-slice computed tomography was performed for 52 patients with severe OSAHS and 32normal healthy people to measure thehyoid bone in the upper airway in sober state and Muller maneuver. The correlationsbetweenthese indexes were analyzed under linear relation. Results (1)In comparison of the Muller maneuver with sober state , chinnodules and palatal plane to the hyoid in the OSAHS group were statistically higher than the healthy controlgroup (P < 0.001). (2)The distance of hyoid to chinnodules in the OSAHS group was significantlylonger and greater than that of the healthy control group (P < 0.001).(3)The distance of palatal plane to the hyoid was positively correlated with AHI , while thedistances of palatal plane andchinnodules to the hyoidwere both negatively correlated with MSaO2. Conclusion The changes ofhyoid positionare indicative for the clinical diagnosis and is helpful for the guidance of clinical treatment of OSAHS.
