OBJECTIVE: To assess the effects of isolated hyoid suspension on subjective and objective @entity27 and to evaluate changes in upper airway anatomy with the help of standardized magnetic resonance imaging. STUDY DESIGN AND SETTING: Fifteen @entity1 received isolated hyoid suspension. Changes in respiratory disturbance index were assessed with polysomnography, and anatomical changes with standardized magnetic resonance imaging. Snoring, @entity25 , and functional parameters were assessed with questionnaires. Lateral x-ray cephalometry was performed preoperatively. RESULTS: Mean respiratory disturbance index was reduced from 35.2 +/- 19.1 to 27.4 +/- 26.2. Forty percent of the @entity1 were classified as responders. @entity25 improved significantly. Relevant changes in upper airway anatomy could not be detected. There were no remarkable differences between responders and nonresponders in regard to imaging. CONCLUSIONS: Hyoid suspension is effective only in a subgroup of @entity1 and does not lead to relevant changes in airway diameters in the awake @entity1 . Magnetic resonance imaging and x-ray cephalometry do not add additional information for @entity1 selection. SIGNIFICANCE: The reported clinical effects of hyoid suspension are more likely due to functional changes in airway collapsibility than to an enlargement of the upper airway.
