Research Abstract

The aim of this present study was to investigate the influence on the upper airway of the size ratio of tongue and mandible (T/M ratio) with CT data. We investigated simple correlations between our anatomical variables (airway, tongue, and mandible volume, and T/M ratio), BMI, and AHI. There was a significant positive correlation between BMI and tongue volume, and BMI and T/M ratio. There was a negative correlation between airway volume and T/M ratio. We estimate that the alteration of T/M ratio due to increased BMI is likely to be involved in the development of OSA.
