Oropharynx and Tongue Base Although a trend toward improvement was observed at the oropharyngeal and tongue base sites following intervention with the advanced MAD simulator, these changes did not reach statistical significance in either the supine or head rotation positions (oropharynx supine, overall P = 0.072; head rotation, P = 0.392; tongue base supine, NA).
