(a) Comparison of the anteroposterior diameters of the six sites between baseline and data with the mandibular advancement appliance (MAA). Abbreviations: EPS, epiglottic pharyngeal space; IPS, inferior pharyngeal space; MA, minimum area; MPS, middle pharyngeal space; PPS, palatal pharyngeal space; SPPS, superior posterior pharyngeal space. (b) Comparison of the widths of the six sites between baseline and data with the mandibular advancement appliance (MAA). Abbreviations: EPS, epiglottic pharyngeal space; IPS, inferior pharyngeal space; MA, minimum area; MPS, middle pharyngeal space; PPS, palatal pharyngeal space; SPPS, superior posterior pharyngeal space. (c) Comparison of the cross-sectional area of the six sites between baseline and data with the mandibular advancement appliance (MAA). Abbreviations: EPS, epiglottic pharyngeal space; IPS, inferior pharyngeal space; MA, minimum area; MPS, middle pharyngeal space; PPS, palatal pharyngeal space; SPPS, superior posterior pharyngeal space.
