Comparison of Skeletal, Dental, Soft Tissue, Hyoid Bone, Tongue and Pharyngeal Airway Measurements Before and After Treatment of the Double Jaw Surgery Group. Note: Data presented as mean±standard deviation, p<0.05*,p<0.01**, p<0.001*** Wilcoxon Signed Ranks Test; Abbreviations: Ver: Vertical Referance Plane, Hor: Horizontal Reference Plane, Nperp: Nasion perpendicular, Co; Condylion OP-SN: Occlusial Plane- Sella-Nasion, U1i: Upper 1. incisor, U6t: Upper 1. molar, L1i: Lower 1. incisor, ULA: Upper Lip Anterior, LLA: Lower Lip Anterior, H: Hyoidale, PNS: Posterior Nasal Spina, PPS: Palatal pharyngeal region, SPSS : Superior posterior pharyngeal region, MPS: Middle pharyngeal region, IPS: Inferior pharyngeal region, EPS: Epiglottic pharyngeal region, D1: The line drawn from the PNS point to the dorsum of the tongue parallel to the vertical reference plane (Ver). D2:It is the distance of the point where the dorsum of the tongue cuts the mandibular plane to the line perpendicular to the Frankfort horizontal plane and passing through the Porion.
