Abstract

Abstract : Objective: This study focused on evaluating different parts of the airway in patients with hemifacial microsomia classified by the Pruzansky-Kaban classification system. Methods: Volumetric and morphologic airway parameters of 66 children with hemifacial microsomia were measured on 3D models. Using the Pruzansky-Kaban system, the patient cohort was composed of seven I-type, 14 IIa type, 27 IIb type, and 18 III type patients. Results: The total airway volume was not statistically different among groups. In the 3D oropharynx models, volume and surface area of the oropharynx decreased from the type I group to the type IIb group. However, no statistically significant difference was found for length ( P = 0.965) or minimum cross-sectional area (mini-CSA, P = 0.550) of the oropharynx in the type III group compared to the other groups. In the 3D laryngopharynx models, the mean-CSA ( P = 0.413) and mini-CSA ( P = 0.378) were not statistically different among groups. In contrast, volume ( P = 0.014), length ( P = 0.005), and surface area ( P = 0.032) of the laryngopharynx were reduced from type I to type III. Kruskal–Wallis analysis indicated statistically significant differences of volume ( P = 0.004), length ( P = 0.017), and surface area ( P = 0.010) of the laryngopharynx among groups I, IIa, and IIb. The mean-CSA ( P = 0.247) and mini-CSA ( P = 0.206) of the laryngopharynx were not correlated with the different clinical types. Conclusion: The mean-CSA varied significantly from type I to IIb at the level of oropharynx. In addition, the volume of the laryngopharynx decreased from type I to type III. However, type III was unique in this study with nonseverely airway measurement results. Abstract : Supplemental Digital Content is available in the text
