To investigate the relationships among tongue volume, hyoid position, airway volume and maxillofacial form in paediatric patients with Class Ⅰ, Class Ⅱ and Class Ⅲ malocclusion. Data of 112 children with malocclusion in the Department of Stomatology, Wuxi Children's Hospital from December 2015 to December 2018 were collected. The children were divided into three groups according to Angle's classification: Class Ⅰ (n=42), Class Ⅱ (n=38) and Class Ⅲ (n=32). Tongue volume was evaluated by oral B-ultrasound, the hyoid position was obtained by lateral cephalogram, then the airway volume and maxillofacial form were evaluated by cone-beam CT (CBCT). Relationship among tongue volume, hyoid position, airway volume and maxillofacial form were analyzed. The data were processed by SPSS 20.0 software package. The tongue volume of Class III was significantly larger than that of Class I and Class II (P<0.05); H-FH and H-MP of Class II were significantly larger than those of Class I and Class III, and H-VL was significantly
