Abstract :Background: To examine the changes in pharyngeal airway dimension and hyoid bone position with the effect of rapid maxillary enlargement during the treatment of skeletal Class II malocclusion with functional appliances. Methods: Patients with skeletal Class II malocclusion were divided into two groups; Group 1 consisted of 25 patients insert ignore into journalissuearticles values(8 males, 17 females); with a mean age of 11.41±1.13 who treated with twin-block appliance with rapid maxillary expansion appliance and Group 2 who only received twin-block therapy consisted of 25 patients insert ignore into journalissuearticles values(12 males, 13 females); with a mean age of 11.92±0.65. In this study, 11 angular and 3 linear measurements were used for skeletal evaluation of maxillary and mandibular on cephalometric X-rays of initial and intermediate records of 50 patients and 13 linear measurements were performed for pharyngeal airway evaluation. Results: According to the intra-group t test results, in skeletal evaluation of the maxillary and mandibular, 8 angular and 2 linear measurements for group 1, 9 angular and 2 linear measurements for group 2, in pharyngeal evaluation all measurements of group 1 and 11 linear measurements for group 2 were significant differences insert ignore into journalissuearticles values(P < .05);. According to the intergroup t test results, there were significant differences in skeletal assessment and pharyngeal airway evaluation insert ignore into journalissuearticles values(P < .05);. Conclusion: While the contribution of RME to the increase of pharyngeal airway dimensions was shown, the effect of the functional appliances on this region is greater.
