Abstract

Previous studies have primarily focused on the relationship between airway morphology and craniofacial structure, with greater emphasis on sagittal rather than vertical dimensions. However, the association between skeletal malocclusion patterns and respiratory function remains unclear. Although three-dimensional studies have reported increased airway size following orthodontic treatment, morphological changes do not necessarily reflect functional improvement. Airway function depends on airflow resistance and respiratory muscle activity, with respiratory muscle strength (RMS) being an important parameter. This study aimed to evaluate RMS in patients with different skeletal malocclusion patterns and to investigate its relationship with airway dimensions measured by CBCT. The results showed that RMS was highest in Class II (5.8 ± 5.5), followed by Class I (4.6 ± 4.3), and lowest in Class III (3.9 ± 3.0), with a significant difference between Class II and Class III (p = 0.006; ANOVA p = 0.005). These findings indicate differences in respiratory function among skeletal patterns, suggesting that combining RMS assessment with airway morphological analysis may improve orthodontic diagnosis and treatment planning
