Obstructive sleep apnea is characterized by recurrent episodes of pharyngeal collapse, which result from a decrease in pharyngeal dilator muscle tone. The genioglossus is a major pharyngeal dilator that maintains airway patency during sleep. Early studies in animal and humans have demonstrated that electrical stimulation of this muscle reduces pharyngeal collapsibility, increases airflow, and m...

introduction: this study aims at examining the difference of pharyngeal airways in patients with different occlusion postures, hoping to im prove diagnostic methods and provide a stable treatment plan for orthodontic patients. materials and methods: the data were ga-thered through cbct radiographies of patients from a specialized center for radiology. in each occlusion group according to the pe...
