BACKGROUND Scarring airway stenosis is commonly seen in China as compared to other developed countries, due to the high prevalence of tuberculosis. Nowadays, interventional bronchoscopy treatment has been widely used to treat this disease in China. This study demonstrated the characteristics of scarring airway stenosis in Chinese adults and retrospectively evaluated the efficacy of intervention...

Introdouction: The aim of this study was to compare information regarding pharyngeal airway sizes in adolescent subjects with different malocclusion classes obtained from lateral cephalograms and 3–dimensional (3D) cone-beam computed tomography (CBCT) scans. Materials and methods: In this prospective cross-sectional study, CBCT scans and lateral cephalograms of 35 subjects, taken with...

every day; however, none is more important than effective airway management. The loss of an airway is one of the most common causes of morbidity and mortality in severely ill or injured children. It may occur suddenly, without any warning, and requires immediate action; therefore, all emergency medicine physicians must possess knowledge of the management of an airway using rapid sequence intuba...

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...

the impulse oscillation system (ios) measures respiratory impedance (zrs) in terms of resistance (rrs) and reactance (xrs) at multiples of 5 hz. these measurements can be used clinically to help diagnose and monitor respiratory disorders, independent of effort. there is, as yet, no information on reference values for ios in iranian adolescents. the predictive equation for resistance and impedan...
