objective: adaptation of the pharyngeal airway space does occur after different surgical strategies of class iii patients including mandibular setback, maxillary advancement and bimaxillary surgery. the aim of this study is to conduct a detailed cephalometric evaluation of the alterations taking place in the morphology of the pharyngeal airway space after treatment of class iii skeletal deformi...

Introduction: Acute epiglottitis or supraglottitis is a rapidly progressing upper respiratory tract infection that can often threaten the airway patency. Epiglottic abscess that expands to the paraglottic (PGS) or preepiglottic (PES) space and acute airway obstruction constitute rare complications, exclusively presented in adults.   Case Report: We report two cases. In t...

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 within one wee...

conclusions our study revealed weak correlation between pe/e-vc and cormack-lehane grade, with 87% sensitivity and 30% specificity. therefore, we concluded that sonographic measurement criteria are not accurate in airway evaluations before anesthesia. results it was observed that correlations between the pre-epiglottic space (pe) and cormack-lehane grades i, ii, and iii were weak. correlations ...

results sixty patients were involved in this study. in asv mode, values including peak airway pressure (p-peak), end-tidal carbon dioxide (etco2), tidal volume and respiratory dead space were significantly lower than simv mode. although the mean value for dynamic compliance had no significant difference in the two types of ventilation, it was better in asv mode. methods in a crossover study, pa...

asthma is a chronic inflammatory disease of the airway with extensive airway remodeling. the ethical issues associated with the studies in asthmatic patients, required development of animal model of asthma. animal models of asthma can provide valuable information on several features of asthma pathogenesis and treatment. although these models cannot carry out all clinical features, they are valu...

background: increasedlife expectancy in populations has brought along specific new scenarios in the fields of medicine for the elderly; prevalence of physical complications such as edentulism and patients with dentures is growing. management of anesthesia and ventilation in this group of patients has turned into a great challenge. some researchers suggest dentures to be left in place during bag...
