Does transpalatal distraction affect pharyngeal airway dimensions and related soft tissues?
The results of this study suggest that, in adult patients with nasal obstruction, TPD has the potential to increase sagittal nasopharyngeal airway dimensions and the minimal oropharyngeal distance behind the tongue, with an elevation in tongue posture. Further studies using cone-beam computed tomography that focus on how the bone-borne expander alters pharyngeal airway volume will make valuable contributions to the literature.
In a brain slice model of cerebral anoxia, 1 minimum alveolar concentration isoflurane decreases glutamate release to a similar extent that hypothermia (28 degrees C) does. The increased glutamate release with hyperthermia (39 degrees C) is not prevented by isoflurane.
