This study was carried out to test the hypothesis that changes in head/body position induce
changes in upper-airway dimensions. Contiguous images were obtained by means of …

State-dependent changes in upper airway caliber were studied with magnetic resonance
imaging (MRI) techniques. We hypothesized that changes in airway caliber during sleep in …

Abstract Study Objectives: To examine changes in the upper-airway dimension and its
surrounding structures induced by mandibular advancement during sleep. Design: Eleven …

Impaired nasal breathing has been reported to cause changes in human head posture. The
aim of this study was to assess whether there was any relationship between nasorespiratory …

The purpose of this study was to examine sleep-related changes in the upper airway and
surrounding structures including the mandible, hyoid bone, and cervical vertebra in normal …

summary Vertical mandibular position is considered to have an effect on the patency of the
upper airway, because mouth opening is associated with a backward and downward …

The occurrence of upper airway obstruction during sleep and with anesthesia suggests the
possibility that upper airway size might be compromised by the gravitational effects of the …

Comparison of posterior airway space was evaluated radiographically on patients with sleep
apnea in a mandibular reposed position vs. a mandibular protruded position. This was …

The aim of this study was to develop a method of studying the effects of mandibular
advancement on oropharyngeal airway dimensions in the sagittal plane in conscious …

Oral appliances for the treatment of obstructive sleep apnea (OSA) produce either
mandibular or tongue protrusion, and are thought to enlarge the upper airway (UA). We …
