The Reliability and Influence of Body Position on Acoustic Pharyngometry and Rhinometry Outcomes.

Objectives: The aim of this cross sectional study was to analyze the method error and reliability in acoustic pharyngometry and rhinometry and to analyze the difference between standing and sitting position in acoustic pharyngometry and rhinometry.

Material And Methods: The sample comprised 38 healthy subjects (11 men and 27 women) as part of a control group in another study. The subjects underwent repeated measures of acoustic pharyngometry and rhinometry in standing and sitting position.

Mandibular positioning techniques to improve sleep quality in patients with obstructive sleep apnea: current perspectives.

The purpose of this article is to review 1) mandibular advancement device (MAD) - indication, treatment success, and side effects; 2) maxillomandibular advancement (MMA) surgery of the jaws - indication, treatment success, and side effects; and 3) current perspectives. Both MAD and MMA are administered to increase the upper airway volume and reduce the collapsibility of the upper airway. MAD is noninvasive and is indicated as a first-stage treatment in adult patients with mild-to-moderate obstructive sleep apnea (OSA) and in patients with severe OSA unable to adhere to continuous positive airway pressure (CPAP).
