Retrospective study on change in pharyngeal airway space and hyoid bone position after mandibular setback surgery
OBJECTIVES The purpose of this study was to evaluate changes in the pharyngeal airway space and hyoid bone position after mandibular setback surgery with bilateral sagittal split ramus osteotomy (BSSRO) and to analyze the correlation between the amount of mandibular setback and the amount of change in pharyngeal airway space or hyoid bone position. MATERIALS AND METHODS From January 2010 to F...
متن کاملDevelopmental changes in pharyngeal airway depth and hyoid bone position from childhood to young adulthood.
OBJECTIVE (1) To test the hypothesis that there are no developmental changes in the pharyngeal airway depth and hyoid bone position from childhood to adulthood in normal Taiwanese persons, (2) to identify any sexual dimorphism, and (3) to find the predictive value of selective variables for the hyoid bone position. MATERIALS AND METHODS Lateral cephalometric radiographs of 239 normal Taiwanes...
متن کاملThe hyoid bone position in mouth breathers and tongue-thrusters.
In 1981 Bibby and Preston commented on the uniqueness of the anatomic relationships of the hyoid bone, notably that it was not fixed in space by bony articulations. This fact alone makes it a potential indicator of certain individual features of importance in orthodontic diagnosis and treatment. This study investigates the effect of mouth breathing and tongue-thrusting on the hyoid bone positio...
متن کاملRetrospective study of changes in pharyngeal airway space and position of hyoid bone after mandibular setback surgery by cephalometric analysis
BACKGROUND The posterior movement of mandible was known as the main cause of the changes in the pharyngeal airway space (PAS) and the postoperative obstructive sleep apnea (OSA). The purpose of this study was to know the changes of PAS and position of hyoid bone. METHODS Lateral cephalographies of 13 patients who had undergone sagittal split ramus osteotomy (SSRO) setback surgery were taken p...
متن کاملتغییرات موقعیت استخوان هایوئید متعاقب درمان مال اکلوژن class II div1 با دستگاه فانکشنال فرمند1
Background and Aim: Unlike other bones of the head and neck, hyoid bone has no bony articulations. It is connected to mandible, cranium and pharynx through muscles and ligaments. During treatment with functional appliance in patients with class II div1 malocclusion, mandible is positioned in inferior and anterior direction. Regarding the relation between hyoid and mandibular bone, alterations o...
