Developmental 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 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...

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 کاملTreatment of dental and skeletal bimaxillary protrusion in patient with Angle Class I malocclusion.
In the orthodontic clinic, skeletal and dental bimaxillary protrusion is presented frequently as one of the factors leading patients to seek orthodontic treatment, mainly due to the esthetic involvement it has. The patient of this article illustrates this situation, being deeply uncomfortable with her esthetic appearance, due to the excessive upper incisors exposure and problems with lip sealin...
متن کاملPharyngeal Airway Changes after Bimaxillary Orthognathic Surgery--Preliminary Results.
INTRODUCTION Dentofacial deformity, a deviation from normal facial proportions and dental relationships, is corrected by jaw repositioning in all three spatial planes, which changes the position and tension of the surrounding tissues, bones and muscles. These changes may also affect the dimensions of the pharyngeal airways (PA). OBJECTIVE The aim of this study was to evaluate and compare thre...
