A comparative CT evaluation of pharyngeal airway changes in class III patients receiving bimaxillary surgery or mandibular setback surgery.
OBJECTIVE The purpose of this study was to compare the morphologic changes of the upper airway space in Class III patients who underwent mandibular setback or bimaxillary surgery (maxillary advancement and mandibular setback) by computed tomography at 2 levels: soft palate and base of tongue. METHODS The sample consisted of 47 subjects in 2 groups who had been diagnosed as having Class III sk...
متن کاملChanges of the Posterior Airway Space Following Orthognathic Surgery in Class III
Objective: Adaptation of the pharyngeal airway space does occur after different surgical strategies of class III patients including mandibular setback, maxillary advancement and bimaxillary surgery. The aim of this study is to conduct a detailed cephalometric evaluation of the alterations taking place in the morphology of the pharyngeal airway space after treatment of class III skeletal deformi...
متن کاملPrevalence of Radiographic Changes of Temporomandibular Joint Condyle in Patients with Skeletal Class II and III
Background and purpose: Temporomandibular joint (TMJ) disorders are abnormalities that interfere with the shape or normal functioning of the joint, characterized by a group of clinical symptoms including pain, joint sounds, and limitation or deviation when opening the mouth. Considering the effect of skeletal relationships of the jaw on the shape, size, and morphologic variations of the condyle...
متن کاملupper airway dimensions in patients with class ii and class i skeletal pattern
conclusions pharyngeal airway dimensions, soft palate length, thickness, and position, and hyoid position are not significantly different between skeletal class i and class ii prepubertal children. results no significant difference in the upper airway, soft palate, and hyoid variables was found between the two groups (p > 0.05) and no correlation was found between anb difference and the other v...
متن کاملThree-dimensional evaluation of soft tissue change gradients after mandibular setback surgery in skeletal Class III malocclusion.
OBJECTIVE To evaluate whether mandibular setback surgery (MSS) for Class III patients would produce gradients of three-dimensional (3D) soft tissue changes in the vertical and transverse aspects. MATERIALS AND METHODS The samples consisted of 26 Class III patients treated with MSS using bilateral sagittal split ramus osteotomy. Lateral cephalograms and 3D facial scan images were taken before ...
