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...

Objective: To determine the effect of orthognathic surgery on soft tissue in Class IIIpatients and to compare the results of different surgical techniques. Materials and Methods: Forty-eight Class III adult patients were included in the study to assessthe changes in the soft tissue after orthognathic surgery. Nine patients were treated with Maxillary Advancement (MA), seven patients were treate...
متن کاملSoft and hard tissue changes in Class III patients treated by bimaxillary surgery.
A cephalometric study of 17 non-growing dentate Class III subjects treated by bimaxillary surgery was undertaken to assess the results of treatment and to evaluate the correlation between soft and hard tissue change. It was concluded that: (i) the orthognathic profiles achieved were brought about by a combination of maxillary advancement and mandibular setback; (ii) a strong correlation in the ...
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 ...
متن کاملA more accurate method of predicting soft tissue changes after mandibular setback surgery.
PURPOSE To propose a more accurate method to predict the soft tissue changes after orthognathic surgery. PATIENTS AND METHODS The subjects included 69 patients who had undergone surgical correction of Class III mandibular prognathism by mandibular setback. Two multivariate methods of forming prediction equations were examined using 134 predictor and 36 soft tissue response variables: the ordi...
