Özet

Cephalometric Studies show significant gender differences in the size of the pharyngeal airway space. This Study aimed to investigate and compare morphologic changes after mandibular setback or two-jaws surgery oil the pharyngeal airway in men and women using computed tomography (CT). The sample included 34 women and 13 men diagnosed with Class III skeletal deformities, who had been treated by mandibular setback or bimaxillary Surgery (maxillary advancement and mandibular setback). Anteroposterior, lateral and cross-sectional area dimensions of the airway, at the level of soft palate and base of tongue, were measured pre- and postoperatively on CT images. In the mandibular setback group, the anteroposterior and cross-sectional area of the pharyngeal airway at the level of the soft palate and base Of tongue were significantly reduced for men or women (P < .05). In the two-jaws surgery group, only midsagittal anteroposterior dimensions at the same levels were significantly decreased for men or women (P < .05). The difference between any values measured between men and women who received bilateral sagittal split ramus osteotomy setback surgery or two-jaws surgery for the treatment of class III anteroposterior discrepancy were not statistically significant (P > .05). This study Suggests that oropharyngeal airway measurements, important for airway patency, do not demonstrate sex dimorphism.
