Aims: The purpose of this study was to compare the changes of the pharyngeal airway space (PAS) in Class III patients who underwent mandibular setback by lateral cephalogram at three levels: Nasopharynx, oropharynx, and laryngopharynx. Materials and Methods: A series of twenty patients (14 males and 6 females) of age group 18–30 years, with clinically and radiographically diagnosed mandibular prognathism were treated with bilateral sagittal split ramus osteotomy to set back the mandible. Lateral cephalograms were taken 2 weeks and 3 months postoperatively for all patients. The width of PAS was measured at three different levels: Nasopharyngeal, oropharyngeal, and hypopharyngeal. Statistical Analysis: Paired t-test was used for comparisons between different parameters. Results: The width of hypopharynx reduced significantly (P < 0.05) after mandibular setback, which did not recover after 3 months. However, there was no significant reduction in the width of nasopharynx and oropharynx after surgery. Conclusion: Careful airway analysis should be performed when a mandibular setback surgery is planned because a significant correlation was found between the amount of mandibular setback and the reduction in the pharyngeal width.
