Abstract

Background and Aim: Severe mandibular deficiency may result in reduced oropharyngeal airway (OAW) dimensions and predispose patients to respiratory dysfunctions such as obstructive sleep apnea and snoring. The aim of this study was to assess the effects of functional treatment on anteroposterior and vertical dimensions of airway in skeletal class III patients with mandibular deficiency.Materials and Methods: This interventional study was done on lateral cephalogerams of 25 mandibular deficient patients with average 9.9 years of age who were treated with modified activator appliance. Digitized cephalograms were traced and analyzed by ViewBox version 3,1,1,3 cephalometric software. Paired t-test was performed to evaluate pre- and post-treatment data.Results: Skeletal sagittal discrepancy was improved with decreasing ANB angle from 6.68o to 4.48o and increasing SNB angle from 74.48o to 76.78o (p<0.001). Anterior-posterior dimensions of nasopharynx were increased from 19.64 to 21.52 mm (P=0.021), Anterior-posterior dimensions of oropharynx increased in AW2 and AW4 (p<0.05) but in AW3 increasing from 11.26 to 12.27 mm was not statistical significant (p=0.091). Anterior-posterior dimensions of hypopharynx increased from 16.54 to 19.22 mm (p<01001). Vertical dimension of airway increased from 60.73 to 64.79 mm (p<0105).Conclusion: Treatment of mandibular deficient patients with functional appliances improved mandibular position as well as airway dimensions.
