ABSTRACT
The objective of this study was to evaluate the permeability of the airways in patients undergoing a mandibular orthognathics surgery by skeletal class III occlusion. The study was carried out in 2004, in the Department of Buccal and Maxillofacial Surgery, in the Division of Professional Studies of the UNAM School of Dentistry. The design of the study was transversal and descriptive. Ten patients who received mandibular reduction surgical treatment were selected randomly, their cephalometrics were distributed in two groups. Group I with preoperative cephalometrics and Group II with postoperative cephalometrics. Measurements were analyzed with the McNamara procedure to value permeability of the superior and inferior pharynx and the results obtained in the two groups were compared with the average values. The observed alterations of permeability of postoperative airways were 50% in the superior pharynx and 10% in the inferior pharynx. This is a simple method which allows the changes in the anteroposterior dimension of the oropharinx to be studied in patients subjected to mandibular reduction.
