The orthognathic surgery is a branch of Oral and Maxillofacial Surgery that cares the dental-facial changes. Its main objective is to reestablish proper dental occlusion and facial harmony by modifying the position, size and shape of the facial bones. Besides fixing dental-facial deformities class II in patients with maxillary and mandibular anteroposterior deficiency, the maxillo-mandibular advancement surgery significantly increases airspace. The objective of this paper is to report the variation of the area and the volume of the airway from the computed tomography cone beam image analysis, of a female patient, 18 years, class II with bi-retrusion maxillo-mandibular submitted to orthognathic surgery. In this study it was observed that all the figures for the total area, the volume and the largest area of constriction of the airways increased postoperative periods of 15 days and 6 months with the values found before surgery. However, postoperative periods of 1 and 3 years, it was possible to realize a decrease of these values except the largest constriction area which obtained an increase in the last evaluation period. However, despite the decrease of these values, there was still a satisfactory gain when compared to the preoperative period.
