Abstract:

During the combined orthodontic-orthognathic treatment of orthopaedic Class Ⅲ patients, attention needs to be paid to the impact of receding mandible on the airway during orthognathic surgery, thus reducing the probability of medically induced obstructive sleep apnoea syndrome. Effective preoperative prediction of airway changes and selection of the correct procedure are essential in the overall treatment plan. This article reviews structural characteristics of the upper airway in patients with skeletal Class Ⅲ malocclusion, advantages and disadvantages of commonly used methods for measuring the upper airway, changes in the airway after orthognathic surgery and available methods for airway prediction.

Key words: skeletal class Ⅲ malocclusion, upper airway, orthognathic surgery
