The aim of this study was to perform a systematic review on the dimensional stability of the upper airway (UAW) after orthognathic surgery. Methods: A systematic search in PubMed and Web of Science was performed, using the acronym PICO strategy and a guiding question to conduct the search. The research used the medical subjects headings (MeSH) terms and frequently used keywords, associated with the Boolean operators “and” and “or”. Main inclusion criterion used were: articles that evaluated, through CT scans, the upper airways of patients undergoing orthognathic surgery preoperatively and at least two times after the surgery. Results: A total of 3,490 articles from the two databases were found and subjected to the eligibility criteria. At the end, only eight articles were included. In a wide age range and balanced distribution between genders, different results in postoperative evaluations were observed, tending to return to the initial volumes. Conclusion: The UAW are extremely dynamic structures, however more studies with more controlled methods should be conducted to confirm these impressions.
