ABSTRACT
Aim: To assess the research gaps identified in a recent mapping review of orthognathic surgery through their evaluation by clinical experts, leading to a clinically relevant list of research gaps. This will guide future investigations of the topic, focusing on the outcomes of blood loss, infection, and relapse. Methods: The Delphi technique will be used to appraise the identified research gaps. The expert panel will include maxillofacial surgeons who regularly perform orthognathic surgery. Potential participants will be identified through various methods, including contact information from articles in the mapping review, nominations from peers, and social media platforms. Two rounds of surveys will be undertaken with Likert-type and open-ended questions to assess the clinical relevance of research gaps. For the second round, participants will receive a report of the results of the first round. Questions will be modified depending on the answers obtained in the first round. A consensus of 60% will be considered valid. Conclusions: Through this Delphi study, in a collaborative effort between researchers and clinical experts, a comprehensive understanding of the clinical relevance of research gaps in orthognathic surgery will be achieved. The outcomes will guide future investigations, ultimately improving the outcomes and practices in this field.
