Objective:To systematically search, evaluate, and summarize evidence-based findings related to postoperative oral health management for orthognathic surgery patients, with the goal of providing clinical care professionals with evidence-based guidance for postoperative care, infection prevention, and functional recovery.Methods:Using the "6S" evidence hierarchy model, a systematic search was conducted in databases such as UpToDate, BMJ Best Practice, DynaMed, The Cochrane Library, World Health Organization (WHO), National Institute for Health and Care Excellence (NICE), Guidelines International Network (GIN), Registered Nurses′Association of Ontario (RNAO), Chinese Stomatological Association (CSA), American Association of Oral and Maxillofacial Surgeons (AAOMS), PubMed, and Scopus. The search included literature on postoperative oral health management for orthognathic surgery patients, such as guidelines, clinical decision-making tools, expert consensus, evidence summaries, and systematic reviews, covering publications from database inception to November 12, 2024. Two researchers independently assessed the quality of the included literature and extracted, summarized, and synthesized the evidence.Results:A total of 18 studies were included, consisting of 7 guidelines, 7 systematic reviews, 2 expert consensus documents and 2 randomized controued trials. Twenty-two best evidence statements were summarized, addressing six key areas: oral hygiene and infection prevention, wound care, oral functional recovery, dietary and nutritional support, oral comfort management, and long-term oral health maintenance.Conclusions:This study provides a comprehensive summary of the best available evidence for postoperative oral health management in orthognathic surgery patients. It offers theoretical support for clinical nursing practices and evidence-based recommendations for postoperative care specific to this patient population.
