Objective To retrieve, evaluate, and summarize the best evidence on voice rehabilitation for patients with dysphonia, so as to provide evidence for conducting voice rehabilitation training in clinic. Methods According to the 6S model of the evidence pyramid, we searched the clinical decision support system, guideline networks, databases, and websites of professional associations for evidence on voice rehabilitation in patients with dysphonia from January 1st, 2013, to May 16th, 2023, consisting of clinical decision making, guideline, expert consensus, evidence summary, systematic review, etc. Then the methodological qualities of the included studies were evaluated, the related evidence was extracted and integrated, its grade was evaluated, and its recommendation level was determined. Results A total of 15 studies were included, consisting of 2 clinical decisions, 3 guidelines, 2 expert consensus, 7 systematic reviews and 1 evidence summary, which were integrated into 4 major aspects of multidisciplinary collaboration, voice assessment, intervention measures, and follow-up on voice rehabilitation in dysphonia patients, concluding 17 pieces of evidence. Conclusion The summarized best evidence on voice rehabilitation for patients with dysphonia can guide clinical medical staff conducting voice rehabilitation training for patients, and promote their voice recovery.
