Oropharyngeal and tongue exercises (myofunctional therapy) for snoring: a systematic review and meta-analysis

Abstract
Oropharyngeal and tongue exercises (myofunctional therapy) have been shown to improve obstructive sleep apnea. However, to our knowledge, a systematic review has not been performed for snoring. The study objective is to perform a systematic review, with a meta-analysis, dedicated to snoring outcomes after myofunctional therapy.
