Abstract: Objective Exploring the effects of snoring indicators and sleep quality in snoring patients through orofacial muscle functional training. Methods The study subjects were 80 patients diagnosed with simple snoring, upper airway resistance syndrome and obstructive sleep apnoea(OSA)admitted to Beijing Friendship Hospital, Capital Medical University. These patients were randomly divided into a control group(n=40)and an observation group(n=40). The control group received conventional interventions, while the observation group received training in oral and facial muscle function. The study compared the two groups on parameters related to snoring, sleep quality, daytime sleepiness, and anxiety and depression levels to assess the effectiveness of oral and facial muscle function training in reducing snoring. Results After 4 and 8 weeks of intervention, the snoring index(t=-2.353, -3.806; P=0.021, P<0.001), snoring loudness(t=-1.045, -2.602; P=0.299, 0.011)and total number of snores(t=-0.868, -2.545; P=0.388, 0.013)in the observation group were lower than those in the control group; the ESS score(t=-3.229,-6.925; P=0.002, P<0.001), PSQI score(t=-2.067, -4.446; P=0.042, P<0.001), SAS score(t=-2.366, -4.580; P=0.021, P<0.001), and SDS score(t=-5.103, -7.069; all P<0.001)in the observation group were lower than those in the control group. Conclusion In patients with snoring who underwent functional orofacial muscle training as an intervention, there was a significant decrease in snoring index, snoring loudness, and total number of snoring events with prolonged intervention. In addition, sleep quality and daytime sleepiness improved, and anxiety and depression were reduced. This method could be considered for wider promotion in the intervention of patients with snoring.
