The efficacy of orofacial myofunctional therapy in oral dysphagia accompanying temporomandibular dysfunction

Objective Patients with temporomandibular dysfunction (TMD) may develop oral-stage dysphagia (OD) in the chronic phase.Methods This study investigated the effect of orofacial myofunctional therapy (OMT) in individuals with TMD-related OD. Fifty-one patients aged 18–65 years with TMD-related OD were separated into three groups using a simple randomization method: the control group (n = 12) underwent patient education and a home-exercise program; additionally, to an exercise program the manual therapy (MT) group (n = 19) received MT; and the OMT group (n = 20) received the OMT program. MT and OMT were applied in two sessions per week for 10 weeks. The patients were re-evaluated after treatment and at 3 months.Results The OMT group showed the most improvement in jaw functionality, swallowing-related quality of life, pain, and dysphagia (p < .05).Discussion OMT was superior to MT and exercises alone in reducing dysphagia and improving the swallowing-related quality of life.
