The Effect of Orofacial Myofunctional Therapy on Neuromuscular Outcomes and Orofacial Function in Children and Adolescents in Estonia
Sponsor: Tartu University Hospital
Summary
The aim of the present study is to evaluate the effects of semi-standardized myofunctional therapy on the functional and neuromuscular characteristics of the orofacial system in children and adolescents aged 7-14 years using a longitudinal study design and a unified assessment protocol. Myofunctional therapy is a treatment method for functional disorders of the oral, lingual, and facial regions. The study approaches the orofacial system holistically by linking functional characteristics with anatomical structures, including palatal morphology and skeletal and dentoalveolar occlusal relationships, while also considering the impact of treatment adherence on outcomes. Participants' orofacial functions and neuromuscular characteristics will be assessed before, during, and after therapy using standardized clinical measurements. The study will analyze the dynamics of changes, individual variability, and associations with craniofacial phenotype and treatment adherence. Despite the widespread use of myofunctional therapy in Estonia, systematic evidence regarding therapy effectiveness, treatment dynamics, and factors influencing outcomes is limited, and unified assessment and intervention standards are lacking. The study aims to address this knowledge gap and support evidence-based implementation of myofunctional therapy, clinical decision-making, and healthcare resource planning.

Interventions
Semi-standardized Orofacial Myofunctional Therapy
Participants receive semi-standardized orofacial myofunctional therapy over an 8-month period, consisting of 8 therapy sessions at approximately 4-6-week intervals. Individually tailored exercises target tongue strength and mobility, lip strength and closure, swallowing pattern, tongue resting posture, nasal breathing and reduction of mouth breathing, and other orofacial functional patterns. Exercises are practiced under therapist supervision and performed at home once daily according to an individualized exercise program. Simple non-invasive aids, including a spatula and a button attached to a string, may be used during exercises. The intervention corresponds to routine clinical care and does not involve invasive or painful procedures.
