ASSESSMENT OF FORMATION OF FACIAL SOFT TISSUES PROFILE AT DIFFERENT TYPES OF MYOFUNCTIONAL DISORDERS
Purpose: to analyze the peculiarities of facial profile formation of 4–6-year-old children with myofunctional violations. Materials and methods – 35 digital photos and teleroentgenograms in lateral projection by Viasys A.D 1991 method were studied.Results: Considering age-dependentdominance variousof different myofunctional violations the profile assessment was carried out depending on a type of the revealed violation.Patients with prolonged sucking function – retropositionof lower jaw and expressed retrogenic convexity of the lower third of the face, impaired swallowing function – anteprotrusion of the upper lip and change of the lower third of the face, impaired speech function – convex facial profile and upper lip anteposition, impaired respiratory function – convex profile and retrogenic convexity of the lower third of the face. All other assessed parameters have had slight deviations from the norm and did not have significant differences.Conclusion: As profilometric analysis has shown regardless of type of myofunctional violations some characterizing features have been revealed. Early detection of which is undoubtedly an indication for active orthodontic treatment.
