Evaluation of Hyoid Position in Children of 7-11 Years Old with Ankyloglossia in Lateral Cephalometic Radiographs
Introduction: Ankyloglossia is an anatomic developmental anomaly determining by thick and short, fibrotic ferenum. Tongue changes have severe effects on occlusion and oropharyngeal structures. The aim of this study was to evaluate the position of hyoid in children 7-11 years` old with ankyloglossia in lateral cephalometric radiographs.
Materials and Methods: 30 radiographs of children with ankyloglossia with mean age of 9.8 and 30 radiographs of control group were chosen and matched in terms of age, sex, class of malocclusion and growth pattern. The measurements of hyoid position were done (C3-RGN, C3-H, H-RGN, HP) and analyzed with paired t-test under SPSS-15 software.
Results: The means of C3-RGN, C3-H, H-RGN, HP were 66.2, 30.9, 33.4, 3.2 and 7.45, 36.8, 34.1, 68.6 in ankyloglossia and control groups respectively. Lower amount of measurements were statistically significant (p-value<0.05).
Conclusion: Size and position of hyoid in children with ankyloglossia show more posterior- superior Position than healthy children.
