Impact of adenoid hypertrophy on the open bite in children.

Nasal obstruction caused by adenoid hypertrophy can lead to malocclusion. The research material consisted of children aged 7-12 years with adenoid hypertrophy qualified for adenoidectomy. On the basis of the conducted tests (laryngological, orthodontic, pediatric), the occurrence of open frontal bite in children with pharyngeal tonsil hypertrophy, in particular in boys, was confirmed in comparison to children without hypertrophy correctly breathing through the nose.
