Conservative management of severe open bite and feeding difficulties in patient with noonan syndrome.

Noonan syndrome is a multiple malformation disorder with an autosomal dominant inheritance pattern. Congenital heart defects, short stature, thoracic deformities, short neck with webbing, hypertelorism, malocclusions, and feeding difficulties are some of the commonly observed clinical features. We report on a case of a patient with Noonan syndrome, severe open bite, associated feeding difficulties, and strong gag reflex, discussing conservative management with myofunctional therapy. Myofunctional therapy has demonstrated a successful outcome, reestablishing masticatory function and routine dental home care after an 18-month follow-up.
