Définition de la «ventilation nasale optimale» Volume 74, issue 2, 76e réunion scientifique de la S.F.O.D.F. – La dimension verticale (1re partie)


The exchanges of heat, whose nasal mucosa is the instrument, play indirectly a prominent role in human brain thermoregulation. Their alteration by nasal obstruction is the source of sleepy and behavioral problems : these disorders cease as soon as exclusively nasal ventilation at rest and when sleeping is re-established.

From these data, «optimal nasal ventilation» is put forward as an operative physiological definition. They allow a better understanding of malocclusion etiology. They specify the objectives to be reached thanks to dentofacial orthopedics.
