[Usefulness of posterior electrorhinomanometry in the study of nasal and nasopharyngeal resistance in children aged 5 to 10].

Nasal passages constitute the physiologic airway. Impaired nasal breathing leads to various disease states. History taking and rhinoscopic examination are not sufficient for the complete evaluation of nasal respiratory patency. The authors present a case for introduction of posterior rhinomanometry (own modification) as an objective method in studying nasal patency in children, 127 healthy children (aged 5-10 years) were examined. Nasal resistance to air flow was measured. Posterior rhinomanometry was used in 198 children with impaired nasal patency of various causes. The results obtained in this study are reproducible and in accord with data in the literature. Children between 5 and 10 years of age cooperate well with the examiner. The authors find posterior rhinomanometry suitable for examination of children within this age group.
