Experimental studies on the relationship between maxillary sinus ventilation and various obstructions of the nose and nasopharynx

Volume: 27 - Issue: 1

Firstpage: 37 - Lastpage: 43

C. Bachert - U. Ganzer

The relationship of the nasal and the antral ventilation was studied with a plastinated
model of a human nose. The effects of adenoidal hyperplasia and septal
deviations on the antral ventilation were measured. It could be demonstrated that the
aerodynamic effect of an obstruction within the nasal cavity largely depends on the
localisation of the stenosis (anterior or posterior to the maxillary ostium). Additionally,
the influence of an ostial obstruction on the antral ventilation was examined in
dependence on the nasal ventilation. We were able to demonstrate that the antral
pressure variations not only reflect the ostial function but as well the total aerodynamics
of the upper respiratory tract. From this point of view we discuss diagnostic and
therapeutic conclusions.
