title: The influence of upper respiratory tract inflammation upon tubal function.
abstract: Eustachian tube function was examined in four patients (four ears) with a traumatic perforation of the tympanic membrane when they suffered from an upper respiratory tract (URT) infection or seasonal nasal allergy and after they had recovered. Although the tubal opening pressure did not show a distinct difference on the two occasions, the active ventilatory function was apparently impaired during the upper respiratory tract inflammation; particularly the negative middle ear pressure equalizing function, and was still impaired 2-3 weeks later after recovery from the upper respiratory tract inflammation. It is concluded that URT inflammation can affect tubal ventilatory function even in normal individuals.
