Abstract
The ventilatory function of the Eustachian tube was assessed in a group of infants and children with cleft palate, some of whom had received palatal repair. Those whose palates had been repaired were better able, in general, to equilibrate applied positive middle ear pressures than were those with open clefts. In many of the patients whose palates had been repaired, the results of Eustachian tube function studies were similar to those in normal subjects. Differences in Eustachian tube ventilatory function are assumed to be related to differences in tubal compliance. Excessive compliance probably results in, or exaggerates, functional Eustachian tube obstruction. Improvement in tubal function following palate repair is probably related to factors resulting in greater tubal stiffness.
