Eustachian Tube Function in OME Patients with Cleft Palate: Special Reference to the Prognosis of Otitis Media with Effusion

Eustachian tube function was investigated in two groups of cleft palate patients who had otitis media with effusion. One group consisted of 16 ears that healed after one ventilatory tube insertion, the other consisted of 33 ears that needed repeated tube insertion and did not heal in 2 years. The latter group was characterized by low opening pressure and inability to sustain lower middle ear positive pressure. This decrease force in the Eustachian tube was considered to be related to the prognosis of otitis media with effusion in patients with cleft palate.
