The influence of ventilating tubes on the surgical treatment of atelectatic ears.

Forty children and 53 adults having 111 atelectatic ears were operated on and followed up. All patients underwent a tympanoplasty operation, while 27 patients underwent concomitant various mastoid operations. A ventilating tube was inserted in 55 out of the 111 atelectatic ears, while in 56 ears the tympanoplasty was left without a ventilating tube. After an average of 53.1 months of post-operative follow-up we found that all ears were adequately aerated as long as a ventilating tube was in place. However, at the final check, once all ventilating tubes extruded, it was found that insertion of a ventilating tube at operation did not change the natural evolution of the atelectatic condition after surgery. Our conclusion is that the only way to overcome the atelectatic prone condition is to reinsert a ventilating tube whenever atelectasis reformation occurs.
