A simple method to prevent the obstruction of post-tympanoplasty ventilation tubes

摘要

The simultaneous insertion of a ventilation tube or grommet during tympanoplasty is a well-recognised practice among otologists. It is used to reverse atelectasis and to repneumatise the middle ear. A troublesome problem which can occur is post-operative, intraluminal grommet obstruction by blood or viscous mucoid secretions. Routine post-operative use of eardrops may help prevent grommet obstruction but cannot be administered after tympanoplasty when the ear canal is packed with dressings for up to three weeks post-operatively. In this article, we describe a simple method to prevent post-tympanoplasty grommet obstruction.
