title: Tympanostomy tube obstruction related to ototopical drug therapy.
abstract: Obstruction of tympanostomy tubes is a potentially significant complication, sometimes requiring replacement of the nonfunctioning tube. Early blockage can occur secondary to bleeding during the tube placement procedure. Delayed obstruction is usually caused by inspissated secretions or epithelial casts. We briefly report our treatment of 9 cases of delayed ventilation tube obstruction that were associated with the use of an ototopical antibiotic/steroid suspension.
