Answer

Use of aminoglycoside antibiotic eardrops in the presence of a perforation or ventilation tube may cause problems. Although this is controversial, many otolaryngologists believe that aminoglycoside eardrops may be ototoxic if they enter the middle ear. In these situations, using an alternative, nonototoxic topical preparation (eg, a fluoroquinolone, with or without a steroid) may be safer.
