Which otic preparation should be avoided if tympanic membrane perforation is suspected?

• A. Aminoglycoside-containing otic preparation (e.g., Neomycin-containing drops)
• B. Ciprofloxacin/dexamethasone
• C. Miconazole ear drops
• D. Ofloxacin drops

Answer: (A)

Ototoxicity risk when the tympanic membrane is compromised is the key idea. Aminoglycoside-containing ear drops, such as neomycin-containing preparations, can travel through a perforated membrane into the middle ear and then damage the inner ear’s hair cells, causing irreversible sensorineural hearing loss or vestibular dysfunction. This is why they should be avoided when a perforation is suspected. In contrast, fluoroquinolone drops like ciprofloxacin/dexamethasone or ofloxacin drops are safer options in this situation because they treat the common pathogens effectively without the same ototoxic risk. Miconazole ear drops are antifungal and not first-line for bacterial infections, but the critical point here is to avoid aminoglycosides due to the potential for inner ear injury if the membrane is perforated.
