A child with otitis externa has severe swelling of the external auditory canal after 2 days of ototopical antibiotic/corticosteroid drops. What is the next step in treatment?

• A. Insert a wick into the external auditory canal.
• B. Irrigate the external auditory canal with saline.
• C. Order systemic corticosteroids.
• D. Prescribe an oral antibiotic medication.

Answer: (A)

When the external auditory canal is severely edematous, topical drops can’t reach the deeper inflamed tissues. Placing a medicated wick into the canal creates a conduit that bypasses the swelling, allowing the antibiotic and corticosteroid to be delivered throughout the canal and even toward the tympanic region as needed. The wick stays in place to maintain continuous drug delivery and helps relieve pressure from the swollen canal, speeding resolution and reducing pain. Irrigation isn’t ideal here because a swollen, inflamed canal is painful to irrigate and the meds won’t distribute effectively without a path; systemic corticosteroids aren’t the primary next step since the issue is poor topical penetration, and oral antibiotics alone may fail to treat the infection adequately without better topical access.
