Treating Otitis Externa

I know the physicians on this board are loath to suggest treatments. However, being a physician myself (radiologist), and having definatively diagnosed my daughter’s condition as otitis externa (swimmers ear) what have others found to be the most affective treatment. For tonight it is going to be 50/50 vinegar and isopropol alcohol. However, there are a myriad of prescription treatments, some with multiple antibiotics and antifungals, and some fairly simple. What have others, including non physicians found effective for the treatment of moderate otitis externa?

I’ve found cortisporin otic suspension (or its generic) to be very effective.

I always make sure the patient doesn’t need a wick (due to severe swelling of the canal), otherwise all the drops in the world won’t help.
