A randomized prospective comparison of two methods of administering topical treatment in otitis externa.

Ten patients with bilateral moderate or severe otitis externa were studied. Following aural toilet each patient was subjected to two different treatments: one ear had alternate day dressings containing a topical antibiotic/steroid mixture, while the external canal of the other was filled with the same topical preparation (sump filling). Improvement in the severity of the otitis externa was assessed after 1 week. 9 out of 10 ear canals improved in each group. An estimate of the relative cost of each treatment was made and sump filling was found to be less expensive. The results suggest that sump filling is a low cost alternative to standard treatment in moderate and severe otitis externa.
