The evolution of ototopical therapy: from cumin to quinolones

A radical change has occurred in the management of otorrhea over the past decade. Multiple studies have supported the efficacy of topical quinolones in the management of acute otitis media, acute otitis externa, and CSOM. For the first time, otolaryngologists have a scientific foundation on which to base our treatment protocols for these conditions. We no longer must rely solely on our clinical experience and prejudices. The quinolone drops have a superior safety profile and a broad antimicrobial spectrum, their overall cost is lower than the alternatives, and their convenient dosing schedule is tolerated well by most patients. When one takes all these factors into consideration, it becomes clear that topical quinolone therapy, with or without a steroid additive, is the treatment of choice for otorrhea in patients with a tympanic membrane perforation or ventilating tube. The development of ototopical medications has followed along the lines of Darwinian evolution, and the quinolone drops have clearly demonstrated the concept of "survival of the fittest."
