Three-Part Question:
[In children with suppurative otitis media] is the [topical application of antibiotics superior to systemic antibiotc treatment] at [decreasing purulent discharge and time to clinical recovery]?
Clinical Scenario:
A three year old girl with the first episode of a febrile unilateral otitis media with purulent discharge and otalgia is brought to Children's Emergency. As usual you would prescribe oral amoxicillin but the consultant who happens to stand next to you when filling out the prescription advises you to use antibiotic eardrops instead. They would just be better.

Standard-Searchterm: PN136.sx
Outcome:
Altogether 1562 papers were found in Medline, 50 in the Cochrane Library and 90 in Maternity and Infant Care, of which in total 4 were relevant. One of those compared topical ofloxacin for chronic suppurative otitis media (CSOM) against a not defined "historical-practice control" or "current-practice control" respectively and was therefore excluded. All three remaining papers addressed either chronically discharging ears or acute otitis media in children with tympanostomy tubes. No randomized clinical trials including children with acute purulent otitis media and spontaneous eardrum perforation were found.

Systemic Review of RCTs Primary : Resolution of CSOM at 1 to 2 weeks and at 2-4 weeks according to the investigators¡¯ criteria Topical quinolone antibiotics better than systemic antibiotics at 1-2 weeks, 95% confidence interval (CI) 1.88 to 5.49, No statistically significant benefit was seen at 2-4 weeks for topical nonquinolone antibiotic over systemic antibiotics Adults included in patient groups, 4 trials with adults only, unknown number of treated children;
CSOM definitions and severity varied; Methodological quality varied;
Range of different applications and groups of systemic antibiotics (i.m., oral, i.v.);
Small numbers (N=31) for topical non-quinolones
Author Commentary:
Aural toilet was not discussed in several trials, but regularly performed in others. It surely appears to be a useful procedure in order to increase local concentration of the applied ototopics at the very region of interest, but this issue as well as safety of application of those antibiotics were not subject of this BET.

Some national drug authorities (e.g. Australia and USA) have not yet approved or have limited the use the of ototopical quinolone-preparations.

No published trials concerning children with acute otitis media and spontaneous perforation of the eardrum have been found. In children with chronic suppurative otitis media or tympanostomy tubes the topical application of antibiotics may have a better outcome than systemic antibiotics. This may be beneficial especially if children are refusing to take oral antibiotics, vomit or have an uncertain enteral absorption for other reasons. National approvals and local guidelines still have to be considered.
Bottom Line:
No published evidence was found to answer the initial question, national approvals and local guidelines should be followed.
