The effectiveness of topical treatment in discharging ears with in-dwelling ventilation tubes. Topical ciprofloxacin/dexamethasone is superior to ciprofloxacin alone in pediatric patients with acute otitis media and otorrhea through tympanostomy tubes. Antibiotic treatment of acute otorrhea through tympanostomy tube: randomized double-blind placebo-controlled study with daily follow-up. Oral prednisolone is an effective adjuvant therapy for acute otitis media with discharge through tympanostomy tubes.
The efficacy and tolerability of topical treatment (both drops and spray) in the treatment of otorrhoea in those ears with ventilation tubes in-situ was studied. Sixty patients were randomised into two treatment groups. One group used an antibacterial/anti-inflammatory ear drop preparation (Otosporin) and the other group a similar preparation administered as an ear spray (Otomize). A 'blind' clinical assessment was made one and three weeks after commencing treatment. Both treatments (drops and spray) significantly improved patients' symptoms and signs after one week (p < 0.001). The spray was significantly easier to administer (p < 0.01) and caused less discomfort on application (p < 0.02). To determine whether topical administration of a corticosteroid improves resolution of acute tympanostomy tube otorrhea when combined with topical antibiotic drops.
                Randomized, patient-masked, parallel-group, multicenter trial of topical otic ciprofloxacin/dexamethasone versus topical ciprofloxacin alone in 201 children aged 6 months to 12 years with acute otitis media with tympanostomy tubes (AOMT) of less than or equal to 3 weeks' duration and visible otorrhea.
                Eligible patients were randomized to receive three drops of either ciprofloxacin 0.3%/dexamethasone 0.1% or ciprofloxacin 0.3% into the affected ear or ears twice daily for 7 days. Clinical signs and symptoms of AOMT were evaluated on days 1 (baseline), 3, 8 (end-of-therapy), and 14 (test-of-cure), and twice-daily assessments of otorrhea were recorded in patient diaries.
                The mean time to cessation of otorrhea in the microbiologically culture-positive patient population (n = 167) was significantly shorter with topical ciprofloxacin/dexamethasone than with ciprofloxacin alone (4.22 vs. 5.31 days; P =.004). This resulted in significantly better clinical responses on days 3 and 8 (P <.0001 and P =.0499, respectively). However, there were no significant differences between the two treatment groups in either the clinical response or the microbial eradication rate by day 14.
                Topical otic treatment with ciprofloxacin/dexamethasone is superior to treatment with ciprofloxacin alone and results in a faster clinical resolution in children with AOMT. The contribution of the corticosteroid in achieving a 20% reduction (1.1 day) in time to cessation of otorrhea is clinically meaningful and represents an important advance over single-agent antibiotic therapy. The role of routine antimicrobial treatment of acute middle-ear infections is under debate, because the efficacy of antimicrobials in the resolution of middle-ear fluid has not been unambiguously proven. Acute tube otorrhea is regarded as evidence of acute otitis media, and for methodologic reasons it was chosen to provide objectivity for diagnostics and outcome assessment. The objective of this study was to assess whether amoxicillin-clavulanate accelerates the resolution of acute tube otorrhea.
                Randomized, double-blind, placebo-controlled study in outpatient setting.
                Volunteer sample of basically healthy 6- to 72-month-old children with a tympanostomy tube. Eligibility required having acute tube otorrhea of <48 hours' of duration and no prior treatment within the last 2 weeks. The mean age of the participants was 25 months; they had a history of 3 episodes of acute otitis media (median), and 99% had manifestations of a concomitant respiratory infection. Of 79 randomized patients, 7 were withdrawn because of adverse events; 66 patients completed the study.
                Amoxicillin-clavulanate (N = 34; 45 mg/kg/d) or matching placebo (N = 32) for 7 days and daily suction of middle-ear fluid through tympanostomy tube.
                Duration of acute tube otorrhea and duration of bacterial growth in middle-ear fluid.
                The median duration of tube otorrhea was significantly shorter in amoxicillin-clavulanate than in the placebo group (3 vs 8 days). At the end of the 7-day medication period, tube otorrhea was resolved in 28 of 34 children receiving amoxicillin-clavulanate compared with 13 of 32 children on placebo (treatment-control difference 41%; 95% confidence interval, 20%-63%; number needed to treat, 2.4). The median duration of bacterial growth in middle-ear fluid was shorter in amoxicillin-clavulanate than in the placebo group (1 vs 8 days).
                Oral antibiotic treatment significantly accelerates the resolution of acute tube otorrhea by reducing bacterial growth in middle-ear fluid. To determine the efficacy of a short course of oral prednisolone as an adjuvant therapy for acute otitis media draining through tympanostomy tubes.
                In a randomized, double-blind, placebo-controlled study, children with acute discharge (<48 hours) through tympanostomy tubes received either prednisolone (2 mg/kg/d; n = 23) or placebo (n = 27) for 3 days. All children received amoxicillin/clavulanate (40/10 mg/kg/d) for 7 days. The children were examined daily at the study clinic until the drainage ceased.
                The median duration of otorrhea in the prednisolone group was 1.0 days (25% to 75% range, 1.0 to 2.0 days), compared with 3.0 days (25% to 75% range, 2.0 to 4.0 days) in the children receiving placebo (P <.001). The duration of otorrhea was </=2 days in 21 (91%) children in the prednisolone group, compared with 8 (30%) children in the placebo group (P <.001).
                Oral prednisolone appears to be modestly effective adjuvant therapy for acute otitis media with discharge through tympanostomy tubes in children. Further studies seem warranted to determine whether short-term use of steroids early during the course of acute otitis media would also reduce the duration of middle ear effusion in children with intact tympanic membranes.
The authors of this review have been unable to identify the most effective intervention or to assess the associated risks. Research is urgently needed into the effectiveness of oral versus topical antibiotics in this group of patients. Clinicians considering antibiotic treatment need to balance any potential benefit against the risks of side effects and antibiotic resistance.
