A survey of the pattern of usage of ototopical preparations in out-patients of the ENT department of a Dutch University Hospital has been performed. Data on clinical presentation and previous treatment of the patient, otoscopic results, prescribed current treatment and, if available, results of microbiological examination were collected. One-hundred and twenty-one evaluable patients were prospectively included. For 20% of the patients it concerned a first manifestation of the symptoms, 35% had a recurrence after a period free of symptoms and in 37% it concerned patients with persisting symptoms despite treatment. Forty-five percent of the patients' ears concerned had an intact tympanic membrane, in 25% a perforation was present and in 12% middle ear ventilation tubes were in situ. Thirty-five percent had already received previous treatment with ear drops. The species most often isolated was Staphylococcus aureus, followed by Pseudomonas aeruginosa. A wide range of products were prescribed. While previous treatment occurred with combination preparations, for current prescriptions, ofloxacin was most often used. Most patients received 2 to 3 drops 3 times a day for 7 to 10 days, which is in accordance with recommendations in the literature. Potentially ototoxic substances are regularly used in daily practice. Ofloxacin is widely used even thought it is not registered for this indication in the Netherlands and the development of resistance has to be taken into account. A new policy based on this survey is proposed, which will reduce the number of different preparations used and will eliminate ofloxacin from first the treatment.

The efficacy and safety of 0.3 per cent Ofloxacin otic solution (OFLX) 6 drops twice daily was compared with those of oral Amoxycillin 500 mg three times daily plus 1 per cent Chloramphenicol ear drop at 3 drops three times daily (AMOX + CRP) in a two-week treatment of chronic suppurative otitis media (CSOM) with acute exacerbation. 80 adult patients were enrolled in a prospective, randomized, investigator-blind study at the outpatient ENT service of Chulalongkorn University Hospital. The most common pathogens isolated at the pretreatment visit were Staphylococcus aureus (30.3%) and Pseudomonas aeruginosa (24.7%). The susceptibility of all the pathogenic isolates to ofloxacin, amoxycillin and chloramphenicol were 96.4, 57.1 and 51.8 per cent respectively. The overall response expressed as an improvement or cure of otalgia, otorrhea and middle ear mucosal inflammation was recorded. It revealed that the improvement rate of the OFLX-treated patients was better than that of AMOX + CRP-treated, but was not statistically significant. However, the cure rate was significantly better in OFLX-treated than in AMOX + CRP-treated groups in terms of painless (p = 0.05) and dry (p < 0.001) ears. Ototoxicity was assessed by an elevation in bone conduction threshold (BC) and/or speech reception threshold (SRT) of greater than 5 dB or a presence of high tone hearing loss resulting from treatments. A significant decrease in BC and SRT was revealed in OFLX-treated ears (p < 0.0001; p = 0.002 respectively) but a significant elevation of BC was found in AMOX + CRP-treated ears (p = 0.007). The ototoxic rate was significantly higher in AMOX + CRP-treated than in OFLX-treated ears whether assessed by BC (p < 0.001) or SRT (p = 0.03). In conclusion, OFLX was more effective and safer than AMOX + CRP in the treatment of CSOM with acute exacerbation.
