Prophylactic ciprofloxacin drops after tympanostomy tube insertion.

OBJECTIVE To evaluate the effectiveness of prophylactic ciprofloxacin drops in decreasing the incidence of post-tympanostomy otorrhea, and the relation between middle ear content and post-tympanostomy otorrhea. METHODS One hundred and fifty patients aged 3-14 years underwent tympanostomy and tube insertion at the Prince Rashid Ben Al-Hasan Hospital, Al-Husn, Jordan during the interval between February 2000 to January 2003. The patients were randomized into 3 groups: group 1 (control group) received no antibiotic drops, group 2 received a single dose of ciprofloxacin drops intraoperatively and group 3 received an intraoperative dose followed by 5-day postoperative course. RESULTS Application of topical ciprofloxacin after tympanostomy tube insertion was associated with a significantly lower incidence of early post-tympanostomy otorrhea. The rate of otorrhea for the control group was 16.5% and the treatment groups were (group 1) 8.4%, (group 2) 8.2% and p=0.011. A single dose of antibiotics was effective when patient's middle ears were dry or had serous effusions. For those whose ears had mucoid or purulent content a 5-day course was indicated. CONCLUSION Topical administration of a single dose of ototopical ciprofloxacin after surgery is an effective treatment for the prevention of early post-tympanostomy otorrhea, and a prolonged course (5 days) may be indicated for those whose ears had purulent or thick mucoid contents, and the content of middle ear are important in predicating postoperative otorrhea.
