Does Topical Otic Drop Use at Time of Tympanostomy Tube Surgery Improve Outcomes When no Middle Ear Effusion is Present

Summary

To determine whether the use of topical otic drops intra-operative and post-operative during tympanostomy tube placement reduces the rate of tympanostomy tube occlusion and post-operative otorrhea (ear drainage) during the initial 4-week post-operative period in subjects with no middle ear effusion (fluid behind the ear drum) present at the time of surgery. A within subject controlled study design will be utilized to study this effect. Subjects with absent middle ear effusion who are receiving tympanostomy tube placement will receive a standard protocol of Floxin topical drops during surgery and after surgery in one ear. Selection of ear (right ear or left ear) will be randomized. The primary measured outcome will be the rate of tympanostomy tube occlusion within first 4 weeks postoperatively. The secondary measured outcome is the rate of tympanostomy tube otorrhea (drainage) within first 4 weeks postoperatively.
