Ear drops after tube surgery: do they prevent blockage?
NCT ID NCT03655665
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether using antibiotic ear drops during and after ear tube surgery reduces the chance of tube blockage or ear drainage in children. Only 9 children took part, and each child received drops in one ear but not the other. The study was stopped early, so the findings are not conclusive.

What this could lead to
If it works, this could point toward a simple way to prevent ear tube blockage and drainage after surgery in children.
What could go wrong
This was a very small, early study that was terminated early, so results are limited and may not apply to all children. The drops may cause irritation or allergic reactions.
