In-Office Ear Tube Clinical Study

The Hummingbird research study is designed to evaluate ear tube placement in an office setting.  Children will be treated in the Ear, Nose, & Throat clinic with a topical anesthetic rather than the standard method of placing ear tubes in an operating room under general anesthesia.  Up to 200 children will be included in the study.

Basic Eligibility
  • Scheduled to undergo ear tube placement.
  • Ages 6 months through 24 months or 5 years through 12 years.
Consult a physician enrolling patients in the Hummingbird In-Office clinical study for study eligibility, potential benefits and risks.

Hummingbird® Tympanostomy Tube System



The Hummingbird® System is a disposable surgical tool designed to deliver a tube into the eardrum of patients during an ear tube placement procedure. The Hummingbird ear tube system was designed to place ear tubes in less time with fewer steps and without prolonged discomfort. Ask your physician what is best for your child.
