The size of an ear tube, also known as a tympanostomy tube or grommet, is quite small.
An ear tube, or grommet, is less than 2 mm tall, which is smaller than a match head (Tympanostomy tube - Wikipedia en.wikipedia.org › wiki › Tympanostomy_tube).
Ear tubes are tiny to allow them to be inserted into the eardrum to help drain fluid and equalize pressure.
