If you put a qtip in one ear could it come out the other?

It is not possible for a Q-tip to come out of the other ear. The Eustachian tube, which connects the middle ear to the back of the throat, is too narrow to allow a Q-tip to pass through. Additionally, the structure of the ear canal prevents a Q-tip from being inserted deeply enough to reach the Eustachian tube.

Inserting a Q-tip too deeply into the ear can damage the eardrum and cause hearing loss. If you need to clean your ears, it is best to use a soft cloth or a cotton swab moistened with water or saline. Never insert anything sharp or pointed into your ear.
