Ear tube insertions are a common medical procedure used to treat persistent ear infections or fluid buildup in the middle ear. During the procedure, a doctor places small tubes, called tympanostomy tubes, into the eardrum. These tubes help to ventilate the middle ear and prevent the accumulation of fluids, which can lead to infections and hearing loss. The insertion is typically performed under general anesthesia in children or local anesthesia in adults. The procedure is quick, usually lasting about 15 to 20 minutes, and most patients can return home the same day. After the tubes are in place, they usually stay for several months before falling out on their own.
