How do you know when you need adenoids out?

Really blocked nose. Adenoids disappear before adulthood, so adults don't need adenoidectomy. If a child has chronic stuffy nose, and endoscopy in the office, or xray shows enlarged adenoids, or sleep apnea, then adenoidectomy should be considered.
Symptoms. Frequent throat infections can cause the adenoids to become enlarged. Enlarged adenoids can obstruct breathing and block the Eustachian tubes, which connect middle ear to the back of the nose. Clogged Eustachian tubes cause ear infections that can jeopardizehearing and respiratory health.Adults can also present with the same symptoms.Sometimes endoscopy and CT needed to confirm adenoidal presence.
