Adenoid hypertrophy is mainly seen in infants and young children. Children with adenoid hypertrophy often also have enlarged tonsils. Therefore, it is important to ask if the patient breathes with their mouth open, snores, or has episodes of breath-holding. In older children, a nasal endoscopy can be performed to find that the adenoids block two-thirds or even up to three-quarters of the posterior nasal aperture. For smaller children who may not cooperate, imaging studies such as nasopharyngeal CT, X-rays, and lateral films can be used to detect adenoids. In the nasopharynx, the imaging will show the presence of soft tissue with clear boundaries from the surrounding areas.
