The prospective study aimed to evaluate adenoid hypertrophy (AH) for its possible influence on the test. Moreover, nNO was assessed after adenoidectomy.
Healthy children and adolescents (n=38) were enrolled together with their diseased peers (n = 105) who were referred to the outpatient department due to chronic symptoms suggestive of AH. Their age ranged between 5 and 18 years.
