Abstract The adenoid hyperplasia is a common problem during childhood. Adenoid is a subepithelial tissue which is located in nasopharynx and is considered as a part of Waldeyer's ring. It has a significant value in immunity as it produces immunoglobulin types IgG, IgA, and IgM. It reaches the peak of its size between 3-8 years of age then starts to regress. The main purpose of this study is to find the accurate way of pre-operative assessment of adenoids size. Fifty patients aged between 4-10 year were included in this prospective descriptive study, they have a chief complaint of nasal obstruction and snoring. The results of this study showed that endoscopic assessment of adenoids is much superior to radiological one.
