Otitis media with effusion (OME) due to chronic adenoiditis is one of the most common chronic otological problems dealt by otorhinolaryngologists. It is defined as the chronic accumulation of mucus within the middle ear and sometimes the mastoid air cell system. The role of adenoids in the pathogenesis of OME is much debated. Several mechanisms have been described in literature for the pathogenesis of OME, the most accepted being displacement of eustachian tube orifice. The main objective of the study is to study the association between size of adenoids and occurrence of otitis media with effusion and to evaluate the grades of adenoid hypertrophy by lateral neck radiograph. This study gives support to the concept that the Adenoidal-nasopharyngeal ratio (ANR) is a conventional and convenient radiological parameter for determining whether adenoid hypertrophy is clinically significant or not, rather than the size of adenoid or the size of the nasopharynx alone
