Background and objectives: Otitis media with effusion is collection of fluid behind intact tympanic membrane. Otitis media with effusion usually coexists with the adenoid hypertrophy. The adenoid is a part of Waldeyer's ring; its basic function is thought to be antibody production. The aim is to identify the incidence of otitis media with effusion in children with adenoid hypertrophy. Methods: A prospective descriptive cohort study had been employed at Rizgari Teaching Hospital/ Erbil from January 2008 to July 2008. Summation of total 120 Child aged 3-12 years old were being conducted in the survey. All patients subjected for history, local physical examination, Information's recorded on a specially designed Questionnaire and proper investigations were done including lateral X ray of post nasal space, and audiological examination. Results: Among 120 patients age (3-12) years old with adenoid hypertrophy, 44 patients (36.7%) had OME, mean age was 6.5 years. Most common age group was (5-6) years (21) (47%). Conclusion: Adenoid Hypertrophy (AH) can be relevant in the pathogenesis of otitis media with effusion (OME) due to its anatomic position.

Methods: This prospective study included 71 children aged 3-10 years old attending Rizgary Teaching Hospital for adenotonsillectomy between August 2013 to January 2014. Questions about upper airway obstruction symptoms were directed to parents and patients. Tympanometry and plane radiological study of lateral soft tissue of the neck were done for each case. Tympanometric type A and C1 were considered normal while B and C2 as abnormal. The adenoid size was measured by using adenoidal/nasopharyngeal ratio. Results: Of 71 children (142 ears), 20 children (40 ears) had gross adenoid enlargement, of which tympanometry was found to be normal in 75% and abnormal in 25%. In 28 children (56 ears) with moderate adenoid enlargement, tympanometry was normal in 78.6% and abnormal in 21.4%. Twenty three children (46 ears) had minimal adenoid enlargement, in which tympanometry was normal in 91.3% and abnormal in 8.7%. Conclusion: The study showed that adenoid size in children had an effect on tympanometric readings. Although the incidence of abnormal tympanometry was higher with the increased adenoid size but it was statistically non-significant.
