Abstract

Background & Objectives: Adenoid hypertrophy is one of the commonest etiology for otitis media with effusion (OME). OME is a leading cause of diminished hearing in children younger than 12 years. This study compares the efficacy of adenoidectomy on OME in patients with different grades of adenoids and the connection between different position of adenoids and middle ear effusion. Methods: This is a prospective study done on 120 pediatric patients (2 to 12 years) presented with chronic otitis media with effusion and adenoid hypertrophy from 2017 to 2019. Adenoid size was graded and correlated with the type of tympanometry. All the cases were subjected to adenoidectomy with myringotomy and were observed every 3 months. Preoperative and postoperative data were collected and comparison was made to evaluate whether adenoidectomy with myringotomy is sufficient on management of OME. Results: Adenoid tissue grading showed majority of population remained in Grade III (45%) and Grade C (56.67%). There is a highly significant relation between higher adenoid grade and type B tympanometry. This study showed significant association between grade III and grade C adenoid hypertrophy and otitis media with effusion when compared with other grades of adenoid hypertrophy. This suggests that increasing grade of adenoid hypertrophy is important predictor in establishment of otitis media with effusion in patient with adenoid hypertrophy. After adenoidectomy majority of tympanometry curve was shifted from type B to type A. In case of Grade III, type B tympanometry reduced from 45 to 11 (83% to 20%) in right ears; 49 to 7 (90% to 12%) in left ears. Again, in case of Grade C, type B tympanometry reduced from 55 to 6 (80% to 8%) in right ears; 58 to 5 (85% to 7%) in left ears. This change was significant. The greater the size of the adenoid, after adenoidectomy, more improvement noticed in tympanometry curve. Conclusion: This study may not be the actual picture of overall situation due to many limitations. Still it can be concluded that enlarged adenoids has a definite role in causing OME. This research also shows a benefit of adenoidectomy in the removal of middle ear effusion in children with OME. To efficiently assess the efficacy of adenoidectomy for otitis media with effusion in children, future research is needed.
