Hearing improvement after adenoidectomy v/s adenoidectomy with grommet insertion in cases of otitis media with effusion-randomized control trial in kles dr. Prabhakar kore hospital, belagavi

Abstract

BACKGROUND Adenoids are a lymphoid tissue mass lying within the mucous membrane of the roof and posterior wall of the nasopharynx and may affect breathing in the upper airway. Eustachian tube maintains middle ear ventilation and is lined by ciliated, pseudo stratified columnar epithelium same as that of respiratory tract lining which extend as far as anterior part of middle ear cavity. Upper respiratory tract infection (URTI) disrupts the mucocilliary action of ET due to oedema as well as loss of cilia which can lead to Otitis Media with Effusion (OME). OME is the chronic accumulation of mucus within the middle ear and sometimes the mastoid air cell system. Despite a majority of cases resolving spontaneously some may have persistent hearing loss causing delay in development of language, social behavior, learning difficulties which will affect the academic performance of a child. Surgical treatment options include grommet (ventilation or tympanostomy tube) insertion, adenoidectomy or both. Grommet insertion relieves the symptoms of the effusion such as the conducting hearing loss and episodes of otitis media as well as improving the ventilation of the middle ear.Adenoidectomy is thought to improve middle ear function by removal of mechanical obstruction as well as removing or reducing the reservoir of opportunistic pathogens.In our study, we used pure tone audiometry and tympanometry to meaure the post operative hearing improvement in patients of otitis media with effusion having undergone either adenoidectomy or adenoidectomy with grommet insertion.

OBJECTIVE To compare hearing improvement after adenoidectomy v/s adenoidectomy with grommet insertion in cases of otitis media with effusion
