Otitis media, Adenoidectomy, Pure tone audiometry


Background: Otitis media with effusion (OME) is an inflammatory disorder of the middle ear that is characterised by the presence of endotympanic fluid without any sign or symptom of acute ear infection, which may lead to hearing loss or long-term sequelae and have a negative impact on speech development and behaviour. Aim of the study was to determine the influence of adenoidectomy on middle ear function in children with chronic adenoiditis and to correlate degree of adenoid hypertrophy with middle ear function.

Methods: This cross-sectional study comprised 50 cases, who were 5-12 years of either sex presenting to ear, nose and throat outpatient department (ENT OPD) with grade 3, 4 adenoid hypertrophy. After detailed history and clinical examination, investigations such as pure tone audiogram, impedance audiometry, X-ray nasopharynx and diagnostic nasal endoscopy were carried out to confirm the diagnosis. All patients were posted for adenoidectomy by curettage. They were followed up at 1st, 3rd and 6th month for pure tone audiometry and impedance was done at 6th month of surgery.  

Results: In this study, maximum number (82%) of cases belonged to more than 7 years age group. On otoscopy, dull, amber coloured tympanic membranes ™ was the most common finding in 78% of cases. 66% had adenoid hypertrophy grade three and 34% had adenoid hypertrophy grade four. Mean audiometry findings at preoperative, and one month and 3 months post-op intervals are 24.2, 13.28 and 12.2, and the p value is less than 0.0001, which is statistically significant.

Conclusions: It may be concluded, that adenoidectomy completely eliminates the effusion in the middle ear cavity and exhibits significant postoperative hearing improvement.
