Typmpanometric Findings Pre and Post Adenoidectomy Amongst Children with Obstructive Adenoid Enlargement

Area of Science:

• Pediatric Otolaryngology
• Audiology
• Pediatric Health

Background:

• Obstructive adenoid enlargement is a frequent childhood condition.
• Adenoid hypertrophy contributes to otitis media with effusion (OME), a primary cause of reversible childhood hearing loss.
• Tympanometry is crucial for diagnosing OME.

Purpose of the Study:

• To assess tympanometry findings in children before and after adenoidectomy.
• To evaluate the impact of adenoidectomy on middle ear status in children with OME.

Main Methods:

• A prospective cohort study involving 95 children (190 ears) aged 2-9 years.
• Tympanometry was performed pre-operatively and six weeks post-operatively.
• Participants had failed medical treatment for OME for at least three months.

Main Results:

• Pre-adenoidectomy, tympanometry showed high prevalence of Type B (24.7%) and Type C (38.4%) results.
• Post-adenoidectomy, Type A tympanograms increased to 82.1%, while Type B and C decreased significantly to 11.1% and 9.5%, respectively.
• A notable reduction in abnormal tympanogram types (B and C) was observed after adenoidectomy.

Conclusions:

• Adenoidectomy is an effective treatment for children with adenoid enlargement and OME, as evidenced by improved tympanometry results.
• The procedure significantly reduces the prevalence of abnormal tympanograms, suggesting resolution of middle ear effusion and improved middle ear function.
