Wideband Tympanometry Findings in Otitis Media with Effusion-A Systematic Review

Area of Science:

• Pediatric Otolaryngology
• Audiology
• Diagnostic Imaging

Background:

• Otitis media with effusion (OME) is a common pediatric condition with potential for permanent hearing loss.
• Early and accurate diagnosis is crucial to prevent long-term complications.

Purpose of the Study:

• To evaluate the diagnostic utility of wideband tympanometry (WBT) for OME in children.
• To assess WBT's ability to differentiate between healthy and effusive middle ear conditions.

Main Methods:

• A systematic literature review was performed across PubMed, Scopus, and Embase (2000-2025).
• Data from 1115 ears with confirmed effusion and 721 healthy ears were analyzed.
• Absorbance patterns from WBT were compared between groups.

Main Results:

• Significant reductions in absorbance values were noted in low- and mid-frequency ranges for ears with effusion.
• WBT absorbance parameters effectively distinguished between healthy children and those with surgically confirmed middle ear effusion.
• Characteristic alterations in absorbance patterns indicate increased middle ear stiffness in OME.

Conclusions:

• Wideband tympanometry can identify specific middle ear mechanical system changes associated with effusion.
• WBT presents a promising novel audiological tool for OME diagnosis in pediatric populations.
• Further research is needed to confirm clinical utility and compare WBT with existing diagnostic methods.
