Summary
This study establishes normative wideband tympanometry (WBT) values for the Turkish population. Findings reveal significant differences in resonance frequency and absorbance in infants, aiding WBT clinical application.
Area of Science:
- Audiology
- Otolaryngology
- Medical Physics
Background:
- Wideband tympanometry (WBT) is increasingly used for middle ear evaluations.
- Existing normative data for WBT is insufficient, particularly across diverse populations.
- Establishing age-specific normative values is crucial for accurate WBT interpretation.
Purpose of the Study:
- To determine normative wideband tympanometry values in the Turkish population.
- To analyze WBT parameters across different age groups.
- To provide a foundation for the widespread clinical adoption of WBT.
Main Methods:
- 150 volunteers were categorized into five age groups.
- Wideband tympanometry was used to measure resonance frequency (RF) and absorbance.
- Measurements were standardized at 0 daPa with a 90 dB SPL sound stimulus.
Main Results:
- Resonance frequency (RF) was significantly lower in infants aged 0-1 month.
- Absorbance at 250 Hz was significantly higher in infants (0-1 month) and young children (1 month-2 years).
Conclusions:
- The study provides essential normative WBT data for the Turkish population.
- Identified age-related differences in RF and absorbance are clinically relevant.
- These normative values are expected to enhance the diagnostic utility and clinical application of WBT.
