    A new sweep-frequency tympanometer precisely diagnoses auditory ossicular lesions by analyzing middle ear acoustic features. This advanced device accurately identifies ossicular dislocation and fixation, improving diagnostic capabilities for middle ear conditions.

    Area of Science:

    • Otolaryngology
    • Biomedical Engineering
    • Acoustics

    Context:

    • Auditory ossicular lesions require precise diagnostic tools.
    • Existing methods may lack specificity in differentiating ossicular conditions.
    • Middle ear acoustic impedance measurements are crucial for diagnosis.

    Purpose:

    • To develop and validate a sweep-frequency tympanometer for precise diagnosis of auditory ossicular lesions.
    • To establish normal diagnostic ranges for key acoustic parameters.
    • To evaluate the device's accuracy in identifying ossicular dislocation and fixation.

    Summary:

    • A sweep-frequency tympanometer continuously sweeps probe tone frequency (200-2,500 Hz) to measure acoustic middle ear features.
    • Measurements of acoustic pressure and phase at -200 and 0 dapa are analyzed, with key parameters (BHz, BdB, ZHz, PHz, Pdeg) digitally displayed.

  • Normal ranges were established from 200 ears, and the device correctly diagnosed 8/8 ossicular dislocations and 12/14 ossicular fixations.

    • Impact:

    • Provides a more precise diagnostic tool for auditory ossicular lesions.
    • Enhances the ability to differentiate between ossicular dislocation and fixation.
    • Contributes to improved clinical management of middle ear pathologies.
