    Sound levels during ear surgery drilling can exceed 100 dBA, posing a risk of acoustic trauma. Surgical techniques and drilling device design should minimize noise exposure to protect patients.

    Area of Science:

    • Otolaryngology
    • Audiology
    • Surgical Technology

    Background:

    • Surgical drilling in the mastoid is a common otologic procedure.
    • High sound intensity levels generated during drilling may pose a risk of acoustic trauma to patients.
    • Quantifying noise exposure during these procedures is crucial for patient safety.

    Purpose of the Study:

    • To present a simple technique for measuring sound intensity during ear surgery.
    • To assess the sound levels produced by drilling in the mastoid.
    • To provide recommendations for minimizing acoustic trauma.

    Main Methods:

    • A straightforward measurement technique was employed.
    • Sound intensity levels were recorded during drilling in the mastoid of 6 patients.

    Main Results:

    • Sound levels during mastoid drilling in 6 patients exceeded 100 dBA.
    • The measured sound intensities indicate a significant potential for acoustic trauma.

    Conclusions:

    • Drilling devices should be engineered to prevent acoustic trauma.
    • Surgical techniques that minimize noise levels and exposure duration are recommended.
    • Further research into noise reduction strategies in otologic surgery is warranted.
