    Summary

    Total ossicular replacement prosthesis (TORP) placement on the stapes footplate during middle ear surgery improved hearing. The anterior position of the TORP shaft yielded the greatest hearing gain in patients.

    Area of Science:

    • Otolaryngology
    • Neurosurgery
    • Biomedical Engineering

    Background:

    • Middle ear reconstructive surgery aims to restore hearing.
    • Ossicular prostheses, like the total ossicular replacement prosthesis (TORP), are used to reconnect the middle ear structures.
    • Optimal prosthesis placement is crucial for successful hearing outcomes.

    Purpose of the Study:

    • To evaluate the effect of TORP shaft position on hearing gain during middle ear reconstructive surgery.
    • To determine the optimal intra-operative placement of a TORP on the stapes footplate for maximum hearing improvement.

    Main Methods:

    • Intra-operative hearing was assessed in 10 patients undergoing middle ear reconstruction with TORP placement.
    • The TORP shaft was tested in three positions: anterior, central, and posterior to the stapes footplate.
    • Patients had radical mastoidectomy cavities and were operated under local anesthesia.

    Main Results:

    • The anterior position of the TORP shaft resulted in greater hearing improvement compared to the posterior position.
    • The central position provided an intermediate level of hearing gain.
    • Hearing gain varied based on the TORP's precise placement on the stapes footplate.

    Conclusions:

    • TORP placement position significantly impacts hearing outcomes in middle ear reconstructive surgery.
    • Anterior placement of the TORP shaft on the stapes footplate appears most beneficial for hearing restoration.
    • Intra-operative testing is valuable for optimizing TORP positioning during surgery.
