    Summary

    This study presents a modified singular neurectomy technique using a hypotympanotomy approach, reducing complications for benign paroxysmal positional vertigo (BPPV) patients. The method offers a safer alternative to vestibular neurectomy.

    Area of Science:

    • Otolaryngology
    • Neurosurgery
    • Vestibular Disorders

    Background:

    • Benign paroxysmal positional vertigo (BPPV) significantly impacts patient quality of life.
    • Traditional surgical interventions for intractable BPPV carry risks.
    • Singular neurectomy is an option for severe BPPV cases.

    Purpose of the Study:

    • To describe a modified surgical technique for singular neurectomy.
    • To evaluate the safety and efficacy of this modified technique.
    • To compare outcomes with existing surgical approaches.

    Main Methods:

    • A modified singular neurectomy utilizing a hypotympanotomy approach.
    • Delayed removal of the round window overhang to minimize trauma.
    • Case series analysis of eight patients undergoing the procedure.

    Main Results:

    • The modified technique demonstrated a lower complication rate compared to transmeatal series.
    • Successful treatment of severe BPPV was achieved in the studied cases.
    • The procedure avoids risks associated with intracranial surgery.

    Conclusions:

    • The modified singular neurectomy offers a safer and effective surgical option for intractable BPPV.
    • This technique minimizes the risk of cochlear damage and round window trauma.
    • It provides a less invasive alternative to vestibular neurectomy for select patients.
