    Summary

    This study introduces a novel surgical approach for acoustic neurinomas (vestibular schwannomas), aiming for improved tumor removal, hearing preservation, and reduced complications. The technique combines mastoidectomy with the suboccipital route for better outcomes.

    Area of Science:

    • Neurosurgery
    • Otolaryngology
    • Skull Base Surgery

    Background:

    • Acoustic neurinomas (vestibular schwannomas) are typically treated via middle fossa craniotomy, suboccipital, or translabyrinthine approaches.
    • Current methods have limitations in tumor removal, hearing preservation, and complication rates.

    Purpose of the Study:

    • To propose a modified surgical technique for acoustic neurinoma resection.
    • To enhance tumor removal efficacy.
    • To improve hearing preservation and minimize postoperative complications.

    Main Methods:

    • A combined approach involving mastoidectomy to expose the posterior fossa dura.
    • Obliteration of the mastoid with adipose tissue.
    • Subsequent use of the suboccipital route for tumor resection.

    Main Results:

    • The proposed technique facilitates dissection of the internal auditory meatus.
    • It reduces the risk of labyrinthine injury and subsequent hearing loss.
    • It aims to eliminate postoperative cerebrospinal fluid (CSF) otorhinorrhea.

    Conclusions:

    • This modified surgical approach offers potential advantages for acoustic neurinoma treatment.
    • It may lead to better functional outcomes and fewer complications compared to traditional methods.
