    Summary

    This study details a patient with progressive right ear hearing loss due to auditory meatus erosion. Surgical intervention successfully preserved hearing function, maintaining 100% discrimination scores.

    Area of Science:

    • Neurosurgery
    • Audiology
    • Otolaryngology

    Background:

    • Acoustic neuromas can necessitate surgical resection, potentially leading to hearing loss.
    • Progressive erosion of the auditory meatus presents a significant challenge in hearing preservation.

    Observation:

    • A patient experienced five months of worsening right ear hearing loss.
    • Pre-existing deafness in the left ear resulted from prior acoustic neuroma surgery.
    • Polytomography revealed progressive erosion of the right auditory meatus.

    Findings:

    • Surgical resection of the acoustic neuroma was performed via right suboccipital craniotomy.
    • Post-operative audiological assessment indicated hearing preservation at a 30 dB level.
    • The patient maintained 100% speech discrimination scores following the procedure.

    Implications:

    • This case highlights the feasibility of hearing preservation in complex otological cases with auditory meatus erosion.
    • Successful surgical outcomes underscore the importance of advanced neurosurgical techniques in managing acoustic neuromas.
    • Effective audiological monitoring and surgical planning are crucial for optimizing hearing function post-treatment.
