Hearing preservation during acoustic neuroma removal is rare for tumors larger than 2.5 cm. While auditory brainstem response (ABR) monitoring is used, preserving wave V doesn't guarantee hearing, and losing wave V doesn't preclude it.

Area of Science:

  • Neurosurgery
  • Audiology
  • Neurology

Background:

  • Acoustic neuroma removal requires careful intraoperative monitoring to preserve neurological function.
  • Auditory brainstem monitoring provides objective measures of auditory pathway integrity during surgery.

Purpose of the Study:

  • To review the experience with far-field auditory brainstem monitoring during acoustic neuroma removal.
  • To identify factors influencing hearing preservation outcomes.

Main Methods:

  • Review of 144 consecutive acoustic neuroma removal cases since 1986.
  • Analysis of tumor size, preoperative auditory function, and auditory brainstem response (ABR) findings (specifically Wave V).

Main Results:

  • Hearing preservation is rare for tumors exceeding 2.5 cm.

  • Preservation or loss of Wave V on ABR did not reliably predict hearing preservation.
  • Preoperative presence of Wave I alone offered some hope for hearing preservation.

    • Conclusions:

    • Tumor size and preoperative auditory function are critical factors in hearing preservation.
    • Auditory brainstem response monitoring, particularly Wave V, has limitations in predicting postoperative hearing.
    • Postoperative hearing is typically stable or diminished compared to preoperative levels.
