Observation and surgery offer similar outcomes for small acoustic neuromas, but observation may lead to growth requiring further treatment. Facial nerve outcomes in surgery improve with monitoring and a multidisciplinary approach.

Area of Science:

  • Neurosurgery
  • Otolaryngology
  • Radiation Oncology

Background:

  • Acoustic neuromas (vestibular schwannomas) management involves observation, surgery, or radiosurgery.
  • Surgical management, while conventional, can present controversies and challenges.
  • Evaluating treatment outcomes in a specialized referral setting is crucial.

Purpose of the Study:

  • To assess and compare the results of observation, surgery, and radiosurgery for acoustic neuromas.
  • To analyze treatment outcomes based on the initial intent to treat.
  • To evaluate the impact of tumor size and surgical techniques on outcomes.

Main Methods:

  • Retrospective analysis of 51 patients managed at a tertiary care acoustic neuroma referral center.
  • Patients were grouped according to their initial management intent: observation, surgery, or radiosurgery.

  • Facial nerve outcomes and tumor growth were key outcome measures.

    • Main Results:

    • 50% of observed tumors grew, necessitating surgery or radiotherapy.
    • Surgical facial nerve outcomes correlated with tumor size but improved with intraoperative monitoring and a multidisciplinary approach.
    • For small to medium tumors (<30 mm), observation and surgery (with monitoring) showed comparable results.

    Conclusions:

    • Observation is a viable option for small tumors, but carries a risk of growth.
    • Surgical outcomes for acoustic neuromas have significantly improved with advanced techniques.
    • Further prospective multicentric studies are needed to definitively assess management options.
