Summary

Stereotactic radiosurgery offers a safe and effective acoustic tumor treatment with a 97% tumor control rate. While not replacing surgery, it benefits select patients, preserving hearing in 38% at 1 year.

Area of Science:

  • Neurosurgery
  • Radiation Oncology

Background:

  • Acoustic tumors require effective treatment options.
  • Stereotactic radiosurgery presents an alternative to microsurgery for select patients.

Purpose of the Study:

  • To evaluate the efficacy and safety of stereotactic radiosurgery for acoustic tumors.
  • To assess outcomes including tumor control, hearing preservation, and neurological complications.

Main Methods:

  • Stereotactic radiosurgery performed under local anesthesia.
  • Data collection on patient discharge, functional recovery, tumor control, hearing preservation, and adverse events.

Main Results:

  • High tumor control rate (97%) with minimal tumor size reduction (23%).
  • Useful hearing preservation at 1 year was 38%.

  • Delayed onset of facial/trigeminal neuropathies (30%/33% at 1 year), mostly improving.

    • Conclusions:

    • Stereotactic radiosurgery is a safe and effective treatment for specific acoustic tumor patients.
    • It is a viable option for those with medical contraindications, bilateral tumors, or those refusing surgery.
    • It is unlikely to replace microsurgery but serves as a crucial alternative.
