Summary
Radiosurgery effectively controls facial schwannomas, with 100% tumor control and improved facial nerve function in most patients. This treatment is recommended as the primary option for facial nerve tumors.
Area of Science:
- Neurosurgery
- Radiation Oncology
- Oncology
Background:
- Facial schwannomas are rare tumors affecting the facial nerve.
- Treatment options historically included surgical resection, often leading to functional deficits.
- Evaluating less invasive treatment modalities is crucial for improving patient outcomes.
Observation:
- 14 patients with facial schwannoma underwent radiosurgery.
- The mean follow-up period was 31.4 months.
- Tumor volumes ranged from 0.98 to 20.8 cm³; mean tumor volume was 5.5 cm³.
Findings:
- Radiosurgery achieved 100% tumor control, with 57% showing tumor shrinkage.
- No tumors progressed, and no further surgery was needed.
- Facial nerve function improved in 5 patients, remained stable in 8, and worsened in 1. Hearing function was unaffected. One patient experienced temporary facial palsy post-treatment.
Implications:
- Radiosurgery offers a highly effective and safe treatment for facial schwannoma.
- It provides excellent tumor control while preserving or improving facial nerve function.
- Radiosurgery is proposed as the preferred first-line treatment for facial schwannomas.
