When is stereotactic radiosurgery recommended for acoustic neuroma?

An acoustic neuroma, also called a vestibular schwannoma, develops near the nerves involved in hearing and balance. The team reviews MRI findings, tumour size and growth, hearing level, balance symptoms, facial nerve function, age and general health. Radiosurgery uses focused radiation to stop or slow further growth rather than remove the tumour immediately. It can be considered for a small or moderate-sized tumour, for documented growth, or when surgery would carry substantial concerns. Observation with repeat MRI or microsurgery may be more suitable in other situations.

Because the tumour lies close to important nerves and the brainstem, careful dose planning matters. Hearing may remain stable, change, or already be reduced; the team should discuss what outcome is realistic for the individual.

Gather previous MRI scans and hearing-test results, and describe changes in hearing, ringing, imbalance or facial movement. Ask whether the tumour has changed on serial imaging and how close it is to the brainstem or facial nerve. Discuss observation, surgery and radiosurgery together, including follow-up MRI, hearing checks and the possibility of delayed effects. Take medicines as instructed and report any implanted device or medical condition before planning.

Arrange prompt medical review for rapidly worsening balance, new facial weakness, sudden hearing change, severe headache, repeated vomiting or difficulty walking. Seek emergency help for sudden neurological symptoms, collapse, confusion or trouble swallowing. These signs need assessment because pressure on nearby structures or another urgent problem may require immediate care.

Has my tumour shown growth, and what does its location mean for treatment? How might each option affect hearing, balance and facial nerve function? How many follow-up scans and hearing assessments will I need? What symptoms should lead me to contact the team urgently?
