Vestibular schwannoma is a benign slow growth of the hearing nerve, and typically produces hearing loss slowly. Balance symptoms are usually mild.
Hearing tests and MRI are essential in the diagnosis and monitoring of vestibular schwannoma.
The decision on how to treat these slowly changing swellings is made by an expert in the field, and will depend on the size and rate of growth.
