In our experience, most folks with acoustic neuroma never experience vertigo 
or unsteadiness until after surgical excision. Here's why (we think): The 
neuroma is very slow growing, so the CNS has ample time to compensate for 
changes in the output of the affected end organ. Surgery produces a sudden 
change in the output of the end organ (going from "some" to "none"), which the 
CNS will need time to compensate for. We routinely have our physical therapist 
who specializes in vestibular rehab see our acoustic patients 1 to 2 days 
after surgery to get them up walking, and to teach the patient a generic 
vestibular rehab excercise program.
