Hello.
Can you mention if the cerebellum was normal on MRI. Was an MRI done after the surgery ? Injury to cerebellar tissue can also present as imbalance, especially when the inner ear problem is ruled out.

Thank you for your response:) When he is sitting completely still the vertigo is almost non existent but as soon as he moves in any way, turning his head walking or riding in the car he gets extremely dizzy. He says it feel like a swirling in his head. Thanks again
Hello.
Since your husband is having the vertigo after the surgery, we can consider it to have originated during the surgery. The surgery procedure might have damaged certain nerve fibers concerned with balance.
A proper neurological examination at the neurologist's office will help a lot.
Roes he have the vertigo in the sitting and supine positions, too ?
