Anyone familiar with Gamma Knife Therapy?

My mother had a gamma knife therapy done in December 2006 for an acoustic neuroma, and ever since Feb, she's been feeling really bad. She is always falling over while walking and can't maintain her balance. She hears these weird noises in her ear all the time, sounds like crickets or some other bug just buzzing away. and also when she looks at straight vertical lines, they vibrate right and left. and she always complains that she feels like her body is rocking or the surroundings are rocking, the same feeling u get when u step off a boat. Any idea wat she is suffering from? are these side effects of the gamma knife? or some other problem developing? will these problems go away? please advise!!!!

An acoustic neuroma is a Schwann cell鈥揹erived tumor of the 8th cranial nerve. Symptoms include unilateral hearing loss. Diagnosis is based on audiology and confirmed by MRI. Treatment is surgical removal.
Complications:
* Brain surgery results in complete removal of the tumor in greater than 95% of cases.
* About 95% of patients with small tumors will have no permanent facial paralysis following surgery. However, roughly two-thirds of patients with large tumors will have some permanent facial weakness following surgery.
* Approximately one half of patients with small tumors will retain useful hearing in the affected ear following surgery.
* There may be delayed radiation effects following radiosurgery, including nerve damage, loss of hearing, and facial paralysis.
Consult your doctor.
