First of all, keep in mind that I am unable to diagnose you because I am unable to examine you, this forum is for educational purposes.
AcousticAcoustic neuroma
Acoustic trauma neuromas are a non-malignant tumor that arises from the 8th

Nerve conduction velocity (also called
vestibularAcoustic neuroma schwannomas). The most
commonCommon cold presentation of acoustic neuroma is decreased hearing on the side of the tumor. However 20% will also have vertigo (sensation of room spinning) and up to 70% will have a sense of imbalance. Many patients also have tinnitus (ringing in the ear). Larger tumors (from 1.5 cm to 3cm) can also cause facial weakness/numbness, hemi-facial spasms and pain). Acoustic neuromas are often treated conservatively (no surgery, repeat MRIs) until they are greater than 1.5 cm or the symptoms become unbearable. There are a number of risks associated with the procedure (which you should discuss with your surgeon) including permanent hearing loss, loss of balance/vertigo, CSF leaks, and chronic recurrent headaches. Many patients will require vestibular rehab after surgery. There is also Gamma-knife radiation for poor surgical candidates, but if surgery is required after gamma-knife then the rate of complications are even higher. Thus the decision to have surgery or to wait is a complex one, and with a small acoutic neuroma (1cm) the risks of surgery may outweight the potential benefits. I would suggest that you go to a major academic center and meet with a neuro-otologist (neurologist that did a fellowship in ear/balance/vertigo issues) for a second opinion.
I hope this has been helpful.
