While dizziness and nausea may occur for a day or two following general anesthesia, you obviously are having symptoms that are NOT related to a side effect of anesthesia as they have persisted for years. "Telangectasia" refers to widening of small groups of vessels or cappillaries. The "vestibular" nerve or 8th cranial nerve (as well as several other nerves) has its nuclei (or the origin of the nerve) in the Pons. The 8th cranial nerve (The Vestibular Nerve) is involved with hearing and balance. Syndromes due to anatomic abnormalities within the Pons may result in several different "syndromes" and many different symptoms.
These include:
1. Loss of pain and temerature sensation
2. Loss of sensation in the face
3. Hiccups
4. Miosis (small pupil) and Ptosis (drooping of the eyelid)
5. Dizziness
6. Loss of balance
7. Nausea
8. Gait (walking) disturbance.
I understand your vestibular testing came back as normal. If you came to my office with the history your describe, I would send you to see a NeuroSurgeon to explore options for treatment of the telangectasia. To answer your question simply "Yes" it is quite possible the telangectasia is causing your symptoms.
Another thought worth mentioning here is a disorder known as Meniere's Syndrome or Meniere's Disease. Meniere's (pronounced "men-ears") Disease is a problem involving the inner ear. It is caused by fluid in the canals of the inner ear. Although it can be a troublesome condition, Meniere's is not a serious condition and is not contagious. People with Meniere's don't usually have symptoms all the time. When symptoms occur it is called and "attack." It usually affects only one ear but can affect both ears in about 30% of patients. The symptoms present during an attack include dizziness, a feeling of fullness or loss of hearing in the ear, and tinnitus (ringing in the ears).
The doctor examining the patient with possible Meniere's Disease will closely examine the ears and check for problems with balance.
Treatments for this condition include limiting dietary salt (less salt will likely help reduce the potential for fluid to build up in the canals of the inner ear), also a medicine called a diuretic (water pill) may be prescribed as the best treatment for this condition remains medication which helps reduce the potential for fluid to collect in the inner ear. During episodes of dizziness, a medication called "Antivert" may be prescribed. Additionally, for the nausea which commonly accompanies the "attacks", medicine may be helpful.
I hope this is helpful to you. I wish you well and please don't hesitate to contact me if you have further questions.
