Hi Damien and Helen...
I've visited a number of neuro surgeons and ENT in the Toronto area. I saw Dr. Rutka and his associated Dr. Guha at Toronto Western/General through the University Health Network. I also saw Dr. Chen (Sunnybrook) and Dr. Izukawa (The Queensway) who often work together in the Mississauga/Toronto area. I also received telephone consults with Dr. Friedman at House in L.A. and flew to BC to consult with a team out there Dr. Akagami and Westerberg.
Seeking treatment for AN can be very frustrating and time consuming, but well worth the time and effort invested. Be sure to take pen and paper with you to write down what the doctor tells you. There will be so much information that you will be glad you did. Take someone with you to ask questions that you will undoubtedly forget to ask. Do not be afraid to seek more opinions. Knowledge will give you the power to make your choice.
In regard to your facial symptoms, I've suffered numbness on the AN side for a long time, over a year, as well as decreased vision and visual disturbances I think are due to dryness in my left eye. I have very high word recognition but no balance response on that side. I did in the beginning suffer various facial twitches, nothing major, just eyelid twitching, and then my lip would twitch. My head used to have this kind of twitch thing too, but these symptoms have all faded over the year.
My sister in law suffered a different kind of brain issue called an AVM about 15 years ago. She had surgery but she now suffers from seizures and does have some very obvious, increasing facial twitches etc. It seems to me that when it comes to the brain, anything can really happen. This is the electronic center for all of our nerves...motor, sensory etc. I'm not surprised by symptoms anymore.
Good luck in your search. Perhaps you could try to attend the next ANAC Toronto Chapter meeting. It is on May 25th at 271 Spadina in Toronto. I am going to try to attend this meeting as I think it be my last prior to surgery.
