I had a HT from another surgeon about 4 years ago. The numbness area has still not gone away after 4 years. I was told it would take 3 months to a year. Is there still hope for my nerves to reconnect on their own? If not, is this correctible by surgery or any other methods?
Thanks.
Numbness after a year reflects some nerve damage. I would want to know where you are numb. There are nerves in the back of the head than can be damaged from surgery. They are the greater and lesser occipital nerves, temporal and third occipital nerve. The following image shows the major nerve distribution and it may correspond to the area where your sensation is impacted:
As you can see from the picture, these nerves specifically cover different areas of the scalp. If any of these nerves are injured, a sensory defect will reflect the nerve’s distribution. We are fortunate that these nerves overlap in most people, and if one is damaged, the other has a distribution that covers the damaged nerve. It sounds like your back-up system did not work.
After 4 years, the nerves usually are dead, so that surgery (which is very difficult anyway) will not work. If there is pain in these nerves, then there are things that can be done to alleviate the pain, but usually after 4 years, all pain should have gone away.
