Neuroma after facelift: should I have plastic surgeon fix it or a neurosurgeon?

This is a very rare occurrence after a facelift. A neurosurgeon or a plastic surgeon could remove the neuroma, but a plastic surgeon may be more familiar with this area. Though removing the neuroma may remove the discomfort, it probably will not result in any return of ear sensation.

For peripheral nerves, a surgeon familiar with the typical anatomy is needed  Usually, that would be a Plastic Surgeon, who are also trained to deal with peripheral nerve surgery in most cases.  Good luck

In most cases further surgery is not necessary if numbness of the ear is your only complaint.  It may improve over the years.  If you are having a lot of pain in your neck, at the site where the nerve injury occurred, then sometimes surgery can be performed to reduce the pain (rather then to restore feeling to the ear) .  I would discuss this with your surgeon to get his/her opinion.
