I'm sorry to read about your complications. It is highly
unlikely that you will have permanent nerve damage after the injections. Restylane
is a hyaluronic acid, which tends to attract water. This may lead to prolonged
swelling in the area of injection, and this tends to be more obvious in the
tear trough area because the area is so thin. It may take a few weeks for this
swelling to resolve. This may be the reason that you have prolonged numbness in
the area. Vitrase injections will help to dissolve the Restylane but may not
remove all of it. Good luck.
Upper lip numbness and/or impairment of upper lip motion are very unusual side effects from a tear trough injection; these side effects should be temporary. This is suggestive of inflammation of or pressure around the exit of the infraorbital nerve from the maxilla. I agree with the use of vitrase and steroids in this circumstance. Did you see a Facial Plastic Surgeon, Dermatologist or Plastic Surgeon to have the injection?
