My husband suffered significant damage to his facial nerve when his 3+cm AN was removed. At 9 months out there was no change and his surgeon suggested facial reanimation surgery. Ken wouldn't consider another surgery after a very difficult recovery from the first one.
Here on the boards, we read about Jackie Diels, the facial retraining therapist, based at the University of Wisconsin Medical Center and got in touch with her. She was able to detect the slightest indication that the facial nerve was healing and felt that Ken would benefit from facial retraining therapy. And he has!!! His face has improved tremendously. If you were to meet him, you might notice a slight asymmetry, but nothing that would indicate he had grade 4 facial paralysis after surgery.
If your nerve is intact, I urge you to get in touch with Jackie Diels in addition to exploring surgical reanimation options.
