Facial physiotherapy after facelift?

Physical therapy after facelift should not impact the results of the facelift in anyway. I would be sure to discuss with your plastic surgeon to make sure that there are no other concerns. 

At 3 months, your body has deposited the necessary collagen in order to "hold" your surgical result in place.  facial massage should have very little impact on your result.  Adverse factors such as excessive sun exposure, smoking, and/or large swings in weight are more likely to make your face age faster than what you are describing. 

You should wait a total of six months before doing any such manipulation. Its probably OK at this point, but better safe than sorry.

Agree with other consultants that facial physiotherapy is unlikely to damage the results of your facelift because at 90d,  your wound healing is approaching completion.  As most facelift procedures don't depend exclusively on redraping and tightening skin, alone, the deeper repair work on the SMAS, which most of us do, will provide the results as well as resist any external deformative forces applied. Many surgeons actually recommend lymphatic drainage immediately post-op, which is a lighter variation of the treatments you are receiving.  

this far out you should be fine.  most of the healing occurs within the first month.  sometimes when necks are "too tight" I actually recommend stretching exercises.  shouldn't be a problem.

I'd wait. Just postpone the residual dental work if you can and let the face heal another three months. This sounds like an aggressive maneuver for such a new wound.All the best,Talmage Raine MD

3 months after a face lift, manipulation of any sort will not alter the results.   The areas do not feel normal yet and it may be uncomfortable for you to have the therapy, but it will not undo anything or alter the results.
