Would like honest answer can sensory issues recover beyond 13 months post facelift? Is there any way to help this?

I am 12 months post-deep plane facelift, and though my face does not look stretched out, my skin feels numb under my chin, jaw, and in front of my ears. Yet I feel constant tightness and pulling sensations in my face, particularly around my mouth, when I speak. I feel as if there is a band around the bottom of my face pulling and choking me. Initially, it felt like things were healing, but then they started getting worse at around the 8-month mark, and I asked my plastic surgeon if it could be due to scar tissue forming. I saw a neurologist and had an MRI and a sonogram done to rule out any neurological issues. The conclusion is that what I am feeling is due to the facelift. At this point I am looking for an honest answer to the question, in a case such as mine, when sensory issues actually started worsening 7-8 months after the facelift, is recovery possible? I am guessing the buildup of scar tissue may be what causes it since the sensory issues ramped up so long after the surgery.
