Can I have a facial fat transfer or facelift done in the future If i've had a facial injury? (photo)

Five years ago, mymaxillofacial surgeon injected my right masseter muscle by needle of an anesthetic for temporary relief from bruxism pain. He hit an artery and gave me a very painful muscle hematoma which resulted in a cheek depression. I've been diagnosed with"tethering to the dermis". I've been to two plastic surgeons, two maxillofacial surgeons and a physical therapist to help break down scar tissue. It has not helped. Drs. are afraid needle insertion will worsen it.
