Over 6 months after the replacement of Medpor RZ square extended chin implant (5mm projection) with the same, but slightly bigger model (7mm) I ended up having two soft lumps on the each side of my jawline, which makes my face look irregular and asymmetrical. But when I gently press the lumps with my fingers, then my jawline becomes 100% regular, so it's clear that the implant is correctly positioned but the soft tissue is a problem in my case. What is it and how can I get rid of it?
