Can I still have seroma in the chin 7 months after chin implant removal? (photo)

I got my small size 5,5mm extended ana. silicone chin implant removed via external incision 7months ago.Implant stayed in only 2days removed due to not liking at all. Since then one side of my chin feels like it has some kind of water baloon inside it feels semi liquid semi jelly tissue. The other side of my chin feels squashy too but way more solid no water balloon feeling. It makes my chin look uneven. How can i know its seroma? Doctors not sure. Can i get it asperated after all this time?
