Permanent lip fillers contraindication for lip lift?

I have had pms silicone oil injected in my lips in 2006. and now I want a bullhorn liplift, but the cosmetic surgeon I went to for a consult told me it can’t be done because I have permanent fillers in my lips and it’s a contraindication for it. Is this always the case? And are there any other doctors who don’t mind performing a liplift when there are fillers in the lip. I also don’t have any compilations with the filler and they are also not migrated.
