Is it possible to have a Lefort 1 procedure after a previous sliding genioplasty procedure?

I had a sliding genioplasty in 2019 but still have a slight oral incompetence. I've still been doing research trying to figure out my options. I've done myofunctional therapy and have not seen improvement. I have been told do have a excess vertical maxillary. I recently heard of the LeFort 1 procedure. Is it possible to have a a Lefort 1 procedure AFTER a pevious sliding genioplasty procedure?I
