Wouldn't an IVRO be a good alternative to a BSSO in this case? Then one could get IVRO + Chinwing simultaneously.
My problem with the Bad Homburger method is it looks like it would create a very slanted ramus angle, which I don't find aesthetic. Some slant is ideal, as that 90? box look is awful, but the slant would surely get worse depending on how much advancement is required.
And does anyone if it truly is necessary to wait a while year to get a chinwing after a BSSO? My understanding is that the chinwing does not have to be done using the entire lower jaw. It should be possible to simply make the standard BSSO cut, advance the mandible and rotate, whatever for the proper bite. Then behind that osteotomy perform the chinwing for jaw angles, mandibular plane, ramus length, and smoothen it all out with HA paste.
Am I dreaming here? I know a BSSO will provide a great aesthetic improvement to my profile, it's just I want to get the improvements to my frontal view ASAP too. Put the whole thing behind me, you know?
