Anterior Segmental Osteotomy surgery affect on the nose?

An anterior maxillary osteotomy could have an aesthetic effect on the nose. For this reason rhinoplasty surgery should be delayed until 6 months after the maxillary osteotomy.

This is a great question, and not always a straightforward answer.  As a surgeon who performs both maxillofacial surgery and rhinoplasty I can tell you what I've learned from my experience. I assume you are having both jaws brought forward, correct?  The lower jaw will not affect the nose, but advancing the maxilla will.  Depending on where the surgeon makes the cut in the upper jaw, it will likely advance the tip of your nose forward as well, making it look projected.  Most people have some asymmetry to the jaw and the advancement is not perfectly equal on both sides (it may be tilted or shifted slightly to one side).  While you won't notice that your jaw is unequal, you may notice that your nose looks different. I would recommend getting a rhinoplasty AFTER the double jaw surgery.  Shifting the jaws will create a huge change in the face and you may want more or less changes to the nose after your jaws heal and you adjust to your new face structure. Best of luckDr Rodman
