Does slight upper jaw advancement in jaw surgery rotate the nose tip upward?

Question

I have an open bite, but I will also be getting my upper jaw (top row of teeth) moved forward to a small degree if I have surgery. My question is will this push my nose upward and increase the nasolabial angle? That's the only thing I fear because I do not want any change in my nose. Thank you.

Ricardo Mohammed-Ali, DDS, MBBS · Answer

It is important that you discuss this with your surgeon. Advancement of the maxilla could cause elevation of the nasal tip, widening of the alar base and changes to the nasolabial angle. The maxillary movement as well as the thickness of your soft tissues and the appearance of your nose presently will also determine the extent of these changes.Speak to your surgeon about 3D planning and showing a simulation of the soft tissue changes with surgery. It is not 100 percent accurate but can give an idea of the changes.

The change in the nasal base will depend not only on the movement amount but the final direction, the type of thickness of your nasal tissues presently, and the measures the surgeon takes to Control the areA at the surgery. Talk to your surgeon and discuss your concerns.
