What Type of Surgery to Improve Jawline/Profile? (photo)

I would recommend getting properly worked up.  You may have functional airway issues that you are not aware of and it is possible that some of the jaw work might be considered medically necessary (depending on your converage).  A very good oral surgeon or an otolaryngologist who focuses on orthognathic surgery can help your with this.  They can also assess your overall facial aesthetics.  It may very well be that by increasing the projection of the jaw, your neck soft tissue and nose will be in better balance without undertaking rhinoplasty or neck liposuction.  This may be a much more satisfactory approach than having a chin implant.

A chin implant improves the chin profile by augmenting a weak retrusive chin.  This will bring the chin and mandible into alignment with the other facial features.  Any excess fat underneath in the neck can be removed with a neck lift.  The neck lift addresses both the fat above and below the platysmal muscle in the neck to recreate a jaw line by sculpting the neck.  The chin implant would give the most improvement if the patient had to choose only 1 procedure.

I would recommend a chin implant with sub mental liposuction and possible muscle tightening. Thi swill give you a dramatic change. Good luck.

The first thing to address if your orthognatic work.  You may benefit from a sliding genioplasty or chin implant, depending on what needs to be done to your teeth.  This would probably bring the biggest impact, followed by neck liposuction.

What would be the biggest impact?  First, you need to be assessed on your bite and general occlusion.  Sometimes special x-rays are performed to assess the relationship between the jaw( mandible) and the cheek bones ( maxilla).  This may require bony work.  A chin implant and or SAL may also be beneficial.
