Background:

Triple jaw surgery, inclusive of a LeFort osteotomy, bilateral sagittal split osteotomy, and genioplasty, is used to maximize functional and esthetic outcomes for patients. This is achieved through the procedure’s measurable effects on the craniofacial skeleton but is also influenced by the soft tissue changes that occur as a result of the procedure. This study aims to characterize the three-dimensional (3D) soft tissue changes of triple jaw surgery.

Methods:

Patient demographics were collected along with pre and postoperative 3D images (3D VECTRA photosystem, Canfield, Fairfield, NJ). Orolabial anthropometric measurements were performed using Mirror (Canfield Scientific Inc., Fairfield, NJ).

Results:

Forty-eight 3D data sets were included. The male/female ratio was 0.6, with a mean age of 23.4 years. Significant postoperative decreases (P<0.001) were seen in the mean absolute distance from the lower lip to S-line and distance from lower lip to H-line. In female patients, upper vermilion fullness, lower lip height, lower vermilion fullness, distance from lower lip to S-line, and absolute distance from lower lip to H-line were found to fall within ideal norms postoperatively. In male patients, lower lip height, lower vermilion fullness, distance from lower lip to S-line, and absolute distance from lower lip to H-line were found to fall within ideal norms postoperatively.

Conclusions:

Triple jaw surgery has a significant soft tissue impact and can transform some orolabial measurements to conform to ideal norms.
