Effect of Pterygomasseteric sling shortening via mandibular angle resection on postoperative skeletal stability in skeletal class III malocclusions treated with mandibular setback surgery.

Although the horizontal change at Pogonion followed a similar posterior trend in the experimental group, the difference did not reach statistical significance ( p = 0.225), likely due to its anatomical distance from the pterygomasseteric sling insertion and the small sample size.
