Where is the Best Incision for Chin Implant: Through Mouth or Under Chin?

We do not perform chin augmentation with the mouth incision for two reasons, infection and migration. The implant tends to migrate upwards and outwards and has a much higher extrusion rate when placed through the mouth. It can also get infected more readily because of pooling saliva. It is better to make the incision underneath the chin area on the outside skin.

The internal or external approach for the insertion of the chin implant (augmentation mentoplasty) is basically determined by the preference of the surgeon. This preference is determined by the experience and results of each surgeon. Both approaches are acceptable. The most important factor is that the procedure be performed well by an experienced surgeon. In general, I tend to prefer placing the implant intraorally and I have many reasons for my preference. On the other hand, when I perform a facelift that necessitates making an external skin incision under the chin, I will place the implant through that external incision. As per example, if I perform a mentoplasty with a rhinoplasty, I will usually place the implant intraorally. If I perform a facelift, I will place the implant
externally through the skin.
