Intraoral VS submental incision for genial implant? (Photos)

The incision for intraoral versus external approach in the placement of a chin implant depends on surgeon preference, which in turn, is based on training, experience, and the decision to combine chin augmentation with other procedures.  I prefer intraoral approach for chin augmentation, as I have had more experience with this in my training, it avoids an externally visible scar, and I believe it is less disruptive to the surrounding musculature.  That being said, I will often place an implant through an external approach when already using an under-the-chin incision for a neck lift or other neck surgery.   Infection risk is not significantly different between the two approaches.  In all, I do not think here is no "best" option for approach in chin augmentation.  Discuss your concerns with your surgeon, and best of luck with your procedure and recovery!

 Hi, I have performed many chin augmentations using chin implants over the past 30 years.  From the photos, your chin is quite weak and you do appear to be a good candidate for a chin implant surgery.  I always place the silastic chin implant through a small, curved incision under the chin...typically in less than 30 minutes often using local infiltration alone.  
 The intra-oral method is: far more invasive; has a greater degree of tissue dissection which means more swelling, bruising and recovery time; is a non sterile approach as the mouth in filled with bacteria unlike skin that can be prepped for surgery; requires cutting of the mentalis muscle attachment that can't be adequately re-attached...this means the implant can migrate upward after placement (I have seen this on numerous occasions when other surgeons used this approach and the patient subsequently came asking for replacement of the implant that had moved upward).  For all of these reasons, I use the submental approach and am confused why anyone would want a chin implant placed through the mouth.
 In case the argument has been made that somehow an intra oral approach is needed because the chin implant must be secured with metal screws, I strongly disagree with that argument.  I have placed chin implants in Military, SWAT, Law Enforcement Officers and various types of professional fighters that are extremely active without the need to secure the implant with metal screws or sutures.  I do ask facial implant patients to sleep on an airline type U-shaped pillow for one month after which time the periosteum has secured the implant from moving.
Hope this help.
