Are There Any Facial Muscles Problems That Can Occur From Cheek Implant Surgery?
Q: Dear Dr. Eppley, I recently read, that a revision on a chin implant that has been inserted through an intraoral incision, can lead to distortion of the chin muscle because this muscle would be cut through twice. I don´t have a chin implant, but porex cheek implants (inserted through an intraoral incision) that need to be shaved down on the left side. Now I would like to know if an intraoral performed cheek implant surgery also involves cutting through a muscle what eventually could lead to distortion of the soft tissue if this muscle is cut through twice.Thank you in advance for your reply!
A: When it comes to surgical access in the face for the placement of implants, they must be placed down at the bone level below the periosteum. This always requires cutting through attached muscle to get to the proper placement level. But there are significant differences between the lower jaw (mandible) and the rest of the face. The lower jaw is the only bone of the face that actually moves, the rest of the facial bones are fixed. This makes for significantly different types of muscular attachments.
The mentalis muscle of the lower jaw, while having no function in its opening and closing, covers the chin bone and affects the lower lip and soft tissue movements. When it becomes detached or scarred, one can develop lower lip and chin soft tissue sagging. While good soft tissue closure will avoid this problem it is always a risk. While there is nothing wrong with secondary intraoral chin surgery, the upper attachments of the mentalis muscle are being severed and reattached twice. This does increase the potential for secondary mentalis muscle problems.
The intraoral placement of cheek implants does not cut through any muscles of jaw motion or those responsible for any soft tissue support. There are no risks, therefore, for muscle scarring that would affect any facial function or appearance. The muscle issues of intraoral chin implant surgery do not apply to intraoral cheek implant surgery.
