Cheek implants add contour and volume to cheeks that lack definition due to a weak cheek structure or the loss of contour due to age. Cheek implants come in various sizes and shapes and are silicone implants or hydroxyapatite implants which integrate with natural bone tissue. They are inserted through small incisions made in the lower eyelids or the mouth and are placed in small pockets in the cheek tissue. If they are placed in conjunction with another procedure like a facelift or rhinoplasty, the implants are inserted through the incisions for those procedures.
