Plastic Surgery Case Study – Vertical Bony Chin Lengthening for Correcting An Upturned Soft Tissue Chin Pad

Background: The chin as a projecting facial structure has three dimensions. Of these dimensions horizontal projection is the most commonly seen and pursued by patients. Almost every chin implant is based on producing pure horizontal augmentation. The sliding bony genioplasty has fixation plates of various lengths that similarly are designed for increasing horizontal projection. A Read More…

Plastic Surgery Case Study – The Angular Geometry of Plate Fixation in Sliding Genioplasty Chin Augmentation

Background: The sliding genioplasty is an historic autologous chin augmentation procedure that has a long history. And while it is true that the down fractured bone is moved outward it really isn’t a sliding procedure anymore and hasn’t been for over almost 40 years. Originally the cut bone segment was slid forward along the osteotomy Read More…

Plastic Surgery Case Study – Secondary Chin Reshaping after Sliding Genioplasty Asymmetry

Background: The sliding genioplasty is one of the most well known of all the facial bone osteotomies. It is a unique lower facial osteotomy because it has no functional impact on jaw movement. The chin is a pure aesthetic aspect of the lower jaw that is not responsible for any biomechanical load transfer. It is Read More…

Technical Strategies – The Implant Overlay Concept for Increased Projection after a Sliding Genioplasty

Augmenting the chin with a sliding genioplasty is an autologous approach that has its distinct advantages. But when it comes to picking what the dimensional bony changes should be, particularly in the horizontal direction, it is not an exact science and is fraught with some of the same potential uncertainties as choosing the size of Read More…

Assessment of Bone Healing Across The Grafts Interpositional Gap in Vertical Lengthening Bony Genioplasties

When significant lengthening of the chin is needed the opening wedge bony genioplasty is the best procedure to do so. In this procedure the chin bone is cut with a horizontal osteotomy and down fractured. The desired vertical lengthening is then set by the application of a fixation plate c reating a bony gap between Read More…

Plastic Surgery Case Study – Vertical Lengthening of the Short Female Chin by Opening Wedge Osteotomy

Background: The vertical length of the female face extends from the frontal hairline (trichion ) down to the bottom of the chin. (pogonion) It is aesthetically divided in thirds which are ideally proportionate. From a surgical manipulation standpoint the facial thirds can be thought of as the forehead, nose-upper lip and chin as all of Read More…

Considerations in Secondary Sliding Genioplasties

The sliding genioplasty is the autologous form of aesthetic chin augmentation. Even though it is a bone procedure it is subject to the same aesthetic issues as any chin implant. Patients can have aesthetic postoperative concerns about the amount of forward projection/vertical length or width as well as asymmetry issues. And just because it is Read More…

Plastic Surgery Case Study – Triple Genioplasty for Improved Aesthetic and Functional Chin Results

Background: Chin augmentation is a general term that encompasses a variety of different techniques to do so. The two commonly used methods are an implant and an osteotomy. A wide variety of implant materials, styles and sizes are available to create almost every type of desired chin augmentation effect. For very significant chin augmentations beyond Read More…

Plastic Surgery Case Study – Reshaping the Short Wide face with Vertical Chin Lengthening and Anterior Cheek Augmentation

Background: In facial reshaping surgery a combination of diametric structural changes are needed to improve the facial balance. The most well known facial reshaping procedure is a reductive rhinoplasty and chin augmentation, a horizontal facial shape change that is best seen in profile. Vertical facial shape changes, however, are less appreciated and often underdiagnosed. As Read More…

Plastic Surgery Case Study – Large Vertical Chin Lengthening Osteotomy with Interpositional Grafts

Background: While the short chin is typically perceived as a horizontal deficiency, this is not the only dimension in which it can be seen to be inadequate. The one frequently overlooked chin deficiency is in the vertical dimension. The chin may have adequate forward projection and be in ideal position to the lips but can Read More…
