Alternatively, uniformly solid implants that do not promote tissue growth may result in fibrotic encapsulation or migration of the implant [1]. For this reason, certain types of facial implants may be better suited based on procedure or anatomical site. Though complications associated with alloplastic implants are well documented, studies have shown dis- crepancy regarding the rate of complications associated with certain implants [5–8]. A comprehensive analysis of facial implant complication rates and how they affect aesthetic outcome is essential.

    507 Choosing the Best Procedure to Augment the Chin: Is Anything Better than an Implant? Jonathan M. Sykes, MD1 Rebecca Fitzgerald, MD2 1 Department of Otolaryngology/Facial Plastic Surgery, Address for correspondence Jonathan M. Sykes, MD, Department of University of California Davis Health System, Sacramento, California Otolaryngology/Facial Plastic Surgery, UC Davis Health System, 2 University of California Los Angeles, Los Angeles, California 2521 Stockton Blvd., #6206, Sacramento, CA 95817 (e-mail: [email protected]). Facial Plast Surg 2016;32:507–512. Abstract The chin plays a very important role in overall facial appearance, and aesthetic procedures to augment the chin in patients with microgenia can improve overall facial balance. Many procedures exist to enhance the appearance of a small chin. Procedures include surgeries such as placement of an alloplast implant and bony osteotomy of the mentum (sliding genioplasty). The advantages and disadvantages of each surgical technique are well documented. Although surgical augmentation of the chin has been the gold standard of therapy, recent development of injectable filler products with lifting capacity has changed the way that many practitioners alter chin shape and size. Filler agents allow augmentation of the chin in horizontal (projection), vertical, and Keywords transverse dimensions. Injectable fillers are a simple, noninvasive procedure that causes ► chin augmentation minimal to no downtime, incurs minimal risks, and allows the practitioner to shape the ► chin implant chin in three dimensions. This procedure allows patients to enhance their chin size ► genioplasty without requiring an operative visit. As more and varied filler products become FDA- ► volume approved, the versatility and application of these agents will increase.

  • Facial Augmentation with Implants
    Chapter 24 Facial Augmentation with Implants Farzin Sarkarat, Behnam Bohluli and Roozbeh Kahali Additional information is available at the end of the chapter http://dx.doi.org/10.5772/59188 1. Introduction The public’s demand for facial beauty has increased over time. Different cosmetic procedures have been introduced to meet this demand. The essentials of facial cosmetic surgery are: 1- Volume replacement and 2- Facial augmentation. Better aesthetic results have been achieved by using less invasive surgical techniques including lifting procedures, injectable fillers, autologous fat transfer, and facial implants. The malar eminence and chin are the most common facial sites augmented via implants. Autologous tissues have been the gold standard for facial augmentation for years; but today alloplastic materials are more commonly used. Drawbacks of autogenous grafting include: donor site morbidity, limited availability, limited moldability, and unpredictable resorption [1].An ideal alloplastic implant must be made out of a material that has low bioactivity or toxicity. It must also be stable and biocompatible [2]. An understanding of these qualities is needed to prevent complications or to treat them should they occur. 2. The aging process One of the primary advancements in cosmetic facial surgery has been the realization of volume loss in aging and volume replacement via cosmetic surgery [3-6]. The abundance of midfacial volume is one of the main reasons that makes a person look young, which means having the right amount of fat in the right areas of the face. The loss or shift of this fat is a main contributor to facial aging [7]. Loss of volume and volume shift occur in all regions of the face and neck and are the reasons for aged appearance [5, 6].The youthful midface has voluminous and © 2015 The Author(s).

Mandell, MD, MPH, Seattle, Washington from https://journals.lww.com/jtrauma ABSTRACT: Gender dysphoria, or the distress caused by the incongruence between a person’s assigned and experienced gender, can lead to significant psy- chosocial sequelae and increased risk of suicide (>40% of this population) and assault (>60% of this population). With an estimated 25 million transgender individuals worldwide and increased access to care for the transgender population, trauma surgeons are more likely to care for pa- tients who completed or are in the process of medical gender transition. As transgender health is rarely taught in medical education, knowledge of the unique health care needs and possible alterations in anatomy is critical to appropriately and optimally treat transgender trauma victims. Considerations of cross-gender hormones and alterations of the craniofacial, laryngeal, chest, and genital systems are offered in this review. by – BhDMf5ePHKav1zEoum1tQfN4a+kJLhEZgbsIHo4XMi0hCywCX1AWnYQp/IlQrHD3i3D0OdRyi7TvSFl4Cf3VC4/OAVpDDa8KKGKV0Ymy+78= Further research on the optimal treatment mechanisms for transgender patients is needed.

  • Facial Feminization Surgery Procedures Facial Feminization Surgery Procedures
    Facial Feminization Surgery Procedures Facial Feminization Surgery Procedures By Trinity Rose www.facialfeminizationsurgery.net Facial Feminization Surgery (FFS) refers to surgical procedures, which will alter a masculine face to a feminine shape through the use of plastic surgery, reconstructive surgery, and maxillofacial surgery. Procedures range from the use of soft tissue procedures, facial fillers, implants, to more invasive procedures involving the buring (grinding) of facial bones, and the cutting (osteotomy) of facial bones. Due to the fact people differ in facial characteristics; a combination of serval procedures may need to be used to alter the face to the desired result to feminize the face. Most people refer to Facial Feminization Surgery as FFS when describing it. There are a number of surgical procedures that can be used to feminize the face when it comes to FFS. Depending on your facial structure and degree of masculine features, one or many of the following procedures can be used to feminize the transsexual face: Forehead contouring: Complated by a high speed bur Forehead reconstruction: Complated by cutting out a section or sections of the frontal skull Forehead compression/controlled facture: Research in progress Jaw tapering: Completed by a high speed bur or a bone saw Chin contouring/Mentoplasty: Completed by a high speed bur and or chin inplant Sliding genioplasty: Completed by cutting and removing the chin Cheekbone augmentation Through the use of implants Cheekbone reduction Complated by a high speed bur Lip contouring/Lip lift trachea shave blepharoplasty (Eyelid surgery to correct sagging or drooping of the eyelids) Rhinoplasty Facial Implants Facial Fillers Facelift FFS surgeon listings Further links about surgery can also be found at the bottom of this page.

It is important that you read this information carefully and completely. Please initial each page, indicating that you have read the page and sign the consent for surgery as proposed by your plastic surgeon. GENERAL INFORMATION. Facial implants are specially formed solid, biocompatible materials designed to enhance or augment the physical structure of your face. The precise type and size of implants best suited for you requires an evaluation of your goals, the features you wish to correct and your surgeon’s judgment. While any area of your face can be augmented with implants, the cheekbones, chin, lips, nose, and jaw are the most common sites for facial implants. Facial implants can bring balance and better proportion to the structural appearance of the face and they can help define the face by increasing projection and creating more distinct features. Facial implant surgery is best performed on people whose head and skull have reached physical maturity, which generally occurs in late adolescence.
