OBJECTIVE: The use of autologous fat as a soft tissue filler has increased over the past decade in both reconstructive and aesthetic surgeries. Enhancement of autologous fat grafts with the addition of the stromal vascular fraction (SVF) has been reported to improve long-term volume retention. Stromal vascular fraction is most commonly isolated using enzymatic digestion, but it is unknown what effect the digestion process has on the adipocytes and SVF cells that comprise the graft. Some clinicians have reported use of enzymatically digested fat grafts to alter the physical properties of the tissue in specialized applications...

Bony reconstruction of the mandible after surgical resection results in improved rehabilitation and aesthetics. Composite tissue transfer has transformed reconstruction, particularly in patients who have received radiotherapy. However, there is morbidity related to free tissue transfer. Free nonvascularized bone grafts have much lower morbidity. Surgeons believe that free bone grafts greater than 6.0 cm are prone to failure. The aims of this study was to assess whether bone grafts greater than 6.0 cm in length have a high risk of failure...

Craniomaxillofacial reconstructive surgery is a challenging field. First it aims to restore primary functions and second to preserve craniofacial anatomical features like symmetry and harmony. Three-dimensional (3D) printed biomodels have been widely adopted in medical fields by providing tactile feedback and a superior appreciation of visuospatial relationship between anatomical structures. Craniomaxillofacial reconstructive surgery was one of the first areas to implement 3D printing technology in their practice...

A better understanding of factors that can lead to papilla formation or recession, such as the type of site where the implant was placed, is of fundamental importance to the aesthetic success of the rehabilitation. The aim of this study was to perform a systematic review of the literature regarding the formation or recession of papilla adjacent to implants placed in fresh, healing or healed sites. The protocol for this study was registered in the PROSPERO database (registration number CRD 42016033784). An electronic search was performed by two independent reviewers who applied the inclusion and exclusion criteria on the PubMed/MEDLINE, Scopus, and Embase databases from January 2005 up to February 2016...

Mid-face augmentation via a Le Fort I osteotomy is a commonly performed operation. Advancement of the upper jaw and associated structures (nose, lower cheek areas) can certainly improve function as well as facial aesthetics and harmony. Often, in patients with severe mid-face deficiency, hypoplasia of the maxilla extends all the way up to the infraorbital rims. The receding infraorbital rim contributes to the negative vector of the globes. In patients with this level of mid-face hypoplasia, while advancing the maxilla at the Le Fort I level satisfies all of the requirements for orthognathic surgery, the deficient infraorbital rim remains unchanged and can actually accentuate the negative vector of the globes...

Gender dysphoria is estimated to occur in approximately 25 million people worldwide, and can have severe psychosocial sequelae. Medical and surgical gender transition can substantially improve quality-of-life outcomes for individuals with gender dysphoria. Individuals seeking to undergo female-to-male (FtM) transition have various surgical options available for gender confirmation, including facial and chest masculinization, body contouring, and genital surgery. The World Professional Association for Transgender Health guidelines should be met before the patient undergoes surgery, to ensure that gender-confirming surgery is appropriate and indicated...

BACKGROUND: Zygoma fracture is of clinical importance because malar prominence plays an essential role in facial appearance. Traditionally, most maxillofacial surgeons perform osteosynthesis with titanium plates and screws for rigid fixation. However, this procedure has certain disadvantages that include the possibility of implant exposure, palpability or loosening of the screws, painful irritation, temperature sensitization, and radiographic artifacts. In this study, we compared the function and satisfaction outcome between Bonamates(®) bioabsorbable implant and Leibinger titanium implant...

BACKGROUND: Augmentation or reconstruction of the calves is indicated in patients with thin legs, for bodybuilders, or when there is a defect after an injury or illness. The principle of placing implants under the investing crural fascia was worked out in the 1980s. The senior author (I.N.) introduced many technical modifications and improvements for this operation, among them the new instrument, an inserter for the calf implants. Presented patient material is unique in that the more challenging reconstructive cases almost equal the numbers of the aesthetic cases...

BACKGROUND: Screw retained implant prostheses seem to be an efficient restorative method to prevent peri-implantitis caused by cement excess around the abutment. The drawback of the screw-retained prostheses is the difficulty to realize an efficient access-hole filling functionally and aesthetically. Up to now, few in vitro and in vivo studies were reported in the literature. The aim of this study was to evaluate clinical performances of two direct filling materials through a period of 12 months...

BACKGROUND: Capsular contracture is a significant complication following aesthetic breast augmentation. Efforts to reduce this incidence have focused on the surgical approach, implant selection and IV antibiotics. Intra-operative methods to reduce the risk have had less investigation. This review focuses on these interventions and will document evidence to support pocket irrigation, nipple shields, drains and the use of an implant insertion funnel. METHODS: A comprehensive review of Pubmed, Scopus and Embase was performed to identify relevant papers published since 2000...

BACKGROUND AND OBJECTIVES: Oncoplastic reconstruction allows more patients to become candidates for breast-conserving surgery (BCS). Oncologic resection of a breast lesion is combined with plastic surgical techniques to improve aesthetic results. Choosing the best oncoplastic method is essential to optimize outcomes, improve cosmesis, and minimize postoperative complications. The aim of this study is to present a treatment algorithm incorporating oncoplastic techniques based on diagnosis, tumor size, tumor location, and breast size and shape...
