RESUMO

In recent years, 3D design and printing technology has been successfully used in maxillofacial bone reconstruction procedures. We had the opportunity to observe its benefits in the manufacture of custom facial implants. The production is so precise that perfect anatomical congruence and biocompatibility are possible. Within the plastic and maxillofacial surgery department of the University Hospital of Liège, we had the opportunity to perform two operations requiring facial skeleton redefinition implants. The purpose of this article is to highlight the current possibilities of facial prostheses via new 3D techno¬logies, but also the advantages and possible complications of this type of surgery.

RESUMO

OBJECTIVES: The primary goal of rhinoplasty is patient satisfaction and improved quality of life. The present study was conducted to assess patient satisfaction with face and nose appearance, and quality of life after rhinoplasty. METHODS: Patients presenting for rhinoplasty completed the FACE-Q survey. This is a new instrument that measures patient-reported outcomes in those undergoing aesthetic procedures. The FACE-Q scales include satisfaction with facial appearance overall, satisfaction with the nose, psychological well-being, psychosocial distress and social function. RESULTS: Sixty-five patients completed the FACE-Q at pre-operative and at post-operative follow-up visits. Post-operative scores increased significantly in terms of: satisfaction with facial appearance (p < 0.0001, t = 15.639, degrees of freedom = 64); social function (p < 0.0001, t = 12.208, degrees of freedom = 64); psychosocial distress (p < 0.0001, t = 13.864, degrees of freedom = 64); psychological function (p < 0.0001, t = 12.681, degrees of freedom = 64); and satisfaction with nose (p < 0.0001, t = 16.421, degrees of freedom = 64). Most patients reported more than 79 per cent satisfaction with the post-operative outcome. CONCLUSION: The FACE-Q is an adequate instrument for determining successful aesthetic surgery based on patient satisfaction.

RESUMO

Many of the aesthetic facial procedures can be performed simultaneously at the time of initial orthognathic surgery. Correction of any residual deformities after surgery, such as mandibular notching, malar asymmetry, labiomental crease, and any camouflage treatment, should be performed as a delayed procedure, when the outcome is more predictable. Additionally, these procedures could be used to enhance the orthodontic result, without the need of osteotomies to reposition the bones.

RESUMO

BACKGROUND: This study investigated the efficacy of extracorporeal shock wave (ESW) application in stimulating dermal thickness, vascularity, and collagen synthesis of facial skin in a large animal model. MATERIALS AND METHODS: The facial skin of the maxillary and mandibular areas of goats (n = 6 per group) was treated with ESWs of different intensities (0.15 and 0.45 mJ/mm2; 1000 pulses). After 4 d, histology and immunohistochemistry were used to evaluate the following: dermal thickness, total number and abundance of microvessels, amount of type 1 collagen, and α-smooth muscle actin expression. RESULTS: Dermal thickness, number and abundance of microvessels, and collagen synthesis increased after ESW application at both intensities (each P < 0.05). When comparing ESW groups, the highest collagen abundance was seen after 0.15 mJ/mm2 (P = 0.034), whereas the highest number of microvessels was detected after treatment with 0.45 mJ/mm2 (P = 0.002). CONCLUSIONS: A single-session application of focused low-energy ESWs to facial skin can increase dermal thickness by stimulating collagen production and local microcirculation. These findings commend the technique for future investigation for pretreatment of local or microvascular skin flaps to enhance tissue healing.

RESUMO

Fat grafting has evolved over the past two centuries and has revolutionized regenerative medicine, aesthetic and reconstructive surgery. Fat grafting provides a safe and minimally invasive technique to improve signs of aging, sun damage, and congenital and acquired craniofacial deformities. The Coleman technique for harvesting, processing, and grafting provides a reliable strategy for consistent results. However, unanswered questions remain regarding the biology of fat grafting, survival mechanisms, and regenerative properties. The future of fat grafting is bright and includes cell-based therapy and extracellular matrix-based scaffolds. This article provides an overview of the past, present, and future of facial fat grafting.

RESUMO

In Asia, young patients undergo pan-facial fat injection for facial contouring rather than rejuvenation. Although the procedure is widely performed, there is no singular approach that has been shown to have consistent results. The author's approach based on the facial fat compartment theory is presented here. The injection area is classified into functional zones and transition zones. A retrospective review was performed to evaluate the effectiveness of this approach. Satisfactory results were achieved in 96% of cases. In the author's view, this approach is safe, easy to learn, and produces satisfactory stable aesthetic results based on the facial fat compartments.

RESUMO

Craniofacial deformities represent a great challenge for the patient and the plastic surgeon. Fat grafting has allowed a shift in paradigm for craniofacial reconstruction by providing a less invasive and safer alternative than traditional reconstructive options. Increasing evidence supports its use with optimal results. This article examines the evidence and practical aspects involved in the decision making and technique of fat grafting to treat secondary craniofacial deformities.

RESUMO

Facial fat grafting is increasing worldwide. Although there are few reports in the literature on complications following facial lipofilling, rare but serious complications include embolic risk to local end organs such as the skin and eye, and the central nervous system. Treatment strategies are outlined. The key to prevention of complications is understanding the regional anatomy. It is imperative to adhere to the safe and efficacious techniques to minimize risk. Every surgeon who performs facial fat grafting should establish a systematic method to deliver safe, consistent, and long-term results for their patients.

RESUMO

The author provides his preferred approach to fat grafting for facial rejuvenation. The preferred donor sites include low abdomen and inner thigh. Fat grafts should be harvested with low negative pressure to ensure the integrity and viability of adipocytes. Fat grafts can be processed with proper centrifugation that can reliably produce purified fat with concentrated growth factors and adipose-derived stem cells, all of which are beneficial to improve graft survival. The approach described in this article is supported by the most scientific studies and thus may provide a more predictable long-lasting result if performed properly.

RESUMO

Injectable tissue replacement and regeneration (ITR2) is a standardized fat grafting technique, which anatomically addresses losses of facial volume, laxity, and sun damage of the skin resulting from the natural processes of aging. Based on the structural differences of fat existing in the deeper versus the superficial fat compartments of the face, while accounting for skeletal losses and skin aging, ITR2 utilizes 3 sizes of fat grafts-millifat (parcel size 2.0-2.5 mm), microfat (1.0 mm), and nanofat (<500 µm)-to replicate characteristics of fat cells lost with facial decay and provide increased blood supply and improvements in aging skin.

RESUMO

Fat grafting is one of the most prevalent fields in facial rejuvenation at present. The procedures include the evaluation of recipient and donor areas, as well as fat harvesting, processing, and reinjection. Inappropriate treatment of each link may affect the final effect on the whole. The authors believe that understanding of facial anatomy and personalized therapy are the key to successful operation.

RESUMO

Reversing structural changes in aging skin gained potential after the therapeutic use of adipose-derived stem cells was described. Nanofat is a highly concentrated solution of progenitor cells without viable adipocytes. Nanofat grafting creates striking skin quality improvement. The availability of adipose-tissue combined with straightforward mechanical protocol to process fat brings regenerative and antiaging medicine into real-life clinical practice. Association with other cofactors (hyaluronic acid, botulin toxin, and vitamin C) and therapies (microneedling and drug delivery) provides better outcomes. This article describes the techniques and the authors' experiences in nanofat grafting, and its potential new applications in regenerative medicine.

RESUMO

Fat grafting to the face for volume augmentation, and skin rejuvenation have become a popular procedure. However, the main obstacles to fat grafting include the unpredictable volume maintenance rate and the unpredictable number of treatments needed to obtain a satisfactory rejuvenate effect. Therefore, many patients need repeat sessions. However, serial fat grafting with fresh fat imposes a burden on the patient not only because of the pain but also because of the downtime of harvesting. Therefore, if the fat can be cryopreserved, and used many times in 1 harvesting, those burdens can be reduced.

RESUMO

Facial fat grafting is a small-volume procedure and is primarily performed for facial rejuvenation, contouring, or regenerative surgery. The unsatisfying retention rate after fat grafting, however, led to unpredictable outcomes, subsequent multiple procedures, and even some complications. A variety of methods have been proposed to enhance the results of facial fat grafting, including several established surgical principles and many possible new techniques. Adding stem cells, fat preparations, and platelet concentrates may improve the survival after fat grafting but randomized controlled clinical studies are needed to determine their safety and efficacy as well as clinical indications for each technique.

RESUMO

This study used stromal vascular fraction gel (SVF-gel), a mechanically processed fat-derived product, to treat eye bag and tear trough deformity. SVF-gel is prepared by a process of centrifugation and intersyringe shifting and is particularly rich in SVF cells and native adipose extracellular matrix. SVF-gel injection is used alone or combined with transconjunctival eye bag removal. High satisfaction was noted among patients treated with SVF-gel injection for periorbital rejuvenation with fairly low complication rates. SVF-gel injection is a good alternative to assist transconjunctival lower eyelid blepharoplasty and correct the palpebromalar groove, tear trough deformity, and supraorbital hollow.

RESUMO

Autologous fat graft has limitations, especially long-term unpredictability of volume maintenance. The mechanical enrichment of fat graft with adipose-derived stem cells (ADSCs) could guarantee the survival of fat grafts. After decantation, washing, and centrifugation of lipoaspirate, the authors carried out histochemical analysis and flow cytometry to determine the best layers for preparing ADSC-enriched fat. After centrifugation, the stromal vascular fraction (SVF) was separated by mechanical dissociation and mixed with another layer of intact adipocytes, which was injected into patients. All patients showed volumetric improvement after a single lipotransfer section, without overcorrection. The method is safe, has low cost, and is easily reproducible.

RESUMO

Defects in the face area caused by trauma, accident, tumor or congenital defects are treated with special facial prostheses. Besides esthetics, the most common problem with these prostheses is the retention of prostheses. In the present article review, the methods used for the retention of prostheses from past to present were researched, and the advantages of adhesives and implants, which are the most commonly used current methods, were evaluated. Current techniques, new materials, treatment options, and implementation procedures are described. The success of maxillofacial prostheses in meeting the expectations of patients and dentist doctors is increasing day by day with the development of adhesive material science, the emergence of technical knowledge, and the development of implant technology. Increasing the retention provides both ease of use and acceptance by the patient. Therefore, the chosen method for retention has great importance in the long-term prognosis of the prosthesis.

RESUMO

A face transplant is as challenging a surgical procedure as any patient can undergo. In this introduction I present the medical aspects of this surgery, the profound ethical issues it raises, and optimal interventions that clinicians can pursue to help these patients and their loved ones. I then discuss how to help other kinds of patients and loved ones who confront similar stresses. I end by presenting a goal that author Sharrona Pearl puts forth after she studied many face transplant patients. The efforts she urges should maximize our capacity to see face transplant patients-and anyone-as they are, as opposed to how they look.
