Evaluating the Efficacy of Facial Scar Treatment Techniques Using Nanofat Grafting: A Case Series

Patient's psychological and aesthetic quality is affected by the appearance of scars since atrophic scars might be caused by infections or inflammations that resulted from preoperative procedures. Non-surgical methods have recently been developed to increase patient satisfaction and improve the appearance of scars. In our understanding, there has not been much published medical research assessing how well nanofat grafting techniques work in terms of treating facial scars. With a six-month follow-up after the intervention, this research intends to provide four cases where scars in the facial area were controlled utilizing these materials. Based on the cases shown, it can be seen that following the procedure, the scar's measurements were minimized, its color and texture improved, and there was no pain or itching. Given its safety and effectiveness, autologous nanofat grafting has become one of the most important and well-liked aesthetic procedures. It has been discussed how modifying injectable nanofat using fine needles has opened up new clinical applications for rejuvenating aesthetic medicine. Additionally, it was pointed out that injectable PRF has gained attention due to its high concentration of growth factors, which help to promote healing and improve the appearance of the skin. Furthermore, it can be efficiently shared with autogenous nanofat grafts, which support and enhance the efficacy of adipose-derived stem cells (ADSCs) and improve adipocyte blood circulation. The current use of modified nanofat in the treatment of facial scars is supported by the procedure's safety and low risk of injection-site problems. The consistent efficacy of modified-nanofat injection in the management of depression-related facial scars was validated by the outcomes of patient satisfaction surveys and physician evaluations.

Advancements in lip augmentation: A scoping review exploring novel techniques

Lip augmentation is among the most popular cosmetic procedures done today. Advancements in trustworthy techniques have made it feasible to alter the visual characteristics of the lips through the utilization of various injectable substances and surgical procedures. However, there is a lack of standardization in these techniques. The purpose of this review is to focus on novel dermal filler injection and surgical techniques for lip augmentation. We did a scoping review of the literature using PubMed, Embase, and the Google Scholar database to identify all original articles published up to June 2023, assessing new techniques that focus on lip augmentation. In our review, only two studies out of seven included studies were surgical whereas the other five studies were non-surgical. This suggests that injection of dermal fillers is currently the most opted technique performed. This review suggests that incorporating perioral rejuvenation into the plan for lower facial surgery can help to complete the youthful look sought by patients. Injectable fillers provide excellent but short-term benefits and additional options such as Modified upper lip lift and French kiss techniques exist that offer the patient permanent improvements at a low cost.

The Application of Blood Products in Plastic Surgery: A Systematic Review

Background

Due to their minimal trauma and relative safety, blood products are becoming increasingly popular in medical aesthetics. In recent years, research on the application of blood products has also been increased. This article will summarize the research progress of emerging blood products in plastic surgery in recent years.

Methods

We searched the PubMed database for literature related to the application of blood preparation in plastic surgery over the past 5 years and summarized them.

Results

Commonly used in plastic surgery are platelet-rich plasma, platelet-rich fibrin, concentrated growth factor, platelet-poor plasma, and mesenchymal stem cells derived from blood products. They can be used for wound repair and skin and autologous fat transplantation, and can be combined with laser therapy and facial rejuvenation.

Conclusions

Understanding the application pathways of blood products in plastic surgery and their respective advantages and disadvantages can help us better choose and use them.

Ten years of injectable platelet-rich fibrin

The use of platelet-rich fibrin (PRF) has seen widespread advantages over platelet-rich plasma (PRP) in many fields of medicine. However, until 2014, PRF remained clinically available only in its solid clotted form. Modifications to centrifugation protocols and tube technology have led to the development of a liquid injectable version of PRF (i-PRF). This narrative review takes a look back at the technological developments made throughout the past decade and further elaborates on their future clinical applications. Topics covered include improvements in isolation techniques and protocols, ways to further concentrate i-PRF, and the clinical impact and relevance of cooling i-PRF. Next, various uses of i-PRF are discussed, including its use in regenerative periodontology, implantology, endodontics, temporomandibular joint injections, and orthodontic tooth movement. Furthermore, various indications in medicine are also covered, including its use in sports injuries and osteoarthritis of various joints, treatment of diabetic ulcers/wound care, and facial esthetics and hair regrowth. Finally, future applications are discussed, mainly its use as a drug delivery vehicle for small biomolecules, such as growth factors, antibiotics, exosomes, and other medications that may benefit from the controlled and gradual release of biomolecules over time.

Tissue engineering strategies for breast reconstruction: a literature review of current advances and future directions

Background and Objective

Mastectomy is a primary treatment for breast cancer patients, and both autologous and implant-based reconstructive techniques have shown excellent results. In recent years, advancements in bioengineering have led to a proliferation of innovative approaches to breast reconstruction. This article comprehensively explores the promising perspectives offered by bioengineering and tissue engineering in the field of breast reconstruction.

Methods

A literature review was conducted between April and June 2023 on PubMed and Google Scholar Databases. All English and French articles related to bioengineering applied to the field of breast reconstruction were included. We used the Evidence-Based Veterinary Medicine Association (EBVM) Toolkit 14 checklist for narrative reviews as a quality assurance measure and the Scale for the Assessment of Narrative Review Articles (SANRA) tool to self-assess our methodology.

Key Content and Findings

Over 130 references related to breast bioengineering were included. The analysis revealed four key applications: enhancing the quality of the skin envelope, improving the viability of fat grafting, creating breast shape and volume via bio-printing, and optimizing nipple reconstruction through engineering techniques. The primary identified approaches revolved around establishing structural support and enhancing cellular viability. Structural techniques predominantly involved the implementation of 3D printed, decellularized, or biocompatible material scaffolds. Meanwhile, promoting cellular content trophicity primarily focused on harnessing the regenerative potential of adipose-derived stem cells (ADSCs) and increasing the tissue's survivability and cell trophicity.

Conclusions

Tissue and bioengineering hold immense promise in the field of breast reconstruction, offering a diverse array of approaches. By combining existing techniques with novel advancements, they have the potential to significantly enhance the therapeutic options available to plastic and reconstructive surgeons.
