Trial Summary

What is the purpose of this trial?

The purpose of this research is to collect data on the short and long-term effects of facial fat grafting by injectable tissue replacement and regeneration in the midfacial zone, with the use of the VialityTM system. The Viality system is a US Food and Drug Administration (FDA) cleared device.

Do I have to stop taking my current medications for the trial?

The protocol does not specify if you need to stop taking your current medications, but you cannot participate if you are taking anticoagulants.

What data supports the idea that Fat Grafting for Facial Rejuvenation is an effective treatment?

The available research shows that Fat Grafting for Facial Rejuvenation can be effective when done properly. One study highlights that understanding facial anatomy and personalizing the treatment are crucial for success. Another study suggests that using a careful technique to harvest and inject fat can lead to better results, as it helps the fat survive and integrate into the face. Additionally, a study on patients with facial fat loss due to HIV treatment found that fat grafting improved their appearance, with most patients being satisfied after two years. These findings suggest that Fat Grafting can be a reliable option for facial rejuvenation when performed with the right methods. ^{1 2 3 4 5}

What safety data is available for fat grafting for facial rejuvenation?

The research provided does not directly address the safety of fat grafting for facial rejuvenation using the Viality System or similar methods. However, it does mention the use of autologous fat injection for facial atrophy, which is a related procedure. In this context, the technique involves atraumatic procurement and careful injection of fat, with satisfactory results reported over a two-year period. No specific safety data for the Viality System is mentioned in the provided research. ^{4 6 7 8 9}

Is Viality a promising treatment for facial rejuvenation?

Yes, Viality is a promising treatment for facial rejuvenation because it offers an efficient way to process fat for grafting, which can help restore facial volume and improve appearance. ^{3 5 6 10 11}

Findings from Research

Fat grafting is a widely used method for facial rejuvenation, but its success depends on careful evaluation and treatment of both donor and recipient areas.

A thorough understanding of facial anatomy and personalized treatment approaches are crucial for achieving optimal results in fat grafting procedures.

Fat Grafting for Facial Rejuvenation in Asians. Yang, Z., Li, M., Jin, S., et al.[2022]

Standardizing fat grafting techniques for facial rejuvenation can significantly improve clinical outcomes, as variability in methods can lead to less optimal results.

Using low negative pressure for fat harvesting, proper centrifugation for processing, and careful injection techniques can enhance graft survival and effectiveness, leading to more predictable and long-lasting results.

A study of 17 female patients (average age 61) showed that combining autologous fat grafting with CO2 laser resurfacing significantly improved the appearance of fine wrinkles, deep folds, and pigmentation in the lower face, with p-values indicating strong statistical significance.

No complications were reported from the procedure, although one patient experienced resorption of the fat graft, suggesting that the treatment is generally safe and effective for facial rejuvenation.

Lipoinjection of autologous fat is an effective method to correct facial fat atrophy in HIV-positive patients using protease inhibitors, with satisfactory results observed over a 2-year period.

In about 30% of cases, patients required a reinjection of fat within the first few months after the initial procedure, indicating the need for potential follow-up treatments.

The study discusses a method for facial rejuvenation that involves using autogenous fat micrografts, which are harvested through a gentle syringe lipoaspiration technique, to restore lost volume due to aging.

Successful outcomes depend on careful handling of the fat micrografts to ensure proper vascularization and integration into the facial tissue, highlighting the importance of an atraumatic approach in the procedure.

The author has extensive experience (18 years) using fat transfer techniques, including pearl fat grafts and fat injections, for facial augmentation.

Pearl fat grafts are specifically used for delicate areas like eyelids and small depressions, while fat injections can enhance larger facial features such as the chin, cheekbones, and lips.

A survey of 75 physicians treating 17,376 patients revealed that injection lipolysis has an excellent safety record, with no deaths or serious complications reported, such as infections or skin loss.

While most patients experienced positive outcomes, 12.34% expressed disappointment with their aesthetic results, highlighting the importance of educating patients about realistic expectations before treatment.

In a study of 145 patients over an average of 50 months, facial infiltrations with polyacrylamide hydrogel (Aquamid) showed a low incidence of severe complications, with only one patient experiencing a local infection, indicating long-term safety for treating facial lipoatrophy.

Patient satisfaction was high, with 88.9% reporting they were satisfied or very satisfied with the results, particularly those with mild to moderate lipoatrophy, suggesting that Aquamid is an effective option for facial lipoatrophy repair.

The lipodissolution procedure using phosphatidylcholine solubilized with deoxycholate (PC/DC) was found to cause significant damage to subcutaneous tissue, including cell membrane lysis and reduced cell viability, in both rats and a human volunteer.

Histological analysis revealed that PC/DC treatment led to serious complications such as tissue fibrosis, fat necrosis, and vessel necrosis, raising concerns about the long-term safety of this cosmetic fat treatment.

The novel Poloxamer Wash, Absorption, mesh filtration System (PWAS) resulted in a higher adipose volume fraction (89% ± 3%) compared to the Ringer's Lactate wash, Decant, and mesh filtration System (RLDS) (76% ± 10%), indicating better quality of processed lipoaspirate for fat grafting.

Both systems effectively removed oil and maintained similar cell viability and processing times, but the PWAS demonstrated superior efficiency in concentrating fat, making it a promising option for plastic surgeons.

The targeted fat-grafting technique for temporal hollowing augmentation was evaluated in a study of 96 patients, showing a high satisfaction rate of 91.7% and a significant improvement in appearance, with 74% of treated areas improving by more than 2 grades on the Hollowness Severity Rating Scale.

The technique demonstrated a fat graft survival rate of 65.7% and an overall augmentation rate of 91.4%, indicating both safety and efficacy in restoring volume to facial areas with low complication rates.
