Facial Augmentation With Structural Fat Grafting

Evaluation of soft tissue profile changes following autogenous fat or onlay PEEK augmentation versus sliding genioplasty for correction of deficient chin: Randomized controlled clinical trial

AIM

The study was conducted to evaluate soft tissue profile changes using autogenous fat augmentation or onlay PEEK versus sliding genioplasty for correction of deficient chin in patients with retruded chin.

MATERIAL AND METHODS

Thirty-three patients with deficient chins were included in the study. The patients were distributed into 3 groups: the fat augmentation group as intervention I, the PEEK augmentation group as intervention II, and the osseous genioplasty group as control group. Preoperative and postoperative CBCT were performed for all patients. With the aid of MIMICS,3-MATIC, and PROPLAN software, diagnosis, virtual planning, and evaluation were performed. The Face-Q questionnaire was used to assess patient satisfaction.

RESULTS

There was a statistically significant difference regarding soft tissue relapse in the fat group after 6 months when compared to the control group (mean difference= 0.770), while there was no statistically significant difference regarding soft tissue relapse between PEEK and control group (mean difference= -0.060). Intragroup comparison has shown no statistically significant difference regarding soft tissue relapse within all groups between follow-up periods (P = 0.1389 for the fat group, P = 0.8739 for the peek group, and P = 0.8410 for the control group). All patients showed a statistically significant increase in scores of satisfaction with the chin between follow-up periods (P = 0.0165, P = 0.0150, and P = 0.0293) respectively.

CONCLUSIONS

Fat augmentation can be a good intervention choice in mild-moderate deficient cases. PEEK PSI has a stable surgical outcome.

Composite Microparticles of Fat Graft and GFR Matrigel Improved Volume Retention by Promoting Cell Migration and Vessel Regeneration

BACKGROUND

The retention volume of autologous fat grafts decreases after transplantation due to limited nutrition infiltration and insufficient blood supply. Structural fat grafts and the 3M (multipoint, multitunnel, and multilayer) injection technique have been considered to improve the survival of grafts; however, it is difficult for surgeons to practice in the clinic because grafts tend to gather into a cluster, especially in large volume fat grafting. Therefore, we hypothesize that prefabricated microparticle fat grafts (PFMG) may improve the retention rate.

METHODS

The C57BL/6 mouse fat particles were embedded in growth factor-reduced (GFR)-Matrigel to detect cell migration by immunofluorescence staining in vitro. PFMG was prepared by mixing mouse fat particles and GFR Matrigel in a 1:1 volume ratio and injected subcutaneously into C57BL/6 mice. Fat particles mixed with PBS in equal volume served as control group. The grafts were harvested at 1, 4, 8, and 12 weeks after sacrifice. The retention rate of grafts at each time point was measured, and the structural alterations were detected by SEM. Fat necrosis and blood vessel density were evaluated by histological analysis.

RESULTS

CD34+ cells are migrated from the PFMG and formed a tree-like tubular network in the in vitro study. The retention rate was higher in the PFMG group than in the control group at week 12 (38% vs. 30%, p < 0.05). After transplantation, the dissociated structure of fat particles was maintained in PFMG by SEM analysis. Histological analysis of PFMG confirmed less fat necrosis and more blood vessel density in the PFMG group at the early stage than in the control group. The GFR Matrigel was displaced by adipose tissue with time.

CONCLUSIONS

In this study, we developed a novel fat grafting method, PFMG that dispersed fat grafts and maintained the structure after transplantation. High volume retention volume of PFMG was achieved by promoting cell migration and vessel regeneration.

CD304 + adipose tissue-derived mesenchymal stem cell abundance in autologous fat grafts highly correlates with improvement of localized pain syndromes

ABSTRACT

Surgery, burns or surgery-free accident are leading causes of scars with altered tissue consistency, a reduced degree of motion and pain. Autologous fat grafting can dramatically improve tissue consistency and elasticity but less frequently results in the reduction of pain. Therefore, we analyzed different cell populations present within the adipose tissue to be engrafted and correlated them with the reduction of pain after surgery. Here, we identify a population of CD3 - CD4 - CD304 + cells present in grafted adipose tissue, whose abundance highly correlates with pain improvement shortly after surgery ( r2 = 0.7243****) as well as persistently over time (3 months later: r2 = 0.6277****, 1 year later: r2 = 0.5346***, and 4 years later: r2 = 0.5223***). These cells are characterized by the absence of the hematopoietic marker CD45, whereas they express CD90 and CD34, which characterize mesenchymal stem cells (MSCs); the concomitant presence of CD10 and CD73 in the plasma membrane supports a function of these cells in pain reduction. We deduce that the enrichment of this adipose tissue-derived MSC subset could enhance the therapeutic properties of adipose grafts and ameliorate localized pain syndromes.

The Evolving Function of Vasculature and Pro-angiogenic Therapy in Fat Grafting

Autologous fat grating is a widely-accepted method to correct soft tissue deficiency. Although fat transplantation shows excellent biocompatibility and simple applicability, the relatively low retention rate caused by fat necrosis is still a challenge. The vasculature is integral after fat grafting, serving multiple crucial functions. Rapid and effective angiogenesis within grafts is essential for supplying oxygen necessary for adipocytes' survival. It facilitates the influx of inflammatory cells to remove necrotic adipocytes and aids in the delivery of regenerative cells for adipose tissue regeneration in fat grafts. The vasculature also provides a niche for interaction between adipose progenitor cells and vascular progenitor cells, enhancing angiogenesis and adipogenesis in grafts. Various methods, such as enriching grafts with diverse pro-angiogenic cells or utilizing cell-free approaches, have been employed to enhance angiogenesis. Beige and dedifferentiated adipocytes in grafts could increase vessel density. This review aims to outline the function of vasculature in fat grafting and discuss different cell or cell-free approaches that can enhance angiogenesis following fat grafting.

The Versatile Role of Fat Injection During Various Genioplasties

BACKGROUND

Fat injection has become increasingly popular in aesthetic surgery, but there is a sparsity of literature regarding its role during genioplasty. In this study, we present the largest series of patients receiving fat injections to the chin for various indications.

METHODS

Data were collected from January 2016 to December 2021 for patients who underwent chin fat injection for a variety of chin refinements. Patients with chin fat injection were divided into isolated genioplasty with fat injection (CF), combined facial and chin fat injection (CFC) and combined chin fat injection and osseous genioplasty (CFG). Complication rates and reoperations were compared using Fischer's exact test between each cohort.

RESULTS

181 patients were included in final analysis, with 14 patients in CF cohort, 130 patients in CFC cohort, 24 patients in CFG cohort, and 13 patients who underwent genioplasty alone. Repeat fat injections were required in 17 (9.4%) patients overall, which included 14 patients (10.8%) of CFC subcohort and three patients (12.5%) of CFG subcohort (p > 0.05). No patients who underwent genioplasty alone or CF required reoperation. There were no significant differences in complications between genioplasty alone group (0%) in comparison to CF (7.1%; p = 1.00), CFC (6.2%; p = .53), or CFG cohorts (7.7%; p = 1.00).

CONCLUSION

Fat injection can safely correct minor chin deficiency or asymmetry, as either an isolated procedure or in combination with osteotomies. Additionally, fat injection enables advancement of the caudal segment to achieve superior outcomes by preventing unaesthetic deepening of labiomental groove which will not be advanced during sliding osteotomy.

Facial Fat Graft Injection Reduces Asymmetry and Improves Forehead Contour in Early Infancy Apert Syndrome Patients

BACKGROUND

The objective of this study is to report the outcomes of a modified comprehensive Apert syndrome surgical protocol in which fat injection was performed during early infancy concurrent with postposterior vault distraction osteogenesis (PVDO) distractor removal.

METHODS

A retrospective study was performed on 40 consecutive young patients with Apert syndrome who underwent PVDO and subsequent distractor removal between 2012 and 2022. Of these 40 patients, 12 patients underwent facial fat injection concurrent with distractor removal to treat residual supraorbital bar recession as part of a modified comprehensive Apert syndrome surgical protocol. Preoperative and postoperative severity of recession and irregularity was graded from 1 to 3, with 1 being less severe and 3 being the most severe. Recession severity was correlated with the number and type of suture fusion. The complication rate was stratified via a Clavien-Dindo scale.

RESULTS

The average patient age was 14.3±5 months, with 5 males (41.6%) and 7 females (48.3%). The average hospital stay was 1.08 days. The average volume of free fat graft injection was 8.29±5 mL. According to the Likert scale, forehead morphology improved in 91.67% of the patients. Complete resolution of supraorbital bar recession was achieved in seven patients (58.33%), all of whom presenting a single suture synostosis. One patient with a cloverleaf skull presented a type IIIB complication.

CONCLUSIONS

Facial fat grafting markedly reduces forehead asymmetry and improves forehead contour in Apert syndrome patients following PVDO. Total resolution of forehead recession directly correlated with a single suture fusion.

Stem Cell-Enriched Fat Grafts Versus Autologous Fat Grafts for Facial Reconstruction: A Systematic Review and Meta-analysis

OBJECTIVE

The aim of the study is to compare the outcomes of stem cell-enrichment fat grafting versus routine fat grafting for facial reconstruction purposes.

METHODS

A systematic review and meta-analysis were performed as per the Preferred Reporting Items for Systematic Reviews and Meta-analyses Guidelines and a search of electronic information was conducted to identify all randomized controlled trials, case control studies, and cohort studies comparing the outcomes of stem cell enrichment fat grafting versus routine fat grafting for facial reconstruction purposes. Volume retention and infection rate were primary outcome measures. Secondary outcome measures included patient satisfaction postsurgery, redness and swelling, fat necrosis, cysts, as well as operation time. Fixed and random effects modeling was used for the analysis.

RESULTS

Eight studies enrolling 275 subjects were selected. There was a significant difference between the stem cell enrichment fat grafting and routine grafting groups in terms of mean volume retention (standardized mean difference, 2.49; P < 0.00001). However, there was no significant difference between the 2 groups in the rate of infection (odds ratio, 0.36; P = 0.30). For all secondary outcomes, the intervention group had similar results compared with the control group except for the operation time, which was shorter in the latter.

CONCLUSIONS

Stem cell-enriched fat grafting is a superior option when compared with the routine fat grafting for facial reconstruction surgery because it improves the mean volume retention and does not worsen patient satisfaction and surgical complications.

Pyramidal multiple-theory (multi-type, multi-method and multi-layer) for facial fat grafting

BACKGROUND

Age-related changes to the face pertinent anatomy and important aspects of autologous fat grafting have been widely applied in facial rejuvenation. Various types of autologous fat products (Macrofat, Microfat, SEFF, nanofat, and SVF-gel) with different properties and applicabilities have been introduced and available for surgeons.

METHODS

Key differences between common techniques for fat processing and infiltration. Develop a plan for patients based on site-specific facial anatomical zones, we suggested a pyramidal multiple-theory (multi-type, multi-method and multi-layer) for facial fat grafting. Based on the complicated mechanism of the face decrepitude in different layers of facial soft tissue, autologous fat products with various particle sizes and components into different layers.

RESULTS

Fifty-eight patients underwent this facial fat grafting strategy from June 2020 to Jan 2022. All achieved cosmetic improvements, with higher patients' satisfaction, and minor complications. Our facial fat grafting strategy takes advantage of different fat products and is able to address the physiological tissue changes during aging, more properly and targetedly, than the traditional facial fat grafting.

CONCLUSIONS

Fat grafting to the face aids in volume restoration and rejuvenation, thereby addressing soft-tissue atrophy associated with the aging face, acquired conditions, or congenital malformations. The technique described as "lipo-tumescence" has been successfully used in the breast and other regions of the body that have radiation damage and is discussed in this article specifically for the face and neck.

Effective and economical cell therapy for hair regeneration

We reviewed and summarized the latest reports on the characteristics of stem cells and follicular cells that are under development for hair loss treatment. Compared with conventional medicine, cell therapy could be effective in the long term with a single treatment while having mild adverse effects. Adipose-derived stem cells (ASCs) have the advantages of easy access and large isolation amount compared with dermal papilla cells (DPCs) and dermal sheath cup cells (DSCs), and promote hair growth through the paracrine effect. ASCs have a poor potential in hair neogenesis, therefore, methods to enhance trichogenecity of ASCs should be developed. DSCs can be isolated from the peribulbar dermal sheath cup, while having immune tolerance, and hair inductivity. Therefore, DSCs were first developed and finished the phase II clinical trial; however, the hair growth was not satisfactory. Considering that a single injection of DSCs is effective for at least 9 months in the clinical setting, they can be an alternative therapy for hair regeneration. Though DPCs are not yet studied in clinical trials, we should pay attention to DPCs, as hair loss is associated with gradual reduction of DPCs and DP cell numbers fluctuate over the hair cycle. DPCs could make new hair follicles with epidermal cells, and have an immunomodulatory function to enable allogeneic transplantation. In addition, we can expand large quantities of DPCs with hair inductivity using spheroid culture, hypoxia condition, and growth factor supplement. 'Off-the-shelf' DPC therapy could be effective and economical, and therefore promising for hair regeneration.

The Effect of Centrifuge Duration on Fat Graft Survival

Background Although fat grafts are widely used for reconstruction and aesthetic purposes, their survival rates differ significantly. Centrifugation is one of the methods used to increase the survival of fat grafts. However, experimental studies examining the long-term outcomes of centrifugation duration are currently limited. Thus, in the present study, the effects of centrifugation duration on the survival of fat grafts were assessed using an animal model.

Methods Thirty Sprague Dawley rats were included in the study and fat grafts were obtained from each specimen by excision from inguinal fat pads. Preparation protocols were administered as an en-bloc fat graft in Group 1, minced fat graft in Group 2, and fat graft centrifuged at 1,054 ×g for 2 minutes, 3 minutes, and 4 minutes in Group 3, 4, and 5, respectively. After 12 weeks of follow-up, grafts were harvested and were subjected to histopathological evaluation based on an established scoring system.

Results En-block fat grafts were associated with necrosis, fibrosis, inflammation, vacuole formation, and alterations in adipocyte morphology. Among the three centrifugation groups, Group 3 demonstrated the best adipocyte viability and vascularity. However, graft weights decreased in all experimental groups.

Conclusion The centrifugation process may have positive effects on adipocyte survival by means of purifying the fat graft and increasing adipocyte concentration. When the centrifugal durations were compared, 3-minute centrifuge yielded the most favorable results.

Rhinoplasty with Simultaneous Autologous Full-Face Fat Transfer for Asian Facial Contouring Balance: A Retrospective Study

BACKGROUND

The aesthetic facial contouring procedures have gained an increasing popularity in the Asian population. Nevertheless, currently, there are few specific literature assessments and studies on the outcomes of rhinoplasty combined with full-face fat graft contouring. To conduct an objective evaluation of the efficacy of Asian rhinoplasty combined with autologous facial fat transfer in terms of 3-dimensional measurement and patient-reported outcomes.

METHODS

Patients who underwent rhinoplasty combined with full-face fat transfer for facial contouring between January 2016 and July 2019 were recruited in the study. The preoperative and postoperative clinical variables and 3-dimensional measurement of patients were also collected. The satisfaction outcome of surgeons and patients was assessed.

RESULTS

Twenty patients completed rhinoplasty with full-face fat transfer. The average postoperative follow-up was 10.2 months (range 6-24 months). The nasal length, and the nasal protrusion rate were significantly increased (p < 0.05) after surgery, and the median number of nasolabial angles decreased from 106° to 101°, which was closer to the aesthetic standard of 90°-100°. The topographical projection images of whole face indicated that the volume of frontal, temporal, inner cheek and chin regions were increased obviously. All cases received satisfaction outcome based on surgeons' satisfaction scale, ROE scale, FACE-Q overall facial satisfaction scale, and FACE-Q Rhinoplasty scale. Additionally, no patients had intraoperative or postoperative complications.

CONCLUSIONS

Rhinoplasty combined with full-face fat transfer is a reliable and effective method of augmenting and contouring the facial convexity in the Asian populations.

Modified transcervical lipofilling of the base of the tongue under local anaesthesia: Case series

Laryngeal carcinoma represents one-third of all head and neck cancers and is burdened by significant morbidity and mortality for advanced-stage disease. Surgical treatments, including Open Partial Horizontal Laryngectomy (OPHL), are often followed by long-lasting swallowing rehabilitation and more rarely, persistent dysphagia. Some authors reported single cases, successfully treated with fat injection of the base of tongue, but nowadays, a standardized technique has never been described so far. We provide a step-by-step technique description of the trans-cervical lipofilling of the base of the tongue (BOT) under local anaesthesia in a case series of three patients. The functional results have been evaluated with a videofluoroscopic study of deglutition and Penetration-Aspiration Score. The procedure was well tolerated; all patients were discharged after 24 hours without any majorcomplications. After six months, all patients had a steady improvement in swallowing. During follow-up, the videofluoroscopic study of deglutition confirmed a sensitive amelioration of the Penetration-Aspiration Score and an empowered base of tongue retropulsion. Finally, the lipofilling of the BOT under local anaesthesia showed to be a feasible, and reproducible procedure, for dysphagia after OPHLs.

Low Negative Pressure Combined With Supertumescence Microliposuction as a New Method for Repairing Facial Fat Overfilling: A Case Series of 32 Patients

BACKGROUND

Face fat overfilling sometimes occurs and is unfortunately very difficult to repair.

OBJECTIVES

The aim of this study was to report initial experience of microliposuction with low negative pressure combined with supertumescence (LNPST) in a case series of 32 patients.

METHODS

The LNPST microliposuction was performed in 32 patients aged 22 to 41 years (mean [standard deviation] age, 29.6 [4.9] years) with facial overfilling. Discomfort and bleeding were monitored intraoperatively by 2 independent plastic surgeons, who used a grading system to record the results. All patients were followed-up for hematoma within 1 week postoperatively and for skin numbness and muscle paralysis at 1 week and 3 months postoperatively. In addition, at 6 months postoperatively, patient satisfaction with the postoperative aesthetic effects was analyzed by FACE-Q questionnaire.

RESULTS

All patients successfully completed the operation under local anesthesia. The mean intraoperative discomfort and blood-loss scores were 1.69 [0.62] and 1.22 [0.41], respectively. The hematoma score was 1.13 [0.34] within 1 week. Other scores included postoperative skin numbness (1 week, 1.96 [0.62]; 3 months, 1.13 [0.33]) and postoperative muscle paralysis (1 week, 1.22 [0.51]; 3 months, 1.0 [0]). Overall, neither skin necrosis nor serious complications requiring revision surgery occurred. Seventy-two percent of the patients (n = 23) answered the FACE-Q questionnaire and the score was 21.8 (1.7), covering satisfaction with the outcome score into a standard score (81.7 [15.1], from 0 to 100), which verified the high satisfaction rate.

CONCLUSIONS

LNPST technology is a safe and effective method for repair of facial fat overfilling, with less bleeding, less nerve injury, fewer complications, and high patient satisfaction.

The Utilization Of Poly-L-Lactic Acid As A Safe And Reliable Method For Volume Maintenance After Facelift Surgery With Fat Grafting

Background

For age-related volume loss, fat grafting is now recognized as an integral adjunctive procedure with facelift surgery. However, when there is continued and unpredicted volume loss postoperatively, the surgeon has limited options for restoring this lost volume.

Objectives

Poly-l-lactic acid (PLLA) is a proven biostimulator that creates volumetric enhancement. This study is undertaken to demonstrate that PLLA is a safe and efficacious option for maintenance of post-facelift volume loss.

Methods

A retrospective review was conducted to identify all patients who underwent facelift surgery with fat grafting and postoperative PLLA injections from 2010 to 2018 by a single surgeon. Demographic and clinical data were collected and analyzed.

Results

This review identified a total of 241 patients who had undergone a facelift with fat grafting and PLLA injections. Of these, 190 patients were treated with PLLA after facelift and fat grafting, while 51 patients received PLLA injections before their operation. We identified 5 common indications for use of PLLA after facelift surgery and fat grafting. These included unexplained early fat graft loss, significant weight loss in the postoperative period, normal aging process, and patients who had a high perioperative lean body mass. Additionally, PLLA was found to be an effective volumizer for site-specific areas that did not undergo fat grafting during the initial operation. There were no complications reported from the PLLA injections related to nodule formation, papules, or granulomas.

Conclusions

The high degree of variability in the survival of fat grafts with facelift surgery is an accepted reality. PLLA represents a safe and highly effective solution to restore volume loss in patients who have undergone facelifts with fat grafting.

Autologous Fat Grafting in Plastic and Reconstructive Surgery: An Historical Perspective

Autologous fat grafting (AFG or lipofilling) is a common technique used in plastic and reconstructive surgery that involves the transfer of autologous fat tissue from one region of the body to another. The indications and techniques of AFG have changed dramatically over the years. We recount the historic milestones to the current state.

Fat injection and its clinical applications

Fat injection has been in application for more than two decades, and its usefulness has been well documented. In our article, we want to highlight the various applications and usefulness of this versatile technique. We also want to showcase the methods to ensure good results and maximize the uptake of fat grafts with minimal absorption. Our results in our series of 110 consecutive cases have been very encouraging, with excellent patient satisfaction.

Minimal Incision Lower Augmentation Blepharoplasty: 3 Simple Steps to Facial Mid-Term Rejuvenation

Background

The practice of removing skin and fatty tissue from the lower eyelid does not accommodate the different forms of facial aging. Therefore, techniques that encompass the recovery of facial volumes are common. Currently, when isolated lower blepharoplasty is performed, it does not take into account that mid-face rejuvenation is simultaneously possible. Furthermore, it is not always necessary to make incisions along the entire lash line, because this may be minimal in good candidates.

Objectives

This article presents a selection of patients who underwent augmentation lower blepharoplasty for the rejuvenation of the middle third of the face associated with the periorbital area, which is a modified traditional lower blepharoplasty technique performed with minimal incisions and fat grafting.

Methods

A retrospective study was conducted on 160 patients who underwent lower augmentation blepharoplasty performed by the authors from July 2017 to March 2021. The small incision utilized is approximately 15 to 18 mm and does not reach the ends or edges of the lower eyelid. The procedure is accompanied by fat grafting in the area of the middle third of the face. Finally, a Likert test was conducted to assess satisfaction.

Results

The patients presented a noticeable improvement, obtaining more attractive and youthful results from the middle third of the face. There were no major complications, and the patient outcomes were satisfactory.

Conclusions

Augmentation lower blepharoplasty with minimal incisions can be a useful alternative for selected patients who seek to jointly rejuvenate the middle third of the face.

Asian Face Lift with the Composite Face Lift Technique

BACKGROUND

The composite face lift is becoming increasingly popular following recent advances in understanding of facial anatomy that enable safe sub-superficial musculoaponeurotic system (SMAS) dissection. This article presents the authors' technique for composite face lift in Asian patients and reviews their experience and outcome with this procedure.

METHODS

Composite face lifts were performed on 128 Asian patients between January of 2010 and June of 2020. Ninety-four were primary face lifts, and 34 were secondary or tertiary face lifts. The authors' surgical technique and adaptations for the specific requirements of Asian patients are described in detail. The mean follow-up was 26 months (range, 6 to 108 months). Fat grafting was an integral part of our procedure, with 95 percent having concomitant facial fat grafting with their face lift.

RESULTS

Patients were followed up in accordance with a standardized schedule. The majority of patients reported high satisfaction with the aesthetic outcome of the technique, with natural, long-lasting results. The face lift plane of dissection is through the facial soft-tissue spaces, which provide atraumatic sub-SMAS access with precise release of the intervening retaining ligaments for effective flap mobilization. By emphasizing tension on the composite flap with no tension on the skin closure, the scars were discrete in the great majority of patients. Complications were few, with no hematomas or skin flap necrosis. The temporary nerve injury rate was 1.5 percent, with no patient having a permanent nerve injury.

CONCLUSION

The composite face lift is an ideal technique for Asian patients, as it delivers natural, long-lasting results; a quick recovery; and high patient satisfaction.

Regen Fat Code: A Standardized Protocol for Facial Volumetry and Rejuvenation

BACKGROUND

Facial aging is a degenerative process that impairs contour and angle prominence. Rejuvenation is based on tissue replacement, volumization of the atrophic areas, and improving flaccidity and cutaneous photoaging.

OBJECTIVES

The aim of this study was to apply structural fat grafting to manage volumetric deficits of the face, following a new systematic protocol called "Regen Fat Code" (RF Code) that was created to standardize structural lipotransfer methods.

METHODS

This is a prospective clinical trial involving 80 healthy candidates for facial rejuvenation who were split into 2 groups. Group A underwent only structural lipotransfer; Group B underwent replacement of deep facial structures by face-lifting plus structural lipotransfer. Structural lipotransfer followed the protocol "RF Code" and 3 clinical tools were adopted for pre- and postoperative facial volumetric analysis.

RESULTS

Total volume (mL) of lipotransfer in Groups A and B ranged between 1 and 20 mL (mean [standard deviation], 12 [5] mL), distributed to the different areas as follows: nasolabial fold, 3.32 [0.92] mL; superior lip, 2.0 [0.62] mL; inferior lip, 2.76 [0.71] mL; malar, 8.51 [5.25] mL; inferior eyelid, 1.2 [0.54] mL; and chin, 7.18 [1.99] mL. Areas with less mobility showed a lower absorption index than dynamic areas.

CONCLUSIONS

The development of the RF Code protocol demonstrated the potential of grouping many parameters based on the lipotransfer method used to volumize and regenerate atrophic areas of the face. The protocol is easy to apply, and allows different volumizing and regenerative effects to be proposed, according to the demands of each surgical area.

The Effects of Lipoaspirate-Derived Fibrous Tissue on Survival Quality and Mechanical Property of Fat Grafts

BACKGROUND

Fibrous connective tissue (referred to as fiber) in lipoaspirates would be discarded before lipotransfer in case of cannula blockage. However, the fiber contains extracellular matrix which provide structure support and is rich in stromal vascular fractions (SVFs). Removal of the fiber might theoretically affect the survival quality and mechanical properties of fat grafts. But there is few evidence in vivo and vitro about how the fiber affects the fat grafts.

OBJECTIVE

To assess the effect of fibers on the survival quality and mechanical property of fat grafts.

METHODS

The SVFs in both fat and fiber were obtained by collagenase digestion for cells counting and comparison. Three groups were designed according to the different proportions of fat and fiber: the fat group (100% fat), the mixed group (50% fat, 50% fiber in volume ratio), and the fiber group (100% fiber). Three groups of grafts were transplanted in vivo to evaluate the differences in volume retention rate, histological characteristics and mechanical properties.

RESULTS

The amount of SVF cells in fibers (3.47 ± 1.49 × 104 cells/mL) was significantly lower than that in fat (12.3 ± 4.95 × 104 cells/mL) (P < 0.05). Grafts in the mixed group and the fiber group showed an increase of volume retention at week 4, but the fiber content showed no significant effects on the volume retention of grafts in three groups at week 12. Elasticity modulus of grafts in the fat group was higher than that in the fiber group and the mixed group at week 4 and 8, the fiber content showed no significant effects on the elasticity modulus of grafts in three groups at week 12. The addition of the fiber reduced the inflammation, cysts, fibrosis, and capillaries density of the grafts.

CONCLUSIONS

There were few SVF cells in the fiber. When it was mixed with fat in different proportions and transplanted in vivo, the content of fiber showed no significantly different effects on the long-term volume retention and mechanical property of fat grafts. Due to the risk of blockage, it is recommended to discard the fiber in lipoaspirates.

Craniofrontonasal dysplasia: hypertelorism correction in late presenting patients

BACKGROUND

Craniofrontonasal dysplasia (CFND) is a rare congenital craniofacial syndrome characterized by single suture synostosis, hypertelorism, other clinical facial features, and abnormalities in the upper extremities. There are only a few studies in the applicable literature that address hypertelorism management for CFND patients and outcomes and complication rates.

METHODS

A retrospective study was performed on consecutive late presenting CFND patients referred to our hospital with substantially completed craniofacial skeleton growth, who underwent hypertelorism correction between 2007 and 2019 following intracranial pressure screening, and who received at least 1 year of follow-up care. None of the patients in this study underwent prior craniofacial surgery. Only those patients with a confirmed mutation of the EFNB1 gene were included in this study. All patients in this study underwent hypertelorism correction by facial bipartition or box osteotomy.

RESULTS

A total of ten late presenting CFND patients (all female) were treated at our hospital during the study period. None of the patients presented signs of elevated intracranial pressure. The average patient age at hypertelorism correction was 13.4 ± 7.68 years of age. Major complications, defined as complications requiring a return to the operating room, were limited to infection of the frontal bone, which required partial bone removal, and cerebrospinal fluid (CSF) leak, which was completely resolved by insertion of a lumbar shunt for a 7-day period.

CONCLUSION

The absence of elevated intracranial pressure enables hypertelorism correction in late presenting CFND patients via facial bipartition or box osteotomy without the need for additional operations that provide for cranial expansion.

The Ideal Lips: Lessons Learnt from the Literature

Defining the ideal dimensions and proportions of the human face has been attempted for centuries, popularised in the Renaissance period by artists including Leonardo Da Vinci. The lips are part of the lower third of the face and are central to lower face aesthetics and the overall symmetry of the face. They also place an important part in conveying facial emotions and expressions. Full lips with well-defined Cupid's bow have always been associated with youth and beauty. The approval of hyaluronic acid use for tissue augmentation and the prevalence of social media have caused an exponential increase in lip augmentation procedures (Linkov et al. in Arch Plast Surg 46(3):248-254, 2019), as such researchers and aestheticians have focused on characterising the ideal lips mathematically to help guide clinicians. This narrative review will summarise the available evidence in the literature pertaining to the ideal lips, taking into account age, ethnicity and gender differences.

Regenerative and stem cell-based techniques for facial rejuvenation

This review discusses the most novel ideas and modalities being incorporated into facial rejuvenation. Recent innovative techniques include the use of regenerative stem cell techniques and regeneration supportive modalities such as nano-technology or gene therapies. This review aims to investigate approaches that are less well known and lacking established evidence in order to proactively study these techniques prior to them becoming popularized. These applications and relevant research were reviewed in the context of both surgical and non-surgical modalities in clinical practice. Future directions include the concept of "precision cosmetic medicine" utilizing gene editing and cellular therapies to tailor rejuvenation techniques based on each individual's genetic make-up and therefore needs.

Autologous Craniofacial Fat Grafting in the Irradiated Field

ABSTRACT

Autologous fat grafting has been used as a reconstructive modality following the treatment of head and neck malignancy. However, it has been criticized for poor graft retention and unpredictable results, which may be further compromised by prior radiation therapy. This systematic review will consolidate the literature on autologous fat grafting in the previously irradiated craniofacial region and report its effects on aesthetic and functional outcomes, volume resorption, and postoperative complications. A computerized search of Medline, Embase, Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health Literature, and Web of Science was performed. Screening and data extraction were performed in duplicate. Data were extracted from the included articles, and outcomes were analyzed categorically. Sixty patients from six studies were included. Mean age was 46.06 years (range 13-73) and 37.5% were female. All studies used the Coleman technique fat grafting or a modified version. A total of 94.9% of patients had significant improvement in aesthetic outcomes and 86.1% in the study specific functional outcomes. Mean graft volume resorption was 41% (range 20%-62%) and there were three (5%) postoperative complications. Autologous fat grafting is increasingly being used to optimize aesthetic outcome following head and neck reconstruction, even in the presence of prior radiation treatment. Although the literature to date is encouraging, the heterogeneity in patient population, intervention, outcome measures, and time horizon limit our ability to draw conclusions about the success of craniofacial fat grafting in the irradiated field. Future research should include a large comparative study as well as a protocol for standardizing outcome measures in this population.

Quality and Quantity-Cultured Human Mononuclear Cells Improve Human Fat Graft Vascularization and Survival in an In Vivo Murine Experimental Model

BACKGROUND

Fat graft ischemia impedes us from having satisfying long-term results. The quality and quantity culture is a 1-week cell culture that increases the vasculogenic potential of peripheral blood mononuclear cells (PBMNC). This in vivo murine model investigates whether enrichment with quality and quantity-cultured human mononuclear cells (MNC-QQ) improves the vascularization in the human fat graft and whether this decreases the tissue loss.

METHODS

Human adipose tissue, PBMNC, MNC-QQ, and stromal vascular fraction were prepared. First, PBMNC, MNC-QQ, and stromal vascular fraction were compared in vitro for vasculogenic potential by endothelial progenitor cell colony-forming and culture assays. Second, 0.25-g fat grafts were created with 1 × 106 PBMNC (n = 16), 1 × 106 MNC-QQ (n = 16), 1 × 106 stromal vascular fraction (n = 16), or phosphate-buffered saline as control (n = 16) before grafting in BALB/c nude mice. Grafts were analyzed for weight persistence, vessel formation by CD31 immunohistochemistry, and angiogenic markers by quantitative polymerase chain reaction.

RESULTS

MNC-QQ develop more definitive endothelial progenitor cell colonies and more functional endothelial progenitor cells compared to PBMNC and stromal vascular fraction. Weight persistence after 7 weeks was significantly higher in grafts with MNC-QQ (89.8 ± 3.5 percent) or stromal vascular fraction (90.1 ± 4.2 percent) compared with control (70.4 ± 6.3 percent; p < 0.05). MNC-QQ-enriched grafts had the highest vessel density (96.6 ± 6.5 vessels/mm2; control, 70.4 ± 5.6 vessels/mm2; p < 0.05). MNC-QQ exerted a direct vasculogenic effect through vascular integration and a potential paracrine vascular endothelial growth factor-mediated effect.

CONCLUSION

Quality and quantity-cultured human mononuclear cells containing endothelial progenitor cells stimulate fat graft vascularization and enhance graft survival in a rodent recipient.

Treacher Collins Mandibular Distraction

Treacher Collins syndrome (TCS) is a genetic disorder that presents with a variety of craniofacial deformities. One classic feature of TCS is a steep, counterclockwise rotation of the occlusal plane, and microretrognathia with bony deficiencies in both the body and ramus of the mandible. This morphology commonly necessitates reconstruction by the craniofacial surgeon. This article discusses strategies and considerations for surgically correcting the mandibular deformity associated with TCS using mandibular distraction osteogenesis and other related techniques. The proper implementation of these techniques can yield excellent results that greatly improve quality of life in this challenging patient population.

Secondary Treatment of Cleft Lip Correction Sequelae With Percutaneous Needleotomy, Autologous Fat Grafting, and Local Flaps: An Integrated Approach

INTRODUCTION

Cleft lip and/or palate (CL/P) is the most common congenital craniofacial malformation. The severity of the anatomic deformity is highly variable and different techniques can be employed depending on whether the defect is unilateral or bilateral, complete or incomplete. Patients usually undergo multiple steps of reconstruction throughout childhood and adolescence and, for this reason, secondary deformities of the nasolabial region of the midface may ensue. Considering our experience in the treatment of scars, we opted to correct the cleft lip surgery sequelae not only with local flaps/scar revisions, but we decided to add the use of the autologous fat grafting (AFG) to induce a regenerative effect in these young patients.

MATERIALS AND METHODS

In this study we present the results obtained from a series of 12 consecutive Caucasian patients aged from 23 to 44 years with widened paramedian lip scars secondary to cleft lip reconstruction surgery, treated with a combination of needle-induced lysis of the scar tissue and AFG from January 2013 to December 2018.

RESULTS

After the procedure we observed an overall improvement in the quality of the scar tissue, in the function of mimic features, in the symmetry and cosmetics of the lower third of the nose. Patients' satisfaction was excellent. Results were long lasting and remained virtually unchanged after 1 year of follow-up.

CONCLUSIONS

Scar release by needle, AFG and local flaps are excellent tools for the treatment of cleft lip correction sequelae, but the combination of these surgical techniques can lead to even better results.Level of Evidence: Level V.

Facial Contouring Surgery Using Facelift Approach

BACKGROUND

In Asian women who undergo facelift surgery, satisfying results are achieved for facial rhytides, but there have been complaints concerning malar prominence and mandible angle region postoperatively. Anatomically, compared with the Caucasians, the Asians have a thick skin and a wide and short facial geometry. The Asians generally have a protruded zygoma and prominent mandible angles; accordingly, their bony contouring surgery that is the base frame in facelift must be considered. The authors aimed to investigate the effects of performing facial contouring surgery and facelift simultaneously to achieve oval facial contour and youthful face.

METHODS

The authors assessed 21 Asian women who simultaneously underwent facial contouring surgery with facelift between March 2014 and March 2018. The clinical results were assessed based on preoperative and postoperative photographs and the global aesthetic improvement scale score.

RESULTS

Surgery was successful in all patients. Postoperatively, improvements in facial rhytides and appropriate facial contour were achieved. All patients were satisfied with the outcomes. Some patients experienced short-term complication; however, these complications improved. Serious long-term complications were not noted.

CONCLUSIONS

Highly satisfying outcomes can be achieved with combined facial contouring surgery and facelift for Asian women with a wide face.

A Step in the Right Direction: A Prospective Randomized, Controlled Crossover Trial of Autologous Fat Grafting for Rejuvenation of the Heel

BACKGROUND

The shock-absorbing soft tissues of the heel are composed of dermis and specialized fat pads. Heel fat pad atrophy is common and can be painful and debilitating. In our previous work, autologous fat grafting was effective for treating pain from forefoot fat pad atrophy.

OBJECTIVES

The authors hypothesized that autologous fat grafting to the heel would relieve pain and improve function in patients with heel fat pad atrophy.

METHODS

Patients with heel fat pad atrophy and associated pain were recruited and randomized into 2 groups. Group 1 received autologous fat grafting on enrollment and was followed for 2 years. Group 2 received offloading and activity modification for 1 year, then crossed over, underwent autologous fat grafting, and was followed for 1 year afterward. Outcome measures included ultrasound-measured fat pad and dermal thickness; pedobarograph-measured foot pressures and forces; and patient-reported outcomes as measured by the Manchester Foot Pain and Disability Index.

RESULTS

Thirteen patients met the inclusion criteria and completed the study. Seven (12 affected feet) were randomized into Group 1; and 6 (9 affected feet) were randomized into Group 2. The average age was 55 years and BMI was 30.5 kg/m2. Demographics did not significantly differ between groups. Heel fat pad thickness increased after autologous fat grafting but returned to baseline at 6 months. However, autologous fat grafting increased dermal thickness significantly and also increased fat pad thickness under a compressive load compared with controls at 6 and 12 months. Foot pain, function, and appearance were also significantly improved compared with controls at 6 and 12 months.

CONCLUSIONS

Autologous fat grafting improved patient-reported foot pain, function, and appearance and may rejuvenate local soft tissues in patients with heel fat pad atrophy.

Changing the Paradigm of Craniofacial Reconstruction: A Prospective Clinical Trial of Autologous Fat Transfer for Craniofacial Deformities

OBJECTIVE

This study aimed to prospectively assess outcomes for surgical autologous fat transfer (AFT) applied for traumatic and postsurgical craniofacial deformities. The minimally invasive nature of AFT has potential for reduced risk and superior outcomes compared with current reconstructive options.

BACKGROUND

Craniofacial deformities have functional and psychosocial sequelae and can profoundly affect quality of life. Traditional reconstructive options are invasive, invasive, complex, and often lack precision in outcomes. Although AFT is safe, effective, and minimally invasive, only anecdotal evidence exists for reconstruction of craniofacial deformities.

METHODS

In this Institutional Review Board-approved prospective cohort study, 20 subjects underwent AFT (average volume: 23.9 ± 13.2 mL). Volume retention over time was determined using high-resolution computed tomography. Flow cytometry was used to assess cellular subpopulations and viability in the stromal vascular fraction. Quality of life assessments were performed. After the completion of 9-month follow-up, 5 subjects were enrolled for a second treatment.

RESULTS

No serious adverse events occurred. Volume retention averaged 63 ± 17% at 9 months. Three-month retention strongly predicted 9-month retention (r=0.996, P < 0.0001). There was no correlation between the total volume injected and retention. Patients undergoing a second procedure had similar volume retention as the first (P = 0.05). Age, sex, body mass index, and stromal vascular fraction cellular composition did not impact retention. Surprisingly, former smokers had greater volume retention at 9 months compared with nonsmokers (74.4% vs 56.2%, P = 0.009). Satisfaction with physical appearance (P = 0.002), social relationships (P = 0.02), and social functioning quality of life (P = 0.05) improved from baseline to 9 months.

CONCLUSIONS

For craniofacial defects, AFT is less invasive and safer than traditional reconstructive options. It is effective, predictable, and reaches volume stability at 3 months. Patient-reported outcomes demonstrate a positive life-changing impact.

Ultrasound to Improve the Safety and Efficacy of Lipofilling of the Temples

BACKGROUND

Autologous fat is known for a reliable and natural safety profile, but complications do occur-even serious vascular adverse events.

OBJECTIVES

The authors sought to examine doppler-ultrasound (DUS) imaging for the harvesting and subsequent facial implantation of autologous fat tissue.

METHODS

All patients underwent lipofilling treatment of the temporal fosse of the face. DUS examination was performed for preprocedural vascular mapping and imaging of previously injected (permanent) fillers. In addition, the injection of autologous fat was performed DUS-guided.

RESULTS

Twenty patients (all female; mean age, 57.9 years; range, 35-64 years). DUS examination showed that 16 of the 20 patients (80%) had been injected with resorbable or nonresorbable fillers elsewhere in the past. The temporal artery could be visualized and avoided in all cases. An average of 1.1 cc of autologous fat was injected in the temporal fossa per side. One case of edema and nodules was described, but no other adverse events were reported.

CONCLUSIONS

The utilization of DUS can add valuable information to a lipofilling procedure and should be considered an integral part of a safe lipofilling treatment.

Skin Necrosis and Vision Loss or Impairment After Facial Filler Injection

Purpose of the present study is to objectively evaluate the number of severe vascular complications, represented by skin necrosis and vision loss or impairment, following facial filler injection. The investigators implemented a review of the literature including articles published on PubMed database without limitation about year of publication, including all reports concerning skin necrosis and vision loss or impairment related to the injection of fillers for cosmetic uses. The search highlighted 45 articles and a total of 164 cases of skin necrosis and vision loss or impairment after injection of different substances. The injection site most frequently associated with complications was the nose (44.5%), followed by glabella (21%), nasolabial fold (15%), and forehead (10%). Results of the present study suggest that injectable filler can cause severe complications even in expertized hands. Treatments in the new defined "Dangerous triangle" must be carefully carried out. Despite our expectations, the highest rates of sever adverse events have been associated with autologous fat transfer practice.

Lipofilling in Breast Oncological Surgery: A Safe Opportunity or Risk for Cancer Recurrence?

Lipofilling (LF) is a largely employed technique in reconstructive and esthetic breast surgery. Over the years, it has demonstrated to be extremely useful for treatment of soft tissue defects after demolitive or conservative breast cancer surgery and different procedures have been developed to improve the survival of transplanted fat graft. The regenerative potential of LF is attributed to the multipotent stem cells found in large quantity in adipose tissue. However, a growing body of pre-clinical evidence shows that adipocytes and adipose-derived stromal cells may have pro-tumorigenic potential. Despite no clear indication from clinical studies has demonstrated an increased risk of cancer recurrence upon LF, these observations challenge the oncologic safety of the procedure. This review aims to provide an updated overview of both the clinical and the pre-clinical indications to the suitability and safety of LF in breast oncological surgery. Cellular and molecular players in the crosstalk between adipose tissue and cancer are described, and heterogeneous contradictory results are discussed, highlighting that important issues still remain to be solved to get a clear understanding of LF safety in breast cancer patients.

Volume Retention After Facial Fat Grafting and Relevant Factors: A Systematic Review and Meta-analysis

BACKGROUND

Autologous fat grafting is common in facial reconstructive and cosmetic surgeries; the most important drawbacks are the high absorption rate and unpredictable volume retention rate. Surgeons usually make clinical judgements based on their own experience. Therefore, this study aimed to systematically and quantitatively review the volume retention rate of facial autologous fat grafting and analyse the relevant influencing factors.

METHODS

A systematic literature review was performed using the Medline, EMBASE, Cochrane Library, and Web of Science databases in October 2019 for articles that reported objectively measured volume retention rates of facial fat grafting. Patient characteristics, fat graft volumetric data, and complications were collected. A meta-analysis using a random-effects model was conducted to pool the estimated fat retention rate. Relevant factors were analysed and reviewed on the basis of subgroups.

RESULTS

We included 27 studies involving 1011 patients with facial fat grafting. The volume retention rate varied from 26 to 83%, with a mean follow-up of 3-24 months. The overall pooled retention rate was 47% (95% CI 41-53%). The volume measurement method significantly influenced the reported retention rate. A trend towards better retention was found for secondary fat grafting procedures and patients with congenital deformities. Only 2.8% of all patients had complications.

CONCLUSION

The exact percentage of facial fat grafts retained is currently unpredictable; the reported rate varies with different estimation methods. This review analysed studies that provided objectively measured volume retention rates, the pooled average percentage of facial fat graft retention (47%, 95% CI 41-53%), and relevant factors.

An Extended 45-year Long-term Follow-up on a 1-13 Rare Facial Cleft Patient

ABSTRACT

We present here the unique case of a patient with a Tessier 1-13 rare facial cleft accompanied by cleft lip and palate and Tessier grade 2 hypertelorism. The patient described in this article has a twin brother who shares a number of genetic traits and physical features but does not present facial cleft or hypertelorism. The 45-year follow-up in this case is believed to be the longest follow-up to date to have been reported in the literature, and sheds significant light on the importance of extended longitudinal follow-up to maximize patient outcomes.

Custom-Made Zirconium Dioxide Implants for Craniofacial Bone Reconstruction

Reconstruction of the facial skeleton is challenging for surgeons because of difficulties in proper shape restoration and maintenance of the proper long-term effect. ZrO₂ implant application can be a solution with many advantages (e.g., osseointegration, stability, and radio-opaqueness) and lacks the disadvantages of other biomaterials (e.g., metalosis, radiotransparency, and no osseointegration) or autologous bone (e.g., morbidity, resorption, and low accuracy). We aimed to evaluate the possibility of using ZrO₂ implants as a new application of this material for craniofacial bone defect reconstruction. First, osteoblast (skeleton-related cell) cytotoxicity and genotoxicity were determined in vitro by comparing ZrO₂ implants and alumina particle air-abraded ZrO₂ implants to the following: 1. a titanium alloy (standard material); 2. ultrahigh-molecular-weight polyethylene (a modern material used in orbital surgery); 3. a negative control (minimally cytotoxic or genotoxic agent action); 4. a positive control (maximally cytotoxic or genotoxic agent action). Next, 14 custom in vivo clinical ZrO₂ implants were manufactured for post-traumatologic periorbital region reconstruction. The soft tissue position improvement in photogrammetry was recorded, and clinical follow-up was conducted at least 6 years postoperatively. All the investigated materials revealed no cytotoxicity. Alumina particle air-abraded ZrO2 implants showed genotoxicity compared to those without subjection to air abrasion ZrO₂, which were not genotoxic. The 6-month and 6- to 8-year clinical results were aesthetic and stable. Skeleton reconstructions using osseointegrated, radio-opaque, personalized implants comprising ZrO₂ material are the next option for craniofacial surgery.

Fat Augmentation as Adjunct to CORE Facelift Surgery

Ruling out cases with strong jawlines, well-developed mid-cheek regions, and good fat presence, if done artistically, fat augmentation strongly assists midface definition and can replenish hollowed regions of the face. This is particularly true for candidates with low bodyfat or smaller skull structures. Hence, fat grafting is a strong adjunct to conventional excisional techniques in facial rejuvenation surgery, regardless of experience, technique, or geographical embedding. While CORE facelift techniques remain the golden standard that define the top level of facelift surgery, fat augmentation has its unique place along the full stretch of an individual surgeon's learning scope, as it will potentially improve results regardless of where one stands.

Autologous Fat Grafting in Young Patients: A Simple and Effective Way to Achieve Facial Balance

GOALS/PURPOSE

Rhinoplasty is the most common procedure seen in the teenage population. Many of these patients have facial imbalance both recognized and unrecognized by the individual and family. Most often it involves chin or midface deficiency. When the discussion involves the possibility of additional surgery, such as an alloplastic chin implant or a surgical osteotomy, the conversation halts because the patient and family seek a simpler solution.Autologous fat transfer is a useful adjunct to achieve facial balance in chin and cheek in the teen population. More recently, we have been using this technique to correct facial disharmony in rhinoplasty patients.

METHODS/TECHNIQUE

Fat grafting was performed at the time of rhinoplasty in 22 patients (age, 15-19 years). Presurgical planning involved cephalometric and computer-enhanced photographic analysis of the face. Midface retrusion and underprojected mentum were treated. Deficient sites were treated with small aliquots of fat, which were injected into the supraperiosteal plane. The average amounts of fat grafting injected per region were 2 to 3 mL for the malar region and 8 to 10 mL for the chin and geniomandibular borders.

RESULTS/COMPLICATIONS

Twenty-two patients underwent augmentation of soft tissue and skeletal deficiencies. Analysis of postoperative results showed excellent outcomes with enhancement of facial profile and proportions. The mean follow-up was 3 years. The majority of patients reported high degree of satisfaction. No complications were observed.

CONCLUSIONS

The combination of rhinoplasty and autologous fat grafting offers very satisfactory esthetic outcomes and improvement of facial balance with minimal added time, cost, and risk.

Facial Fat Augmentation Finesse

Volume restoration with autologous fat augmentation has become a key technique in facial rejuvenation. It is highly versatile and useful as an independent operation or as an adjunct to rhytidectomy and blepharoplasty. The goal of this article and the accompanying videos is to provide a detailed step-by-step guide to achieving predictable and optimized surgical results.

Composite Face Lifting: The Combination of Stromal Enriched Lipograft With Face Minilift and Upper and Lower Blepharoplasty: A Review of 210 Cases

BACKGROUND

Face rejuvenation is increasingly challenging because patients request minimally invasive surgery; rapid surgical course and recovery; and fast, tangible, and long-term results. Rejuvenation of face often requires surgery to multiple areas, that is, the lateral face, the midface, the neck, and periorbital areas, in addition to the emerging procedures of face volumizing and biostimulation through fat injection. At our institution, a systematic approach comprising all of these procedures has been developed, with consistent results.

OBJECTIVE

The aim of this study was to describe the combination of blepharoplasty, minilift, and Stromal Enriched Lipograft (SEL) for thorough rejuvenation of face and neck regions.

METHODS

A prospective study was performed to evaluate outcomes and patient satisfaction with composite face lifting, comprising upper and lower blepharoplasties, minilift, and SEL in 210 patients between 2009 and 2018. Overall improvement after the procedure was rated on a scale of 1 to 5, where 1 is "poor," 2 is "fair," 3 is "good," 4 is "very good," and 5 is "excellent." The evaluation was expressed at 6 months postoperatively by the patient.

RESULTS

The amount of SEL transplanted varied from 22 to 56 mL per side (mean, 41). There were no cases of liponecrosis, infection of the grafted area, or pulmonary embolism. More than 85% of patients expressed a very good to excellent evaluation of the result obtained. No one expressed a degree of satisfaction less than good.

CONCLUSIONS

Composite face lifting seems as a safe and effective combined procedure for the rejuvenation of face. Face harmony not only depends on redraping tissues toward a more natural, tense, and young conformation, but also on restoring volumes and improving the quality of the redraped tissues. More research is necessary, but the preliminary encouraging impression is that the composite face lifting is capable of addressing all issues, the necessity of correcting laxity, filling volumes, and improving the quality of cutaneous tissues.

Forehead Fat Grafting: Asian Facial Contouring and Augmentation

BACKGROUND

Aesthetic facial contouring procedures, particularly forehead augmentation, continue to increase in popularity in the Asian population. However, there are very few reports in the literature specifically examining the long-term outcomes of forehead fat grafting. In the present study, the authors aimed to objectively evaluate the efficacy of autologous forehead fat grafting through evaluation of facial proportions and patient-reported outcomes.

METHODS

Patients who underwent autologous fat grafting for forehead contouring procedures between July of 2011 and June of 2017 were recruited for participation in the study. Patient demographic and clinical variables were collected preoperatively and postoperatively. Facial proportion analysis was collected and compared from preoperative and postoperative photographs. Satisfaction with outcome was assessed by the patient, the surgeon, and a layperson postoperatively. A related-samples Wilcoxon signed rank test was used for statistical analysis.

RESULTS

Postoperative outcomes were evaluated in a total of 24 patients who underwent forehead autologous fat-grafting procedures. The average postoperative follow-up was 8.1 months. There were no intraoperative or postoperative complications. More than 50 percent of the postoperative results were evaluated as "satisfactory" by all three groups (i.e., patient, surgeon, and layperson) in terms of aesthetic contouring. Average forehead projection increased 0.24 U (ratio of horizontal distance from midforehead plane to cornea plane/cornea diameter) after one round of fat grafting (p = 0.01). Seven patients (29.2 percent) required more than a single round of fat grafting to achieve optimal results.

CONCLUSIONS

Autologous fat grafting remains a viable option for forehead contouring and augmentation. The findings of this study demonstrate that the operation is effective and offers stable satisfactory results after long-term follow-up.

Application of Fat Grafting in Cosmetic Breast Surgery

The role of fat grafting to the breasts has evolved in the recent past, gaining several new applications within both reconstructive and aesthetic surgery. Initially used for reconstructive purposes to fill lumpectomy defects or to correct residual contour deformities after breast reconstruction, it has since made its way into cosmetic breast surgery and has grown to encompass a wide variety of new indications. Fat grafting in aesthetic breast surgery may be performed as a form of primary autologous breast augmentation or as an adjunct to implant-based breast augmentation to disguise implant edges. It may also be used to provide added volume after explant surgery or to provide improvements in breast contour alongside mastopexy techniques. In this article, we will review the current applications of fat grafting in aesthetic breast surgery and provide an up-to-date summary of its reported outcomes, safety, and complications.
