Hand Rejuvenation by Targeted Volume Restoration of the Dorsal Fat Compartments

Hand Rejuvenation with Customizable Hybrid Fillers: Premixed Calcium Hydroxyapatite and Hyaluronic Acid

INTRODUCTION

Hand aging is a prevalent concern characterized by the atrophy of local soft tissues and increased visibility of vessels and tendons. Hyaluronic acid (HA) and calcium hydroxyapatite (CaHA) are well-established treatments for addressing this issue. While hybrid filler containing HA and CaHA has been proposed for facial rejuvenation, studies investigating its efficacy for hand rejuvenation are lacking.

OBJECTIVE

This study aims to assess the safety and efficacy of a premixed hybrid filler containing calcium hydroxyapatite (CaHA) and hyaluronic acid (HA) for hand rejuvenation.

METHODS

A prospective, double-blind, controlled trial was conducted. The control arm (CA) received conventional subdermal treatment with CaHA at a 1:1 dilution. The intervention arm (IA) underwent hybrid treatment, consisting of CaHA at a 1:1 dilution combined with 1 ml of low-density HA. Evaluation was performed subjectively using the Global Aesthetic Improvement Scale (GAIS) and the Manchester Hand Grading System (MHGS), and objectively using cutometry, corneometry, and ultrasound.

RESULTS

Both the CA and the IA exhibited high rates of patient satisfaction and satisfaction as assessed by blinded evaluators. Although numerical superiority was observed in the IA, no statistical difference was found between the two groups. Significant improvements in hydration, elasticity, and skin thickness were observed in both arms, with no discernible difference between them. Greater ultrasound echogenicity was noted in the IA, which, as indicated by existing literature, may suggest enhanced biostimulation. No adverse effects were reported in either arm.

CONCLUSION

Premixed filler containing HA and CaHA for hand rejuvenation appears to be a safe and effective approach.

Fat transplant: Amazing growth and regeneration of cells and rebirth with the miracle of fat cells

BACKGROUNDS AND OBJECTIVE

During fat transplantation, adipose tissue is removed from the body and injected into different areas under the skin. The goal of this review article is to look into the efficacy and applicability of fat transplantation in regenerative medicine and rejuvenation, including Nanofat, Microfat, and Millifat.

METHODS

As a search strategy and study selection, we searched the PubMed and Medline databases until 2023 using related keywords (e.g., Nanofat, Microfat and Millifat, Regenerative Medicine, and Rejuvenation).

RESULTS

Autologous fat transplantation has no risk of an allergic reaction or rejection of the transplant by the individual. Autologous adipose tissue is considered an ideal filler for facial rejuvenation and is suggested as the most biocompatible and non-immunogenic skin filler. Adipose tissue transplant may have semi-permanent to permanent effects. According to recent reports, adipose tissues possess a high percentage of mature stem cells. The effect of regenerating adipose tissue and its intrinsic cells can be described as an obvious process. Variations in the sizes of adipose tissues can result in different results depending on the surgical site. Based on topographic assessment, graft fats are assigned depending on the anatomical locations and the size such as Millifat (2-2.5 mm), Microfat (1 mm), and Nanofat (500 μm or less).

CONCLUSION

Some characteristics of fat tissue increase its effectiveness, such as increasing stem cells, growth factors, cytokines, and compounds effective in repair, regeneration, and rejuvenation.

Revitalizing Hands: A Comprehensive Review of Anatomy and Treatment Options for Hand Rejuvenation

Dorsal hand rejuvenation is gaining popularity as a solitary procedure and adjunct to face and neck rejuvenation treatments. As the hands age, the skin loses elasticity and becomes more translucent, the veins, joints, and tendons appear more prominent, and the bones become more noticeable. These changes are due to intrinsic and extrinsic factors. Current treatment methods include the injection of dermal fillers and autologous fat grafting. Anatomic studies to ensure the successful implementation of rejuvenation procedures identified three separate fascial layers in the dorsum, from superficial to deep. More recent re-evaluations revealed a less distinct, inseparable, sponge-like fascial layer. All authors agree that the superficial dermal layer is probably the optimal location for the injection of volumizing materials because it is free of anatomical structures. Many methods for harvesting, preparing, and injecting fat grafts to the dorsum of the hand have been described in the past three decades. Both filler and fat-graft procedures are performed on an ambulatory basis under local anesthesia. Good results with low postoperative and long-term complication rates and high patient satisfaction have been reported.

Autologous Fat Grafting in the Upper Extremity: Defining New Indications

Autologous fat grafting is a commonly used technique in plastic surgery that can also be applied broadly in hand surgery. We present a case series to demonstrate the diverse indications for fat grafting in hand surgery.

Methods

We retrospectively reviewed cases of fat grafting in the upper extremity in 2020. Cases representing a unique application of fat grafting were identified. Patient data, including demographics, diagnoses, preoperative and postoperative assessments, complications, patient satisfaction, and surgical operative reports, were recorded.

Results

Five patients representing distinct indications for autologous fat grafting in the upper extremity were identified. Indications included hand rejuvenation (20.0%), burn/scar management (20.0%), tenolysis (20.0%), revision nerve decompression (20.0%), and carpometacarpal joint arthritis (20.0%). Average patient age was 60.4 years (range, 42-71). Average volume of fat injected was 15.2 ml (range, 1-37 ml). No major complications were noted (0.0%). All patients expressed satisfaction with their overall result with good functional outcomes (100%).

Conclusions

Autologous fat grafting can be applied broadly in hand surgery. Indications for fat grafting in hand surgery include hand rejuvenation, burn/scar management, tenolysis, revision nerve decompression, and thumb carpometacarpal arthritis. Hand surgeons can easily incorporate fat grafting into their daily practice. Current literature supports fat grafting as a viable technique in hand surgery with lower-level studies.

Autologous fat transfer for hand rejuvenation: systematic review on technique and outcome

Background

Age-related changes to the dorsum of the hand present as dyschromia, soft-tissue atrophy, and volume loss, resulting in wrinkles and prominent deep structures. Volume augmentation by means of autologous fat transfer (AFT) is one of the options to rejuvenate the hand; theoretically, autologous fat is the ideal filler because of durability and biocompatibility.

Objective

This systematic review aims to summarize and describe the current evidence on the technique, effectiveness, and safety of AFT in hand rejuvenation.

Methods

Three major databases, PubMed, Embase, and Web of Science, were systematically searched up to November 2020 for studies reporting on AFT and hand rejuvenation.

Results

A total of 10 articles were included, reporting on a total of 320 patients treated by AFT to improve the aesthetic appearance of the dorsum of the hand. Some degree of postoperative oedema was present in nearly all patients. Other complications were infection (0.67%), cysts/irregularities (1.3%), temporary dysesthesia (5.3%), and ecchymosis (7%). There were no major complications. Of all patients, 97.6% self-reported to be satisfied with the result.

Conclusions

Overall, by combining the current evidence, AFT is considered a promising and safe technique to rejuvenate the aging hand with very high patient satisfaction. Future research, using validated patient questionnaires, objective volumetric measurements, and longer follow-up, is needed to confirm these results.

Ultrasound Analyses of the Dorsal Hands for Volumetric Rejuvenation

BACKGROUND

Volumetric hand rejuvenation of the dorsal hands is increasingly applied for aged, skeletonized dorsal hand skin, with prominent veins, tendons, and joints due to volumetric loss of subcutaneous fat. However, the aging process of the fatty laminae remains unexplored.

OBJECTIVES

We aim to investigate the impact of aging and potential determinants on the fatty laminae to improve the therapeutic effect of volumetric injection.

METHODS

This cross-sectional study enrolled 105 Taiwanese participants aged ≥20 years, divided into five age groups per decade. Thicknesses of the dorsal superficial lamina (DSL), dorsal intermediate lamina (DIL), and dorsal deep lamina (DDL) were measured via ultrasonography by a single-blinded practitioner. The potential determining factors of the laminae thickness (age, sex, body mass index, and hand dominance) were analyzed.

RESULTS

The thicknesses of the three laminae decreased with aging, with the mean decrease in thickness from the 20s to >60 years in DSL, DIL, and DDL being 0.21 mm (30.0%), 1.38 mm (63.89%), and 0.31 mm (20.95%), respectively. DIL thickness decrease was the greatest and most significant since the 30s. Multiple linear regression analysis showed age as the only determinant for thicknesses of the 3 laminae (all P<0.001), whereas DIL was significantly thicker in men (P<0.001).

CONCLUSIONS

Volumetric fat loss was noted in the three fatty laminae of dorsal hands during aging; DIL has the greatest progressive fat loss since the 30s. Volumetric rejuvenation of the 3 laminae may result in the most esthetic appearance, especially in women.

Hand Rejuvenation: A Systematic Review of Techniques, Outcomes, and Complications

BACKGROUND

Hand rejuvenation is an increasingly popular cosmetic procedure for hand atrophy and aging. The objective of this study is to systematically evaluate the techniques, outcomes, and complications of surgical hand rejuvenation.

METHODS

A systematic review was undertaken using a computerized search. Publication descriptors, methodological details, techniques, outcomes, and complications were extracted. Articles were assessed using the MINORS and Cochrane instruments.

RESULTS

Thirty-one studies were included. Most studies were published in the last five years (51.6 percent) and were prospective case series (35.5 percent). The mean age of patients was 56 (range 21-82), while the mean sample size was 47 (range 10-220). The most commonly examined interventions were Radiesse (32.2 percent) and fat grafting (32.2 percent). Major complications were not observed in any study, while minor complications such as edema and pain were temporary. Injection techniques varied, however, the proximal to distal fanning technique and using a cannula was associated with a lower risk of complications. Both Radiesse and fat grafting had robust long-term esthetic outcomes.

CONCLUSIONS

Hand rejuvenation is a safe and efficacious surgical intervention to reduce dorsal hand atrophy. Further studies are needed to compare the long-term outcomes of common interventions.

Breast implant-associated anaplastic large cell lymphoma: clinical follow-up and analysis of sequential pathologic specimens of untreated patients shows persistent or progressive disease

Breast implant-associated anaplastic large cell lymphoma (ALCL) is a distinctive type of T-cell lymphoma that arises around textured-surface breast implants. In a subset of patients, this disease can involve surrounding tissues, spread to regional lymph nodes, and rarely metastasize to distant sites. The aim of this study was to assess sequential pathologic specimens from patients with breast implant-associated ALCL to better understand the natural history of early-stage disease. To achieve this goal, we searched our files for patients who had breast implant-associated ALCL and who had undergone earlier surgical intervention with assessment of biopsy or cytologic specimens. We then focused on the patient subset in whom a definitive diagnosis was not established, and patients did not receive current standard-of-care therapy at that time. We identified a study group of ten patients with breast implant-associated ALCL in whom pathologic specimens were collected 0.5 to 4 years before a definitive diagnosis was established. A comparison of these serial biopsy specimens showed persistent disease without change in pathologic stage in three patients, progression in five patients, and persistence versus progression in two patients. Eventually, six patients underwent implant removal with complete capsulectomy and four underwent partial capsulectomy. Seven patients also received chemotherapy because of invasive disease, three of whom also received radiation therapy, two brentuximab vedotin after chemotherapy failure, and one allogeneic stem cell transplant. Eight patients achieved complete remission and two had partial remission after definitive therapy. At time of last follow-up, six patients were alive without disease, one had evidence of disease, one died of disease, and two patients died of unrelated cancers. In summary, this analysis of sequential specimens from patients with breast implant-associated ALCL suggests these neoplasms persist or progress over time if not treated with standard-of-care therapy.

Dorsal Hand Rejuvenation: A Systematic Review of the Literature

BACKGROUND

Dorsal hand appearance undergoes changes with aging. Grading systems have been designed to provide numerical scores to dorsal hand appearance. Various modalities have been utilized to improve the aesthetic appearance and rejuvenate the dorsal hand.

METHODS

The MEDLINE database was searched for articles investigating dorsal hand rejuvenation. Studies were grouped by method including fat grafting, injectable filler, laser/light-based treatments and miscellaneous treatments. Treatment protocols and outcomes were compiled along with patient information and complications.

RESULTS

Forty-six articles were identified for inclusion. This included 9 studies of fat grafting procedures, 20 studies of injectable filler, 10 studies of laser/light-based treatments and 7 miscellaneous. Most studies showed overall good results with high patient satisfaction. Satisfaction rates were lower in laser/light-based treatments compared with the other modalities. The average patient age for included studies ranged from 41.5 to 69. Across all studies, 96.8% of patients were female and 3.2% male.

CONCLUSIONS

Procedures for dorsal hand rejuvenation in the literature include procedures to address volume atrophy and superficial wrinkling. These procedures are overall safe with most studies reporting no complications or only mild adverse events. With high satisfaction rates and anecdotal reports of increasing patient interest, these procedures represent a developing area in aesthetic surgery likely to continue increasing in popularity.

Autologous Fat Grafting in Hand Surgery

Autologous fat grafting is commonly used in plastic and reconstructive surgery, but its indications are less well known in the hand surgery literature. Autologous fat grafting is frequently used for its anti-inflammatory, proangiogenic, and regenerative properties, which can be useful in treating the hand and upper extremity. We present a summary of the current literature on autologous fat grafting in the hand and upper extremity and discuss the applications, outcomes, techniques, safety, and level of evidence.

A Review of Hand Feminization and Masculinization Techniques in Gender Affirming Therapy

INTRODUCTION

Anatomical characteristics that are incongruent with an individual's gender identity can cause significant gender dysphoria. Hands exhibit prominent dimorphic sexual features, but despite their visibility, there are limited studies examining gender affirming procedures for the hands. This review is intended to cover the anatomical features that define masculine and feminine hands, the surgical and non-surgical approaches for feminization and masculinization of the hand, and to adapt established aesthetic hand techniques for gender affirming care.

METHODS

The authors performed a comprehensive database search of PubMed, Embase OVID and SCOPUS to identify articles on the characterization of masculine or feminine hands, hand treatments related to gender affirmation, and articles related to techniques for hand masculinization and feminization in the non-transgender population.

RESULTS

From 656 possibly relevant articles, 42 met the inclusion criteria for the current literature search. There is currently no medical literature specifically exploring the surgical or non-surgical options for hand gender affirmation. The available techniques for gender affirming procedures discussed in this paper are appropriated from those more commonly used for hand rejuvenation.

CONCLUSION

There is a dearth of literature addressing the options for transgender individuals seeking gender affirming procedures of the hand. Though established procedures used for hand rejuvenation may be utilized in gender affirming care, further study is required to determine relative salience of various hand features to gender dysphoria in transgender patients of various identities, as well as development of novel techniques to meet these needs.

Efficacy and Safety of 2 Injection Techniques for Hand Biostimulatory Treatment With Diluted Calcium Hydroxylapatite

BACKGROUND

Calcium hydroxylapatite (CaHA) is effective for dorsal hand rejuvenation. Higher dilutions are used for biostimulation with fewer side effects.

OBJECTIVE

To evaluate the efficacy and safety of 2 techniques of diluted CaHA injection for dorsal hand treatment.

METHODS

A prospective, evaluator-blinded study was performed to compare (side-to-side) techniques for treating the dorsum of the hands with diluted CaHA: deep fat lamina or subdermal injection. Fifteen women with aging grades between 1 and 3 on the MHGS (Merz hand grading scale) were enrolled and followed up for 24 weeks. The outcomes were a histological analysis of collagen, skin viscoelasticity, high-frequency ultrasound parameters, MHGS score, and the global aesthetic improvement scale (GAIS) score.

RESULTS

Improvement in the MHGS and GAIS scores (p < .01) was observed, with no difference between techniques (p > .05). Skin viscoelasticity measures and ultrasonography for dermal parameters improved for both treatments (p < .01). The mean total collagen density increased from the baseline for both techniques (p < .01). Pain during the procedure as well as adverse effects within the follow-up did not differ between treatments (p > .4). The overall satisfaction was 12% greater for the subdermal technique (p < .05).

CONCLUSION

Diluted CaHA improves the skin quality of aging hands with a safe profile, without substantial differences between the techniques.

Fat Grafting for Hand Rejuvenation

The hands are one of the most visible parts of the body, and prominent dorsal veins and extensor tendons are the most readily recognized signs of the aging process. Fat grafting has been demonstrated to be a safe and effective method of hand rejuvenation by restoration of subcutaneous fat. Despite some variability in the technical approach, fat grafting techniques are consistent in their use of low-pressure injection with standard cannula sizes, small aliquots of graft, and a total volume of graft greater than or equal to 15 mL per hand. While distribution of the fat is an area of debate and a topic of active research, published studies have shown high patient satisfaction rates, suggesting that perhaps the restoration of volume alone is paramount. In this article, we will review the applications of fat grafting to the hand, focusing primarily on its role in hand rejuvenation.

A randomized study showing improved skin quality and aesthetic appearance of dorsal hands after hyaluronic acid gel treatment in a Chinese population

BACKGROUND

Patients are increasingly aware of the aesthetic appearance of aging hands.

AIMS

To evaluate efficacy and safety of a hyaluronic acid gel for improving skin quality in aged skin of the dorsal hand.

METHODS

This was a 15-month randomized, multi-center, evaluator-blinded, split-hand, no treatment-controlled study. Three treatments with hyaluronic acid gel were administered in the same hand in adult Chinese subjects with grade 2 or 3 (mild or moderate aging) on the Hand Grading Scale (HGS). The primary objective was to evaluate the difference at 3 months between treated and untreated hands, based on the blinded evaluator's HGS assessment. Secondary assessments included the Global Aesthetic Improvement Scale (GAIS), biophysical measurements (skin elasticity, skin roughness and hydration), and subject satisfaction. Safety was evaluated by incidence of adverse events.

RESULTS

A total of 100 subjects were enrolled. Clinically relevant differences in HGS favored HA gel (P < .0001). At 15 months, 87%-96% of treated hands were still improved according to GAIS (per evaluator and subject, respectively). Objective measures of skin quality improved, confirmed by evaluators and highly satisfied subjects. Treatment was well tolerated.

CONCLUSIONS

Hyaluronic acid treatment improved skin quality and reduced the aging appearance of the hand, with high subject satisfaction.

Long-term Outcomes of Temporal Hollowing Augmentation by Targeted Volume Restoration of Fat Compartments in Chinese Adults

Importance

Previous anatomical and clinical studies have suggested that targeted restoration of the volume and distribution of fat compartments using appropriate cannula entry sites and injection planes is an excellent fat-grafting technique for facial contouring and hand rejuvenation.

Objective

To perform subjective and objective evaluations of the safe and effective profile of the targeted fat-grafting technique for temporal hollowing augmentation.

Design, Setting, and Participations

In a retrospective cohort study, a total of 96 consecutive patients with temporal hollowing were treated at the Department of Plastic and Reconstructive Surgery, Shanghai Ninth People's Hospital, Shanghai, China, with the targeted fat-grafting technique from January 1, 2009, to January 1, 2017.

Main Outcomes and Measures

The safety and efficacy profile of this technique was evaluated by the following methods: (1) a quantitative measurement of fat-graft survival and temporal augmentation rates by using 3-dimensional laser scanning, (2) a subjective assessment using a satisfaction survey and the Hollowness Severity Rating Scale (grades range from 0-3, with higher grades representing more hollowness), and (3) the complication rate.

Results

Of the 96 study patients, 94 (97.9%) were women and the mean (SD) age was 34.4 (7.4) years. Of the 142 autologous fat-grafting procedures performed, the mean (SD) total follow-up time was 16.3 (3.2) months, with a mean (SD) of 1.5 (0.7) procedures performed. The mean (SD) baseline volume requirement per temple for each patient was 12.8 (4.8) mL, and the total volume of the fat graft per temple was 17.8 (7.5) mL. Quantitative analysis revealed that the mean (SD) total augmentation volume per temple was 11.7 (3.0) mL, the total survival rate of the fat grafts was 65.7% (12.6%), and total augmentation rate of hollowness was 91.4% (23.4%). Subjective analysis revealed that all patients showed an improved appearance after fat grafting, and 142 temples (74.0%) exhibited clinical improvement by more than 2 grades. In all, 88 patients (91.7%) were satisfied with the outcomes, with a low complication rate reported.

Conclusions and Relevance

The targeted fat-grafting technique allows the transplant of fat tissue into 4 separate fat compartments in a double-plane manner through a unique cannula entry site that avoids severe neurovascular injury. The long-term results demonstrate that this technique is an effective, reproducible, and safe approach for temporal hollowing augmentation.

A Preliminary Clinical Trial Comparing Split Treatments to the Face and Hand With Autologous Fat Grafting and Platelet-Rich Plasma (PRP): A 3D, IRB-Approved Study

BACKGROUND

Numerous methodologies have been suggested to enhance fat graft survival, but few long-term studies are available.

OBJECTIVES

The authors of this institutional review board-approved study investigated the safety and efficacy of utilizing platelet-rich plasma (PRP).

METHODS

Each of 10 patients received equal volumes of syringe-harvested, centrifuged fat to opposing midfaces with a lateral submuscular aponeurotic system-plication or no face lift and hands that were combined with equal volumes of either concentrated PRP or normal saline. Comparable assessments of fat retention/baseline values by 3D Vectra Analysis, VISIA, and Cortex facial skin analyses were performed. Clinical results were judged on a visual analogue scale.

RESULTS

The average percent change in mean volume assessments at the fat/PRP sites from baseline values, as profiled by 3D Vectra Analysis, demonstrated a higher, but statistically nonsignificant value over 1 year than the percent value changes at the fat/normal saline sites in the opposing face or hand. Three independent evaluators were able to assess volume restorations to the malar fat pad, naso-jugal groove, and nasolabial fold as well as to intermetacarpal hollowness with reduction of visible veins and tendons in the anterior midface and hands with both treatments. No adverse events were observed over the year-long study. Perioperative edema, erythema, bruising, and tenderness lasted up to 1 to 2 weeks at most.

CONCLUSIONS

Autologous fat grafting continues to be a safe and effective adjunct in facial and hand aesthetic surgery. This study will require more patients and longer follow-up periods to determine whether PRP has a potential role to increase fat graft retention in aesthetic patients.

Characteristics and Treatment of Advanced Breast Implant-Associated Anaplastic Large Cell Lymphoma

BACKGROUND

Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) most commonly follows an indolent course; however, a subset of patients display more advanced disease marked by recurrent and disseminated growth refractory to treatment. This study evaluated outcomes of advanced disease, specifically bilateral disease, lymph node involvement, organ metastasis, and/or disease-related death.

METHODS

Published cases of BIA-ALCL from 1997 to 2018 and unpublished cases at the authors' institution were retrospectively reviewed, and patients with advanced disease were selected. Treatment and outcomes were compared against a control of BIA-ALCL subjects without advanced disease.

RESULTS

Thirty-nine patients with advanced BIA-ALCL were identified who had bilateral disease (n = 7), lymph node and organ metastasis (stage IIB-IV, n = 24), and disease-related death (n = 8). Sixty-five patients were included in a comparison control group (stage 1A-1C). Treatment types for advanced disease patients were complete surgery, n = 16 (55.2%); limited surgery, n = 19 (65.5%); chemotherapy, n = 26 (89.7%); salvage chemotherapy, n = 11 (37.9%); radiation, n = 15 (51.7%); and autologous stem cell transplant, n = 6 (20.7%). The rates of complete remission for the bilateral and lymphadenopathy groups were 4 of 7 (57%, P < 0.001) and 16 of 24 (67%, P = 0.128), respectively. Compared with the control group, advanced disease patients had significantly longer time from diagnosis to definitive surgery (21 versus 8 months, P = 0.039) and a lower rate of complete surgery (59% versus 88%, P = 0.004).

CONCLUSIONS

Advanced disease BIA-ALCL may be a consequence of a delay or suboptimal treatment of BIA-ALCL. Optimal adjuvant chemotherapy and indications for radiation for BIA-ALCL patients with advanced features are not yet clearly defined. Advanced disease is the end of the spectrum of cancer stages, and these patients substantiate the World Health Organization classification of BIA-ALCL as a lymphoma rather than benign or lymphoproliferative.

Calcium Hydroxyapatite (CaHA) Indication for Hand Rejuvenation

The recent approval in 2015 of Radiesse for injection into the hand by the FDA has spurred an increase in interest among patients and clinicians in nonsurgical hand rejuvenation using fillers. Application of the same techniques used to treat the face to the dorsum of the hands does not account for the unique nature of the skin and underlying anatomy, and can lead to suboptimal outcomes and an increased risk of adverse events such as the formation of nodules. Here, the authors discuss dilution strategies and injection techniques for hand rejuvenation using Radiesse for optimal patient safety and aesthetic outcomes.
