ABSTRACT

BACKGROUND: Understanding the differences in soft tissue filler rheology and how these properties can impact clinical results is a fundamental concepts for any injector. This study aimed to assess the tissue integration characteristics of hyaluronic acid (HA) fillers manufactured with different technologies (Non-Animal Stabilized HA [HA-N] or Optimal Balance Technology [HA-O]) using ultra-high-frequency ultrasound. METHODS: Twelve female participants with mild-to-moderate midface volume loss and temporal hollowing were enrolled and treated with HA-N and/or HA-O. Participants were seen at five visits (screening/baseline [treatment], and Weeks 1 [optional touch-up], 4, 6, and 8 [follow-up visits]). Ultrasound was used to evaluate the degree of product integration. RESULTS: On ultrasound, HA-N presented with distinct borders, minimal tissue integration, and a capacity to displace tissues. Conversely, HA-O tended to spread horizontally within the same tissue plane and integrated within tissues. The volumizing capacity of the HA-O fillers was dependent on particle size. CONCLUSION: HA-N is suited for deep injections in areas such as the upper lateral cheek and under the muscle of the temporal region when a lifting effect is desired; HA-O is best suited for subcutaneous injections, in areas of dynamic movement or for patients with thin skin; and can be injected subcutaneously or supraperiosteally when a volumizing effect is desired.

ABSTRACT

BACKGROUND: A hyaluronic acid (HA) filler intended for non-surgical improvement of chin appearance should ideally be of high strength/firmness (high G') to allow for deep injections on the bone. HASHA (Restylane Shaype) is a new hyaluronic acid (HA) injectable with high G' and high HA concentration (25 mg/mL), engineered by the new NASHA-HD (High Definition) technology. HASHA is suitable to be placed periosteally, aiming to mimic the natural shape of the bony chin. This pivotal clinical investigation evaluated effectiveness and safety of HASHA for augmentation and correction of chin retrusion.  Methods: Subjects 18 years or older with mild or moderate chin retrusion by the Galderma Chin Retrusion Scale (GCRS), were randomized 3:1 to HASHA (n=103) or no treatment (n=37). Assessments included GCRS (blinded evaluator), aesthetic improvement (Global Aesthetic Improvement Scale [GAIS]), subject satisfaction, and safety.  Results: GCRS responder rate (1-grade or greater improvement from baseline) was significantly higher for HASHA (83.3%) versus controls (10.8%) at month 3 (P<0.001) and maintained through month 12 (P<0.001). Aesthetic improvement was high throughout the study in the HASHA group, according to investigators (97% or greater) and subjects (89% or greater). Overall, subject satisfaction was high at month 3 and maintained at month 12. Product- or injection-related adverse events were mostly mild or moderate and transient. No product- or injection-related serious adverse events were reported. CONCLUSIONS: HASHA, a new NASHA-HD injectable with extra strength/firmness, was safe and effective for chin augmentation and correction of chin retrusion, with high aesthetic improvement and subject satisfaction throughout 12 months.

ABSTRACT

BACKGROUND: Contour deficits of the jawline are an area of concern for many aesthetic patients. While the use of hyaluronic acid (HA) for jawline enhancement has been described previously, comparative investigations of HA fillers manufactured with different technologies are limited. Therefore, the aim of the current investigation was to evaluate the safety and efficacy of Restylane Lyft (HA-L) and Restylane Defyne (HA-D) for contouring of the jawline. METHODS: This prospective clinical trial enrolled forty (40) participants. Twenty (20) participants with thin skin were treated with HA-D, and twenty (20) participants with thick skin were treated with HA-L. Visits occurred at Screening/Baseline (treatment), Week 2 (touch-up), and Months 1, 3, and 6. At each visit, a blinded evaluator rated 3-dimensional participant imagery according to the Jawline Volume Loss Scale and participants completed the Jawline Subject Satisfaction Scale. Frequency of treatment-emergent adverse events was collected via participant diaries, and product integration characteristics were evaluated via ultrasound. RESULTS: Chi-square tests of independence revealed statistically significant improvements in severities of jawline volume loss, which were maximal at Month 1 (100%) and maintained until Month 6 (82.05%). At Month 1, 92.10% of participants reported being satisfied with overall treatment effects. Adverse events were expected per the product monographs and did not vary per group. On ultrasound, HA-L displayed targeted product integration and HA-D displayed diffuse product integration. CONCLUSIONS: Results support the use of HA-L and HA-D for the contouring of the jawline with each product capable of providing distinct advantages depending on patient attributes (e.g., skin thickness, underlying bone structure, desired outcomes). LEVEL III: Evidence obtained from well-designed cohort or case-control analytic studies. LEVEL OF EVIDENCE III: This journal requires that authors assign a level of evidence to each article.

ABSTRACT

BACKGROUND: Addressing neck contouring with surgical and nonsurgical aesthetic procedures includes understanding the origin of platysmal banding. A theory was postulated to explain this phenomenon by isometric vs isotonic muscular contraction patterns. However, no scientific proof had been provided to date for its correctness. OBJECTIVES: The aim of this study was to confirm the correctness of the platysmal banding theory based on isometric vs isotonic muscular contractions. METHODS: Eighty platysma muscles from 40 volunteers (15 males and 25 females) were investigated (mean age 41.8; SD 15.2 years; mean BMI of 22.2; SD 2.3 kg/m2). Real-time ultrasound imaging was utilized to measure the increase in local muscle thickness inside and outside of a platysmal band as well as platysma mobility. RESULTS: Within a platysmal band, the local thickness of the muscle increases during muscular contractions by 0.33 mm (37.9%; P < .001). Outside of a platysmal band the thickness of the platysma muscle decreased by 0.13 mm (20.3%; P < .001). It was identified that within a platysmal band no gliding was detectable, whereas outside of a band an average muscle gliding of 2.76 mm was observed. CONCLUSIONS: The results confirm the correctness of the isometric vs isotonic platysma muscle contraction pattern theory: isotonic muscle contraction (gliding without increase in tension and therefore in muscle thickness) vs isometric muscle contraction (no gliding but increase in tension and therefore in muscle thickness). These 2 types of contraction patterns occur within the platysma simultaneously and are an indicator for zones of adhesion in the neck to guide surgical and nonsurgical aesthetic procedures.

ABSTRACT

BACKGROUND: In 2022, the US experienced a significant increase in demand for minimally invasive aesthetic procedures, underscoring its rising acceptance amid an unregulated educational environment for practitioners. The absence of standardized educational pathways and quality control in aesthetic medicine, primarily provided by nonacademic institutions, highlights a critical need for establishing educational standards to ensure practitioner competence and patient safety. OBJECTIVES: The aim of this study was to identify levels of competency for the aesthetic practitioner and necessary achievement milestones during the educational path from novice to expert injector. METHODS: A total of n = 386 international study participants responded to an online questionnaire regarding their experience in aesthetic medicine practice. The questionnaire comprised 58 questions focusing on professional data, the perceived difficulty of injection, and risk for the occurrence of adverse events for specific facial regions in soft tissue filler and toxin injections. RESULTS: Regardless of medical specialty and experience level, averages of 3.85 (1.8) years, 786.4 (2628) filler injections and 549.9 (1543) toxin injections were estimated to progress from novice to advanced injector, while averages of 6.10 (3.7) years, 1842.2 (4793) filler injections, and 1308.5 (3363) toxin injections were estimated to advance from advanced to expert injector. The nose and the perioral region have been ranked as the facial regions where it is most difficult to achieve a perfect aesthetic outcome and with the greatest risk for the occurrence of adverse events for filler and toxin injections, respectively. CONCLUSIONS: In this study we establish an educational framework in aesthetic medicine by defining the progression from novice to competent and expert injector levels, suggesting 4 years of practice and over 790 filler and 550 neuromodulator injections for competence, and at least 6 years with 1840 filler and 1310 neuromodulator injections for expertise. We also identify critical facial regions for targeted treatments by different expertise levels.

ABSTRACT

BACKGROUND: Hyaluronic acid (HA) fillers may be manufactured to have distinctive physical properties that optimize their use for specific indications. Fillers manufactured with large gel calibration (particle size; HA-V) may be particularly suitable for volumizing large surface areas such as the temporal hollows. OBJECTIVE: To investigate the safety and effectiveness of HA-V for the treatment of temporal hollows. MATERIALS AND METHODS: A prospective, open-label, single-cohort, clinical trial was conducted. Twenty-six women who presented with bilateral temporal hollows at baseline were recruited. All subjects received treatment with HA-V and were observed at 4 to 5 in-person visits over 16 weeks. Subjective and objective measures of safety and efficacy parameters were collected through 2- and 3-dimensional imagery, questionnaires/scales (i.e., subject satisfaction, global aesthetic improvement, temporal hollowing severity), and adverse event diaries. RESULTS: To achieve optimal correction, the investigator used an average of 1.70 syringes per subject, per side. All treatments were performed using a bolus injection technique to place the product on the periosteum (bone) of the temporal region. Following optimal correction, all subjects (100%) displayed improvement in their global aesthetic appearance, and 25 of 26 subjects (96.15%) displayed ≥1 grade improvement on the temporal volume scale. Subject satisfaction was high, with 91.3% of subjects being satisfied with the appearance of their temporal regions following optimal correction. CONCLUSION: In this pivotal trial, HA-V was evidenced to have an excellent safety profile and proven efficacy up to 16 weeks, making it a suitable HA filler for volumization of the temporal region.

ABSTRACT

BACKGROUND: The measured intraarterial volume of cadaveric ophthalmic arteries was utilized for safety recommendations during facial soft tissue filler injections. However, its clinical practicability and model applicability have become questionable. OBJECTIVES: To measure the volume of the ophthalmic artery in living individuals by utilizing computed tomography (CT) imaging technology. METHODS: A total of 40 Chinese patients (23 males, 17 females) were included in this study with a mean age of 61.0 (14.2) years and a mean body mass index of 23.7 (3.3) kg/m2. Patients were investigated with CT imaging technology to evaluate the length, diameter, and volume of the bilateral ophthalmic arteries as well as the length of the bony orbits, resulting in a total of 80 investigated ophthalmic arteries and orbits. RESULTS: Independent of gender, the average length of the ophthalmic artery was 80.6 (18.7) mm, the calculated volume of the ophthalmic artery was 0.16 (0.05) mL and the minimal and maximal internal diameter of the ophthalmic artery were 0.50 (0.05) mm and 1.06 (0.1) mm, respectively. CONCLUSIONS: Based on the results obtained from the investigation of 80 ophthalmic arteries it must be concluded that current safety recommendations should be reevaluated. The volume of the ophthalmic artery appears to be 0.2 mL rather than 0.1 mL as previously reported. In addition, it appears impractical to limit the volume of soft tissue filler bolus injections to 0.1 mL due to the aesthetic requirements of each individual patient and treatment plan.

ABSTRACT

BACKGROUND: There is a significant emphasis on minimally invasive whole-body rejuvenation throughout the world. Recently, gluteal aesthetics have become an increasingly common patient concern. Although the application of poly-L-lactic acid (PLLA) to the face is already well known, there are relatively fewer publications on its use in other corporeal regions. This study aims to extend previous findings by evaluating the efficacy and safety of PLLA in the treatment of contour (including lifting) deformities of the buttock region. METHODS: This was a prospective, multicenter (3 sites), single cohort, open-label clinical trial. Thirty female subjects were treated with PLLA in the bilateral buttocks, with three treatment sessions, each spaced one month apart and followed for six months after completion of the treatment regimen. At each visit, various safety and clinical efficacy parameters were collected, these included: Global Assessment of Improvement Scale (GAIS), subject satisfaction, skin hydration, elasticity, scaliness, roughness, and 3-dimensional imagery. RESULTS: Six months following the last treatment, 84.00% of patients were rated as having “improved” or more on the physician assessed GAIS, accompanied by a 96.00% patient satisfaction rate. Approximately three vials of PLLA, per buttock and treatment were used. There were no serious adverse events throughout the duration of the trial, nor adverse events related to the investigational device. The most common subject-reported adverse events included pain during treatment (Mean: 70.97%) and bruising (Mean: 28.80%). Objective improvements were persistent after treatment in measurements of skin elasticity (improved 63.5% - 82.5% from weeks 16-32), hydration (increased ~11 Corneometer® units by week 16), roughness (decreased 36.95% at week 32), and scaliness (desquamation; decreased 60.41% at week 32). CONCLUSIONS: PLLA is safe and effective for the indication of buttock contouring and improving parameters of skin health. PLLA can provide long-lasting effects with a high level of patient and physician satisfaction. J Drugs Dermatol. 2022;21(3):304-308. doi:10.36849/JDD.5924.

ABSTRACT

Restylane® Lidocaine is one of the most widely used hyaluronic acid (HA) fillers to replace lost or displaced volume during tear trough correction. Patient goals for tear trough correction include looking less tired or removing dark circles and this may be achieved by administering HA filler into the infraorbital region to correct the lower eyelid relative to the volume deficit, thereby smoothing the transition from the lower eyelid to the cheek. To achieve patient satisfaction and consistent results with Restylane, optimal application is essential; however, clinical guidance based on experience is limited. This paper reflects the recommendations of an interdisciplinary expert panel for the use of Restylane in correcting tear trough deformity, including patient selection, dosing, injection technique, and post-treatment care. Recommendations were discussed and agreed as a consensus, according to cross-sectional expertise and clinical experience. J Drugs Dermatol. 2022;21(4):387-392. doi:10.36849/JDD.6597.

ABSTRACT

BACKGROUND: Periorbital deformities can be corrected utilizing hyaluronic acid injections. However, previous studies have not evaluated the effect of utilizing different injection techniques (eg, a needle vs cannula) on efficacy and safety. OBJECTIVES: The authors sought to investigate the efficacy and safety of HA for the correction of periorbital deformities when utilizing either needle or cannula-assisted injections. METHODS: This was a prospective, randomized-controlled (with crossover), evaluator-blinded study. Forty-two patients with a mean age of 44.82 ± 11.62 years were recruited. Patients underwent 2 treatment sessions, spaced 2 weeks apart, and attended 1 follow-up visit at Week 4, following the last treatment. Patients were randomized in a 3:3:1 ratio, whereby 18 patients received injections by needle, 18 received injections by cannula, and 6 were randomized to act as their own control at baseline. Those in the control group were randomized (n = 3) to needle or cannula injections at Week 4 and proceeded with the same visit schedule as those treated at baseline. At Weeks 2 and 4 posttreatment, patient satisfaction was evaluated and information on adverse effects was collected. A blinded reviewer assessed patient imagery utilizing standardized efficacy scales. RESULTS: Chi-square tests did not reveal any associations between treatment group and efficacy, safety, or patient satisfaction scores (P ≥ 0.05). Adverse effects reported in patient diaries were mild to moderate in nature and expected. CONCLUSIONS: For the treatment of infraorbital deformities, hyaluronic acid injections performed utilizing either a cannula or needle result in similarly high efficacy and safety ratios.

ABSTRACT

BACKGROUND: HARK is an FDA-approved flexible filler designed for lips. OBJECTIVE: To quantitatively evaluate subject outcomes by measuring the change in lip texture, color (redness), lip fullness, and lip and perioral surface stretch (dynamic strain) after treatment. METHODS AND MATERIALS: In this 8-week open-label, Phase IV multicenter study, subjects were treated with HARK in the lips and HARR and/or HARD in perioral wrinkles and folds as add-on treatment. Assessments included 2D photographic analyses of lip texture and color, and 3D photographic assessments of lip enhancement and dynamic strain. RESULTS: HARK significantly improved lip texture (p ≤ .002), lip redness (p < .001), and added fullness to the lips (lip enhancement measurements; p < .001), at Week 8 after treatment. In addition, lower lip wrinkles were significantly reduced (p = .007) and there was a reduction in upper lip wrinkles (not statistically significant). Surface stretch (dynamic strain) in the lip and perioral region was significantly increased after treatment (p < .001). CONCLUSION: This analysis provides an objective measure of the beneficial effects of flexible hyaluronic acid fillers in lip augmentation and perioral enhancement and demonstrates a significantly improved lip texture, red color, and fullness. A significant increase in surface stretch (dynamic strain) is indicative of tissue expansion and improvement in lip smoothness.

ABSTRACT

BACKGROUND: Since lips have a significant role in facial aesthetic perception, lip augmentation is an increasingly popular aesthetic procedure. OBJECTIVE: To evaluate aesthetic improvement and facial dynamics with hyaluronic acid (HA) fillers in the lips and perioral region at 8 weeks after the last treatment compared to pre-treatment. METHODS AND MATERIALS: In this open-label study, all subjects received HARK in the lips, and an additional group also received HARR and/or HARD in nasolabial folds (NLFs) and marionette lines (MLs). Assessments included aesthetic improvement, naturalness of facial expressions, perception of age, and lip texture. RESULTS: Nineteen subjects received HARK only; 40 received HARK and HARR and/or HARD. The primary objective was met. All subjects experienced aesthetic improvement in lip fullness at week 8. The investigators also reported aesthetic improvement in all subjects. For the majority of subjects, aesthetic improvement was associated with maintenance of natural and youthful facial expressions, and improved lip texture. Most treatment-emergent adverse events were mild; none were serious. CONCLUSION: HARK is a well-tolerated and effective treatment for enhancing lip fullness, maintaining naturalness and youthfulness of facial expressions, and smoothing lip texture, whether used alone or in combination with HARR/ HARD in the NLFs and/or MLs.

ABSTRACT

BACKGROUND: The temple has been identified as one of the most compelling facial regions in which to seek aesthetic improvement-both locally and in the entire face-when injecting soft tissue fillers. OBJECTIVE: The objective of this study is to identify influences of age, gender, and body mass index (BMI) on temporal parameters to better understand clinical observations and to identify optimal treatment strategies for treating temporal hollowing. METHODS: The sample consisted of 28 male and 30 female individuals with a median age of 53 (34) years and a median BMI of 27.00 (6.94) kg/m2. The surface area of temporal skin, the surface area of temporal bones, and the temporal soft tissue volume were measured utilizing postprocessed computed tomography (CT) images via the Hausdorff minimal distance algorithm. Differences between the investigated participants related to age, BMI, and gender were calculated. RESULTS: Median skin surface area was greater in males compared with females 5,100.5 (708) mm2 versus 4,208.5 (893) mm2 (p < 0.001) as was the median bone surface area 5,329 (690) mm2 versus 4,477 (888) mm2 (p < 0.001). Males had on average 11.04 mL greater temporal soft tissue volume compared with age and BMI-matched females with p < 0.001. Comparing the volume between premenopausal versus postmenopausal females, the median temporal soft tissue volume was 46.63 mL (11.94) versus 40.32 mL (5.69) (p = 0.014). CONCLUSION: The results of this cross-sectional CT imaging study confirmed previous clinical and anatomical observations and added numerical evidence to those observations for a better clinical integration of the data.

ABSTRACT

BACKGROUND: Paradoxical adipose hyperplasia (PAH) is a rare, moderate-to-severe adverse event associated with cryolipolysis (CoolSculpting, CS). OBJECTIVES: The aim of this study was to describe the incidence, diagnosis, and treatment of PAH occurring after CS for nonsurgical fat reduction. METHODS: A multicenter evaluation of all patients who underwent CS treatment between January 2015 and December 2019 at 8 Canadian medical centers was conducted. Data abstracted included symptoms, management strategy, outcome, operator characteristics, device characteristics, patient characteristics, body region, and CS treatment details. Incidence of PAH was calculated based on the number of treatment cycles. RESULTS: Our findings revealed incidence rates between 0.05% and 0.39%, which are slightly higher than the manufacturer's quoted rate of 0.025% (1 per 4000 cycles). Incidence rates at all sites were dramatically reduced by over 75% with the implementation of newer models of CS units. Of patients who developed PAH, 55% were male and 77.8% were of European ethnic origin. The majority of cases (76.9%) were associated with older models of CS units. CONCLUSIONS: Development of PAH may be related to a combination of factors, including older models of CS units and applicators, as well as individual characteristics that predispose certain patients.

ABSTRACT

BACKGROUND: The effect of hand dominance on the skin topography and parameters associated with skin health and aging is unknown. METHODS: Healthy adult volunteers were recruited. The following four strata were enrolled: Group 1: male, right handed; Group 2: male, left handed; Group 3: female, right handed; and Group 4: female, left handed. The differences between groups on their surface evaluation of living skin (SELS) parameters were evaluated. These variables included (a) roughness (SER); (b) smoothness (SESM); (c) scaliness (SESC); and (d) wrinkles (SEW). RESULTS: A total of twenty subjects were recruited, with five in each stratum. Significant differences between groups were found for SESC [F(7,31) = 2.742, P = .024, partial eta squared = 0.382] and SEW [F(7,31) = 3.705, P = .005, partial eta squared = 0.456]. An evaluation of the descriptive statistics revealed that males had a higher mean SESC value than females and a lower mean SEW value. Moreover, the dominant hand of both sexes had a higher mean SEW value than non-dominant hands. CONCLUSIONS: Given the evidence of sex and handedness differences in wrinkle genesis and desquamation severity, these factors should be considered in the dermatological treatment and counseling of patients.

ABSTRACT

BACKGROUND: Glabellar soft tissue filler injections have been shown to be associated with a high risk of causing injection-related visual compromise. OBJECTIVES: The aim of this study was to identify the course of the superficial branch of the supratrochlear and of the deep branch of the supraorbital artery in relation to the ipsilateral vertical glabellar line and to test whether an artery is located deep to this line. METHODS: Forty-one healthy volunteers with a mean age of 26.17 [9.6] years and a mean BMI of 23.09 [2.3] kg/m2 were analyzed. Ultrasound imaging was applied to measure the diameters, distance from skin surface, distance between the midline, distance between vertical glabella lines, and the cutaneous projection of the supratrochlear/supraorbital arteries at rest and upon frowning. RESULTS: The mean distance between the superficial branch of the supratrochlear artery and the ipsilateral vertical glabellar line was 10.59 [4.0] mm in males and 8.21 [4.0] mm in females, whereas it was 22.38 [5.5] mm for the supraorbital artery in males and 20.73 [5.6] mm in females. Upon frowning, a medial shift in supratrochlear arterial position of 1.63 mm in males and 1.84 mm in females and of 3.9 mm in supraorbital arterial position for both genders was observed. The mean depth of the supratrochlear artery was 3.34 [0.6] mm at rest, whereas the depth of the supraorbital artery was 3.54 [0.8] mm. CONCLUSIONS: The hypothesis that injecting soft tissue fillers next to the vertical glabellar line is safe because the supratrochlear artery courses deep to the crease should be rejected. Additionally, the glabella and the supraorbital region should be considered as an area of mobile, rather than static, soft tissues.

ABSTRACT

BACKGROUND: The first FDA-cleared, long-lasting, minimally invasive device for improving the appearance of cellulite was recently launched in Canada as a novel, tissue stabilized-guided subcision (TS-GS) system (Cellfina, Merz North America, Inc., Raleigh, NC). Clinicians from 2 of the first Canadian sites offering this procedure were interested in evaluating treatment efficacy and patient satisfaction after its first year on the market. OBJECTIVES: The authors sought to evaluate the efficacy of TS-GS and the level of patient satisfaction associated with the procedure. METHODS: Medical charts of female patients treated with the TS-GS system in 2017 were retrospectively analyzed at 2 Canadian centers. Measurements at baseline and 3 months posttreatment were assessed for patient satisfaction and physician-rated efficacy. Patient satisfaction was assessed using a 5-point Likert-type scale, and efficacy was evaluated through physician review of 2-deminsional and 3-dimensional photography, the Nürnberger-Müller Scale for cellulite, and the Global Assessment of Improvement Scale. RESULTS: We reviewed 25 patient charts. At month 3, 95.6% of patients were satisfied with treatment results and physician evaluations revealed that on average, patients displayed a 1-point improvement in their cellulite grades. Moreover, Global Assessment of Improvement Scale scores indicated that all patients had visible improvement in the global appearance of cellulite. No serious adverse events were observed within 3 months postprocedure. CONCLUSIONS: The physician ratings, patient satisfaction, and photographic evidence support the efficacy of the TS-GS system to manage grades 1 to 3 cellulite in women's thighs and buttocks. These findings indicate the safety of the TS-GS system.Level of Evidence: 4.

ABSTRACT

Background Earlier, digit viability judged the success of digital replantation. Now, utility health-related quality of life (HRQOL) measures can better assess the impact of digital replantation. Methods Overall, 264 digital injury patients were sent a regimen of utility measures: Disabilities of the Arm, Shoulder and Hand (DASH) score, European Quality of Life 5 Dimensions, visual analog scale (VAS), time trade-off (TTO), and standard gamble (SG). Overall, 51 patients responded completely to all of these-36 replantation patients and 15 revision amputation patients. The utility results of these patients were stratified between replantation versus revision amputation; dominant hand replantation versus nondominant hand replantation; and dominant hand revision amputation versus nondominant hand revision amputation. Results The mean VAS score of replant (0.84) and revision amputation (0.75) groups was significantly different (p = 0.05). The mean DASH score of dominant hand replantations (29.72) and nondominant hand replantations (17.97) was significantly different (p = 0.027). The dominant hand revision amputation had higher anxiety levels in comparison to nondominant hand revision amputation (p = 0.027). Patients with two or more digits replanted showed a significant decrease in VAS, TTO, and SG scores in comparison to patients who only had one digit replanted (p = 0.009, 0.001, and 0.001, respectively). Conclusions This study suggests that HRQOL can offer better indices for outcomes of digital replantation. This shows some specific replantation cohorts have a significantly better quality of life when compared with their specific correlating revision amputation cohort. These findings can be employed to further refine indications and contraindications to replantation and help predict the quality of life outcomes.

ABSTRACT

BACKGROUND: The aging process is a complex interplay of intrinsic and extrinsic factors across multiple layers of the face. Accordingly, combining aesthetic interventions targeting different manifestations of aging often leads to better results than single modalities alone. However, no guidelines for a pan-facial approach using multiple interventions have been published to date. OBJECTIVE: To develop consensus recommendations for the optimal combination and ideal sequence of botulinum toxin (BoNT), hyaluronic acid, calcium hydroxylapatite, and microfocused ultrasound with visualization (MFU-V) in persons of all Fitzpatrick skin types. METHODS AND MATERIALS: Fifteen specialists convened under the guidance of a certified moderator. Consensus was defined as approval from 75% to 94% of all participants, whereas agreement of ≥95% denoted a strong consensus. RESULTS: Optimal aesthetic treatment of the face begins with a thorough patient assessment and an individualized treatment plan. Spacing consecutive treatments 1 to 2 weeks apart allows for resolution of side effects and/or to assess results. For same-day treatments, BoNT and fillers may be performed together in either sequence, whereas MFU-V is recommended before injectable agents. CONCLUSION: Expert consensus supports a combination approach using multiple modalities in specific sequence for the safe and effective treatment of the aging face.
