RESUMO

For the general dentist, the use of BTA and dermal fillers confers the ability to exert control over the soft tissues surrounding the mouth to better create a harmonious smile. The injection of BTA and fillers into the facial musculature and dermis requires a level of finesse to achieve the desired outcomes. A sound understanding of the mechanisms of action and the ability to manage potential complications are also necessary, because the dentist administering BTA and dermal fillers must be competent to the same level as other providers who have traditionally been the gatekeepers of such agents.

RESUMO

Piercings and tattoos have gained popularity across all cultural environments during the past century, and one in ten Europeans are now pierced. While tattoos are often restricted to the rest of the body, piercings are common at facial sites such as ears, nose, lips, and tongue. Complications following piercings are not uncommon. Infections can rapidly spread across the auricular cartilage and require antibiotic and often surgical treatment. Mild trauma (i.e., piercing the earlobe) can lead to excessive scar formation due to fibroblast proliferation. Keloids have a particularly high rate of recurrence and are therefore difficult to treat. Due to recent developments in the field of permanent makeup, tattooing techniques are also increasingly applied in the head and neck region. Here, complications such as infection or allergic reactions can occur. Topical medication or laser procedures are the usual therapeutic options.

RESUMO

BACKGROUND: Objective dynamic assessments are central to the evaluation of facial rejuvenation treatments. This study used three-dimensional digital stereophotogrammetry to generate a quantitative dynamic assessment of facial strain and hyaluronic acid filler efficacy. METHODS: Thirty women (aged 41 to 65 years) with moderate to severe bilateral nasolabial folds and marionette lines received Restylane Refyne, Restylane Defyne, or both, and were compared to a "younger" untreated group (n = 20; aged 25 to 35 years). Three-dimensional videos were collected at baseline and at day 42. Dynamic strain was analyzed at the marionette lines and nasolabial folds as subjects went from a neutral position through a series of facial expressions. RESULTS: Baseline nasolabial folds and marionette lines showed statistically significant (p ≤ 0.05) differences in the level of stretch between younger and older untreated subjects, with higher stretch profiles observed in the older cohort. In the older cohort, filler treatment reduced peak strain (stretch) in the nasolabial folds and marionette lines compared with baseline across all tested expressions, resembling the youthful strain profile of the younger untreated control group. Treatment was well tolerated. CONCLUSIONS: Quantitative dynamic strain analysis is an innovative method for evaluating the dynamic face following dermal fillers and provides objective evidence that such treatment results in stretch levels resembling a younger phenotype in areas prone to the effects of facial aging. The strain reduction following filler treatment objectively conveys a dermal tightening effect, likely secondary to the volumization of treated areas. Additional studies will refine the technology and associated procedures to optimize quantitative dynamic strain analysis for treatment planning and patient outcome optimization. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

RESUMO

BACKGROUND: In recent years, microneedling has been increasingly used to treat a number of dermatologic conditions, including scars. Although initial studies demonstrated improvement of (mostly) atrophic scars with microneedling, the number of patients evaluated was relatively small, and the devices and treatment protocols used and posttreatment follow-up varied widely. Through this prospective observational study, the results of microneedling on 20 patients with a variety of scars are described. METHODS: One hundred twenty consecutive patients (skin phototypes I through VI) with facial and nonfacial scars from a variety of etiologic sources (acne, trauma, surgery) were treated using a mechanical microneedling device. No additional treatments (topical or intralesional) were applied. Two assessors blinded to treatment protocol rated clinical improvement of scars 1, 3, 6, and 12 months after treatment on a five-point scale. Side effects were monitored and tabulated. RESULTS: Patients received one to six consecutive monthly microneedling treatments. All scars improved at least 50 percent after an average of 2.5 treatments. Over 80 percent of patients had 50 to 75 percent improvement, and 65 percent of patients demonstrated over 75 percent improvement. No significant clinical differences were observed in treatment responses of facial scars versus nonfacial scars nor between responses of atrophic acne scars and traumatic or surgical scars. CONCLUSIONS: This study supports the use of microneedling for various facial and nonfacial scars across a broad range of skin phototypes with minimal risk of adverse effects. Further studies will help to establish standardized protocols to optimize treatment outcomes for different scar types. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

RESUMO

BACKGROUND: Sequential compression devices are often considered a mainstay of prophylaxis against deep venous thromboses in surgical patients. The devices are believed to produce a milking action on the deep veins to prevent venous stasis. A systemic fibrinolytic effect has also been proposed, adding a second mechanism of action. The plasma levels of tissue plasminogen activator and plasminogen activator inhibitor-1 reflect fibrinolytic activity. METHODS: A randomized trial was conducted among 50 consecutive plastic surgery outpatients undergoing cosmetic surgery performed by the author under total intravenous anesthesia and without paralysis. Patients were randomized to receive calf-length sequential compression devices or no sequential compression devices during surgery. Blood samples were obtained from the upper extremity preoperatively and at hourly intervals until the patient was discharged from the postanesthesia care unit. Tissue plasminogen activator and plasminogen activator inhibitor-1 levels were measured. Ultrasound surveillance was used in all patients. There was no outside funding for the study. RESULTS: All patients agreed to participate (inclusion rate, 100 percent). No patient developed clinical signs or ultrasound evidence of a deep venous thrombosis. There were no significant changes in tissue plasminogen activator levels or plasminogen activator inhibitor-1 levels from the preoperative measurements at any hourly interval and no differences in levels comparing patients treated with or without sequential compression devices. CONCLUSIONS: No significant change in systemic fibrinolytic activity occurs during outpatient plastic surgery under total intravenous anesthesia. Sequential compression devices do not affect tissue plasminogen activator or plasminogen activator inhibitor-1 levels, suggesting no fibrinolytic benefit. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, I.

RESUMO

BACKGROUND: A practical application of three-dimensional printing technology has been considered a difficult area in rhinoplasty. However, the patient-specific three-dimensionally printed rhinoplasty guide based on the simulation program the authors developed could be a solution for minimizing the gap between simulation and actual surgical results. The aims of this study were to determine how a three-dimensional rhinoplasty guide based on three-dimensional simulation would link the patient to the surgeon to investigate its effectiveness. METHODS: Fifty patients who underwent rhinoplasty between January of 2017 and February of 2018 were included in this study. The patients were consulted about the desired shape of their nose based on preoperative three-dimensional photography. The confirmed three-dimensional simulation was sent to a manufacturing company for three-dimensionally printed rhinoplasty guides. In the guide group, rhinoplasty was performed based on the three-dimensionally printed rhinoplasty guide, and in the control group, procedures were performed based on the surgeon's intuition. RESULTS: The intraclass correlation coefficient test for comparing the simulated and postoperative measurements showed higher correlation in the three-dimensional printing guide group: higher correlation 11.3 percent in nasal tip projection, 21.6 percent in dorsum height, and 9.8 percent in nasolabial angle. The postoperative result of the nasal dorsum had a statistically significant difference between the two groups (p < 0.05). CONCLUSIONS: This study demonstrated the usefulness of the three-dimensionally-printed rhinoplasty guide, which delivers the preoperative simulated image in the actual clinical practice of rhinoplasty. This approach could cause a paradigm shift in simulation-based rhinoplasty. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

RESUMO

BACKGROUND: The study proposes a novel protocol for targeting the jowls using deoxycholic acid (DCA) injections, with emphasis on safety and feasibility of the procedure. METHODS: This prospective study was conducted at a cosmetic practice between June 2016 and May 2017. Twelve consecutive patients seeking reduction/improvement in mild/moderate jowl fat were injected with DCA subcutaneously in a predefined circular area 1.0 cm above the mandibular border. Treatment response was assessed using physician-evaluated Global Aesthetic Improvement Scale (GAIS) and Subject GAIS. RESULTS: Twelve patients (11 women and 1 man) with mild (n = 8) or moderate (n = 4) jowls were treated. After the first treatment, GAIS responses for 24 jowls showed 5 jowls with vast improvement, 15 with moderate improvement, and 4 with no change. After the second session for 5 jowls in 3 patients, GAIS responses showed vast improvement in 4 jowls and moderate improvement in 1. Adverse events included induration (n = 4), bruising (n = 6), numbness (n = 2), pain (n = 5), redness (n = 3), edema (n = 9), and dysphagia (n = 1). CONCLUSION: Results of this early experience showed that DCA injections were safe and effective for nonsurgical jowl reduction.

RESUMO

BACKGROUND: Patient-reported outcomes are increasingly recognized as important measures of treatment benefit. OBJECTIVE: To evaluate subject-reported satisfaction and impact outcomes with onabotulinumtoxinA treatment in neurotoxin-naive adults with forehead lines (FHL), glabellar lines (GL), and crow's feet lines (CFL). METHODS: This Phase 3 study randomized 787 subjects to onabotulinumtoxinA 64 U (FHL 20 U, GL 20 U, and CFL 24 U), 40 U (FHL 20 U, GL 20 U, and CFL placebo), or placebo in double-blind Period 1. Subjects could receive up to 2 additional 64 U treatments in open-label Period 2. Patient-reported outcomes were assessed using the validated Facial Line Satisfaction Questionnaire (FLSQ) and 11-item Facial Line Outcomes (FLO-11) Questionnaire. RESULTS: The proportion of subjects mostly or very satisfied was significantly greater with onabotulinumtoxinA 64 U and 40 U versus placebo (87.9% and 81.4% vs 3.2%; p < .0001). Responder rates on FLSQ Impact Domain, FLO-11 Items 1, 4, 5, and total score were significantly greater with onabotulinumtoxinA versus placebo on Day 30 (p < .0001). Responder rates favoring onabotulinumtoxinA in Period 1 were maintained with repeated onabotulinumtoxinA 64 U treatment in Period 2. CONCLUSION: OnabotulinumtoxinA treatment was associated with high subject satisfaction and significant improvements in appearance-related psychological and emotional impacts.

RESUMO

BACKGROUND: Hyaluronic acid (HA) fillers are the most commonly used fillers for soft-tissue augmentation. The face is a dynamic structure. Facial rejuvenation by filler products depends on mechanical forces on the region of the face. The successful use of injectable HA fillers requires an understanding of the options available. OBJECTIVE: The purpose of this study is to measure the rheological properties of HA fillers and to clarify how to select these fillers considering their rheological properties. MATERIALS AND METHODS: Rheological characterization was performed on 41 fillers. Physical parameters directly linked to product performance were measured. RESULTS: The properties of the HA fillers varied. These findings provide a basis for selection guideline regarding rheological properties in facial rejuvenation. CONCLUSION: The authors' report is the largest study to determine the rheological properties of HA fillers to date. Understanding the fillers' properties can help physicians select the appropriate fillers for more predictable and sustainable results.

RESUMO

BACKGROUND: ATX-101 is approved for submental fat reduction. OBJECTIVE: To characterize the histological effect of ATX-101 injection into subcutaneous fat. METHODS: This Phase 1 open-label study enrolled 14 adults to receive injections of ATX-101 into abdominal fat at varying concentrations (0.5%, 1.0%, 2.0%, or 4.0%), volumes (0.2 or 0.4 mL), spacing (0.7, 1.0, or 1.5 cm), and time points before scheduled abdominoplasty (1, 3, 7, or 28 days). During abdominoplasty, tissue was excised and preserved for histology. RESULTS: All injection paradigms resulted in histological changes confined to the subcutaneous layer, which were more prominent at higher concentrations and independent of volume and spacing. Key features at Day 1 after injection were adipocytolysis, blood vessel injury, neutrophilic inflammation, and lysis of locally present neutrophils. At Day 3, inflammation was reduced versus Day 1, and hemorrhage and lipid lake formation (at higher concentrations) were observed. Day 7 samples exhibited prominent adipocytolysis, mild inflammation, lipid-laden macrophages in the septae, and repair of vascular injury. At Day 28, inflammation was largely resolved and prominent features were septal thickening, neovascularization, and atrophy of fat lobules. CONCLUSION: Subcutaneous injection of ATX-101 induces adipocytolysis and local inflammation with septal thickening and resolution of inflammation by 28 days after injection.

RESUMO

BACKGROUND: Nontuberculous mycobacterium (NTM) infection following cosmetic procedures usually results from inadequate sterile techniques and contamination from nonsterile water. These infections are difficult to diagnose and treat. OBJECTIVE: This study aimed to describe the characteristics of NTM infections acquired after an aesthetic procedure, identify high-risk patients and high-risk cosmetic procedures, and provide a diagnostic and management algorithm for NTM infections occurring after cosmetic procedures. METHODS: On December 20, 2017 an online search of the Medline database was done. All articles describing NTM infection in cosmetic procedures were included in this review. RESULTS: In total, 92 patients with a mean age of 38.35 years were included in this review. Cosmetic procedures performed in the Dominican Republic were the most common source of infection and were noted in 33 patients. The procedure that resulted in the highest proportion of the infections was mesotherapy (34%). In most of the cases, the diagnosis was missed at the initial presentation and a short course of inadequate antibiotics was unsuccessful. CONCLUSION: Nontuberculous mycobacterium infections are hard to diagnose and difficult to treat, sometimes leading to severe irreversible sequalae. Aesthetic practitioners should know when to suspect and how to prevent, diagnose, and treat NTM infections.

RESUMO

BACKGROUND: The aesthetic use of botulinum toxins is widely accepted in routine treatment of glabellar lines. OBJECTIVE: To strengthen existing efficacy and safety data, and examine subject satisfaction concerning abobotulinumtoxinA (ABO) treatment for moderate to severe glabellar lines. MATERIALS AND METHODS: A 150-day prospective, single-dose, multicenter, randomized, parallel-group, placebo-controlled, double-blind study of 300 subjects treated with ABO (50 Units [U]). Response was defined as having no or mild glabellar lines after treatment (primary objective was Day 30 response). Glabellar line severity, onset and duration of effect, satisfaction, treatment emergent adverse events (TEAEs), and treatment-related adverse events (TRAEs) were assessed. RESULTS: Median time to onset of effect was 2 days. Day 30, ABO treatment response was 89% and 85% for investigator and subject assessments, respectively (p < .001 vs placebo). At Day 120, 60% of subjects demonstrated ≥1 grade improvement and 45% at Day 150. Subject satisfaction concerning glabellar line appearance was high (93%) at Day 14 and maintained by 35% through Day 150 with ABO treatment. No serious AEs were related to study treatment. CONCLUSION: Most ABO-treated subjects sustained ≥1 grade glabellar line improvements over 120 days, and satisfaction was maintained by >30% of subjects throughout 150 days. ABO was well tolerated.

RESUMO

BACKGROUND: Microneedling is a popular, minimally invasive skin rejuvenation modality for acne scarring. Recent reports have evaluated the efficacy and safety of microneedling monotherapy and combination treatment for scarring. OBJECTIVE: This review aims to systematically analyze the current literature on microneedling techniques used for acne scarring. METHODS: A PubMed search (2009-current) was used to identify literature on microneedling treatment for acne. All randomized and nonrandomized clinical trials, case cohorts, case reports, and case series were included with the exception of 2 studies, which were excluded due to unavailability. RESULTS: All 33 articles evaluated showed improvement of acne scar appearance after microneedling treatment. Evidence was inconsistent when comparing microneedling monotherapy to dual therapy or to fractional laser treatment. CONCLUSION: Microneedling improves acne scarring, and further studies are needed to compare microneedling with other minimally invasive treatments.

RESUMO

BACKGROUND: Dermal necrosis is a rare yet serious risk associated with cosmetic filler injections, and although current consensus recommends the use of hyaluronidase injections in cases of hyaluronic acid filler, the efficacy of topical nitroglycerin as a treatment has not yet been fully investigated. OBJECTIVE: To review the literature on tissue necrosis resulting from soft tissue augmentation and to highlight the use of topical nitroglycerin as a first-line treatment. METHODS: A review of the literature was performed with no time limitations resulting in 35 articles and 66 patients who experienced tissue necrosis secondary to injectable fillers. Articles were reviewed for pertinent information and presented. RESULTS: Only 7 of the 66 reported cases (10%) used topical nitroglycerin as a treatment. Six of 7 (85%) were successful in halting the impending necrosis. Fifty-nine patients received alternative treatments, with hyaluronidase injection being the most common. Few reports of novel treatments for necrosis included the use of topical growth factors and injection of adipose-derived stem cells. CONCLUSION: Topical nitroglycerin is a potentially effective and underused treatment for tissue necrosis from soft tissue augmentation, but because data are very limited, topical nitroglycerin should be used in conjunction with hyaluronidase injections in cases of hyaluronic acid filler dermal necrosis.

RESUMO

Introduction: Microfocused ultrasound (MFU) is a heat technology that is developed from focused ultrasound (FU) used in a high intense mode to generate heat (HIFU). Patient assessment is very complex and involves more than just addressing complaints. It is a challenge to evaluate, decide on options, and give treatments that guarantee the best outcomes. In order to facilitate the process, the authors divided the protocol into five steps: Assess (expectations, features); Decide (which depth to customize); Select (choose a number of lines to achieve the objective); Plan (combination, if needed); Treat (documentation, safety, and comfort). Methods: The PubMed search engine was used to search all publications from 1900­2019 that mention HIFU. The information collected was then grouped into the five protocol steps. Discussion: MFU is a focused ultrasound device that, at certain energy levels, produces heat over 55ºC at the focal point, which leads to thermal coagulation points (TCPs) in the target tissue. The creation of TCPs leads to a healing cascade, ending with neocollagenesis and neoelastogenesis. At different levels, this can bring about either a lifting effect or skin tightening, depending on the structure targeted. Therefore, the two most important tools for precision and efficacy of treatment are visualization with ultrasound and real-time evaluation of severity and structural changes (such as bone or fat loss). Conclusion: MFU-V is a well-known and, based on the evidence, an effective tool for non-invasive lifting and skin tightening. The secret to successful use of the device is to assess adequately patient needs and expectations and plan ahead for the combination of other treatment if necessary to achieve the desired outcome.

RESUMO

BACKGROUND: Hand rejuvenation has become increasingly popular, but there are few reports published on the use of hyaluronic acid gels for correction of volume deficits in the dorsal hand. METHODS: This study evaluated the efficacy and safety of large-gel-particle hyaluronic acid with lidocaine, a 20-mg/ml hyaluronic acid gel with 0.3% lidocaine, compared to no treatment for the correction of volume deficits in the dorsal hand. This was a prospective, multicenter, split-hand study in 90 subjects who received treatment with product in one hand. The primary efficacy endpoint was based on a 1 point of improvement with treatment versus no treatment according to the Merz Hand Grading Scale at week 12. Other assessments included Central Independent Photographic Reviewers evaluations of hand photographs, Global Aesthetic Improvement Scale, subject satisfaction, and safety. RESULTS: The mean injection volume was 2.1 ml at the first treatment. Subjects demonstrated significantly higher response rates with treatment compared to no treatment at week 12 (85.9 percent versus 21.2 percent) and at weeks 16, 20, and 24 (p < 0.0001). Photographic Reviewers assessments showed consistently greater improvements in the treated hands compared with the untreated hands from week 12 to week 24. Most subjects and investigators (≥92.8 percent) reported improvements in Global Aesthetic Improvement Scale score across all time points with treatment. Treatment-related adverse events were reported in seven subjects (7.9 percent). Most of these were mild, and none were serious. CONCLUSION: Hyaluronic acid with lidocaine is safe, effective, and well tolerated for the correction of volume deficits in the dorsal hand. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, II.
