Retrospective Review of the Laser Removal of Facial Cosmetic Tattoos.

BACKGROUND: Cosmetic facial tattoos have proven difficult to remove despite advancements in laser technology. OBJECTIVE: Review safety and efficacy of picosecond laser removal of cosmetic facial tattoos. METHODS MATERIALS: Retrospective chart review from January 2015 to January 2022 of patients undergoing tattoo removal of facial cosmetic tattoos. RESULT: A total of 33 patients were included in the review. The average number of treatments to obtain satisfactory results was 3. Sixty 6 percent of subjects were rated as "very much improved" with 76% to 100% of the tattoo removed and 34% of subjects were rated "much improved" with 51% to 75% of the tattoo removed. Thirty percent of subjects experienced unexpected changes in the tattoo color after initial treatment with 1,064-nm picosecond laser. CONCLUSION: Picosecond laser is an effective and safe treatment for cosmetic tattoos, and it highlights the underreported unmasking of an orange color postlaser treatment that can be successfully treated with a 532-nm PS laser.

Large Varicose Vein Closure: A Comprehensive Review.

BACKGROUND: Treatment of chronic venous disease and varicose veins has significant psychosocial and economic impact. The great saphenous vein is a common vein to develop incompetence and reflux and, therefore, been the focus of therapy for many years. OBJECTIVE: To review the published medical literature relating to large varicose vein closure and provide a guide for closure techniques' efficacy and safety. METHODS: A comprehensive search of the English language literature was performed up to and including December 2021. All references pertaining to large varicose vein closure were reviewed. RESULTS: There are multiple safe and effective minimally invasive methods to achieve occlusion of incompetent great saphenous vein, the most widely used of which is endovenous thermal ablation. Other nonthermal, tumescent, and nontumescent methods can also be used. CONCLUSION: Proper knowledge of vein anatomy, ultrasound, and vein closure procedures is needed to ensure safe and effective outcomes.

Cutaneous Vascular Compromise and Resolution of Skin Barrier Breakdown After Dermal Filler Occlusion-Implementation of Evidence-Based Recommendations Into Real-World Clinical Practice.

BACKGROUND: Vascular occlusions that threaten skin integrity, although not an emergency like those that threaten a patient's vision, is an urgent situation. Accurately interpreting physical examination findings is paramount. The use of high-dose, pulsed hyaluronidase is the mainstay of therapy; however, adjunctive measures that may optimize clearance of an occlusion and/or skin barrier repair such as the use of image guidance and hyperbaric oxygen should be considered. OBJECTIVE: To provide a review of the literature on the treatment of vascular occlusions threatening skin barrier integrity and develop a step-wise treatment guide. MATERIALS AND METHODS: The authors searched PubMed for peer-reviewed studies, consensus statements, case series, and case reports using a variety of keywords. RESULTS: Twenty-six articles focusing on vascular occlusions threatening the skin barrier were reviewed. The authors collectively agreed on treatments to reverse vascular occlusions and restore the skin barrier. The importance of high-dose, pulsed hyaluronidase was clear. Therapies that lacked evidence such as sodium thiosulfate were also revealed. CONCLUSION: A vascular occlusion that threatens skin integrity is an urgent matter which requires accurate interpretation of physical examination findings that will help guide intervention. High-dose, pulsed hyaluronidase along with adjunctive measures performed in a step-wise manner is key to an optimal outcome.

Sclerotherapy in Aesthetic Medicine: Myths and Realities.

BACKGROUND: Sclerotherapy is commonly performed for elimination of reticular and telangiectatic leg veins. There are several variations in practice, from the preparation to post-therapy directives. OBJECTIVE: To critically examine the misconceptions of sclerotherapy for aesthetic indications. MATERIALS AND METHODS: This review assesses evidence for and against each of the most common myths regarding sclerotherapy for aesthetic indications. RESULTS: Sclerotherapy can be safely used to treat veins in areas other than the lower extremities, with the exception of the face. Laser therapy is not superior to sclerotherapy for the treatment of small telangiectatic veins on the lower extremities. The type of syringe used to produce foam sclerotherapy is an important procedural consideration. After sclerotherapy, graduated compression stocking usage is a vital part of the procedure. Detergent sclerotherapy agents are similar, but not equivalent. Touch-up treatments after sclerotherapy should not be performed for 2 months post-treatment. Foam sclerotherapy does not have a high risk for air emboli. It is not advisable to treat the leg veins in "sections." Finally, one cannot reliably treat the telangiectatic veins without treating the feeding reticular veins for a satisfactory result. CONCLUSION: Many aspects of sclerotherapy have existing evidence to dictate best clinical practice.

A Novel Macrophage-Activating Gel Improves Healing and Skin Quality After CO2 Laser Resurfacing of the Chest.

BACKGROUND: After laser resurfacing, it is imperative that an appropriate postoperative regimen is followed for optimal wound healing. There is currently no consensus about which agents should be used. OBJECTIVE: To evaluate the safety and efficacy of a novel macrophage-activating gel in a Phase 2B trial to be used after fractionated ablative laser resurfacing of the chest. MATERIALS AND METHODS: Forty-two adults who received fractionated CO2 laser resurfacing of the chest were randomized (active or placebo) for 5 consecutive days after procedure. Skin quality at baseline and follow-up was assessed by a blinded evaluator using the Fitzpatrick-Goldman Wrinkle Scale. Subject satisfaction with skin healing and quality was also assessed. RESULTS: At 28 days according to the Fitzpatrick-Goldman Wrinkle Scale, 85% of subjects achieved an improvement of at least 33% for the active group versus 50% in the placebo group (absolute difference 35%; p = .04). Similarly, 75% of subjects achieved an improvement score of at least 33% in elastosis in the active group versus 35% in the placebo group at 28 days (40% absolute difference; p = .011). CONCLUSION: This study confirms the potent effects of the novel macrophage-activating gel for optimization of skin healing and quality after laser resurfacing of the chest.

Serious Adverse Events With Injectable Fillers: Retrospective Analysis of 7,659 Patient Outcomes.

BACKGROUND: In total, 2.7 million injectable filler treatments were performed in 2019 in the United States. Although generally considered to be a safe treatment modality, adverse events may occur in rare situations. OBJECTIVE: Analyze serious adverse events from injectable filler treatments, including infections, cutaneous necrosis, blindness, or delayed-onset nodule formation, spanning 11 years for 3 board-certified dermatologists and review their incidence, management, and outcomes. MATERIALS AND METHODS: A retrospective analysis was performed of injectable filler treatments spanning 11 years at a multipractitioner outpatient clinic. Serious adverse events were identified, and treatment measures were documented. A literature search was performed to determine recent trends and outcomes for comparison. RESULTS: Between January 2009 and August 2020, 18,013 mL of injectable filler was administered to 7,659 patients. Of the 18,013 mL administered, 74.1% comprised hyaluronic acid derivatives, 19.19% poly-l-lactic acid, and 6.71% calcium hydroxylapatite. Four serious adverse events were identified. Three events were delayed-onset skin nodule formation. One adverse event was related to vascular compromise and subsequent cutaneous necrosis. After appropriate treatment, all adverse events resolved without significant long-term sequelae. CONCLUSION: Serious adverse events associated with injectable fillers, when performed by board-certified dermatologists, are extremely rare and can be successfully managed with appropriate treatment.

A Randomized, Evaluator-Blind, Split-Face Study Evaluating the Safety and Efficacy of Calcium Hydroxylapatite for Jawline Augmentation.

INTRODUCTION: Jawline augmentation with calcium hydroxylapatite has not yet been evaluated in a prospective study with a split-face design. This study aims to perform the first randomized controlled, split-face study on the efficacy and safety of calcium hydroxylapatite for jawline augmentation using the needle and cannula technique. OBJECTIVE: To perform the first randomized controlled, split-face study on the efficacy and safety of calcium hydroxylapatite for jawline augmentation using the needle and cannula technique. MATERIALS AND METHODS: This is a single-site, randomized, evaluator-blind trial enrolling a total of 10 healthy subjects with at least Grade 1 (mild) on a 4-point Jawline Scale. One side of the face was randomized to receive 1 to 2 syringes of calcium hydroxylapatite with lidocaine (total of 3 mL) for correction of wrinkles and folds along the jawline using both the cannula and needle method, and a balancing treatment will be performed 1 month later. Blinded investigator and subject evaluations will be performed immediately after treatment and at the 30-, 60-, and 90-day visits. RESULTS: Ten subjects were enrolled and completed the trial. There was a improvement in the degree of wrinkling and skin sagging in the 4-point Jawline Scale, with an average of a 1.3-point improvement in the scale on the day of treatment and at the Day 30 visit, which remained improved greater than baseline after 3 months as graded by blinded investigators. The Clinician Global Aesthetic Improvement Score for the treated side versus control, as assessed by blinded investigators, demonstrated a improvement with a 2.3-point improvement on the 5-point scale, and by the final visit on Day 90, most patients had a much improved appearance from baseline. CONCLUSION: This study demonstrates that calcium hydroxylapatite is effective and safe for restoration and augmentation of the jawline using the unique needle and cannula technique.

A Systematic Review of Picosecond Laser in Dermatology: Evidence and Recommendations.

BACKGROUND AND OBJECTIVES: The use of picosecond laser in dermatology was originally focused on optimizing the removal of unwanted tattoos. Subsequent advances in this technology have broadened its clinical indications to include treatment of benign pigmented lesions, photodamage, melasma, and scar revision. In this systematic review, evidence-based recommendations are developed for the use of picosecond laser in dermatology. STUDY DESIGN/MATERIALS AND METHODS: A comprehensive search of the English language literature was performed up to and including November 2019. Relevant citations were individually evaluated, synthesized, and categorized based on the Level of Evidence. With the addition of the authors' combined clinical experience, clinical recommendations were developed. RESULTS: After application of inclusion and exclusion criteria, a total of 77 unique studies were evaluated. Treatment of benign pigmented lesions was associated with level I-IV evidence; rejuvenation was associated with level II evidence; melasma was associated with level II evidence; scar revision was associated with level II-III evidence; tattoo removal was associated with level I evidence. CONCLUSION: Picosecond laser is a safe and effective treatment modality for an increasing range of dermatologic indications. Further development of this technology is warranted. Lasers Surg.

A Randomized, Split-Face, Double-Blind Comparison Trial Between Fractionated Frequency-Doubled 1064/532 nm Picosecond Nd:YAG Laser and Fractionated 1927 nm Thulium Fiber Laser for Facial Photorejuvenation.

BACKGROUND AND OBJECTIVE: Fractionated lasers are a popular therapeutic option for facial photorejuvenation. In this study, we compare the safety, tolerability, and efficacy of a fractionated frequency-doubled 1064/532 nm picosecond Nd:YAG fractionated picosecond laser (FPL) versus a fractionated 1927 nm thulium fiber laser (TFL) for facial rejuvenation. STUDY DESIGN/MATERIALS AND METHODS: This was a double-blind, randomized, split-face comparison study involving 20 subjects. Facial halves were randomized to receive either FPL or TFL treatment. Three treatments were delivered at 1-month intervals. Subjects were followed up for 1, 3, and 6 months post-final treatment session and evaluated by blinded, non-treating investigators for dyspigmentation, erythema, keratosis, texture, and rhytids on a standardized scale. Subjects also recorded a quantitative daily diary rating healing progress for 14 days after every treatment session. RESULTS: Statistically significant improvements in elastosis, erythema, keratosis, dyschromia, and skin texture were noted in both treatment groups. There were no significant differences detected in clinical efficacy between the two groups. Subject daily dairies revealed statistically significant differences in tolerability during the immediate 14-day post-operative recovery period. The facial half treated with FPL displayed significantly less redness on days 3 and 4; significantly less swelling on day 5; significantly less crusting on days 1 through 9; significantly less peeling on days 3 through 9; and significantly less itch on days 4 and 7. There were no unexpected adverse effects observed. CONCLUSION: Both FPL and TFL are safe and effective treatment options for facial rejuvenation. FPL may be associated with significantly less downtime. Lasers Surg. Med. © 2020 Wiley Periodicals, Inc.

A Dynamically Cooled, Variable Spot-Sized 1,064 nm Neodymium-doped Yttrium Aluminum Garnet Laser as a Treatment Option for Facial Reticular Veins.

BACKGROUND: Facial reticular veins can be treated with laser therapy, sclerotherapy, or surgical removal. The use of a 1,064 nm neodymium-doped yttrium aluminum garnet (Nd:YAG) laser has been reported to be successful in the treatment of facial reticular veins. OBJECTIVE: To report a large retrospective study examining the efficacy, side effects, and satisfaction of a dynamically cooled, variable spot-sized 1,064 nm Nd:YAG laser for the treatment of facial reticular veins in the periorbital and temporal area. PATIENTS AND METHODS: Contact was made with 100 patients from 2006 to 2019 who underwent treatment with a 1,064 nm Nd:YAG laser for facial reticular veins through office follow-up or telephone interviews. Percent resolution of veins, satisfaction, and adverse effects were evaluated. RESULTS: Eighty-nine of the 100 patients ranked their satisfaction with the treatment as 3 or very satisfied. Most patients reported 75% to 100% improvement. The most commonly reported adverse event seen after treatment was mild edema. Sixty-eight percent of patients reported no adverse effects at all. CONCLUSION: The dynamically cooled, variable spot-sized 1,064 nm Nd:YAG laser is a safe and effective treatment for facial reticular veins with minimal side effects. The results are usually immediate and, based on the long-term follow-up, tend to be long lasting.

Nonsurgical Postpartum Abdominal Rejuvenation: A Review and Our Experience.

BACKGROUND: A significant population of aesthetic patients are postpartum women motivated to achieve a more youthful abdomen. Although traditionally, abdominoplasty was the treatment of choice, minimally invasive procedures have grown in popularity because of minimal downtime and the favorable side effect profile. so many women share concerns regarding their postpartum abdominal appearance, a limited number of studies focus specifically on postpartum abdominal rejuvenation. OBJECTIVE: To review pertinent aspects of abdominal anatomy, associated changes with pregnancy, available nonsurgical cosmetic procedures, and to provide our experience to help guide treatment combinations which comprehensively address the concerns of the postpartum patient. MATERIALS AND METHODS: A review of the literature surrounding nonsurgical treatment options for postpartum abdominal lipohypertrophy, muscle changes, tissue laxity, and striae gravidarum, along with the authors' experience in this area are provided. CONCLUSION: This review summarizes available nonsurgical modalities to address postpartum abdominal defects, including procedures that tone muscles, reduce fat, tighten skin, and improve the appearance of striae. Both the published literature and the authors' experience favor a combination of treatments to address the various lamellae affected by pregnancy. Further clinical trials focusing on the postpartum patient would further help create a standardized approach for postpartum abdominal rejuvenation.

Prospective Clinical Trial of the Latest Generation of Noninvasive Monopolar Radiofrequency for the Treatment of Facial and Upper Neck Skin Laxity.

BACKGROUND: Aging of the face and upper neck is a complex process characterized by loss of collagen and elastic fibers, resulting in clinical skin laxity. Noninvasive interventions such as monopolar capacitively coupled radiofrequency (MRF) have gained popularity, offering a safer and more convenient alternative to traditional surgical face lift. The latest MRF device features larger tips, vibration, cooling, and impedance matching. OBJECTIVE: We performed the first open-label clinical trial, measuring the efficacy, safety, and patient satisfaction of this device for noninvasive lifting and tightening of the face and upper neck. MATERIALS AND METHODS: Forty subjects 30 to 60 years of age with mild/moderate skin laxity of the face and upper neck were enrolled. After pretreatment with ketorolac 60 mg intramuscular injection, subjects underwent treatment with MRF. Follow-up evaluations were performed on Days 30, 60, and 180. RESULTS: Our study demonstrated that the newest generation MRF produced statistically significant improvement in skin laxity 6 months post-treatment, especially in the jowls and melolabial folds. According to the Investigator Global Aesthetic Improvement Score, 73% of subjects had improvement at 6 months post-treatment. Subject satisfaction and improvement questionnaires supported these findings. CONCLUSION: Our data coupled with the excellent adverse effect profile validates MRF as an attractive treatment modality for facial and upper neck skin laxity.

Collagenase Clostridium Histolyticum-aaes for the Treatment of Cellulite in Women: Results From Two Phase 3 Randomized, Placebo-Controlled Trials.

BACKGROUND: Fibrous septae play a role in contour alterations associated with cellulite. OBJECTIVE: To assess collagenase clostridium histolyticum-aaes (CCH) for the treatment of cellulite. MATERIALS AND METHODS: Two identically designed phase 3, double-blind, randomized studies (RELEASE-1 and RELEASE-2) were conducted. Adult women with moderate/severe cellulite (rating 3-4 on the Patient Reported Photonumeric Cellulite Severity Scale [PR-PCSS] and Clinician Reported PCSS [CR-PCSS]) on the buttocks received up to 3 treatment sessions of subcutaneous CCH 0.84 mg or placebo per treatment area. Composite response (≥2-level or ≥1-level improvement from baseline in both PR-PCSS and CR-PCSS) was determined at Day 71. RESULTS: Eight hundred forty-three women received ≥1 injection (CCH vs placebo: RELEASE-1, n = 210 vs n = 213; RELEASE-2, n = 214 vs n = 206). Greater percentages of CCH-treated women were ≥2-level composite responders versus placebo in RELEASE-1 (7.6% vs 1.9%; p = .006) and RELEASE-2 (5.6% vs 0.5%; p = .002) and ≥1-level composite responders in RELEASE-1 (37.1% vs 17.8%; p < .001) and RELEASE-2 (41.6% vs 11.2%; p < .001). Most adverse events (AEs) in the CCH group were injection site related; few CCH-treated women discontinued because of an AE (≤4.3%). CONCLUSION: Collagenase clostridium histolyticum-aaes significantly improved cellulite appearance and was generally well tolerated.

Intense Pulsed Light: A Methodical Approach to Understanding Clinical Endpoints.

BACKGROUND: Intense Pulsed Light (IPL) is a non-coherent polychromatic broadband filtered flashlamp that emits light in the spectrum of approximately 400–1200 nm. Its effects on photorejuvenation are well documented. The goal of this study is to help practitioners better conceptualize and fine tune IPL device settings in order to produce the most effective and safest clinical outcome. MATERIALS/METHODS: This was a prospective study testing several filters (515 nm; 560 nm; 590 nm and 530–650; 900–1200 nm vascular filter), fluences, pulse durations, and pulse numbers (ie, multiple sequence pulsing or MSP) with a new IPL system. RESULTS: Post-procedure erythema response was more pronounced with increasing fluence, decreasing wavelength, fewer pulses and shorter pulse duration. The exception was the 515 nm filter with regard to pulse duration, which was observed to have a more pronounced response with longer pulse durations. The overall clinical outcome at the 4-week follow-up visit demonstrated greatest improvement in erythema and pigmentation using the 515 nm filter on a Fitzpatrick Skin Type III individual. CONCLUSION: Greatest clinical endpoint response at 4-week follow-up was observed with more robust initial responses. This was most apparent at higher fluence levels and fewer pulse counts. However, when the IPL is pushed to aggressive parameters, there is risk of hypopigmentation and hair loss as seen in this case study. Skin type is an important consideration when using IPL and MSP adds to its safety profile. J Drugs Dermatol. 2021;20(2):203-207. doi:10.36849/JDD.5638.

Chart Review Presenting Safety of Injectable PLLA Used With Alternative Reconstitution Volume for Facial Treatments.

BACKGROUND: Since the approval of Sculptra Aesthetic, the amount of sterile water used to reconstitute the product has gradually increased in clinical practice. A retrospective chart review was conducted to evaluate patient safety associated with a larger reconstitution volume, and to investigate specific parameters for how Sculptra Aesthetic is used in a real-world clinical setting. OBJECTIVE: The primary objective of the study was to evaluate the safety of Sculptra Aesthetic when using a reconstitution volume of 7 to 10 mL, via collection of adverse events related to the product or injection procedure reported in medical records. METHODS: This was a multi-center, retrospective chart review conducted in the US. Medical records for subjects treated in the facial area with Sculptra Aesthetic reconstituted to 7–10 mL were reviewed to obtain information about demographics, treatment data, and adverse events. Each injector completed a questionnaire regarding reconstitution and injection procedures generally used. RESULTS: There were 4483 treatments performed in 1002 subjects; nearly half (48%) had 3 or 4 treatments during the studied period. Subjects most commonly received treatment in the midface/cheek area (97%), temple (94%), and jawline (54%). All injectors indicated adding lidocaine to the solution, resulting in total volumes of 8–10 mL. Adverse events were reported by 3.6% of subjects, all mild in intensity. Nodules were reported by 4 subjects (0.4%). CONCLUSION: The low number of AEs reported in this retrospective chart review suggests that facial aesthetic treatment with PLLA reconstituted to a final volume of 8–10 mL, including anesthetics, is associated with a favorable risk benefit ratio. J Drugs Dermatol. 2021;20(1):18-22. doi:10.36849/JDD.5631.

Idiopathic guttate hypomelanosis: Presentation and Management.

Idiopathic guttate hypomelanosis (IGH) is a benign, typically asymptomatic, acquired leukoderma characteristically affecting mature individuals. Although the etiopathogenesis is unclear, chronic sun exposure and senile degeneration are important triggers. Researchers have been engaged in a continuous effort to unveil the gray areas encompassing different aspects of IGH pathogenesis. IGH is a clinical diagnosis; however, histopathology and dermoscopy may aid in quetionable cases. Patients often seek cosmetic treatment. There has been no standard therapy for this condition. Newer treatment modalities range from topical agents to procedure-based therapies and have enhanced the therapeutic armamentarium. Here we discuss the pathogenesis, presentation, and management of IGH.

The Second of Two One-Year, Multicenter, Open-Label, Repeat-Dose, Phase II Safety Studies of PrabotulinumtoxinA for the Treatment of Moderate to Severe Glabellar Lines in Adult Patients.

BACKGROUND: PrabotulinumtoxinA is a 900-kDa botulinum toxin type A produced by Clostridium botulinum. OBJECTIVES: The authors sought to investigate the safety of prabotulinumtoxinA for treatment of glabellar lines. METHODS: This was a multicenter, open-label, repeat-dose, 1-year phase II safety study. Adults with moderate to severe glabellar lines at maximum frown, as independently assessed by both investigator and patient on the validated 4-point photonumeric Glabellar Line Scale (0 = no lines, 1 = mild, 2 = moderate, 3 = severe), were enrolled. On day 0, patients received an initial treatment (IT) of 20 U prabotulinumtoxinA (4 U/0.1 mL final vacuum-dried formulation injected into 5 glabellar sites). On and after day 90, patients received a repeat treatment (RT) if their Glabellar Line Scale score was ≥2 at maximum frown by investigator assessment. Safety outcomes were evaluated throughout the study. RESULTS: The 570 study patients received a median total dose of 60 U, that is, 3 treatments. Sixty-one patients (10.7%) experienced adverse events (AEs) assessed as possibly study drug related; 6.5% experienced study drug-related AEs after the IT. With each RT, progressively lower percentages of patients experienced study drug-related AEs. Eight patients (1.4%) experienced study drug-related AEs of special interest: 5 experienced eyelid ptosis (0.9%), 3 eyebrow ptosis (0.5%), 1 blepharospasm (0.2%), and 1 blurred vision (0.2%). Seven patients (1.2%) experienced serious AEs, but none were study drug related. A total of 4060 serum samples were tested for antibotulinum toxin antibodies; no seroconversion was observed. CONCLUSIONS: The safety of RTs of 20 U of prabotulinumtoxinA for moderate to severe glabellar lines was confirmed in this second phase II study based on a broad range of outcomes.

Comparative Evaluation of 15 Laser and Perfluorodecalin Combinations for Tattoo Removal.

BACKGROUND AND OBJECTIVES: We present a case of laser tattoo removal treated with 15 different combinations using picosecond 1064 nm, picosecond 755 nm, nanosecond 755 nm, and a fractionated CO2 laser, both with and without a perfluorodecalin (PFD) patch to ascertain the most effective approach. STUDY DESIGN/MATERIALS AND METHODS: A single lower extremity black tattoo was divided into 15 treatment sections allowing for testing of various laser and PFD combinations. Sectioned treatment was conducted until a treatment superiority was noted. RESULTS: After two sessions using sectioned combination treatments with a 4-week interval clinically significant results were produced. CONCLUSIONS: The combination of picosecond 1064 nm, picosecond 755 nm, and a fractionated CO2 laser without the PFD patch showed superior clinical improvement over the other combinations.

Comparison of the Safety and Efficacy of Foam Sclerotherapy With 1: 2 Polidocanol to Air Ratio Versus 1: 4 Ratio for the Treatment of Reticular Veins of the Lower Extremities.

BACKGROUND: Foam sclerotherapy is a common treatment of lower extremity reticular veins. The effect of different liquid-gas ratios on foam stability and efficacy has been controversial. OBJECTIVE: To evaluate the use of 2 different polidocanol (POL) to air ratios for the treatment of reticular veins of the lower extremities. METHODS AND MATERIALS: Patients with lower extremity reticular veins were randomized to foam sclerotherapy with POL mixed with 4 mL of room air for one lower extremity or 2 mL for the other lower extremity. All telangiectasias were treated with glycerin immediately after treatment of the reticular veins. Adverse events (AEs) and efficacy were evaluated by both subject and blinded investigator. RESULTS: Thirty subjects completed the study. No statistically significant difference was seen in AEs between the 2 different POL to air ratios by subject questionnaire and blinded investigator scores at all time points. Subjects and blinded investigator reported a mean improvement between 0% and 50% at Day 21 and 26% to 75% at Day 90, which was not significantly different between groups. CONCLUSION: Two different POL to air ratios, 1:2 versus 1:4, were similarly safe and efficacious for the treatment reticular veins of the lower extremities.

Evaluation of Long-Term Outcome and Patient Satisfaction Results After Tumescent Liposuction.

BACKGROUND: Liposuction is one of the most common cosmetic surgery procedures around the world. Tumescent liposuction using local anesthesia has been shown to be the safest technique. Few long-term studies of results and satisfaction have been published on tumescent liposuction. OBJECTIVE: To evaluate long-term results and patient satisfaction of tumescent liposuction in a single-center institution. METHODS: Patients (n = 600) who had tumescent liposuction performed in our practice from 2002 to 2014 were contacted through letter, email, or phone to complete a questionnaire survey and in-office follow-up visit regarding their past liposuction procedures. RESULTS: Thirty-two patients (n = 32) completed the patient questionnaire survey and followed up in the office. Surgeon and blinded evaluators saw significant differences in both the neck volume (surgeon evaluator: 2.42 vs. 0.71, p < .01; blinded evaluator: 2.8-1, p = .02) and Investigator Assessment Skin Laxity scales (blinded evaluator: 1.14 vs. 0.77, p < .01 for laxity and 1.33 vs. 0.75, p < .01 for firmness; surgeon evaluator: 1.17 vs. 0.83, p = .01 for laxity and 1.31 vs. 0.83; p < .01 for firmness). The mean follow-up period was 8.9 years overall and 9.9 years for the neck. Overall, 85.7% of the patients would recommend liposuction to their friends and family members. CONCLUSION: Tumescent liposuction is a safe procedure with long-lasting results and high patient satisfaction.
