Transcutaneous lower eyelid blepharoplasty with micro-autologous fat transplantation harvested from orbital fat pads for lower eyelid aging treatment.

The aging process of lower eyelids results in lower eyelid wrinkles, tear troughs, and eye bags. Many therapies have been described for treatment of lower eyelid aging, and transcutaneous blepharoplasty is often used for treating cases with eyebags and dermatochalasis. However, it may cause depression near the medial orbit resulting in a hollowed look. In the present study, we developed an innovative method transferring the herniated fatty tissue to volume loss area during the surgical procedure of transcutaneous lower eyelid blepharoplasty by means of micro-autologous fat transplantation harvested from resected orbital fat pads. Besides, we also analyze it efficacy and safety compared with traditional methods of transcutaneous lower eyelid blepharoplasty. We reviewed the records of the patients who underwent transcutaneous lower eyelid blepharoplasty with and without micro-autologous fat transplantation, for lower eyelid aging improvement. We used global aesthetic improvement scale, Hirmand's classification system, and Wrinkle Severity Rating Scale to evaluate the cosmetic outcome at 1 week, 1 month, and 3 months after operation by two independent investigators. We found patients received transcutaneous lower eyelid blepharoplasty with autologous fat graft had significantly higher global aesthetic improvement scale and Wrinkle Severity Rating Scale improvement than those underwent transcutaneous lower eyelid blepharoplasty only in each evaluation timepoints. There was no significant difference of adverse effects between both surgical methods. The present study demonstrated the efficacy and safety of the lower eyelid blepharoplasty with micro-autologous fat transplantation harvesting from resected orbital fat pads.

Platelet-Rich Plasma Versus Platelet-Poor Plasma for Treating Facial Photoaging: a Double-Blind Randomized Controlled Splitting Face Study.

BACKGROUND: As the demand for non-invasive esthetic procedures to maintain a youthful appearance increases, there has been growing interest in the use of autologous platelet-rich plasma (PRP) and platelet-poor plasma (PPP) for the treatment of facial aging. However, there are few studies directly comparing the efficacy of PRP and PPP for facial rejuvenation. OBJECTIVES: This study aimed to compare the efficacy of PRP and PPP for facial rejuvenation. METHODS: This single-center, double-blind, randomized controlled trial was conducted from January 1, 2022, to July 31, 2022, and included ten participants who completed the follow-up. The participants were randomly assigned to receive 2.5-mL injections of PRP and PPP on different sides of the face in three sessions with 1-month intervals. The outcome was primarily determined by blinded photographic assessments and secondly by scores of the VISIA® system during the follow-up. RESULTS: Both PRP and PPP treatments resulted in significant improvement in the Global Aesthetic Improvement Scales and Modified Fitzpatrick Wrinkle Scale for periocular Powered by Editorial Manager® and ProduXion Manager® from Aries Systems Corporation wrinkles, with no significant difference between the two groups. However, no improvement was observed in the Wrinkle Severity Rating Scales for nasolabial folds in either the PRP- or PPP-treated groups. Furthermore, no severe adverse events were reported. CONCLUSIONS: Both PRP and PPP are effective in treating facial photoaging. PRP exhibited slightly superior efficacy in enhancing overall skin condition, while PPP was slightly more effective in improving shallow wrinkles. This study provides valuable evidence for the use of PRP and PPP in facial rejuvenation procedures.

A structured approach with Swiss cheese model to reduce vascular adverse events of filler injections.

BACKGROUND: Filler injection is among the most popular nonsurgical aesthetic procedures worldwide. Though relatively noninvasive, filler injection can lead to severe vascular adverse events. Even though the incidence is rare, it may cause devastating and irreversible outcomes. A Swiss cheese model has been widely applied for risk analysis and management approach in medical field. AIMS: In this review article, we adopt the Swiss cheese model and create a structured approach to prevent severe vascular complications caused by filler injections. METHODS: We reviewed the current literature regarding the knowledge and techniques of preventing vascular adverse events in the filler injection. RESULTS: We propose four structured strategies in this model to reduce the risk of severe vascular adverse events of filler injections, including clinical facial anatomy, safe filler injection principles, real time imaging and auxiliary instruments, and implication of checklist. CONCLUSION: This review provides clinicians a structured approach before and during the filler injection procedure to reduce the risk of vascular adverse events and improve its safety and outcome.

A single session of high-energy microwave axillary hyperhidrosis and osmidrosis therapy: Key pretherapeutic assessment and outcome analysis.

BACKGROUND: Microwave therapy is used to treat axillary hyperhidrosis and osmidrosis. Even while a "danger zone" has been identified and reports of potential complications from nerve injury have been made, there has been little real-world discussion regarding whether there is any pretreatment evaluation key factor that may lower the risk. Furthermore, the efficacy of a single treatment and the safety of high-energy therapies have not been well investigated. OBJECTIVE: The aim of this study is to demonstrate the key aspects of pre-therapeutic assessment, efficacy, and suitability of a single treatment, as well as the safety of high-energy treatments. METHODS: Fifteen patients with axillary hyperhidrosis (AH) and axillary osmidrosis (AO) between ages of 20 and 50 had pretherapeutic ultrasonography and clinical assessments performed followed by a single-pass microwave treatment using the miraDry system at energy level 5. The severity of AH and AO was evaluated using the Hyperhidrosis Disease Severity Scale and Odor-10 scale, respectively, at baseline, 1 month, 3 months, and 1 year after treatment. Adverse reactions were recorded at each point of evaluation. RESULTS: Out of 30 treatment areas, 14 have a danger zone. Female gender, a small mid-upper arm circumference, and a low body mass index (BMI) are all associated risk factors. The average Hyperhidrosis Disease Severity Scale score decreased from 3.1 ± 0.7 to 1.3 ± 0.5 (p < 0.001), while the odor-10 score declined from 7.1 ± 1.6 to 3.0 ± 1.6 (p < 0.001), indicating a significant improvement in AH and AO. Most of the unfavorable treatment effects disappeared within the first month. LIMITATIONS: This study has no objective quantitative measurement of axillary odor severity and sweat assessment. CONCLUSION: Female patients, those with a smaller mid-upper arm circumference, and those with a low BMI should be treated with extra caution, and the tumescent anesthetic dose may be increased based on safety. A high-energy microwave treatment procedure performed in a single session is a safe and effective therapeutic option with good recovery.

Comprehensive Evaluation of the Lower Eyelid Aging Process Among Asian Women.

BACKGROUND: Lower eyelid aging is a complicated process, and for that reason, a comprehensive assessment of the lower eyelid is important before treatment. OBJECTIVE: This study was conducted to analyze and assess the lower eyelid aging process between different age groups of Asian women. METHODS AND MATERIALS: The authors developed the comprehensive lower eyelid age rating scale (CLEARS). The rating scale contains 3 domains and each composed of 3 items. Individuals were evaluated by the age group starting with the third decade (20-29 years) through the seventh decade (60-69 years) by 2 dermatologists working independently. RESULTS: A total of 114 cases were evaluated. The total scores of CLEARS increased significantly between each adjacent age group. The scores of the snap test and the severity of fine lines, nasojugal groove, midcheek furrow, and eye bags increased significantly from the 3rd decade. The scores of the distraction test and the severity of palpebromalar groove and malar mound begin to increase with the 4th decade. Kappa coefficients of all items achieved moderate to substantial agreement. CONCLUSION: This study describes the lower eyelid aging process among Asian women by CLEARS assessment. Lower eyelid aging becomes progressively more notable beginning with the third decade.

A retrospective review of transcutaneous and transconjunctival dual approach-A technique for mini-invasive double eyelid blepharoplasty with blepharoptosis correction.

BACKGROUND: Many Oriental eyes feature single eyelid fold and ptotic eyelid. Performing the double eyelid blepharoplasty (DEB) in a minimally invasive manner with simultaneous blepharoptosis correction (BPC) is important to achieve an aesthetic pleasing outcome. OBJECTIVE: To demonstrate an effective mini-invasive transcutaneous and transconjunctival dual approach technique for simultaneous DEB and BPC. Furthermore, to compare the outcome of BPC in dual approach, transcutaneous procedure and transconjunctival procedure. METHODS: This is a retrospective study reviewing 159 eyelids that underwent mini-invasive DEB with BPC from November 2018 to May 2019, including the technical description and the surgical outcomes. To investigate the efficacy, the pre- and postoperative margin reflex distance 1 (MRD1) and levator function (LF) corresponding to the different surgical procedures and preoperative severity was analyzed. RESULTS: Statistically, the dual approach group has significant improvement in MRD1 and LF (47 eyelids, p<0.05) corresponding to patients with ptosis of any severity. Under the same tucking amount, dual approach can achieve 1.6±0.7 mm of MRD1 improvement, which is nearly twice the amount compare with transconjunctival approach alone. No revision nor complication noted in the dual approach group by 6-month follow-up. CONCLUSION: The dual approach technique is a method with a wide range of applications, effective, and low revision rate that simultaneously correct blepharoptosis and create a double eyelid.

Efficacy and safety of the picosecond 755-nm alexandrite laser for treatment of dermal pigmentation in Asians-a retrospective study.

Q-Switched laser devices have been a standard treatment modality for dermal pigmentary disorders since the 1990s. However, the adverse events are sometimes intolerable even if the efficacy has been well accepted. These adverse events stop the patient from continuing the treatment and cause other cosmetic issues. Since 2012, the first picosecond laser for cosmetic applications was approved; it seems promising for treating pigmentary disorders in a new way, but lack strong evidence. We evaluated the efficacy and safety of a 755-nm picosecond laser for treatment of dermal pigmentary disorders in Asians. This is a 2-year retrospective study. We reviewed 36 female cases, including 8 cases of nevus of Ota and 28 cases of acquired bilateral nevus of Ota-like macules. Institutional Review Board (IRB) approval was granted by the Chang Gung Memorial Hospital medical research ethics committee (IRB 201900833B0). The epidemiologic data was collected. These patients have been treated with the 755-nm picosecond laser for 1 to 4 sessions at variable treatment interval. Our parameter settings were fluence of 2.73-3.98 J/cm2, with a spot size of 2.9 to 2.4 mm under the 650-ps mode. The pulse duration is 650 ps and fluence range is from 2.73 to 3.98 J/cm. Photographs were taken prior to every treatment and 1 month following the treatment. Two dermatologists conducted the clinical evaluation independently. Clinical improvement was observed in all with a minimal side effect. A total of 88.89% of patients had moderate to marked improvement in following 1 to 4 sessions. Transient swelling and erythema were observed in all patients but resolved within 24 h. Only one patient (2.78%) developed hypopigmentation and two patients (5.56%) had hyperpigmentation temporarily. Faster clearance could be achieved by the picosecond 755-nm laser for treating dermal pigmentary disorders in Asians. The treatment course is well tolerable and has minimal side effects.

A Prospective Study of Fractionated Dual-Wavelength Picosecond Laser in Treating Acne Scar.

BACKGROUND AND OBJECTIVES: The picosecond (PICO) laser has been a new and promising device. But, so far, there have not been many prospective studies investigating the efficacy in acne scar treatment. This study evaluated the efficacy and safety of the dual-wavelength picosecond laser in the treatment of acne scar. STUDY DESIGN/MATERIALS AND METHODS: A total of 20 patients with skin type III-IV were enrolled in this study. Eighteen patients completed the study. All patients completed six treatment sessions within a 1-month interval. All patients were treated using both 532 and 1,064 nm fractionated dual-wavelength picosecond handpieces. In evaluation, Goodman and Baron's quantitative global acne scarring grading system (GSS) was scored by two physicians. Patients also judged the results themselves by Visual Analog Scale (VAS) and pain score. RESULTS: The average baseline score of GSS quantity and quality were 15.22 and 3.00, respectively. The final scores were 10.61 and 2.33. The average baseline of patient VAS score was 4.28. The final score was 2.00. All scores achieved statistical significance (P < 0.05). No serious long-term side effects were recorded. CONCLUSION: Acne scar treatment with the fractionated dual-wavelength picosecond laser has shown both efficacy and safety in this study. Lasers Surg.

Harvested vs estimated follicular units in hair transplantation.

BACKGROUND: The follicular unit transplantation strip harvesting surgery is one of the gold standard methods of hair transplantation; the counting follicular unit ratio and hair density is a major step in donor site evaluation. AIMS: We conducted the study for analyzing the preoperative donor site evaluation and comparison of the actual harvested and estimated follicular units in hair transplantation. PATIENTS/METHODS: In this retrospective study, we enrolled 65 male patients with androgenetic alopecia who underwent follicular unit transplantation. Before the donor strip harvesting procedure, we counted the follicular unit density and calculated the percentage of each follicular unit. And then, we compared them to actual harvesting grafts. RESULT: The number of actual harvested transplanted hairs (3162.22 ± 958.30) were less than estimated transplanted hairs (3319.25 ± 1007.86). Both the number and percentage of actual harvested 1-hair follicular unit were more than estimated 1-hair follicular unit. In contrast, the number and percentage of actual harvested 3-hair follicular unit was less than estimated 3-hair follicular unit. The follicular unit density was lower in older patients. Those received more than one session of hair transplantation tended to have lower follicular and hair density (P = 0.007 and 0.01, respectively). The scalp laxity was lower in older patients and those received multiple sessions of hair transplantation. CONCLUSION: The actual harvested grafts yield more 1-hair follicular units and less 3-hair follicular units than estimation. Old age and multiple sessions of hair transplantation caused more limitation of harvesting donor scalp.

A split-face study: comparison of picosecond alexandrite laser and Q-switched Nd:YAG laser in the treatment of melasma in Asians.

To evaluate efficacy and safety of picosecond 755 nm alexandrite laser as compared to 1064 nm QS-Nd:YAG laser for melasma treatment in Asians. Twelve patients received 4 sessions of treatments at 1-month interval in a split-face manner. The right side of each patient's face received 755 nm picosecond laser, and the other side received 1064 nm QS-Nd:YAG laser. Zoom handpiece of 755 nm picosecond laser at fluence of 0.88-1.18 J/cm2 was applied. The treatment protocol used for 1064 nm QS-Nd:YAG laser was 8 mm spot size at fluence of 2.0 J/cm2 initially followed by 6 mm spot size at fluence of 3.5 J/cm2, and finishing with 4 mm spot size at 3.2 J/cm2. For both 755 nm picosecond laser and 1064 nm QS-Nd:YAG laser, the endpoint was mild erythema and swelling without petechiae. Objective evaluation with visual analogue score was conducted by two independent physicians. Subject self-assessment for each patient was conducted as well. Statistical results showed that higher pigmentation clearance rate was achieved at the 755 nm picosecond laser side after the second treatment. At the 3 months follow-up, greater clearance was observed at the 755 nm picosecond laser side compared to the 1064 nm QS-Nd:YAG side. 755 nm alexandrite picosecond laser has been observed to achieve a faster and better clearance rate for melasma compared to 1064 nm QS-Nd:YAG laser. We conclude that the 755 nm picosecond laser could be a safe and effective modality for melasma treatment in Asians.

Association of Varicose Veins With Incident Venous Thromboembolism and Peripheral Artery Disease.

Importance: Varicose veins are common but rarely associated with serious health risks. Deep venous thrombosis (DVT), pulmonary embolism (PE), and peripheral artery disease (PAD) are also vascular diseases but associated with serious systemic effects. Little is known about the association between varicose veins and the incidence of other vascular diseases including DVT, PE, and PAD. Objective: To investigate whether varicose veins are associated with an increased risk of DVT, PE, or PAD. Design, Setting, and Participants: A retrospective cohort study using claims data from Taiwan's National Health Insurance program. Patients aged 20 years and older with varicose veins were enrolled from January 1, 2001-December 31, 2013, and a control group of patients without varicose veins were matched by propensity score. Patients previously diagnosed with DVT, PE, or PAD were excluded. Follow-up ended December 31, 2014. Exposures: Presence of varicose veins. Main Outcomes and Measures: Incidence rates of DVT, PE, and PAD were assessed in people with and without varicose veins. Cox proportional hazards models were used to estimate relative hazards, with the control group as reference. Results: There were 212 984 patients in the varicose veins group (mean [SD] age, 54.5 [16.0] years; 69.3% women) and 212 984 in the control group (mean [SD] age, 54.3 [15.6] years; 70.3% women). The median follow-up duration was 7.5 years for DVT, 7.8 years for PE, and 7.3 years for PAD for patients with varicose veins, and for the control group, follow-up duration was 7.6 years for DVT, 7.7 years for PE, and 7.4 years for PAD. The varicose veins group had higher incidence rates than the control group for DVT (6.55 vs 1.23 per 1000 person-years [10 360 vs 1980 cases]; absolute risk difference [ARD], 5.32 [95% CI, 5.18-5.46]), for PE (0.48 for the varicose veins group vs 0.28 for the control group per 1000 person-years [793 vs 451 cases]; ARD, 0.20 [95% CI, 0.16-0.24]), and for PAD (10.73 for the varicose veins group vs 6.22 for the control group per 1000 person-years [16 615 vs 9709 cases]; ARD, 4.51 [95% CI, 4.31-4.71]). The hazard ratios for the varicose veins group compared with the control group were 5.30 (95% CI, 5.05-5.56) for DVT, 1.73 (95% CI, 1.54-1.94) for PE, and 1.72 (95% CI, 1.68-1.77) for PAD. Conclusions and Relevance: Among adults diagnosed with varicose veins, there was a significantly increased risk of incident DVT; the findings for PE and PAD are less clear due to the potential for confounding. Whether the association between varicose veins and DVT is causal or represents a common set of risk factors requires further research.

Pulsed alexandrite laser for treatment of melasma in Asian patients.

BACKGROUND: Melasma is a common acquired facial hypermelanosis with irregular brownish macules and patches. The clinical course is often fluctuated and refractory to treatment. The present study was conducted to evaluate the efficacy and safety of pulsed alexandrite laser for the treatment of melasma. MATERIALS AND METHODS: In the present study, we enrolled Asian patients with melasma. All the patients received four monthly treatments with a pulsed alexandrite laser. The severity of melasma was evaluated by a blinded dermatologist, using the Modified Melasma Area and Severity Index (MMASI), and by patient assessment, using a visual analogue scale, at baseline, before each treatment, and at the 1-month and 3-month follow-up visits after the last treatment. RESULTS: Twenty-three patients completed all treatments and follow-up visits. The MMASI scores decreased significantly from 8.71 ± 5.83 at baseline to 6.07 ± 4.65 after four sessions of treatment (P < 0.05) and 6.91 ± 4.97 at 3 months after the last laser treatment (P < 0.05). After 4 sessions of treatment, 10 patients (43.5%) described their improvement as marked and excellent (>60% improvement). The treatments were well tolerated with only mild skin reaction. CONCLUSION: In the present study, we demonstrated that the pulsed alexandrite laser is safe and effective to treat melasma in Asian skin.

Long-term follow-up for noninvasive body contouring treatment in Asians.

There are versatile modalities to achieve noninvasive fat reduction, and most of them have proven to be effective for circumferential reduction of local fat tissue, without any serious or permanent adverse effects. However, the follow-up time is short, ranging from 1 to 24 weeks. Most of the patients would like to know how long will its effect last and whether there is long-term side effect or not. The aim of this study was to assess the long-term efficacy and safety of combination therapy of focused ultrasound and radio frequency for noninvasive body contouring. Thirty-two Asian subjects received three sequential combination therapies of focused ultrasound and radio-frequency treatments every 2 weeks in the abdominal region and were followed up 1 month and 1 year after the last treatment. After a year, 5 patients were loss follow-up and 2 were pregnant. Finally, 25 healthy Asian subjects (18 females and 7 males) were enrolled in this study. Safety parameters and adverse events were recorded. The mean body weight change remained constant without a significant change 1 year after treatment and was 0.1 ± 1.2 kg (p = 0.513). The mean abdominal circumference change between 1 month and 1 year after the last treatment was 0.4 ± 1.2 cm and was not significant (p = 0.169). The relationships between weight change and circumference change of the 23 patients were tested using Spearman's rho correlation coefficient. There was a correlation between weight change and circumference change (0.73; p = 0.000). The procedure was safe without a recordable long-term adverse event. The combination therapies of nonthermally focused ultrasound and radio-frequency treatments for body contouring in the abdominal region are effective and may show positive results for at least a year if patients can maintain their body weight. The procedure is safe without recordable long-term adverse events in this study.

Treatment of melasma with mixed parameters of 1,064-nm Q-switched Nd:YAG laser toning and an enhanced effect of ultrasonic application of vitamin C: a split-face study.

Melasma is an acquired pigment disorder showing symmetrical hyperpigmentation of the face characterized by light to dark brown patches with indistinct borders on both cheeks. Melasma is prevalent in middle-aged women with harmless hormone imbalances. It is also known as the mask of pregnancy and is prevalent in most child-bearing women. It fluctuates month by month, and yet, there is no promising treatment. The Q-switched neodymium-doped yttrium aluminum garnet (QS-Nd:YAG) laser (1,064-nm wavelength) was introduced in Asia years ago for both skin toning and treatment of facial pigment. This low-fluence, 1,064-nm QS-Nd: YAG laser also reportedly improved melasma. Adjunctive treatments such as vitamin C iontophoresis or chemical peels were recommended in other reports. The technique using the 1,064-nm QS-Nd:YAG laser for toning and the enhancement of adjunctive treatments need further investigation and long-term follow-up before recommendations for the ideal protocol for melasma treatment can be made. The aim of this study is to evaluate the improvement of melasma using different parameters with the 1,064-nm QS-Nd:YAG laser with ultrasonic application of topical vitamin C. Eight patients, ranging in age from 32 to 45 years (mean 37 years), with long-term melasma were studied. Most of the melasma cases were dermal or mixed-type melasma. The patients had no cosmetic treatment (laser, intense pulsed light, or chemical peel) 1 year prior to the study. The entire face of each patient was treated with the 1,064-nm QS-Nd:YAG laser for four sessions at 1-month intervals. The laser treatment was divided into three parts with different parameters. First, each patient underwent whole face exposure for one pass with an 8-mm spot size at a power of 2.0 J/cm(2). Next, the spot size was shifted to 6 mm at a power of 3.5 J/cm(2) for one full-face pass, and then ended with a 4-mm spot size at 3.2 J/cm(2) for one full-face pass, with multiple passes for the main lesions. The end point was mild erythema and swelling, without petechiae. All patients applied ice packs for 5 min before the adjunctive treatment. We designed a split-face study with or without ultrasonic application of topical vitamin C. Only the right side of the face received ultrasonic melasma application of vitamin C for 15 min after ice packing. The left side of the face was covered with a moisturizing lotion. Objective evaluation was performed with visual analog score. All eight patients completed the 3-month follow-up after the four laser treatments. Statistics showed significant improvement with ultrasonic application of vitamin C compared to laser monotherapy. The improvement was more pronounced during second to fourth sessions. There was no rebound or post-inflammatory hyperpigmentation detected during the 3-month follow-up period. The combination of 1,064-nm QS-Nd:YAG laser treatment with ultrasonic application of topical vitamin C exerted more prompt response of melasma. We recommended this protocol including mixed parameters of 1,064-nm QS-Nd:YAG laser toning method combining with vitamin C ultrasonic application that can yield higher satisfaction for the difficult facial pigmentation problems such as melasma.
