ABSTRACT
Purpose: This randomized, controlled, blinded study evaluates the efficacy of intense pulsed light (IPL) therapy with low?level light therapy (LLLT) in the treatment of meibomian gland dysfunction (MGD) and evaporative dry eye (EDE) compared to a control group. Methods: Hundred patients with MGD and EDE were randomized into control (50 subjects, 100 eyes) and study group (50 subjects, 100 eyes). The study group underwent three sittings of IPL with LLLT 15 days apart and were followed up 1 month and 2 months after the last treatment sitting. The control group underwent sham treatment and was followed up at the same intervals. The patients were evaluated at baseline and 1 month and 3 months (post 1st treatment) for dry eye. Schirmer's test and tear breakup time (TBUT), OSDI, meibomian gland expression, and meibography. Results: The study group showed significant improvement in OSDI scores (P < 0.0001) compared to the control group and a significant improvement in TBUT (P < 0.005) compared to the control group. There was no change in schirmer's test and an improvement in the meibomian gland expression but not significant. Conclusion: The results show that a combined therapy of IPL with LLT is effective in treating MGD with EDE compared to controls, and repeated treatment sessions have a cumulative effect on the disease outcomes
ABSTRACT
This study reviewed the efficacy and safety of intense pulsed light (IPL) for the treatment of dry eye disease (DED). The PubMed database was used to conduct the literature search, which used the keywords “intense pulsed light” and “dry eye disease”. After the authors evaluated the articles for relevancy, 49 articles were reviewed. In general, all treatment modalities were proven to be clinically effective in reducing dry eye (DE) signs and symptoms; however, the level of improvement and persistence of outcomes differed amongst them. Meta-analysis indicated significant improvement in the Ocular Surface Disease Index (OSDI) scores post-treatment with a standardized mean difference (SMD) = ?1.63; confidence interval (CI): ?2.42 to ?0.84. Moreover, a meta-analysis indicated a significant improvement in tear break-up time (TBUT) test values with SMD = 1.77; CI: 0.49 to 3.05. Research suggests that additive therapies, such as meibomian gland expression (MGX), sodium hyaluronate eye drops, heated eye mask, warm compress, lid hygiene, lid margin scrub, eyelid massage, antibiotic drops, cyclosporine drops, omega-3 supplements, steroid drops, and warm compresses along with IPL, have been found to work in tandem for greater effectiveness; however, in clinical practice, its feasibility and cost-effectiveness have to be taken into consideration. Current findings suggest that IPL therapy is suitable when lifestyle modifications such as reducing or eliminating the use of contact lenses, lubricating eye drops/gels, and warm compresses/eye masks fail to improve signs and symptoms of DE. Moreover, patients with compliance issues have been shown to benefit well as the effects of IPL therapy is sustained for over several months. DED is a multifactorial disorder, and IPL therapy has been found to be safe and efficient in reducing its signs and symptoms of meibomian gland dysfunction (MGD)-related DE. Although the treatment protocol varies among authors, current findings suggest that IPL has a positive effect on the signs and symptoms of MGD-related DE. However, patients in the early stages can benefit more from IPL therapy. Moreover, IPL has a better maintenance impact when used in conjunction with other traditional therapies. Further research is needed to assess cost-utility analysis for IPL.
ABSTRACT
OBJECTIVE@#To evaluate the effect of intense pulsed light (IPL) in the treatment of chronic hordeolum.@*METHODS@#Patients with chronic hordeolum who underwent IPL treatment were enrolled in this study. According to the severity of hordeolum, the patients were treated with IPL 3 to 5 times. Patients' satisfaction and visual analog scale scores for ocular discomfort symptoms before and after treatment were collected. The number, congestion, long diameter, short diameter and area of nodules were also recorded and measured. Finally, eyelid margin signs, meibum quality, meibomian gland expressibility, meibomian gland dropout, tear meniscus height, and corneal fluorescein staining were scored.@*RESULTS@#20 patients were enrolled in this study. The eyelid margins were congestive and swollen, with blunt rounding or irregularity. The meibum was cloudy or toothpaste-like. The meibomian gland expressibility, meibomian gland dropout and tear meniscus height were reduced. The cornea showed scattered fluorescein staining. After treatment, score of visual analog scale, congestion and size of nodules were significantly reduced. Eyelid margin signs, meibum quality, meibomian gland expressibility, tear meniscus height and corneal fluorescein staining scores were improved. Meibomian gland dropout had no significant change. No side effects occurred during treatment.@*CONCLUSIONS@#IPL is beneficial for the treatment of chronic hordeolum.

AIM: To observe the therapeutic effect of the diquafosol sodium combined with intense pulsed light(IPL)on meibomian gland dysfunction(MGD)dry eye after refractive surgery.METHODS:A total of 64 patients(128 eyes)with MGD dry eye diagnosed within 6mo after laser corneal refractive surgery in our hospital from March 2021 to December 2021 were selected. They were randomly divided into control group and experimental group. A total of 33 patients(66 eyes)in the control group were treated with sodium hyaluronate combined with IPL, and 31 patients(62 eyes)in the experimental group were treated with diquafosol sodium combined with IPL. Ocular symptom scores were performed before each IPL treatment in both groups to examine non-invasive tear breakup time(NIBUT), tear meniscus height, lipid layer grade of tear film, meibomian gland deletion rate and uncorrected visual acuity.RESULTS:After IPL treatment, ocular symptom scores and meibomian gland deletion rate score of two groups were decreased continuously. NIBUT, tear meniscus height and lipid layer grade of tear film were increased continuously, and there was no significant change in uncorrected visual acuity. NIBUT of patients in the experimental group was better than that in the control group before the third IPL treatment(6.24±0.27s vs. 5.51±0.24s, P=0.046).CONCLUSIONS:Both diquafosol sodium and sodium hyaluronate combined with IPL showed good therapeutic effect on MGD dry eye, but there was no significant difference in the short-term efficacy between the two groups.
ABSTRACT
AIM: To systematically evaluate the efficacy of intense pulsed light(IPL)combined with meibomian gland expression(MGX)in the treatment of meibomian gland dysfunction(MGD)-related dry eye disease(DED).METHODS: Chinese and English databases such as Chinese national knowledge infrastructure(CNKI), Wanfang, VIP, CBM, ClinicalTrials, PubMed, Embase and Web of Science were searched, and clinical randomized controlled trials(RCTs)using IPL combined with MGX in the experimental group and MGX alone in the control group from January 2017 to September 2022 were included. Six outcome indicators including clinical efficacy, ocular surface disease index(OSDI)score, break-up time(BUT), corneal fluorescein staining(CFS)score, tear meniscus height(TMH)and meibomian gland yielding secretion score(MGYSS)were Meta analyzed by Review Manager 5.3 and Stata 14 software.RESULTS: A total of 15 RCTs were included, with 1 345 patients with MGD-related dry eye. Meta-analysis results showed that the treatment of MGD-related dry eye in the experimental group improved better clinical efficacy(OR=4.95, 95%CI: 2.76～8.90, Z=5.35, P&#x003C;0.00001), BUT(SMD=1.26, 95%CI: 0.84～1.69, Z=5.78, P&#x003C;0.00001), TMH(SMD=0.37, 95%CI: 0.15～0.59, Z=3.33, P=0.0009), and reduced OSDI scores(SMD=-0.86, 95%CI: -1.44～-0.27, Z=2.85, P=0.004)as well as MGYSS(SMD=-2.43, 95%CI: -4.31～-0.54, Z=2.52, P=0.01)than the control group. However, there was no statistically significant difference in CFS scores(SMD=-0.19, 95%CI: -0.46～0.07, Z=1.43, P=0.15).CONCLUSION: IPL combined with MGX in the treatment of MGD related dry eye can increase the overall effective rate and improve the symptoms and signs of patients with MGD related dry eye better than MGX alone.
ABSTRACT
AIM:To investigate the effect of 3% diquafosol sodium eye drops combined with intense pulsed light on the treatment of meibomian gland dysfunction and the change of meibomian glands.METHODS: Prospective study. A total of 141 patients(282 eyes)who were diagnosed with meibomian gland dysfunction from January 2021 to May 2022 in our hospital were selected and they were randomly divided into the control group(73 cases, 146 eyes)and the observation group(68 cases, 136 eyes)according to random number table. The control group was given 0.3% sodium hyaluronate eye drops combined with intense pulsed light, and the observation group was treated with 3% diquafosol sodium eye drops combined with intense pulsed light. The subjective symptom score, physical sign score, non-invasive tear break-up time, tear meniscus height, lipid layer thickness, and meibomian gland density before and after the treatment were compared between the two groups at 2wk after the end of treatment.RESULTS: There were no differences in the subjective symptom score, physical sign score, non-invasive tear break-up time, tear meniscus height, lipid layer thickness, and meibomian gland density between the two groups of patients before treatment(P>0.05). After 2wk of treatment, the symptom scores and physical sign scores of patients in the two groups continued to decrease, non-invasive tear break-up time and lipid layer thickness continued to increase, and the meibomian gland density also increased. The tear meniscus height in the observation group increased, while the control group showed no significant changes. The observation group had better clinical indicators than the control group(P<0.05). No obvious complications were observed in all patients.CONCLUSION: The combination of diquafosol sodium eye drops and intense pulsed light is synergistic in the treatment of meibomian gland dysfunction, with significant therapeutic effects and improvement of meibomian gland repair, which is significantly superior to simple intense pulsed light therapy.
ABSTRACT
AIM:To explore the efficacy of intense pulsed light combined with meibomian gland massage and diquafosol eye drops in lipid deficiency dry eye disease and related cytokines.METHODS: A total of 511 patients(1 022 eyes)with lipid deficiency dry eye diagnosed in the ophthalmology clinic of our hospital from January to December 2021 were selected as the research objects. They were divided into two groups according to the patient's wishes: 294 cases(588 eyes)in the study group were treated with diquafosol sodium eye drops combined with intense pulsed light and meibomian gland massage, while 217 cases(434 eyes)in the control group were treated with artificial tears combined with intense pulsed light and meibomian gland massage. The levels of tear tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β)and lactoferrin(LF)before and after treatment were detected, the corneal fluorescein staining(CFS)score, tear film break-up time(BUT), and Schirmer Ⅰ(SⅠt)under no surface anesthesia, ocular surface disease index(OSDI)were compared, the correlation between TNF-α, IL-1β, LF levels and CFS, BUT, SⅠt, OSDI before treatment was analyzed, and the occurrence of adverse reactions was observed.RESULTS: There was no significant difference in preoperative OSDI, SⅠt, BUT, CFS and levels of TNF-α, IL-1β and LF between the two groups(P>0.05). The SⅠt, BUT, CFS and levels of TNF-α, IL-1β and LF in the study group at 3, 6 and 9wk after treatment were better than those of control group(P<0.05). There were no differences in OSDI score of both groups at 9wk after treatment(P>0.05). The TNF-α and IL-1β were negatively correlated with SⅠt and BUT, while they were positively correlated with CFS and OSDI; LF and SⅠt were positively correlated with SⅠt and BUT, while they were negatively correlated with CFS and OSDI(all P<0.01); The adverse reaction rate of the study group(5.78%)was significantly lower than that of the control group(11.52%; P<0.05).CONCLUSION: Intense pulsed light combined with meibomian gland massage and diquafosol sodium eye drops is effective and well tolerated in the treatment of lipid deficiency dry eye.
ABSTRACT
AIM: To investigate the efficacy and safety of frequency of intense pulsed light(IPL)in the treatment of meibomian gland dysfunction.METHODS: In this retrospective study, a total of 108 patients(216 eyes)with meibomian gland dysfunction admitted to our hospital from January 2021 to June 2022 were included. They were divided into two groups, with 54 cases(108 eyes)IPL group(energy density 13.0J/cm2, pulse width 6ms, delay time 50ms), and 54 cases(108 eyes)in advanced optimal pulsed technology(AOPT)group(energy density 10.0-16.0J/cm2, pulse width 7-4-4 ms in unequal-division mode). The clinical effects of the two groups were observed and compared, including ocular surface symptoms, corneal fluorescein staining score(FL), tear film lipid layer thickness(LLT), ocular surface disease index(OSDI)score, mean non-invasive tear film break-up time(NIBUTav)and first non-invasive tear film break-up time(NIBUTf), tear meniscus height, score of meibomian gland secretion and its secretion traits, and the incidence of adverse effects was also calculated.RESULTS: The effective rate of the AOPT group(106 eyes, 98.1%)was higher than that of the IPL group(90 eyes, 83.3%, P<0.05), as well as OSDI score, FL score, score of meibomian gland secretion and its secretion traits, LLT NIBUTav, NIBUTf and tear meniscus height(all P<0.001). However, the incidence of adverse effects of the AOPT group(18 eyes, 16.7%)was higher than that of the IPL group(4 eyes, 3.7%; P<0.05).CONCLUSION: With significant improvement in the ocular surface symptoms and function, AOPT has a better therapeutic effect on the treatment of meibomian gland dysfunction, but it has more adverse reactions. Therefore, optimal treatment plan should be fully selected in combination with the actual clinical situation.
ABSTRACT
AIM: To investigate the safety and efficacy of intense pulsed light in the treatment of severe chronic ocular graft-versus-host disease.METHODS: Prospective randomized controlled study. A total of 35 cases(35 eyes), who had a history of allogenic hematopoietic stem cell transplantation(allo-HSCT), admitted to the Affiliated Hospital of Xuzhou Medical University from January to September 2022 and were diagnosed by our hospital's hematology and ophthalmology departments with severe chronic ocular graft-versus-host disease(coGVHD)were selected. One eye was randomly selected for inclusion in the study if both eyes met the enrollment criteria, and the eye was selected if a single eye met the enrollment criteria. All patients were administrated with Dextran and Hypromellose eye drops 4 times a day and Cyclosporine eye drops twice a day. The experimental group was additionally treated with intense pulsed light, once every two weeks a week, for 4 times in total. The evaluation indicators were evaluated before treatment and 2wk, 1 and 2mo after treatment. The evaluation indicators include ocular surface disease index(OSDI)score, best corrected visual acuity(BCVA), intraocular pressure(IOP), tear meniscus height(TMH), non-invasive break-up time(NIBUT), conjunctival injection score(CIS), meibomian gland area proportion(MGAP), meibomian gland evaluation(MGE), cornea fluorescein staining(CFS), conjunctival lissamine green staining(CLGS), lid margin abnormality score(LMAS), and Schirmer's Ⅰ test(SⅠt).RESULTS: After treatment, OSDI score, TMH, NIBUT, BCVA, CFS, CLGS, and CIS improved in both groups compared with those before treatment(all P<0.05), with NIBUT, CFS and CLGS showing more significant improvements in the test group. In the control group, MGAP, MGE of the upper and lower eyelids and LMAS did not change significantly before and after treatment(P>0.05), while in the experimental group, MGAP of the lower eyelids, MGE of upper and lower eyelids and LMAS improved compared with those before treatment(P<0.05), except for MGAP of the upper eyelids, which did not differ from that before treatment(P>0.05). There was no difference in SⅠt and IOP between the two groups before and after treatment(P>0.05). Patients did not experience adverse reactions such as skin burns, redness and swelling in the treated area and eyelash loss during the follow-up period.CONCLUSION: Intense pulsed light is safe and effective in the treatment of severe coGVHD, which can significantly improve the symptoms and signs of patients and enhance the stability of tear film.

ABSTRACT
Objective:To evaluate the efficacy and patients＇ satisfaction of the intense pulse light (IPL) and M22-Resur Fx non-ablative fractional laser (NAFL) for the treatment of lateral static crow＇s feet.Methods:A prospective split-face, randomized, controlled study of 60 consecutive patients with lateral static crow＇s feet was performed. The patients aged 30 to 55 years, who were enrolled in the Department of Ophthalmology, Beijing Tongren Hospital, Capital Medical University from January 2018 to January 2020. The two sides of each patient＇s face were randomized to receive different treatment, and according to their treatment, the patients were divided into 3 groups with 20 cases each: Group A, in which 20 patients＇ one side face was treated with IPL, and other side was treated with NAFL; Group B, in which one side face was treated with IPL, and another side was treated with IPL immediately followed by NAFL; Group C, in which one side face was treated with NAFL, and another side was treated with IPL immediately followed by NAFL. The improvements including the water content of stratum corneum of skin and the patients＇ satisfaction, as well as the improvement of the lateral static crow＇s feet were evaluated.Results:The IPL plus NAFL combined treatment group and the NAFL treatment group showed the effective rate of the improvement for lateral static crow＇s feet of patients on days 60 and 90 was statistically significant ( P<0.05) compared with that before the treatment. And the improvement for lateral static crow＇s feet of patients on days 60 and 90 in combined treatment side was significantly different from either NAFL side ( P<0.05). 60 days and 90 days after treatment, the satisfaction of combined treatment side was significantly higher than that of either NAFL side or IPL side ( P<0.05). Conclusions:The treatment with an optimized IPL immediately followed by a NAFL is clinically superior to those with the NAFL or IPL alone for improving the lateral static crow＇s feet of patients. The satisfaction treated by NAFL combined with IPL is higher than using the NAFL or IPL alone.
ABSTRACT
Objective:To observe the efficacy of drug combined with red-blue light irradiation, chemical peeling by glycolic acid and intense pulsed light (IPL) in the treatment of moderate acne vulgaris.Methods:A total of 187 patients with moderate acne vulgaris were divided into five groups. There were 59 males and 128 females, aged from 16 to 29 years (21.79±2.52). In group A, patients were treated with oral medicines; the patients were treated with oral medicines combined with red-blue light irradiation, chemical peeling by glycolic acid and IPL respectively in group B, group C and group D. In group E, patients were treated with oral medicines combined with chemical peeling by glycolic acid and IPL. The number of different types of skin lesions (comedoes, papules, pustules) were compared between before and after treatment in five groups. The clinical effect of five treatment groups was evaluated by comparing regression rates of different types of skin lesions and total skin lesions and treatment efficiency.Results:All the patients with moderate acne vulgaris were brought into this study. The regression rates of comedoes, papules and total skin lesions were (86.37±9.64)%, (94.25±9.79)% and (88.80±9.40)% respectively in group E, and significantly higher than that of other four groups ( P<0.05). The treatment efficiency of group E also were significantly higher than that of other four groups ( P<0.05). Then, the regression rates of comedoes (70.91±18.52) in group C was significantly higher than that of group A and group B ( P<0.05). The regression rates of papules (91.42±13.86) in group D was significantly higher than that of group A and group B ( P<0.05). Conclusions:Oral medicines combined with chemical peeling by glycolic acid and IPL has obvious clinical efficacy in treatment of patients with moderate acne vulgaris. Oral medicines combined with chemical peeling by glycolic acid can obviously improve comedoes, and oral medicines combined with IPL can obviously improve papules.
ABSTRACT
As lesões vasculares congênitas podem ser divididas em: tumores e malformações. Os hemangiomas são tumores vasculares benignos decorrentes da proliferação anormal de células endoteliais; já as manchas em vinho do Porto são malformações vasculares de provável herança autossômica dominante. Até o presente momento, não há estudos sobre a associação entre luz intensa pulsada e laser de CO2 como forma terapêutica destas patologias. A presente série de casos apresenta 10 casos de lesões vasculares tratadas com a combinação destas formas de irradiação. Conclui-se que esta terapia combinada pode ser efetiva na redução da espessura das lesões ou na atenuação da coloração
Congenital vascular lesions can be subdivided into tumors and malformations. Hemangiomas are benign vascular tumors resulting from the abnormal proliferation of endothelial cells, whereas port-wine stains are vascular malformations of a possible autosomal dominant inheritance. To date, there are no studies associating the use of intense pulsed light and CO2 laser as a therapeutic form for these pathologies. We present a series of 10 cases of vascular injuries treated with the combination of these forms of irradiation. This combined therapy can be effective in reducing the thickness of the lesions or in attenuating the color.
ABSTRACT
A ocronose exógena é um quadro de hiperpigmentação cutânea por acúmulo de substâncias derivadas de fenol na pele ou mucosas, sem acometimento de outros tecidos. Ocorre, principalmente, por uso de clareadores, sendo mais frequente a hidroquinona como despigmentante. As lesões apresentam difícil tratamento, sendo resistentes a diversas abordagens. Por vezes, é necessário utilizar tecnologias com laser ou luz intensa pulsada para atingir algum grau de melhora. O presente trabalho realizou revisão de literatura entre janeiro de 1990 e julho de 2020, organizando publicações acerca do uso destas tecnologias na ocronose exógena
Exogenous ochronosis is a cutaneous hyperpigmentation condition caused by the accumulation of substances derived from phenol on the skin or mucous membranes without affecting other tissues. It occurs mainly due to the use of bleaching agents, most frequently hydroquinone. The lesions are difficult to treat, being resistant to several approaches. Sometimes it's necessary to use laser technologies or intense pulsed light to achieve some degree of improvement. The present work consists of a literature review of publications on these technologies in exogenous ochronosis from January 1990 to July 2020.
ABSTRACT
This article introduces the safety risks of the novel light-based home-use hair removal device, and analyzes the differences in regulation among China, the United States and the European Union. In China, household intense pulsed light hair removal devices will also be supervised in accordance with medical device regulations. Therefore, the safety standards adopted in the absence of specific regulations are no longer applicable to the new regulatory requirements. It is imperative to adopt the new standards available to home photoepilators, so as to ensure the safety and effectiveness of the approved devices.

ABSTRACT
@#AIM: To compare short-term effectiveness of E-eye IPL combined with meibomian gland expression to simple meibomian gland expression in the treatment of meibomian gland dysfunction(MGD).<p>METHODS: Totally 40 patients with MGD(80 eyes)visiting the Department of Ophthalmology of West China Hospital of Sichuan University from October 2019 to January 2020 were randomly divided into experimental group and control group. Both eyes in the experimental group received IPL combined with meibomian gland expression, while those in the control group received meibomian gland expression only once every 2wk for 3 times. During the whole treatment, patients in the two groups received 0.3% sodium hyaluronate 4 times a day. Metrics were collected before each treatment and 2wk after the last treatment to evaluate the short-term efficacy of IPL combined with meibomian gland expression.<p>RESULTS: OSDI and SPEED scores of the two groups decreased with statistical significance(<i>P</i><0.05), but there was no statistical significance between the two groups(<i>P</i>>0.05). MGE and LLT of both groups increased. The increase in the control group was slower than that in the experimental group. MGE of the experimental group was higher than that of the control group after the second and third treatment, with statistical significance(<i>P</i><0.05). BUT of both groups increased. Corneal staining in both groups decreased, and it decreased more in the experimental group than in the control group, with no statistical significance between the two groups(<i>P</i>>0.05). The visual quality in the two groups improved, but in improving visual quality the experimental group was much better than the control group(<i>P</i>>0.05). There was no significant change in tear secretion, incomplete blink ratio and meibomian gland loss rate in the two groups(<i>P</i>>0.05). There were no skin and visual impairment, intraocular pressure change, anterior segment inflammation and other complications in all subjects.<p>CONCLUSION:IPL combined with meibomian gland expression and meibomian gland expression alone are both safe and effective. IPL, which has good, rapid effects and cumulative effects, works better after reaching a certain number of treatments.
ABSTRACT
A necrobiose lipoídica (NL) é uma dermatose granulomatosa, que acomete principalmente diabéticos devido à degeneração do colágeno. Embora existam diferentes tratamentos, todos apresentam pouca resposta. Dentre as opções, a luz intensa pulsada (LIP) e o laser Erbium-YAG permitem aumentar a produção e remodelamento do colágeno tratando a atrofia, além de diminuir o eritema pela coagulação de vasos sanguíneos. Relata-se caso de mulher, 24 anos, com diabetes mellitus tipo I, submetida a tratamento de NL no antebraço esquerdo em sete sessões com a associação entre LIP e laser Erbium-YAG 2940nm. Observou-se melhora da atrofia central e do eritema.
Necrobiosis Lipoidica (NL) is a granulomatous dermatosis, mainly affecting people with diabetes due to collagen degeneration. Although there are different treatments, all have little response. Among the options, the Intense Pulsed Light (IPL) and the Laser Erbium-YAG enhance the production and remodeling of the collagen treating the atrophy, besides reducing the erythema by the coagulation of blood vessels. We report a case of a 24-year-old woman with type I Diabetes Mellitus who underwent NL treatment on her left forearm in seven sessions with the association of IPL and 2940 nm Erbium-YAG laser. We observed improvement in central atrophy and erythema
ABSTRACT
O lentigo solar está presente em 90% da população com mais de 50 anos de idade, apresentando-se como manchas hipercrômicas em regiões fotoexpostas, que aumentam com o envelhecimento e são mais frequentes em peles claras. Há diversas modalidades terapêuticas com melhores resultados quando associadas. Descrevemos o caso de um homem de 62 anos, fototipo II de Fitzpatrick, com queixa de máculas acastanhadas em dorso nasal há oito anos. Foi submetido à biópsia de pele, e o estudo histológico confirmou ser lentigo solar. O paciente foi tratado com seis sessões de luz intensa pulsada associada a laser de Erbium: YAG 2940nm, com bom resultado clínico

ABSTRACT
A microstomia ocorre em 70% dos pacientes com esclerose sistêmica e há poucas opções terapêuticas. Descrevemos caso de mulher de 39 anos com diagnóstico de esclerose sistêmica em 2010, em uso de micofenolato de mofetil e rituximabe, apresentando microstomia. Foram realizadas duas sessões de luz intensa pulsada e sete sessões de laser fracionado ablativo Erbium:YAG de 2940nm, com resposta clínica importante. A formação e reorganização de fibras colágenas e elásticas foram responsáveis pela melhora da microstomia. Há poucos estudos com o uso de tecnologias para a abordagem da microstomia. Este é o primeiro com Er:YAG 2940nm para esta finalidade
Facial surgeries are often challenging for surgeons due to their complex anatomy, aesthetic and functional importance. Interventions in the cosmetic subunit that comprises the eyebrows can be particularly difficult. This case report aims to demonstrate the use of island flap in this region. We performed the excision of melanocytic nevus, with a good outcome and absence of postoperative complications. This technique is commonly used for facial reconstruction; however, the literature describes only a few cases using this method for eyebrow reconstruction.
