RESUMO
BACKGROUND: Hyaluronic acid (HA) injection in the auricular base is one of the most popular and non-surgical cosmetic procedures for correcting lying ears and optimizing the facial profile because of its minimal invasiveness, immediate effect and safety (Li et al. in Aesthet Surg J 44: 746-75, 2024). But we have recently discovered that this treatment may lead to a new and rare complication called peripheral facial paralysis that has never been reported before. Until now, the etiology, clinical traits, treatment strategies, outcomes and possible reversibility have not been characterized. METHODS: In the present study, we enrolled 4 patients with peripheral facial paralysis after subcutaneous postauricular HA filler injection. Preoperative digital subtraction angiography revealed a vascular embolism. Then, the patients underwent super-selective facial arterial thrombolytic therapy via hyaluronidase and papaverine injections. Simultaneously, general symptomatic treatment and nutritional therapy were performed. RESULTS: The patients were relieved of their clinical symptoms and the significant improvement was observed in terms of motor function in her left facial areas after treatment. The auricular skin necrosis of all patients was restored to near normal appearance. CONCLUSION: Our results indicate that super-selective facial arterial thrombolytic therapy is feasible for patients with peripheral facial paralysis induced by HA embolism. It was also beneficial in the recovery from skin necrosis. The therapy was shown to be worthy of clinical application.

RESUMO
BACKGROUND: Laser and other energy devices have been widely used in the minimally invasive treatment of scars. Among various technologies, Fractional Micro-Plasma Radio Frequency Technology (FMRT) has gained extensive consensus in the treatment of various types of scars and skin disorders, such as wrinkles, skin laxity, and pigmentation. OBJECTIVE: This study is a retrospective clinical trial aimed at assessing the effectiveness and safety of FMRT for hypertrophic burn scars treatment in the Asian population under different anesthesia methods. METHODS: A total of 104 patients with hypertrophic burn scars treated in our department from May 2018 to May 2022 were selected. Scar assessment scales were applied to observe changes in scars before and after FMRT treatment. RESULTS: A prospective study of 104 patients found that female patients were more likely to undergo laser treatment under general anesthesia (P < 0.05). Postoperative VSS total score, VSS total score difference, and immediate postoperative pain score were all better with general anesthesia compared to local anesthesia (P < 0.05). There were more significant improvements in scar color, vascular distribution, and flexibility (P < 0.05). When comparing the treatment outcomes between females and males, it was found that general anesthesia patients were superior to local anesthesia patients in terms of color score, vascular distribution score, flexibility score, and postoperative VSS total score 6 months after the final treatment. General anesthesia patients had a shorter hospital stay. Overall treatment evaluation was better for female general anesthesia patients than male patients. CONCLUSION: General anesthesia combined with FMRT is an effective, safe, and more acceptable treatment method for hypertrophic burn scars in the Asian population. BULLET POINTS: In the Asian population, the combined use of general anesthesia and Fractional Micro-Plasma Radio Frequency Technology (FMRT) is an effective, safe, and accepted method for treating skin scars.

RESUMO
BACKGROUND: Arterial embolism is a rare complication caused by hyaluronic acid (HA) injection. However, it is one of the most serious complications. Once it happens, the complication would have a great and long-term impact on patients. Intra-arterial recanalization has been reported for recovering the visual acuity in patients with visual loss caused by hyaluronic acid. There is little report about the benefits of superselective intra-arterial recanalization therapy for skin wounds caused by hyaluronic acid vascular embolization. METHODS: Eight patients who had received the superselective intra-arterial recanalization therapy were retrospectively reviewed. Hyaluronidase was injected into the facial artery by superselective intra-arterial recanalization therapy, followed by symptomatic treatment. The facial artery recanalization was successfully performed and no interventional procedure-related adverse events happened. RESULTS: Arterial embolization accompanies by the interruption or reduction of blood supply, followed by ochrodermia, pain, numbness, swelling, yellowish white secreta and even necrosis on skin wound area. Early detection of skin blood supply disorders and early recovery of blood supply are very critical to treat facial artery embolization caused by HA. After superselective intra-arterial recanalization therapy, the blood supply to facial skin was restored and skin wounds recovered in all patients. Only 1 patient was left with small and superficial scars. CONCLUSION: Superselective intra-arterial recanalization therapy is an effective and safe method that can alleviate skin wounds caused by HA vascular embolization.

RESUMO
BACKGROUND: There are serious complications associated with hyaluronic acid (HA) facial injections, including vision impairment due to retinal artery ischemia. In this study, we put forth a clinically relevant model of retinal ischemia and reperfusion in rabbit. We used this to verify the efficacy of hyaluronidase intra-artery thrombolysis in the treatment of hyaluronic acid-induced retinal artery occlusion. METHODS: Retinal artery ischemia was induced by injecting HA into the ophthalmic artery (OA) of adult chinchilla rabbit, and reperfusion was achieved by intra-artery thrombolysis therapy with hyaluronidase following 60 min and 4 h of occlusion. Digital subtraction angiography (DSA) and fundus fluorescein angiography (FFA) were used to evaluate blood flow in the retina. Electroretinogram (ERG), hematoxylin and eosin staining and transmission electron microscope were used to evaluate the structure and function of the retina after ischemia and reperfusion following 60 min and 4 h of occlusion. RESULTS: DSA and FFA images confirmed occlusion of the ophthalmic and central retinal arteries, as well as reperfusion after hyaluronidase thrombolysis. ERG indicated retinal dysfunction following ischemia, and thrombolysis partially rescued its impairment following 4 h of occlusion. Hematoxylin and eosin staining and TUNEL staining revealed ischemia-induced histological damages in the retina at different time windows, and hyaluronidase thrombolysis partially mitigated these damages. CONCLUSIONS: We report a method to establish a HA-induced retinal artery occlusion animal model. Hyaluronidase intra-artery thrombolysis was used to recanalize the embolized OA at different time points. Using our method, we achieved retinal reperfusion, and an improvement was observed in the visual function of rabbits after hyaluronidase thrombolysis following 4 h of occlusion. We believe that hyaluronidase intra-artery thrombolysis is an effective method to treat HA-induced retinal artery occlusion in clinic.

BACKGROUND: Aesthetic injections have become increasingly popular for maintaining a youthful appearance. However, with the rise of SARS-CoV-2, there have been concerns about potential complications. This study aims to summarize and understand the complications that occur in individuals who have received cosmetic injections after SARS-CoV-2 infection or vaccination. By doing so, we hope to provide recommendations to minimize these complications and ensure the safety of aesthetic treatments in the current COVID-19 era. METHODS: The PRISMA guidelines, the Preferred Reporting Program for Systematic Reviews and Meta-Analyses, were used for this review. Databases including PubMed, EMBASE, Medline, Web of Science and ScienceDirect were searched. The last search time of each database was May 10, 2023. In addition, relevant references were manually searched. RESULTS: A total of 26 studies containing 139 patients were searched. The complication with the highest percentage of reported patients was delayed inflammatory response (DIR) (n = 68; 48.92%), followed by diminished efficacy (n = 45; 32.37%) and filler reaction (n = 12; 8.63%). The remaining complications include hypersensitivity reactions, symptomatic hypercalcemia, sub-acute hypersensitive reactions, hyperalgesia, infection, fat necrosis and granulomatous reaction. CONCLUSIONS: Cosmetic injectable procedures are generally safe but may have adverse effects, particularly during the pandemic. It is important for individuals to fully understand these risks beforehand. Clinicians should be knowledgeable about adverse event mechanisms and management to prevent issues. Industry leaders should strengthen risk management efforts to ensure safe and steady development of cosmetic injections. Overall, a comprehensive understanding, effective communication and risk management are crucial for the safe use of cosmetic injectable procedures.

BACKGROUND: Intravascular injection represents the most severe complication in fat transplantation procedures. Currently, the prognosis for patients who suffer from blindness due to fat transplantation-induced ocular vascular occlusion is far from optimistic. OBJECTIVES: The aim of this study was to explore and evaluate the efficacy and safety of arterial thrombolysis in the treatment of ocular vascular occlusion caused by fat transplantation. METHODS: We analyzed the data of 12 patients who underwent intraarterial thrombolysis and conservative treatments for facial autologous fat grafting-associated ocular vascular occlusion. Among the cases, there were 6 instances of ophthalmic artery embolism and 6 cases of central retinal artery occlusion. All patients suffered with sudden blindness, sometimes accompanied by eye pain, ptosis, strabismus, skin necrosis at the injection site, or cerebral microinfarction. They received symptomatic conservative treatments and intraarterial thrombolysis, encompassing mechanical vessel recanalization, vessel dilation, and dissolution of thrombus constituents. RESULTS: Following intraarterial thrombolysis, a noteworthy improvement in the blood flow of both the main trunk and peripheral branches of the ophthalmic artery was observed in the majority of patients when contrasted with their pretreatment status. One patient experienced a headache intraoperatively, while no significant discomfort was reported by the remaining patients. After conservative treatments and intraarterial thrombolysis, all patients experienced improvement in ocular symptoms, skin necrosis, and cerebral infarction. Three patients demonstrated improvement in visual acuity. These patients had surpassed the recommended time window for treatment, yet the occlusion of the ophthalmic artery was not complete. CONCLUSIONS: Intraarterial thrombolysis combined with conservative treatments achieves early perfusion and is expected to promote visual recovery. Hospitals that possess the necessary treatment capabilities are encouraged to establish this therapeutic pathway.

BACKGROUND: Hypertrophic scar (HTS) is a prevalent chronic inflammatory skin disorder characterized by abnormal proliferation and extracellular matrix deposition and the precise mechanisms underlying HTS remain elusive. This study aimed to identify and validate potential immune-related genes associated with hypertrophic scar formation. METHODS: Skin samples from normal (n = 12) and hypertrophic scar tissues (n = 12) were subjected to RNA-seq analysis. Differentially expressed genes (DEGs) and significant modular genes in Weighted gene Co-expression Network Analysis (WGCNA) were identified. Subsequently, functional enrichment analysis was performed on the intersecting genes. Additionally, eight immune-related genes were matched from the ImmPort database. Validation of NRG1 and CRLF1 was carried out using an external cohort (GSE136906). Furthermore, the association between these two genes and immune cells was assessed by Spearman correlation analysis. Finally, RNA was extracted from normal and hypertrophic scar samples, and RT-qPCR, Immunohistochemistry staining and Western Blot were employed to validate the expression of characteristic genes. RESULTS: A total of 940 DEGs were identified between HTS and normal samples, and 288 key module genes were uncovered via WGCNA. Enrichment analysis in key module revealed involvement in many immune-related pathways, such as Th17 cell differentiation, antigen processing and presentation and B cell receptor signaling pathway. The eight immune-related genes (IFI30, NR2F2, NRG1, ESM1, NFATC2, CRLF1, COLEC12 and IL6) were identified by matching from the ImmPort database. Notably, we observed that activated mast cell positively correlated with CRLF1 expression, while CD8 T cells exhibited a positive correlation with NRG1. The expression of NRG1 and CRLF1 was further validated in clinical samples. CONCLUSION: In this study, two key immune-related genes (CRLF1 and NRG1) were identified as characteristic genes associated with HTS. These findings provide valuable insights into the immune-related mechanisms underlying hypertrophic scar formation.

BACKGROUND: While micro-plasma radiofrequency (MPR) treatment has a significant impact on hypertrophic scars, patients often require anesthesia to alleviate substantial discomfort. Currently, patients with similar degrees of scarring may choose surface anesthesia or general anesthesia based on their personal preferences. Nevertheless, the effectiveness and safety of different anesthesia modalities remain uncertain. OBJECTIVE: To assess the effectiveness and safety of both general and surface anesthesia in MPR treatment for hypertrophic scars. METHODS: We conducted a retrospective cohort study involving 101 patients diagnosed with hypertrophic scars who underwent MPR with different anesthesia methods. The primary measures of efficacy included the Vancouver Scar Scale (VSS) scores assessed before the first treatment and six months after the final treatment. Pain relief was evaluated using Visual Analog Scale (VAS) scores. Safety was assessed by comparing the incidence of adverse reactions between the two groups. RESULTS: Patients in the general anesthesia group showed a significant difference in scar pigmentation 6 months after the treatment and lower pain level than those in the surface anesthesia group in the treatment of MPR. The difference in safety was not statistically significant. After adjusting for confounding factors and propensity score matching, the outcome of VSS and VAS scores was stable. CONCLUSION: General anesthesia, as opposed to surface anesthesia, appears to enhance both the effectiveness and safety of MPR while reducing postoperative pain in the treatment of hypertrophic scars. For patients with heightened pain sensitivity, general anesthesia may be the preferred treatment option.

BACKGROUND: Hyaluronic acid (HA) filler-induced vascular embolism that threatens skin integrity is an urgent situation. There is increasing evidence that percutaneous intra-arterial hyaluronidase injection is an effective therapeutic technique for it. However, until now, there is a lack of a unifying protocol about the technique. OBJECTIVES: This study aims to provide a conclusion of percutaneous intra-arterial hyaluronidase injection along with adjunctive measures on the treatment of occlusions precipitated by HA-based filler and develop a stepwise treatment protocol. METHODS: We searched PubMed for peer-reviewed studies, consensus statements, case series, and case reports using a variety of keywords. RESULTS: High-dose, pulsed hyaluronidase is the mainstay for the treatment of HA filler-induced embolism, but percutaneous intra-arterial hyaluronidase injection is a more effective technique. Until now, hyaluronidase is injected into three arteries percutaneously, including facial artery, supratrochlear artery, and superficial temporal artery. Furthermore, the adjunctive measures that may optimize clearance of an occlusion and/or skin barrier repair such as the use of image guidance and CGF should be considered. CONCLUSION: Vascular occlusions that threaten skin integrity are an urgent matter which requires accurate diagnosis and effective intervention. Percutaneous intra-arterial hyaluronidase injection along with adjunctive measures performed in a stepwise manner is key to an optimal outcome.

BACKGROUND: The increasing popularity of cosmetic injections using various fillers and neuromodulators for facial rejuvenation has brought both new opportunities and challenges to this field. AIM: Our study was designed to employ bibliometric and visual analysis for a qualitative and quantitative evaluation of facial cosmetic injections, as well as to identify research trends and hotspots in this field. METHODS: All publications covering facial cosmetic injection during 2002-2023 were retrieved and extracted from the Web of Science database. The VOSviewer 1.6.18 software and the online tool (http://bibliometric.com/) were applied to analyze the publication trend. RESULTS: A total of 3797 articles related to facial cosmetic injection were identified during the period 2002-2023. The United States had the largest volume of publications (1520, 40.0%), followed by China (333, 8.8%) and Germany (282, 7.3%). Among the institutions and journals, the University of California system and Plastic and Reconstructive Surgery accounted for the most papers related to facial cosmetic injection, respectively. Facial anatomy and injection techniques, prevention and management of complications, regenerative medicine, efficacy and safety of various soft-tissue fillers, as well as botulinum toxin injections for facial rejuvenation were identified as hotspots for facial cosmetic injections. CONCLUSIONS: Facial cosmetic injections are showing an increasing trend in terms of both the number of published papers and operations performed. Despite the notable advancements in this field, numerous challenges persist, including safety concerns and the level of research evidence. With the emergence of novel technologies and materials, scholars from diverse countries and institutions should engage in more extensive collaboration, thereby directly expediting the progress of this field.

BACKGROUND: Rhinoplasty is becoming increasingly frequent as the pursuit of aesthetics by people accelerates. In recent years, the proportion of people opting for rhinoplasty injections has gradually increased. This has led to numerous reports citing catastrophic postoperative complications such as skin necrosis, cerebral infarction, and visual impairment. AIM: The aim of our report is to discuss the possible etiological factors for this post-rhinoplasty complication and provides a rationale for HA injection history as a risk factor in rhinoplasty. METHODS: We report a rare case that received nasal HA injections in the past without any untoward incident. She opted for a second rhinoplasty 2 years after her initial nasal HA injections. This second intervention led to post-injection loss of vision in one eye and cerebral infarction. Following clinical and radiological examination, digital subtraction angiography (DSA) and superselective intra-arterial thrombolysis were performed. RESULTS: The patient did not develop disuse exotropia or ocular atrophy, but the left eye remained without light perception, which implies that intra-arterial thrombolytic therapy may be a positive and effective method to maintain the normal appearance of the eye. CONCLUSION: It is advisable for patient safety to maintain a long interval of time between hyaluronidase injection and repeat rhinoplasty. Clinicians should become familiar with the anatomical peculiarities of the patient and be gentle during the rhinoplasty procedure.

BACKGROUND: Several cases of wounds caused by vascular compromise after facial cosmetic injection have been reported in recent years. How to promote wound healing, restore facial appearance, and avoid secondary injury in such patients have remained a clinical challenge. Our study was designed to assess the effect of concentrated growth factor (CGF) for repairing nasal wounds after nasal hyaluronic acid injection. METHODS: Six women with nasal wounds after hyaluronic acid injection were enrolled from June 2019 to June 2022. The average time of the first CGF treatment from admission was 2-4 days. CGF gel was prepared from each patient's blood by using a Medifuge™ system. After debridement of the wound, the prepared CGF gel was applied on the wound surface, and the wound dressing was fixed to stabilize the CGF gel. The CGF treatment interval was 3-4 days. RESULTS: The wound began to heal after the first CGF treatment. After 2-3 CGF treatments, the wound was almost completely healed. There was no deflection of the nasal columella, and nasal ventilation function was good. There was no obvious deformity in the appearance of the nose. After follow-up ranging from 2 months to 1 year, the appearance and function of the nose showed satisfactory recovery. CONCLUSIONS: CGF has great potential in promoting wound healing and restoring the appearance after complications from nasal hyaluronic acid injection. The preparation of CGF gel is simple, and the clinical application is convenient and safe. In future, more clinical trials are needed to further prove the efficacy and safety of CGF in the treatment of wounds secondary to cosmetic injection.

BACKGROUND: Injection lipolysis is used for body and face contouring due to its minimal invasiveness and cost-effectiveness, but related complications such as nontuberculous mycobacterium infection significantly affect its clinical application. AIMS: This study aimed to review the literature on NTM infection after injection lipolysis. METHODS: We conducted a literature review of scientific journals published in Medline and PubMed up to September 2022 on patients with NTM skin and soft tissue infections. We used the keywords: nontuberculous mycobacterium, infection, injection lipolysis, and lipolytic solution in various combinations with the Boolean operators AND, OR, and NOT. Only articles available in English and full version publications were considered for this review. Here, we reviewed the relevant mechanisms and drugs for injectable lipolysis and analyzed the possible correlation between NTM infection and injection lipolysis. We also summarize methods for the diagnosis and treatment of NTM infections and present some perspectives on this therapy. RESULTS: Many patients with NTM infections had a history of fat-related surgery or therapy. NTM infection after injection lipolysis may be related to inadequate disinfection and sterilization of injection equipment and clinical procedures, the unqualified medication itself and free fatty acids released during injection lipolysis. Currently, diagnosis and treatment of NTM infection after lipolysis injections remains challenging. CONCLUSIONS: Injection lipolysis represents a helpful option for local fat reduction. Doctors should strictly abide by the aseptic operation standards and use qualified products for there is a correlation between skin and soft tissue infection of nontuberculous mycobacterium and injection lipolysis. Providers should understand the mechanism, indications, and associated risks of injection lipolysis when injecting fat-dissolving drugs to reduce localized fat.

BACKGROUND: Necrosis of frontotemporal skin and/or the ipsilateral scalp with subsequent alopecia after hyaluronic acid (HA) filler injection into the temple is rare complications with superficial temporal artery embolization are suspected as the major pathological mechanism. The main treatment currently is intralesional hyaluronidase (HAase) injection, but the effectiveness of percutaneous superficial temporal arterial HAase injection still lacks consensus. OBJECTIVES: To investigate the effectiveness of superficial temporal arterial HAase injection in dissolving HA filler-induced necrosis of frontotemporal skin and/or the ipsilateral scalp with subsequent alopecia. METHODS: Five recent clinical cases with necrosis of frontotemporal skin and/or the ipsilateral scalp with subsequent alopecia after HA filler injection into the temple were analyzed retrospectively. The patients underwent HAase injection via superficial temporal artery combined with adjunctive treatments, and the clinical progress was observed. RESULTS: Significant improvement was observed in terms of necrosis of frontotemporal skin and the ipsilateral scalp after treatment, and the patients were relieved of their clinical symptoms. Alopecia occurred approximately 1 to 2 weeks after HA filler injection, and the well-defined alopecia areas were formed 15 to 20 days after HAase injection. Patients were followed for 3 to 6 months. During follow-up, the skin lesions of all patients were restored to near normal appearance. Hair regrowth was observed 2 to 3 months after HAase treatment, and hair density nearly reached the normal level 3 to 4 months later. CONCLUSIONS: Percutaneous superficial temporal arterial HAase injection is an effective treatment option for HA filler-induced necrosis of frontotemporal skin and/or the ipsilateral scalp with subsequent alopecia.

As a consequence of the current trend of performing minimally invasive surgery, the use of injectable fillers has progressively increased in aesthetic surgery. Vascular complications resulting due to the filling of hyaluronic acid (HA) in the chin have been previously reported. However, clinical evidence regarding the results of treatment of lingual artery occlusion with super-selective intra-arterial dissolution is lacking. Herein, we reported a case of lingual artery occlusion resulting due to HA filling for which tongue arteriography and catheter-directed dissolution were implemented via femoral artery intubation for the first time in the literature. The aim of this paper was to discuss the rare complications arising due to chin augmentation and their treatment to provide a deeper understanding of the use and side effects of HA in this procedure.

BACKGROUND: Cosmetic filler injection can cause a variety of eye complications; however, there is currently no good way to evaluate injury severity and prognosis. By analyzing the injury manifestations of severe ocular complications following cosmetic filler injection and their prognosis, we propose a new injury severity scale. METHODS: Twenty-two eyes of 22 patients experiencing ocular complications following cosmetic filler injection were followed for 6 months to observe injury characteristics, manifestations and prognosis. Best corrected visual acuity (BCVA), intraocular pressure (IOP), split lamp microscopy, fundus photography, optical coherence tomography (OCT), and fundus fluorescein angiography were examined at the onset and follow-up visits. RESULTS: According to the immediate BCVA at the time of injury (with the presence or absence of brain infarction), a new injury severity scale was proposed, namely, Grades 1-4. Grade 1 (4 patients) and Grade 2 (2 patients) tended to have no atrophy of the globe. Grade 3 (12 patients) and Grade 4 (4 patients) were more likely to develop atrophy of the globe (4/12 patients and 2/4 patients, respectively) at the last follow-up. Grade 3 and Grade 4 were more likely to be complicated with ophthalmoplegia and ptosis (7/16 patients). CONCLUSIONS: The new injury severity scale we proposed can determine the prognosis of different ocular complications following cosmetic filler injection. Accordingly, we can inform injured patients regarding the possibility of phthisis bulbi and the extent of improvement of visual impairment, ophthalmoplegia, ptosis and stroke.

BACKGROUND: Vascular embolism is a serious complication of hyaluronic acid (HA) filler cosmetic injection, and hyaluronidase injection has been proposed as the treatment. Until now, there has been a lack of adequate clinical evidence regarding the benefits of treatment for HA filler-induced vascular embolism by percutaneous facial or supratrochlear arterial hyaluronidase injection. OBJECTIVES: The authors sough to evaluate the efficacy of percutaneous facial or supratrochlear arterial hyaluronidase injection as a rescue treatment for HA filler-induced vascular embolism. METHODS: We included 17 patients with vascular embolism after facial HA filler injection. Intraarterial injection of 1500 units hyaluronidase was performed via facial artery for 13 cases with skin necrosis and via supratrochlear arterial for 4 cases with severe ptosis and skin necrosis but no visual impairment. Simultaneously, general symptomatic treatment and nutritional therapy were performed. RESULTS: After hyaluronidase injection, facial skin necrosis in all cases was restored and ptosis in the 4 cases was also significantly relieved. Patients were subsequently followed-up for 1 month to 1 year. The skin necrosis in 16 patients completely healed, and only 1 patient had small superficial scars. CONCLUSIONS: It is effective to alleviate skin necrosis and ptosis resulting from HA filler embolism via percutaneous facial or supratrochlear arterial hyaluronidase injection.

BACKGROUND: The incidence of hyaluronic acid (HA) embolism has increased markedly in recent years. HA embolism can lead to serious complications such as blindness, eye and eyelid movement disorders, skin necrosis, and cerebral embolism. However, there is a lack of robust clinical evidence regarding the benefits of treatment of HA embolism with intra-arterial thrombolytic therapy (IATT). METHODS: In the present study, we enrolled 45 patients with decreased visual acuity, including 40 patients with symptoms of vision loss and eight patients with symptoms of intracranial embolism. The patients underwent emergency IATT via hyaluronidase and papaverine injections, followed by conventional sequential therapy. RESULTS: In the 45 patients with symptoms of vision loss, 16 (36%) exhibited improvements in final visual acuity, even when the clinical application of the thrombolytic treatments was performed beyond the recommended window for optimal treatment. The facial skin necrosis of all patients was restored to near normal appearance. Notably, for eight patients with suspected symptoms of intracranial infarction we performed cerebral angiography and IATT, and in two patients obtained partial recanalization of the obstruction, the symptoms of heavy headache and binocular distension pain were improved in one patient with intracranial embolism after IATT treatment. CONCLUSION: Our results indicate that IATT is feasible for patients with vision loss induced by HA embolism. IATT combined with conventional sequential therapy was beneficial in the recovery from other serious HA embolism complications. Nevertheless, the underlying pathophysiological mechanism needs to be clarified in future animal experiments.

BACKGROUND: With an increase in recent years in the number of people receiving cosmetic facial injection treatments of hyaluronic acid, the incidence of hyaluronic acid embolism has also increased commensurately. Hyaluronic acid embolism leads to serious complications, including blindness, eye and eyelid movement disorders, skin necrosis, and cerebral embolism. However, there is a lack of robust clinical evidence regarding the benefits of treatment for hyaluronic acid embolism by intraarterial thrombolysis therapy. METHODS: This study included 24 patients with a decrease in visual acuity and other complications induced by facial hyaluronic acid injection. Patients underwent emergency intraarterial thrombolysis therapy by injection of hyaluronidase (500 to 1500 units) alone or hyaluronidase (750 to 1500 units) combined with urokinase (100,000 to 250,000 units), followed in both cases by a general symptomatic treatment and nutritional therapy. RESULTS: Ten (42 percent) of 24 patients ultimately had improvements to visual acuity, even when the clinical application of the thrombolytic treatments had passed the recommended window for optimal treatment. In all cases, patients' facial skin necrosis was restored to nearly normal appearance. In addition, the authors found that hyaluronidase combined with urokinase was a more effective therapy than hyaluronidase alone. CONCLUSIONS: The authors' results indicate that intraarterial thrombolysis therapy is beneficial to patients suffering from blindness induced by hyaluronic acid embolism. The therapy was shown to be worthy of clinical application because it alleviated the impairment to patients' vision and was also beneficial in the recovery from other serious complications, including eye movement disorder, eye edema, headaches, and skin necrosis. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

BACKGROUND: Chyle fat transplantation has shown positive effects on preexisting human hypertrophic scars (HSs) in a nude mouse HS graft model. METHODS: Hypertrophic scar fragments were obtained from 5 surgically treated burn patients and implanted into the backs of nude mice in 3 groups: group A, control; group B, triamcinolone; and group C, chyle fat. The specimens were implanted after the corresponding intralesional injection in each group, and the mice were observed for 4 weeks. In total, 18 mice and 72 scar specimens were studied. After 4 weeks, the HSs were removed from the mice. Then, the scar weights, histology, and decorin staining were assessed to evaluate the therapeutic efficacy. RESULTS: An obviously significant difference was observed in the HS weight reduction between groups A and C (P < 0.01), and a significant difference in the HS weight reduction was observed between groups A and B (P < 0.05). However, there was no significant difference between groups B and C. The treatment groups (groups B and C) showed strong decorin staining. Furthermore, the decorin staining was much stronger in group C than in group B (P < 0.05). Significant differences in extracellular matrix deposition were observed among the 3 groups, as determined by Masson trichrome staining. Both groups B and C showed significant therapeutic efficacy compared with group A, and group C exhibited a significant therapeutic effect compared with group B (P < 0.05). CONCLUSIONS: This study indicates that chyle fat grafting is beneficial for treating HSs.
