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.This study aimed to review the literature on NTM infection after injection lipolysis.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.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.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.

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 Although micro-plasma radiofrequency (MPR) treatment has a significant effect on scars, patients require anesthesia to relieve the significant discomfort it produces. Whether anesthesia impacts efficacy is unclear. Objective To evaluate the effect of different anesthesia on MPR for hypertrophic scars. Methods A retrospective cohort study involving 101 people was conducted to investigate the effectiveness and safety of general and topical anesthetics for the treatment of MPR scars. The primary measures of outcome were the Vancouver Scar Scale (VSS) scores before the first treatment and six months after the last treatment, as well as the Visual Analogue Scale (VAS) scores on the day and the day after the final treatment. Results The differences in scar pigmentation, vascularity, and overall VSS scores were higher in the general anesthesia group than in the surface anesthesia group. Patients in the general anesthesia group had a lower pain level than those in the surface anesthesia group. After adjusting for confounding factors and propensity score matching, the outcome of VSS and VAS scores was stable. There was no statistical difference in the adverse effects and satisfaction between the two groups. Conclusion General anesthesia, as opposed to surface anesthesia, may not only ensure safety but also increase the effectiveness of MPR and lessen postoperative pain in the treatment of hypertrophic scars.

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.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.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).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 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.

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.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.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.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.Therapeutic, IV.
