Background The injection of botulinum toxin into the masseter muscle is an important method for improving hypertrophy. However, some patients may experience adverse reactions, such as sagging of the lower jaw. Therefore, we proposed a method of injecting botulinum toxin into the masseter and platysma muscles that would reduce masseter size and enhance the jawline. Objectives The aim of this study was to reduce the masseter size while enhancing the jawline. Methods Twenty patients received botulinum toxin injections into the masseter and platysma muscles. Pain levels were evaluated with the visual analog scale. All patients were photographed before and 6 months after treatment. Evaluations were performed based on standardized criteria. The lift index, reduction index, and symmetry index were performed to assess the degree of jawline elevation, masseter size reduction, and jawline symmetry before and after treatment. Results The mean visual analog scale score of the 20 patients was 2.80 (±1.24). The mean lift index score decreased from 4.93 (±0.34) to 4.53 (±0.37), P <.05. The mean reduction index score decreased from 3.13 (±0.27) to 2.74 (±0.27), P <.05. The mean symmetry index score changed from 0.0393 (±0.0296) to 0.0257 (±0.0246), P <.05. Conclusions Botulinum toxin injections into the masseter and platysma muscles through nerve block reduced the masseter size, elevated the jawline, and improved symmetry.

Background: The demand for mammaplasty has increased in recent years, and infection remains one of the common and serious post‐operative complications. In this study, we analyzed the pathogen distribution and antibiotic susceptibility of breast plastic surgery infections, and compared the differences in pathogenic species between surgical procedures. Methods: The number of each species was counted in the microbial samples of breast plastic surgery infections in Plastic Surgery Hospital of Chinese Academy of Medical Sciences from January 2011 to December 2021. The in vitro antibiotic sensitivity testing data were analyzed using WHONET 5.6 software. The surgical techniques, the period of infection, and other details were gathered in accordance with the clinical data. Results: There were a total of 42 cases included, and 43 different types of pathogenic bacteria, mostly gram‐positive bacteria, were found. CoNS (13/43) and Staphylococcus aureus (22/43) made up the majority. The most prevalent of the five Gram‐negative bacteria was Pseudomonas aeruginosa. Results of drug sensitivity tests indicate that S. aureus is highly sensitive to vancomycin, cotrimoxazole, and linezolid, whereas CoNS is highly sensitive to vancomycin, linezolid, and chloramphenicol. Both of these bacteria show high resistance to erythromycin and penicillin. Breast augmentation, breast reconstruction, and breast reduction surgery were the most frequently associated breast surgery procedures in this study with infections, with the highest number of infections occurring following breast augmentation with fat grafting, breast reduction surgery, and breast reconstruction with autologous tissue. Various breast plastic surgery procedures have different common pathogens of infection, but the most prevalent are CoNS and S. aureus. Additionally, the majority of the infections in this study were in the early stages. Conclusions: Gram‐positive bacteria were the predominant cause of breast plastic surgery infections, and the types of infection strains, the period of infection onset, and the antibiotic susceptibility of prevalent strains varied between breast plastic procedures.

Background: The high recurrence rate after nonsurgical treatment of keloid is a major challenge for clinicians. Although there are many existing treatment options, how to optimize and upgrade the existing options and make a reasonable combination of utilization is our concern. The aim of this study is to provide a comprehensive non‐surgical treatment for keloid—cocktail therapy. Methods: According to the different changes of keloid with treatment, the treatment was divided into four stages, and different treatment schemes were adopted for each stage. The incidence of side effects of keloid at each stage and the effective rate and cure rate 16 months after the end of treatment were analyzed. Results: All patients completed this study on time, and were followed up 16 months after the end of treatment, the treatment effective rate was 100%, and the cure rate was up to 92.8%. Conclusion: Cocktail therapy can achieve a higher cure rate of keloid, and is worthy of clinical promotion. [ABSTRACT FROM AUTHOR]

Background: The nose is located in the middle of the face; therefore, nasal scarring will bring a significant psychological impact on patients. Although there are many treatment methods for depressed scars, these methods have varying degrees of efficacy and all carry certain adverse effects. A better treatment method is urgent to be found. In this study, the effect of micro‐plasma radiofrequency technology combined with subcision to treat nasal depressed scars is evaluated. Methods: 18 Chinese patients with nasal depressed scars participated in this study. All patients received one session of micro‐plasma radiofrequency treatment first. 2 months later, subcision combined with micro‐plasma radiofrequency technology was performed on them at 6‐month intervals, and a total of 2 sessions of combined treatment were performed. Goodman and Baron Scale was used to evaluate nasal scars before treatment and 6 months after the final session. Results: All 18 patients in this study had Grade 4 nasal scars before treatment. 6 months after the end of treatment, 13 patients (72.2%) showed excellent or near total improvement, and 5 patients (27.8%) showed marked improvement. No adverse side effects were observed during treatment. Patient self‐evaluation indicated that all patients were satisfied with the cosmetic outcomes. Conclusions: In this study, we explored a new treatment method for nasal depressed scars. We used micro‐plasma radiofrequency technology combined with subcision to treat nasal depressed scars and obtained relatively satisfactory results with no adverse effects. [ABSTRACT FROM AUTHOR]

80% of the patients underwent 5 maintenance injections, the keloid in the laser treated area showed a white, soft healing state. Treating cysts in keloids with Ultrapulse mode-fractionated carbon dioxide lasers can effectively cure the cysts, thereby inhibiting the growth of keloids and reducing the recurrence rate of keloids. Treatment of sebaceous cysts in keloids: Ultrapulse mode-fractionated carbon dioxide lasers combined with injection of low-concentration triamcinolone acetonide and 5-fluorouracil.
