Objective Blepharoplasty is a typical complex structural system, which involves many factors and the interaction among them. Therefore, it is the basis of controlling the occurrence of medical complications in blepharoplasty to clarify the hierarchical relationship of various risk factors and find out the key risk factors. Methods On the basis of identifying the risk factors for quality management of blepharoplasty by means of literature research, questionnaire survey and expert interview, the risk factor model of blepharoplasty quality management were analyzed and constructed. The relationship between the risk factors and the degree of influence on the risk factors was studied using Decision‐Making Trialand Evaluation Laboratory and Interpretative Structural Modeling Method, and the hierarchical structure model of the risk factors for blepharoplasty quality management was obtained. Results Six levels of risk factors in quality management of blepharoplasty were identified and classified, and the causal attributes among risk factors were determined. Six key risk factors in quality management of double eyelid surgery were determined according to centrality, and finally the above risk factors were divided into three categories: direct cause, excessive cause, and essential cause. Conclusions This study realizes the comprehensive risk factor analysis of the complex system of quality management of blepharoplasty, which can provide reference for plastic surgeons to make safety decisions of blepharoplasty.

Background Douyin APP is the short video APP with the largest number of users in China. Objective This study aimed to evaluate the quality and reliability of short videos about cosmetic surgery on Douyin. Methods In August 2022, we retrieved and screened 300 short videos related to cosmetic surgery from Douyin, extracted basic video information, encoded the content and identified the video source. The quality and reliability of short video information were evaluated using the DISCERN instrument. Results A total of 168 short videos of cosmetic surgery were included in the survey, and the video sources included personal accounts and institutional accounts. Overall, the total proportion of institutional accounts (47/168, 27.98%) is significantly less than that of personal accounts (121/168, 72.02%); nonhealth professionals received the most praises, comments and even collections and reposts, while for‐profit academic organizations or institutions received the least. The DISCERN scores of 168 short videos of cosmetic surgery were 3.74–4.58 (average 4.22). Content reliability ( p = .04) and overall short video quality ( p = .02) are significantly different, but short videos published from different sources have no significant difference in treatment selection ( p = .052). Conclusion The overall information quality and reliability of short videos about cosmetic surgery on Douyin are satisfactory in China. Patient or Public Contribution The participants were involved in developing research questions, study design, management and conduct, interpretation of evidence and dissemination.

Background: The glandular fluid secreted by apocrine sweat glands is decomposed by parasitic bacteria on the skin surface and releases a bad smell called axillary osmidrosis.Objective: To evaluate the effect of power-assisted rotary cutter with negative pressure suction through small incision for axillary osmidrosis.Methods: From January 2017 to January 2022, 647 patients with axillary osmidrosis underwent power-assisted rotary cutter with negative pressure suction through small incision surgery to treat for axillary osmidrosis. The operation time (min), intraoperative bleeding (ml) and recovery time (days) were counted. Three months after operation, the amount of underarm sweat, the disappearance of underarm hair, the incidence of operation, the effective rate of operation, and the satisfaction of operation results were evaluated by questionnaire.Results: There were no postoperative complications except five cases of mild axillary pigmentation after 3 months. All patients evaluated good odor elimination. No patient was rated as average or poor. No recurrence. Conclusion:Power-assisted rotary cutter with negative pressure suction through small incision is an effective and ideal surgical method to reduce the complications and recurrence of axillary osmidrosis.

Aim To explore the effect of absorbable collagen thread and cosmetic suture technique on scar inhibition after emergency facial trauma in children, and to explore the application value of absorbable collagen thread in emergency facial trauma. Methods Children who received emergency treatment of facial trauma in plastic surgery department from January 2021 to January 2022 were analysed retrospectively, and were divided into absorbable collagen thread group and non‐absorbable nylon thread group. The general data, scar appearance and local symptoms of the two groups were analysed, and the scar appearance was scored by scar beauty rating scale and non‐inferiority test was analysed statistically. Results A total of 632 children with facial trauma were included in this study, including 458 patients with absorbable collagen thread and 174 patients with non‐absorbable nylon thread. The SCAR score of the absorbable collagen thread group (3.03 ± 1.57) was similar to that of the non‐absorbable nylon thread group (2.98 ± 2.39) (95% confidence interval), and the final scar outcome score was not statistically different (P > 0.05). All families of the patients were satisfied with the results of the procedure, 95% very satisfied. Conclusion The use of absorbable collagen thread and cosmetic suture technique to treat the wounds of children with facial emergency trauma, resulted in good wound healing, little scar expansion, low incidence of erythema and pigment abnormality, no obvious surgical trace, and no scar hypertrophy or atrophy. The overall impression was good, the pain of stitch removal was avoided for children's patients, and the satisfaction of family members was high. Cosmetic suture technique with absorbable sutures is worthy of clinical application.
