Objective To investigate the clinical effect of type A botulinum toxin and nipple retractor in correcting severe inverted nipples.Methods All the patients with bilateral severe inverted nipples that sought consulting in the Plastic and Reconstructive Surgery Center of Peking Union Medical College Hospital were included in this study and the patients were randomized into different treatment group with nipple retractor only or BTX-A (Lanzhou,China) combined with nipple retractor.In the combined therapy group,50 u BTX-A was injected into the bottom of each nipple.2 weeks later,nipple retractor was placed and kept wearing for 6 months.For the retractor only group,no BTX-A was used.All the patients were followed up at 1 month,3 months and 6 months after the operation.Nipple projection was measured according to the profile view of pre-and post-operation.Effectiveness and complication rate were compared between the two groups.Results 20 patients were included in this study.Average nipple projection in the combined therapy group was (1.12±0.13) cm,(0.95± 0.10) cm and (0.73±0.11) cm (3 months,6 months and 12 months post-operation,respectively),which had a significant difference from that of the retractor group [(0.81±0.10) cm,(0.72±0.12) cm and (0.53±0.10) cm].Total complication rate of combined group was also lower than that of retractor group.The complications of the combined therapy group included hypopigmentation (1 case),without skin ulcer or wire dislocation.However in the retractor group,complications included skin ulcer (2 cases),hypopigmentation (1 case) and dislocation (1 case).No severe complications such as nipple necrosis happened in both groups.Conclusions BTX-A combined with nipple retractor is an effective method in correcting severe inverted nipple with low complication rate.

Objective To explore a new method for improving healing of skin graft donor sites.Methods A total of 40 patients who needed intermediate thickness skin graft from thigh,from January 2014 to December 2015,were randomly devided into experiment group and control group.Skin graft donor sites of the experiment group were covered with Physiotulle Ag and Allevyn foam dressing,while donor sites of the control group were covered with petrolatum impregnated gauze,sterile gauze,and compression bandage.Postoperative infection rate,pain scoring during the first dressing change,time of dressing change between operation and complete healing,duration for complete healing,and the area of non-healing two weeks after operation were compared and statistical analysis was performed with SPSS17.0.Results There was no infection in the experiment group.Two patients developed infection in the control group,with wound exudate culture positive for pseudomonas aeruginosa,and the wounds healed after dressing change.The experiment group was significantly better than that of the control group in pain scoring during the first dressing change,time of dressing change between operation and complete healing,duration of complete healing (U=81.5,P=0.001;U=109.5,P=0.011;t=0.769,P＜0.001).Conclusions The Physiotulle Ag combined with Allevyn foam dressing can enhance healing of skin graft donor sites,alleviate pain of the patient,and reduce dressing change.This method is easy to perform,and skin graft donor sites heal well in two weeks,which may lead a prospected application.

Objective: The purpose of this study is to systematically review the literature about surgical management of lymphedema, to provide recomendations for the surgical treatment plan of the disease. Methods: Cochrane Library and EMBASE databases were searched from January 1st, 2007 to October 1st, 2017 for the literature related to the surgical treatment of lymphedema. Data were extracted from clinical studies matching our inclusion criteria. Meta-analysis was performed with R 3.4.2. Results: 71 studies were included, out of which 4 studies described were excision, 9 were liposuction, 33 were lymphvenous anastomosis(LVA), 23 were vascularized lymph node transfer(VLNT) and 5 were combined therapy. The excess volume reduction were averaged 96.86%(95%CI: 87.38%—106.33%, I²=0%)for liposuction, 34.64%(95%CI: 19.80%—49.47%, I²=72%)for LVA, 36.85%(95%CI: 12.40%—61.30%, I²=81%) for VLNT. Conclusions With further understanding of the pathophysiology of lymphedema and development of radiologic and surgical technique, surgical treatment has the potential to play an important role in lymphedema complex management.

Objective: To introduce the experience in skin defect reconstruction with keystone design perforator flap. Methods: From January 2012 to December 2012, 26 patients with different types of skin defect were repaired with keystone design perforator flaps, including 21 classic keystone design perforator flaps, 3 short incision keystone design perforator flaps, and 2 Omega variant keystone design perforator flaps. Results: One patient suffered partial flap loss and healed secondarily. All other patients recovered smoothly without complications. Conclusions Keystone design perforator flap offers a versatile technique for skin defect reconstruction except for scalp.

Objective:To observe the effect of a new modified double-eyelid operation.Methods:From February 2018 to January 2021, modified tarsal plate-orbicularis oculi muscle-orbital septum (TMS) suture was performed in 193 double-eyelid operation in the plastic surgery department of Peking Union Medical College Hospital, including 14 males and 179 females. The patients aged from 18 to 45 years with an average of (22.3±4.2) years. The patients were followed up for 6-24 months to observe the morphology of the double eyelid fold and complications.Results:The 193 patients were included. The double eyelid lines of 173 patients were smooth, natural, durable and the scar was shallow; both doctors and patients were satisfied. There were no obvious complications after the operation. The double eyelid line became shallow or disappeared in 11 patients, and the double eyelid asymmetry occurred in 7 patients after the operation. However, the folds were symmetrical and natural after secondary operation, and both doctors and patients were satisfied.Conclusions:TMS suture not only establishes a firm adhesion, but also effectively transmits the force of the levator aponeurosis with significant advantages. After the operation, the double eyelid line is smooth, natural and stable. Both doctors and patients are highly satisfied. It is an improved double eyelid procedure worthy of clinical promotion.
