DEVELOPMENT IN THEFIELD OF PLASTIC SURGERY

Objective To summarize the recent development in the plastic and reconstructive surgery. Methods The related literaturewas reviewed and the main achievements in the field of plastic surgery were summarized. Results Plastic and reconstructive surgery was one ofthe quickly-developed fields in the world medicine, especially aesthetic plastic surgery. Reconstructive plastic surgery and aesthetic plastic surgery would be bined in the future. The “aesthetic hand surgery” was a very important branch of the hand surgery,so not only the function recovery of the hand deformities but also the aesthetic sculpture for the deformed hand should be emphasized. Evaluation on measurement of the facial paralysis reconstruction was a main part of the facial examination. The allotransplantation of the face became more developed. The anatomical research on the cutaneous perforator arteries, vascularisation of the biceps femorismuscle, and the gracilis perforator flap was well performedby the plastic surgeons.

Survival assessment regarding vascularized osseous flaps on reconstruction for mandibular defect: a Bayesian network meta-analysis

ObjectiveTo systematically review the survival rate of different vascularized bone flaps in mandibular defect repair and reconstruction by Bayesian network meta-analysis. MethodsThe PubMed, EBSCO, Scopus, Web of Science, Cochrane Library, WanFang Data and CNKI databases were electronically searched to collect clinical studies related to the objectives from inception to February 2024. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. The Bayesian network meta-analysis was carried out applying R software. ResultsA total of 24 studies involving 1 615 patients were included. The results of meta-analysis showed that the respective survival rates of fibula free flap (FFF), deep circumferential iliac artery flap (DCIA), scapula flap, and osteocutaneous radial forearm flap (ORFF) were 95.62%, 94.09%, 98.16%, and 93.75%. Moreover, the network meta-analysis failed to show a statistically significant difference between all comparators. Conclusion?Current evidence shows that different vascularized bone flaps have similar survival rates in mandibular defect repair and reconstruction. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.

SEVERAL ADVANCES IN PLASTIC SURGICAL TECHNIQUES IN THE TREATMENT OF POSTBUEN DEFORMITY

Abstract Postburn deformities, including hypertrophic scars, scar contracture and defect or deformity of tissue or organ, are the commonest disorders in plastic surgery. It is also difficult to deal with. If the diformity involved multiple organs, oftentimes the teatmentis very difficult because the material for repair is limited and the donorsite usually could not provide adequate amount of skin for repair. Since 1978,2496 cases of various postburn deformities were admitted. In this article, theoptimal time to operate was discussed. The use of flap transfer and soft tissueexpander was described. Prolonged traction in the treatment of severe contracture of large joint was also described.

顱耳溝小切口微創手術治療先天性隱耳畸形

目的 總結顱耳溝小切口微創手術治療先天性隱耳畸形的療效。 方法 2011 年 1 月—2015 年 5 月收治先天性隱耳畸形 8 例，其中男 6 例，女 2 例；年齡 5～13 歲，平均 10 歲。單側 3 例，雙側 5 例。13 只隱耳均可用外力牽拉復位至正常大小形態及顱耳溝。于顱耳溝內設計長約 3 cm 弧形切口，并充分松解耳廓軟骨與顱側面、耳廓上部軟骨間及軟骨和皮膚之間的纖維粘連，游離顱側面皮膚向顱耳溝推進修復創面缺損，術后紗布卷固定支撐耳廓 3 周。 結果 術后 8 例患者 13 只隱耳畸形均矯正滿意；術后 3 周拆除支撐紗布卷后耳廓無回縮，形態正常。8 例患兒均獲隨訪，隨訪時間 1～3 年，平均 1 年 6 個月。耳廓外形無明顯回縮。1 例術后 1 周耳后皮膚部分壞死，為紗布卷偏大致皮膚長期受壓缺血所致，去除紗布卷后換藥愈合。 結論 顱耳溝小切口微創手術是治療先天性隱耳畸形有效而簡便的手術方法。
