Application of autogenous nasal septal cartilage in the plasty of nasal tip and columella

Objective To evaluate the effect of anlogenous septal cartilage in repair of nasal tip and columella. Methods Nasal septal cartilage was transplanted between medial angles of greater alar cartilage at the nasal columella as a support,and a scutellate cartilage was transplanted to the nasal tip. Results All 108 cases were followed up for 1 ～ 2 years,they were satisfied with

Effect of Expanded Polytetrafluoroethylene Combined with Autologous Ear Cartilage in Nasal Plastic Surgery

Objective:To explore the effect of combined application of expanded polytetrafluoroethylene and autologous ear cartilage in nasal plastic surgery.Methods:76 cases of nasal plastic surgery patients in our hospital from September 2019 to September 2020 were selected as the research objects and divided into experimental group(38 cases,treated with expanded polytetrafluoroethylene+autologous ear cartilage surgery)and control group(38 cases,treated with autologous ear cartilage surgery).The treatment effect,appearance score and complications were compared.Results:The total effective rate of the experimental group(97.37%,37/38)was higher than that of the control group(78.95%,30/38),P<0.05;After treatment,the appearance score of the experimental group was(8.97±0.37),which was significantly higher than that of the control group(P<0.05);The total incidence of complications in the experimental group(5.26%,2/38)was significantly lower than that in the control group(21.05%,8/38),P<0.05.Conclusion:In the process of nasal plastic surgery,the combined application of autologous ear cartilage surgery and expanded polytetrafluoroethylene has obvious effect,improves the appearance of patients,and has less postoperative complications,which is worthy of promotion.

Treatment of microtia:past,present and future

The purpose of this review article is to review the reconstructive method available for the treatment of microtia and highlight the recent advances.The well established technique developed by Brent and Nagata are still must widely performed procedure for microtia reconstruction.Various modification of this technique has been reported in the literature.Synthetic framework is seen as an alternative to autogenous costal cartilage framework because of ease of the procedure.More recently,tissue engineering is seen as the most promising treatment.This article gives an overview of the current practice in the field of microtia reconstruction and summarizes the recent surgical developments and relevant tissue engineering research.

Full retroauricular skin and fascia expansion in microtia reconstruction:a single center experience of 166 cases

Aim:Ear reconstruction is a challenge for plastic and reconstructive surgeons.The ear requires sufficient skin coverage and a three-dimensional(3D)cartilage framework.In this paper,the authors present their 10-year experience in microtia reconstruction using tissue expansion and an autogenous rib cartilage framework.Methods:Ear reconstruction was performed in 3 operative stages.During the first procedure,a 50-80 mL kidney or cylinder-shaped expander was implanted deep to the subcutaneous fascia of the retroauricular mastoid region.Over a period of 3-5 months,the expander was filled to a final volume of 80-110 mL.In the next operation,the retroauricular fascia was eliminated or reserved following expander removal,and the autogenous costal cartilage framework was placed below the expanded skin flap.At the third and final stage,the earlobe transposition,tragus construction and conchal deepening were performed.Results:A total of 165 patients(166 ears)were reconstructed using tissue expansion and an autogenous rib cartilage framework.Complications included hematomas in 3 cases,expander exposure in 8 cases,cartilage exposure in 6 cases,infection and cartilage resorption in 2 cases,exposure of steel wire in 4 cases,and aseptic seroma in 2 cases.Follow-up ranging from 3 months to 5 years showed that 159 patients were satisfied with the reconstructed ear including size,location,projection,convolution,skin-colour matching,symmetry with opposite ear.Conclusion:Expansion of the retroauricular skin and fascia can provide sufficient non-hair-bearing skin and tissue for coverage of a three-dimensional costal cartilage framework.Avoidance and prompt treatment of complications are advised in order to obtain a satisfactory reconstruction of the ear.
