Objective To investigate the application effect and manufacturing skills of autologous costal cartilage scaffold in ear reconstruction for *** From January 2016 to January 2019,41 patients with microtia reconstruction in our hospital were selected,all of whom were type II or type III pediatric *** patients underwent auricle reconstruction and retroauricular skin expansion and autologous costal cartilage *** first stage of the operation is to insert a skin dilator behind the residual ear and inject water to *** second stage of the operation is to carve and repair the soft ribs(usually 6 or 7 ribs)from the body,make a three-dimensional auricle support for auricle reconstruction,place a negative pressure drainage tube,and follow up for 3 to 6 months to observe the three-dimensional shape of the reconstructed auricle and the formation of cranioauricular *** 41 patients with microtia had good three-dimensional shape of auricle reconstruction,normal auricle position,moderate cranioauricular angle,good helix and triangular fossa structure,and good bilateral *** and their families were satisfied with the effect of auricle *** Autologous costal cartilage is a good scaffold for auricle *** is through efficient and elaborate carving and splicing that a good three-dimensional auricle structure can be *** with early flap expansion,a good postoperative appearance effect can be obtained,which is the appropriate method for auricle reconstruction at present.

Aim:ear reconstruction is a challenge for plastic and reconstructive *** ear requires sufficient skin coverage and a three-dimensional(3D)cartilage *** this paper,the authors present their 10-year experience in microtia reconstruction using tissue expansion and an autogenous rib cartilage ***:ear reconstruction was performed in 3 operative *** the first procedure,a 50-80 mL kidney or cylinder-shaped expander was implanted deep to the subcutaneous fascia of the retroauricular mastoid *** a period of 3-5 months,the expander was filled to a final volume of 80-110 *** 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 *** the third and final stage,the earlobe transposition,tragus construction and conchal deepening were ***:A total of 165 patients(166 ears)were reconstructed using tissue expansion and an autogenous rib cartilage *** 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 ***-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 ***:Expansion of the retroauricular skin and fascia can provide sufficient non-hair-bearing skin and tissue for coverage of a three-dimensional costal cartilage *** and prompt treatment of complications are advised in order to obtain a satisfactory reconstruction of the ear.
