Abstract:Objective To explore the clinical effect and experience of modified Brent method for total ear reconstruction in the treatment of congenital microtia. Methods A total of 20 children with congenital microtia treated by modified Brent method total ear reconstruction in our hospital from November 2018 to April 2021 were selected. 8.7 years old. In the first stage, the residual ear is first treated, the mastoid region behind the ear is separated to form a cyst, and the earlobe is transposed at the same time. Take the costal cartilage on the opposite side of the affected ear and carve it into the auricle bracket. On the basis of traditional carving, the tragus is carved at the same time to deepen the depth of the auricular navicular and triangular fossa as much as possible. Possibly elevated and the tip left longer to accentuate the depth of the helix. The auricle stent is embedded in the back of the ear cavity. The second phase, "Earling", the formation of the cranial ear angle. Stage 3: Concha cavity formation. Results: Among the 20 cases of ear reconstruction, 1 case had hematoma in the first-stage operation, 1 case had infection in the second-stage operation, and 1 case had stent exposure. All recovered after local treatment, and the next operation was continued. 20 patients were followed up for 3-9 months after the three-stage operation. The reconstructed ears showed good symmetry of both ears, good shape of the helix crus and tragus, deepened cranio-auricular grooves, and smooth transition between the earlobe and the lower part of the auricle. Satisfied with the overall appearance of the ear.conclusion The modified Brent method of total ear reconstruction can better highlight the fine structures of the tragus, helix crus, triangular fossa and earlobe, and can better present the three-dimensional sense of reconstructed ear. This method can provide reference for the selection of surgical methods for congenital microtia.
