Methods:
From January 2015 to January 2021, auricular reconstruction was performed in 38 adult patients (39 ears) of congenital microtia based on autologous costal cartilage. The whole procedure was divided into 2 stages: stage I, the individualized framework carved with autologous costal cartilage was inserted into subcutaneous pocket in the mastoid region; then, the earlobe was transposed backward; and stage II, ear elevation, harvesting the retroauricular fascial flap to cover the support scaffold and closing the defect with free skin graft, was performed.
Results:
All patients successfully underwent ear reconstruction. The follow-up time ranged from 3 months to 3 years. Infection occurred in 1 patient. The ear frameworks were partially broken at the helix in 4 cases. Retroauricular graft skin survival was poor in 1 patient. Retroauricular hypertrophic scars occurred in 2 cases. Bad projection of the reconstructed ear occurred in 1 case. Totally 38 patients were satisfied with the results.
Conclusions:
According to the physiological characteristics of the costal cartilage and skin soft tissues of adult patients, improvements are made to details based on the Nagata's method, so that the adult patients with microtia can obtain satisfactory surgical results.
