Background:
This study was performed to explore the clinical application of the Nagata's technique for combing tissue expansion in auricular reconstruction.
Methods:
The auricular reconstruction was performed in two surgical stages. At the first stage, an 80 ml expander was inserted in the mastoid region after preoperative evaluation. After a gradual expansion period and nearly 2-month rest time, the flap achieved the appropriate area and thickness. At the second stage, the expander was removed and a three-layer cartilage framework was inserted into the pocket through a Y-shaped lobule incision, and the earlobe and tragus were rebuild simultaneously.
Results:
From 2012 to 2016, 104 microtia patients underwent auricular reconstruction with this method in our hospital. Patients were followed up for between 6 months and 2 years. Ninety-six patients and their families were satisfied with the results, especially the clear outline, appropriate color, good projection, and the symmetry of bilateral ears. Complications of ischemic necrosis of the distal earlobe and skin of the concha cavity occurred in two cases, hematoma after the first stage occurred in two cases, and four patients needed further restorations.
Conclusions:
A novel two-stage strategy combing tissue expansion and Nagata's technique is an effective and efficient technique for auricular reconstruction with satisfying medium-term results.
