Background:
Follow-up studies on auricular reconstruction procedures have reported postoperative complications; some of which can only be reversed with revision surgery. This study aims to provide a feasible surgical strategy based on the Nagata method for patients requiring secondary revision and verify mid-term aesthetic outcomes.
Methods:
Secondary auricular reconstructions based on the Nagata method were performed on seven patients seeking secondary revision between 2017 and 2021. Scores of a five-point Likert scale and artificial intelligence ratings based on convolutional nerve networks were used as outcome measures.
Results:
Five patients underwent complete two-stage ear reconstruction, and the other two patients underwent the first-stage microtia procedure only. Few complications were observed, except in Case 4; this patient required an additional minor surgery after frame exposure 6 weeks after the first-stage procedure. All revised ears showed clear anatomical structures, and all patients were satisfied with the aesthetic results. Statistical analysis showed a significant increase in postoperative versus preoperative scores by convolutional neural network models (p < 0.05). Cases 5 and 6, which involved projection surgeries only, had decreased artificial intelligence appearance scores postoperatively.
Conclusion:
After adequate preoperative evaluation, secondary auricle reconstruction based on the Nagata method can achieve reliable aesthetic outcomes with few complications.
