    Abstract:
    BACKGROUND: The verisimilitude of the reconstructed auricle and its long-term stability largely depends on the framework sculpting. This study described three kinds of minor modifications based on Firmin's way of sculpting the auricle framework and reported the clinical outcomes achieved with them. METHODS: We conducted a retrospective study of congenital microtia patients undergoing detail-improved auricular reconstruction from June 2016 to June 2020. The three kinds of minor modifications included: (1) fabricating the base frame using the 7th costal cartilage, (2) fabricating the helix and the antihelix complex using the 8th costal cartilage, and (3) fabricating the helix using the combination of the 8th and 9th costal cartilage. RESULTS: Ninety-eight patients (aged 9-27 years, 62.2% male) were included. Ninety-five patients (97.0%) adopted minor modifications 1, 2, and 3 patients (3.0%) adopted minor modifications 1, 2, and 3. All patients achieved an excellent auricle appearance and a well-laid foundation for subsequent operations. During the follow-up period, 89 patients (90.8%) were satisfied with the reconstructed auricles, 6 (6.1%) complained of hypertrophic scars in the retroauricular sulcus or pigmentation in the skin graft area, and 3 (3.1%) developed surgery-related complications. CONCLUSIONS: Three minor modifications of the auricle framework sculpting can make more satisfactory use of cartilage and adjust with the flexibility of the reconstructed auricle in different situations, making it similar to the contralateral auricle, thus, improving patients' satisfaction.
