Three-Dimensional Tension Reconstruction of Periauricular Muscles Combined With Transfer of Retroauricular Fascia Flap For the Repair of Congenital Cryptotia.

BACKGROUND

Congenital cryptotia, a common ear deformity in Asia, significantly affects both the shape and function of the auricle. Various surgical methods currently exist for cryptotia correction. This article presents a technique involving the reconstruction of 3-dimensional muscle tension of the auricle combined with the transfer of the retroauricular fascia flap, yielding stable and satisfactory outcomes.

MATERIALS AND METHOD

This study included 32 patients with congenital cryptotia who underwent surgery between January 2023 and June 2024. The correction was achieved through a combination of 3-dimensional muscle tension reconstruction around the ear and retroauricular fascia flap transfer. Postoperatively, the morphology and symmetry of the patients' auricles were evaluated, and follow-up assessments were conducted to gauge satisfaction and monitor complications.

RESULTS

Postoperative evaluations indicated that all patients' deformities were effectively corrected, with a significant improvement in aesthetic scores compared with preoperative levels. The average follow-up period was 11±3.96 months. Of the patients, 30 (93.75%) were highly satisfied, 2 (6.25%) were satisfied, and none were dissatisfied. One patient (3.33%) experienced wound infection and delayed healing in the early postoperative period, which improved after dressing changes.

CONCLUSIONS

The surgical method of reconstructing 3-dimensional muscle tension of the ear combined with the transfer of the retroauricular fascia flap has proven to be a reliable option for the treatment of cryptotia. This method is straightforward to perform, achieves satisfactory repair outcomes, and has a low incidence of complications and recurrence.
