BACKGROUND: Microtia with constricted ear features represents a challenging congenital deformity characterized by the variable shape and large volume of the remnant cartilage and skin involved. This study aimed to evaluate the efficacy and safety of a method using helix costal cartilage scaffold and postauricular flap advancement for the correction.
METHODS: This prospective study analyzed the clinical and postoperative data of 121 patients diagnosed with microtia and constricted ear features, treated at the authors' institution between January of 2020 and January of 2023. All patients underwent helix reconstruction using the eighth or ninth costal cartilage combined with postauricular flap advancement. Outcomes were assessed based on the incidence of postoperative complications and auricular aesthetic scores. The aesthetic evaluation of the reshaped auricle was based on a 4-point Likert scale (ie, 1 = poor, 2 = fair, 3 = good, and 4 = excellent).
RESULTS: The postoperative follow-up period ranged from 12 months to 3 years (mean, 18.5 months). All patients achieved successful helix expansion, with reconstructed ears showing improved symmetry and shape comparable to the contralateral normal ears. The average aesthetic score was 3.4 of 4. Complications included suture exposure in 8.3% of cases and cartilage protrusion in 4.1%, both managed without significant issues. There were no instances of skin necrosis, costal cartilage exposure, or infection.
CONCLUSION: The combination of helix costal cartilage scaffold and postauricular advancing flap offers a reliable and effective method for correcting microtia with constricted ear features, providing satisfactory aesthetic outcomes with minimal complications.
CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
