Abstract
Backgrounds"Flat ear" is a subtype of Grade II conchal-type microtia characterized by severely underdeveloped conchal bowl. Traditional surgical techniques often rely on autologous costal cartilage, which poses several risks and complications. This study aimed to introduce a novel surgical technique using autologous ear cartilage in auricular deformity correction surgery with simultaneous conchal bowl reconstruction for “flat ear”. MethodsA total of 19 patients were involved in this single-center, retrospective cohort study. All patients underwent the described surgical technique. The data before the surgery, immediately after the surgery, and at the last follow-up were collected, including length, width, perimeter of auricle and depth of conchal bowl. Patient satisfaction was assessed via the Visual Analog Scale (VAS). ResultsThe study included 12 males and 7 females, with an average age of 10.67 ± 3.86 years. Postoperative results showed significant improvements in auricular measurements, with the affected ear achieving near symmetry with the normal ear. The mean conchal bowl depth was restored from a preoperative 4.33±1.78mm to 17.32±1.28mm postoperatively. VAS scores for patient satisfaction increased significantly from 1.44±0.92 preoperatively to 7.72±1.49 postoperatively, with stability observed at the last follow-up. ConclusionThe novel technique offers a promising alternative to traditional costal cartilage-based auricular deformity correction surgery, providing excellent aesthetic outcomes and high patient satisfaction. This approach may expand treatment options for patients with "flat ear" and related auricular deformities, with reduced invasiveness and potential for future auditory rehabilitation.
