"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."
A total of 19 patients were involved in this single-center, retrospective cohort study. All patients underwent the described surgical technique. Data were collected preoperatively, immediately after the surgery, and at the last follow-up, including auricular length, width, perimeter, and conchal bowl depth. Patient satisfaction was assessed using the Visual Analog Scale (VAS).
The 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 ± 1.78 mm to 17.32 ± 1.28 mm 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.
The 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.
“扁平耳”是二级贝壳型小耳畸形的一个亚型，其特征是贝壳状碗严重发育不良。传统的手术技术通常依赖于自体肋软骨，这会带来一些风险和并发症。本研究旨在介绍一种新的手术技术，该技术使用自体耳软骨进行耳廓畸形矫正手术，并同时重建贝壳状碗，用于治疗“扁平耳”。
这项单中心回顾性队列研究共纳入 19 名患者。所有患者均接受了所述手术技术。在术前、术后即刻和最后一次随访时收集了包括耳廓长度、宽度、周长和贝壳状碗深度在内的数据。采用视觉模拟评分（VAS）评估患者满意度。
研究包括 12 名男性和 7 名女性，平均年龄为 10.67 ± 3.86 岁。术后结果显示耳廓测量值有显著改善，患耳与健耳几乎对称。贝壳状碗深度从术前的 4.33 ± 1.78 毫米恢复到术后的 17.32 ± 1.28 毫米。患者满意度的 VAS 评分从术前的 1.44 ± 0.92 显著增加到术后的 7.72 ± 1.49，最后一次随访时保持稳定。
与传统的基于肋软骨的耳廓畸形矫正手术相比，该新技术提供了一种有前途的替代方法，可获得出色的美学效果和高患者满意度。这种方法可能为“扁平耳”和相关耳廓畸形患者提供更多的治疗选择，具有微创性和未来听觉康复的潜力。
