The lop ear deformity is defined by a deficient helix and scapha, underdeveloped anthelix, and downfolding of the helix. The terminology used is still confusing, and the treatment is not entirely structured. The aim of this study was to provide a new systematic surgical approach of this deformity based on our center's experience.
All patients undergoing surgical correction of lop ears between 2007 and 2019 at Great Ormond Street Hospital were included. Patients' data, surgical techniques, and postoperative complications were recorded.
Based on our records, we identified 3 surgical techniques for the correction of lop ears, based on the degree of deformity encountered. In a mild lop ear, correction was achieved with a modified otoplasty technique by improving the definition of the antihelix and superior crus. In a moderate deformity, additional remodeling of the lidded helix was performed (extended otoplasty), whereas for the severe lop ear, the amount of cupping and the deficient cartilage required formal reconstruction using a carved rib cartilage framework. There were a total of 109 patients and 146 lop ears: 58 mild, 27 moderate, and 61 severe lop ears.
We feel that there is a point in the spectrum of congenital ear deformity when a severe lop ear becomes a conchal microtia and recommend this approach to simplify the management of these cases. This is intended to bring greater clarity to how to deal with lop ears, based on the severity of the deformity and the surgical techniques used.
招风耳畸形的定义为耳轮和耳甲腔发育不良，对耳轮不明显，耳轮向下折叠。目前使用的术语仍然存在混淆，治疗方法也不完全规范。本研究旨在根据我们中心的经验，提供一种治疗该畸形的新的系统手术方法。
在 2007 年至 2019 年间，所有在大奥蒙德街儿童医院接受手术矫正招风耳的患者均被纳入研究。记录患者数据、手术技术和术后并发症。
根据我们的记录，我们根据所遇到的畸形程度，确定了 3 种矫正招风耳的手术技术。在轻度招风耳中，通过改善对耳轮和上脚的定义，采用改良的耳成形术进行矫正。在中度畸形中，进行额外的盖状耳轮塑形（扩展耳成形术），而对于严重的招风耳，需要使用雕刻肋软骨框架进行正式的杯状和软骨缺损重建。共有 109 名患者和 146 只招风耳：58 例轻度，27 例中度，61 例重度。
我们认为，在先天性耳部畸形的范围内，当严重的招风耳变成耳廓微小畸形时，就需要采用这种方法来简化这些病例的管理。这旨在根据畸形的严重程度和所使用的手术技术，更清晰地处理招风耳。
