Cryptotia is a congenital auricular deformity characterized by the partial embedding of the upper auricle beneath the temporal scalp skin, leading to aesthetic and functional issues. This study introduced a novel surgical technique for severe cryptotia.
From January 1, 2019 to January 1, 2023, patients with unilateral severe cryptotia treated at our center were included in this study. The surgical technique involved a retroauricular Z-shaped skin flap for sufficient skin coverage and auricular cartilage stretching for contour improvement. Auricular indicators including perimeter, width and length, and vertical distance from the highest point of the helix to the skull (defined as "D") were measured pre- and postoperatively. Patient satisfaction was assessed using the Visual Analog Scale (VAS). Data were analyzed with IBM SPSS Statistics.
A total of 41 patients were included. Postoperatively, significant improvements were observed in auricular dimensions, with the affected ear achieving comparable perimeter, width, and length to the normal ear (98.40±9.82 mm vs. 100.92±10.15 mm, P=0.08; 29.54±2.51 mm vs. 29.76±3.02 mm, P=0.74; 53.53±4.80 mm vs. 54.56±5.08 mm, P=0.17). The D value of the affected ear also improved significantly (4.24±1.99 mm vs. 11.99±2.77 mm, P<0.05) immediately after the surgery, showing no significant difference when compared with the normal ear (11.99±2.77 mm vs. 12.35±3.60 mm, P=0.61). Patient satisfaction improved significantly (VAS: 1.49±0.90 to 7.93 ± 1.23, P<0.05).
This technique effectively addressed the challenges of traditional cryptotia correction methods by reducing donor site morbidity and providing inconspicuous scarring.
隐耳是一种先天性耳廓畸形，其特征是耳廓上部部分埋于颞部头皮皮下，导致美观和功能问题。本研究介绍了一种治疗重度隐耳的新型手术技术。
2019年1月1日至2023年1月1日期间，在本中心接受治疗的单侧重度隐耳患者被纳入本研究。手术技术包括采用耳后Z形皮瓣以获得足够的皮肤覆盖，并进行耳廓软骨拉伸以改善轮廓。术前和术后测量耳廓指标，包括周长、宽度和长度，以及耳轮最高点到颅骨的垂直距离（定义为“D”）。使用视觉模拟量表（VAS）评估患者满意度。数据采用IBM SPSS Statistics软件进行分析。
共纳入41例患者。术后，耳廓尺寸有显著改善，患耳的周长、宽度和长度与正常耳相当（98.40±9.82mm对100.92±10.15mm，P=0.08；29.54±2.51mm对29.76±3.02mm，P=0.74；53.53±4.80mm对54.56±5.08mm，P=0.17）。患耳的D值在术后即刻也有显著改善（4.24±1.99mm对11.99±2.77mm，P<0.05），与正常耳相比无显著差异（11.99±2.77mm对12.35±3.60mm，P=0.61）。患者满意度显著提高（VAS：1.49±0.90至7.93±1.23，P< 0.05）。
该技术通过减少供区并发症并提供不明显的瘢痕，有效解决了传统隐耳矫正方法的挑战。
