Auris Nasus Larynx. 2019 Aug;46(4):576-582. doi: 10.1016/j.anl.2018.10.017. Epub 2018 Nov 20.
An auricular pseudocyst is a fluid filled cavity, characterized by a lack of epithelium, in the intra-cartilaginous space. Clinically, it presents as a painless lump on the upper anterior surface of the ear. Various treatment methods have been discussed in the literature, including aspiration, incision and drainage, or steroid injection. However, these approaches are associated with a high rate of recurrence and results are often esthetically unsatisfactory; therefore, a need for improved treatment approaches remains.
From March, 2015, to June, 2017, 15 patients with auricular pseudocyst were treated with surgical deroofing followed by local contour pressure dressing with a simple bolster. In addition, the structure of the auricular pseudocyst was assessed at a microscopic level.
Patients were followed up for a mean period of 12 months, during which time there were no reports of postoperative complications or recurrence. The results were cosmetically excellent in all patients and no cartilage deformity was seen. Considering the composition of pseudocysts seen on microscopic evaluation, deroofing to remove the anterior leaflet and removal of debris from the posterior leaflet is an appropriate treatment modality.
This reliable and simple approach may be recommended as first line treatment for auricular pseudocysts to avoid recurrence and complications associated with other treatment modalities, such as cartilage deformity, skin depigmentation, and scarring.
耳廓假性囊肿是软骨内间隙的一个充满液体的腔隙，其特征为缺乏上皮组织。临床上，它表现为耳上前表面的无痛性肿块。文献中已讨论了多种治疗方法，包括抽吸、切开引流或类固醇注射。然而，这些方法的复发率很高，且结果在美学上往往不尽人意；因此，仍需要改进治疗方法。
2015年3月至2017年6月，对15例耳廓假性囊肿患者采用手术掀顶术，随后用简单的支撑物进行局部轮廓加压包扎。此外，在显微镜水平评估耳廓假性囊肿的结构。
患者平均随访12个月，在此期间无术后并发症或复发报告。所有患者的结果在美学上均极佳，未见软骨畸形。考虑到显微镜评估中所见假性囊肿的组成，掀顶以去除前叶并清除后叶的碎屑是一种合适的治疗方式。
这种可靠且简单的方法可作为耳廓假性囊肿的一线治疗方法推荐，以避免与其他治疗方式相关的复发和并发症，如软骨畸形、皮肤色素脱失和瘢痕形成。
