Auricular pseudocyst (AP) is a benign, noninflammatory swelling to the ear, located on either the front or side surface. Deroofing surgery with variable compression methods is considered the most effective method. However, post-operative wound pain is the main drawback following compression. We are introducing a novel painless surgical procedure which involves deroofing technique followed by Merocel® compression dressing.
From 2015 to 2020, thirty-one patients with AP received this new surgical compression method in our university-affiliated tertiary hospital. Retrospective chart review and the analysis of the results were conducted.
All patients had unilateral lesions, with left side lesions (58.1%) predominant. The concha cymba (38.7%) and concha cavum (35.8%) were the most common sites. Previous aspiration or drainage had been performed for the cysts in eight patients (25.8%). Only one patient had the recurrence after post-operative 3 months and received the revised surgery without following recurrence and discomfort. Among all patients, 29 (93.5%) patients claimed minimal pain around 0 or 1 in numeric rating scale of pain score. Three patients had mild ecchymosis but recovered after conservative treatment. One patient had mild auricular deformity after surgery due to pre-treatment partial cartilage necrosis. All patients had follow-up for at least 6 months.
This novel Merocel® compression dressing technique to treat AP after deroofing is an effective procedure. Minimal pain, simple to do and easily acquired materials were the advantages of this novel procedure.
耳甲假性囊肿（AP）是一种位于耳前或侧面的良性、非炎症性肿胀。去顶术联合各种不同的加压方法被认为是最有效的方法。然而，术后伤口疼痛是加压治疗的主要缺点。我们引入了一种新的无痛手术方法，包括去顶术联合 Merocel® 压迫敷料。
2015 年至 2020 年，31 例 AP 患者在我们大学附属医院接受了这种新的外科压缩方法。回顾性图表审查和结果分析。
所有患者均为单侧病变，左侧病变（58.1%）多见。最常见的病变部位是舟状窝（38.7%）和耳甲腔（35.8%）。8 例（25.8%）患者的囊肿曾行抽吸或引流。仅 1 例患者在术后 3 个月后复发，接受了修正手术，无复发和不适。所有患者中，29 例（93.5%）患者的疼痛评分在数字评分量表上为 0 或 1，疼痛轻微。3 例患者有轻度瘀斑，但经保守治疗后恢复。1 例患者因术前部分软骨坏死，术后耳部轻度变形。所有患者的随访时间均至少为 6 个月。
这种新型 Merocel® 压迫敷料治疗去顶术后 AP 的方法是一种有效的方法。该方法的优点是疼痛轻微、操作简单、材料易得。
