The aim of this study was to find an effective treatment method for preauricular sinus (PAS) in the pediatric population. We also investigated if the prognosis of treatment differed according to the location of the PAS.
From May 2015 to April 2020, a retrospective chart review was conducted on pediatric patients who underwent surgical excision of PAS at a tertiary referral medical center. Patients were divided into classical and variant groups according to the location of the PAS. The recurrence and postoperative complications, along with the preoperative history, were confirmed through medical chart review.
A total of 88 patients (112 ears) were included in the study (n = 77 in the classical group and n = 11 in the variant group). The mean age of the patient was 6.5 years, and there were 48 males and 40 females. To reduce recurrence after surgical treatment, a temporalis muscle fascia anchoring suture was used in combination with preoperative pit dye staining, probe use, and surgical microscopy. The overall recurrence rate was 2.4% (2 cases), and postoperative minor complications were chronic pain (4.5%, n = 4), minor skin inflammation (10.2%, n = 9), and subcutaneous suture knot discomfort (13.6%, n = 12). Between the classical and variant groups, no clinical differences such as recurrence rate or complication rate were found, except for the long hospitalization period in the variant group (p = 0.043).
The use of a temporalis muscle fascia anchoring suture in combination with pit dye staining, probe use, and surgical microscopy in pediatric patients with PAS showed relatively low recurrence and complication rates compared to what has been previously reported in the literature. PAS in the variant position did not affect prognosis.
本研究旨在寻找一种治疗儿童先天性耳前窦（PAS）的有效方法。我们还研究了 PAS 位置是否会影响治疗效果。
回顾性分析 2015 年 5 月至 2020 年 4 月期间在某三级转诊医疗中心接受 PAS 外科切除手术的儿科患者。根据 PAS 的位置将患者分为经典型和变异型两组。通过病历回顾，确认了复发和术后并发症以及术前病史。
共有 88 例患者（112 耳）纳入本研究（经典组 n=77，变异组 n=11）。患者平均年龄为 6.5 岁，其中男 48 例，女 40 例。为了降低外科治疗后的复发率，我们采用了颞肌筋膜锚定缝合，并结合术前皮丘染色、探针使用和手术显微镜。总的复发率为 2.4%（2 例），术后轻微并发症有慢性疼痛（4.5%，n=4）、轻微皮肤炎症（10.2%，n=9）和皮下缝线结不适（13.6%，n=12）。在经典型和变异型组之间，除了变异型组的住院时间较长（p=0.043）外，未发现复发率或并发症率等临床差异。
与文献报道的结果相比，在儿童 PAS 患者中使用颞肌筋膜锚定缝合，并结合皮丘染色、探针使用和手术显微镜，复发率和并发症率相对较低。变异型 PAS 位置并不影响预后。
