Abstract：
Nasopalatine duct cyst (NPDC) is the most common nonodontogenic cyst originating from the epithelial remnants of the incisive canal in the maxilla. NPDC is treated with complete enucleation via a sublabial or transpalatal approach, and recently tranasnasal endoscopic marsupialization has been gradually used. However, in large and extensive cases, it is difficult to remove the cyst completely, and there is a high risk of postoperative complications, including oronasal fistula. Therefore, tranasnasal endoscopic marsupialization is recommended as an effective treatment modality. Herein, we report a case of a 49-year-old man with a very large NPDC with a maximum diameter of 58 mm. NPDC was successfully managed by transnasal endoscopic marsupialization under general anesthesia without any major problems. No postoperative complications or recurrence occurred until 12 months postoperatively. Transnasal endoscopic marsupialization for large NPDC is minimally invasive and useful.
摘要：
鼻腭管囊肿（NPDC）是最常见的非牙源性囊肿，起源于上颌骨切开管的上皮残留物。NPDC通过阴唇下或跨鼻入路进行完全摘除治疗，最近经鼻内镜袋状化已逐渐使用。然而,在大型和广泛的情况下，很难完全切除囊肿,术后并发症的风险很高，包括口鼻瘘.因此,经鼻内镜袋式治疗是一种有效的治疗方式。在这里，我们报告了一例49岁男性患者的NPDC非常大，最大直径为58mm。NPDC在全身麻醉下经鼻内镜有袋形治疗成功，没有任何重大问题。术后12个月无并发症及复发。经鼻内镜造袋化对年夜型NPDC具有微创和有用性。
