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.
鼻腭管囊肿（NPDC）是最常见的非牙源性囊肿，起源于上颌切牙管的上皮残余。NPDC通过唇下或经腭入路进行完整摘除治疗，近来经鼻内镜袋形缝合术已逐渐被采用。然而，对于巨大且范围广泛的病例，完全切除囊肿很困难，且术后并发症风险高，包括口鼻瘘。因此，推荐经鼻内镜袋形缝合术作为一种有效的治疗方式。在此，我们报告一例49岁男性患者，患有一个最大直径达58毫米的非常大的NPDC。在全身麻醉下通过经鼻内镜袋形缝合术成功治疗该NPDC，未出现任何重大问题。术后12个月内未发生术后并发症或复发。经鼻内镜袋形缝合术治疗巨大NPDC具有微创性且有效。
