OBJECTIVES/HYPOTHESIS: Nasopalatine duct cysts are the most common cystic lesion of nonodontogenic origin of the maxilla. The purposes of the study were to review the epidemiology and clinical presentation, to describe the radiographic and pathological findings, and to discuss surgical management of this entity.
Case presentations of two patients with nasopalatine duct cysts at a tertiary care institution with a review of the English medical literature from January 1960 to the present.
A 69-year-old man presented with an asymptomatic swelling of the premaxilla, and a 17-year-old woman presented with a painful swelling of the hard palate. A computed tomography scan, fine-needle aspiration, and preoperative workup were obtained in both cases. Literature was reviewed with respect to epidemiology, etiology, presentation, diagnostic studies, operative management, and recurrence rates.
Computed tomography scan demonstrated midline ovoid cystic lesions in both cases. Fine-needle aspiration of both lesions revealed no evidence of malignancy. Surgical treatment consisted of enucleation in the first case and marsupialization in the second case. Both patients did well with no evidence of recurrence. Nasopalatine duct cyst presents in the fourth to sixth decades of life with a male predilection. Recurrence rates range from 0% to 11%.
Nasopalatine duct cyst occurs in approximately 1% of the population. Presentation may be asymptomatic or include swelling, pain, and drainage from the hard palate. A well-circumscribed, round, ovoid, or heart-shaped radiolucency is seen on computed tomography. Pathological findings reveal squamous or respiratory cell types, or a combination of these, infiltrated by inflammatory cells. Enucleation is the preferred treatment with low recurrence rates.
目的/假设：鼻腭管囊肿是上颌骨最常见的非牙源性囊性病变。本研究的目的是回顾其流行病学和临床表现，描述影像学和病理学发现，并探讨该疾病的手术治疗方法。
在一家三级医疗机构中对两名鼻腭管囊肿患者的病例进行报告，并回顾1960年1月至今的英文医学文献。
一名69岁男性患者表现为前上颌骨无症状肿胀，一名17岁女性患者表现为硬腭疼痛性肿胀。两名患者均进行了计算机断层扫描、细针穿刺及术前检查。就流行病学、病因、表现、诊断研究、手术治疗及复发率等方面对文献进行了回顾。
计算机断层扫描显示两名患者均有中线卵圆形囊性病变。对两个病变进行细针穿刺均未发现恶性证据。第一例患者采用囊肿摘除术，第二例患者采用袋形缝合术。两名患者术后恢复良好，均无复发迹象。鼻腭管囊肿好发于40至60岁人群，男性居多。复发率为0%至11%。
鼻腭管囊肿在人群中的发病率约为1%。其表现可能无症状，或包括肿胀、疼痛及硬腭溢液。计算机断层扫描可见边界清晰的圆形、卵圆形或心形透光区。病理检查结果显示为鳞状或呼吸细胞类型，或二者兼有，并伴有炎症细胞浸润。囊肿摘除术是首选治疗方法，复发率低。
