A 46-year-old woman sought treatment for pain in her maxillary anterior teeth. Physical examination revealed facial tenderness and an expanded anterior maxilla, with palatal swelling in the approximate midline. The lesion had eroded through the midline anterior palate and anterior nasal spine and had shifted the nasal floor in a superior direction. Teeth No. 8-10 tested nonvital to electrical stimulation. The lesion was dissected carefully and lifted off the nasal floor while the patient was under general anesthesia. Histologically, the lesion was cystic with an epithelial lining composed of respiratory and squamous epithelium. As a result, a nasopalatine duct cyst was diagnosed.
一名46岁女性因上颌前牙疼痛前来就诊。体格检查发现面部压痛，上颌前部膨隆，腭部中线附近肿胀。病变已侵蚀穿过腭前部中线和前鼻棘，并使鼻底向上移位。8-10号牙对电刺激无活力反应。在全身麻醉下，小心地将病变组织分离并从鼻底掀起。组织学检查显示，病变为囊性，上皮衬里由呼吸道上皮和鳞状上皮组成。因此，诊断为鼻腭管囊肿。
