If present, symptoms of naso-palatine duct cyst are swelling, mainly in the anterior part of the palate, sometimes associated with pain. The cyst can easily be seen on X-ray, especially on the occlusal view. Differential diagnostic problems are mainly limited to a dentigerous cyst of a mesiodens and to periapical lesions of the central incisors. Histologically, various types and combinations of epithelial lining can be found. In the cyst wall the identification of mucous glands, nerves and large blood vessels is rather frequent. Although the histology in itself is not always very typical for a naso-palatine duct cyst, the diagnosis can almost always be made with confidence on the basis of the clinical, radiographic and microscopic features. Only if very specific or pertinent clinical features are present, is removal indicated.
如果存在，鼻腭管囊肿的症状为肿胀，主要位于腭前部，有时伴有疼痛。囊肿在X线片上很容易看到，尤其是在咬合片上。鉴别诊断问题主要局限于中切牙的含牙囊肿和根尖病变。在组织学上，可以发现上皮衬里的各种类型和组合。在囊肿壁中，黏液腺、神经和大血管的识别相当常见。虽然鼻腭管囊肿本身的组织学并不总是非常典型，但几乎总能根据临床、影像学和显微镜特征做出可靠诊断。只有当出现非常特殊或相关的临床特征时，才考虑进行切除。
