코막힘이 주증상인 코입천장관낭 2예

The nasopalatine duct cyst (NPDC) is the most common cyst of nonodontogenic origin in the maxilla. In most NPDC cases, patients are not aware of any marked clinical symptom and NPDC is therefore usually detected during routine clinical or radiographical examination. In large cysts, swelling is present at the bottom of the anterior nasal cavity as well as at the midline of the palate. The treatment of choice is enucleation of cyst. We experienced two cases of nasopalatine duct cyst with nasal stuffiness symptom and elevated nasal floor, which were confirmed to be a NPDC after surgical treatment. We report this cases with a review of literatures. (J Clinical Otolaryngol 2007;18:233–236)
