Abstract
The nasopalatine duct cyst is one of the nonodontogenic epithelial cysts according to the WHO classification, and it arises from the epithelial remnants of the nasopalatine duct of the fetus.
Here we report our experience of a case of a nasopalatine duct cyst removed with the assistance of a nasal endoscopy system. A 63-year-old man presented with swelling of the right nasal vestibule. Elevation of the floor of the right nasal cavity and the bone defect of a part of the hard palate were observed. The cyst was removed by the combination of the gingival approach and nasal endoscopy system. Nasal endoscopy was useful for getting a better view of the surgical field. The patient had no postoperative complications and showed no recurrence for four years after the surgery. Because the nasal endoscopy technique is familiar to otolaryngologists, we should positively treat nasopalatine duct cysts.
