Abstract
Nasopalatine duct cyst is a nonodontogenic cyst that arises from the remains of the nasopalatine duct. It is comparatively rare among all cysts of the maxilla.
A 29-year-old male visited our clinic because of an increasing anterior midline palatal mass. MR imaging showed a large cystic lesion, which was 32 mm in diameter, arising within the nasopalatine duct. After removal of the cyst, a large dead space remained. It was reconstructed with autogenous cancellous bone of the iliac crest. At the time of 6 months after the surgery, 3 dimensional CT demonstrated good contour of the palatal bone. Autogenous cancellous bone is very useful and reliable material for the reconstruction of palatal bone defects.
