Diagnosis And Management Of Nasopalatine Duct Cyst: A Report Of Two Cases And Literature Review, Feiyi Sun Dds, Harry Dym Dds

The New York State Dental Journal

The nasopalatine duct cyst (NPDC) is one of the most common non-odontogenic, non-neoplastic developmental cysts. It arises from the epithelial remnants of the nasopalatine duct within the incisive canal and crosses the midline of the anterior maxilla. Most cases are asymptomatic and either are discovered by chance on radiographs or present as a soft tissue swelling, pain, or drainage in the palate. The present study describes the diagnosis and surgical management of two NPDC cases at the Department of Oral and Maxillofacial Surgery at the Brooklyn Hospital Center.
