Nasopalatine

Nasopalatine duct cyst is the most common non-odontogenic cyst of the oral cavity, occurring in the midline of the anterior maxilla. It is believed to originate from the remnants of the nasopalatine duct, which is an embryonic structure connecting the oral and nasal cavities.

Etiology

The exact cause of nasopalatine duct cyst is unknown. However, it is believed to be associated with the remnants of the nasopalatine duct. Some researchers suggest that trauma or infection may trigger the cyst formation.

Clinical features

Nasopalatine duct cysts are usually asymptomatic and are often discovered during routine radiographic examinations. When symptoms do occur, they may include swelling in the anterior maxillary region, pain, and sometimes nasal obstruction.

Diagnosis

The diagnosis of nasopalatine duct cyst is usually made based on clinical and radiographic findings. Radiographically, the cyst appears as a well-defined radiolucent area in the midline of the anterior maxilla. Sometimes, the cyst may be confused with other conditions such as periapical cyst or incisive canal cyst.

Treatment

The treatment of choice for nasopalatine duct cyst is surgical enucleation. The cyst is completely removed and the area is allowed to heal. In some cases, marsupialization may be performed to reduce the size of the cyst before enucleation.

Prognosis

The prognosis for nasopalatine duct cyst is generally good. Recurrence is rare after complete removal of the cyst.
