Nasopalatine duct cyst

Nasopalatine Duct Cyst (also known as Incisive Canal Cyst) is the most common non-odontogenic cyst of the oral cavity. It is a developmental cyst that originates from the remnants of the nasopalatine duct.

Etiology

The exact cause of the Nasopalatine Duct Cyst is unknown. However, it is believed to be associated with the remnants of the nasopalatine duct, which is a canal connecting the oral and nasal cavities in the embryonic stage. The duct usually disappears by birth, but its remnants can give rise to the cyst.

Clinical Features

The Nasopalatine Duct Cyst is usually asymptomatic and is often discovered during routine radiographic examination. When symptoms do occur, they may include swelling in the anterior palatal region, pain, nasal obstruction, and sometimes drainage.

Diagnosis

Diagnosis of the Nasopalatine Duct Cyst is primarily based on radiographic findings. The cyst typically appears as a well-defined radiolucent area in the midline of the maxilla, between the roots of the central incisors. Additional diagnostic tools may include biopsy and histopathological examination.

Treatment

Treatment of the Nasopalatine Duct Cyst typically involves surgical removal of the cyst. The prognosis following treatment is generally excellent, with a low recurrence rate.
