Nasal vestibular cysts are cystic masses located at the subcutaneous base of the nasal vestibule, anterior and lateral to the pear-shaped foramen, within the soft tissue of the superficial surface of the alveolar process of the maxilla. They can be divided into retention cysts and bulbomaxillary cysts that develop from residual epithelium from the embryonic period. Nasal vestibular cysts occur subcutaneously at the base of the nasal vestibule, outside before the pear-shaped foramen, within the soft tissue of the superficial surface of the maxillary alveolar process. The disease is more frequent in middle-aged women, with the onset of the disease mostly in the 30-50 age group.
