Retrospective analysis of 31 cases of nasopalatine duct cyst.

OBJECTIVE

To perform a retrospective analysis of patients with nasopalatine duct cysts (NPDC) in Brazil and compare with previous analyses.

MATERIALS AND

METHODS

The files of the Laboratory of Oral Pathology (Minas Gerais Federal University) from 1966 to 1997 were reviewed. Demographic, clinical and histologic data of patients with nasopalatine duct cysts were collected.

RESULTS

The mean age of patients with nasopalatine duct cysts at the time of diagnosis was 37.4 years and with a predilection for males. The majority of cases were asymptomatic. Histologically, non-keratinized stratified squamous epithelium alone or in combination with other epithelia was observed in 93% of the cases. Recurrence was not recorded.

CONCLUSION

The demographic, histopathological, radiographic, and clinical data of the NPDC in our series are similar to previous studies in other populations.
