- Abstract
Introduction: Nasopalatine duct cyst is a non-odontogenic cyst of unknown and widely discussed etiology. Its formation probably occurs due to spontaneous or triggered proliferation of nasopalatine duct epithelial cells. It is estimated that 1% of the population can develop this injury. A detailed anamnesis and complementary imaging exams are valuable to guide a therapeutic approach in cases of this lesion, since clinically and radiographically it can be mistaken by other radiolucent pathologies occurring as a well-defined radiolucent area above incisors in anterior maxilla. Objective: To report and discuss a case of nasopalatine cyst diagnosed and treated at the school Ambulatory of Arthur Sá Earp Neto University Center. Case report: A 32-year-old male patient attended to a routine dental appointment and, on a panoramic radiograph complementary to the clinical examination, it was possible to observe a well-defined radiolucent lesion above the upper incisors in the maxillary midline. Initial hypothesis was a nasopalatine duct cyst. Thus, a cone beam computed tomography was requested to a better evaluation of size and location of the lesion that was removed surgically by the enucleation technique. The cyst was fully removed, in a careful approach due to preservation of its capsule, adhered to the periosteum by the capsule, and its removal was performed carefully. Then, the specimen was sent for histopathological analysis, that exhibited a cystic cavity revested by squamous stratified epithelium with variable number of layers, which was compatible with nasopalatine duct cyst diagnosis. At one year after surgery, patient returned for radiographic and clinical follow-up and exhibited new bone formation, thus being discharged. Conclusion: Nasopalatine duct cyst is an unusual benign lesion of unknown etiology, which can lead to complications if it is not well diagnosed. A detailed investigation of the patient's medical history and complementary exams are fundamental to an appropriate treatment and favorable prognosis.
