Nasopalatine Duct Cyst: Analysis of Clinico-Pathological Features & Surgical Management
Objectives: Nasopalatine duct cyst (NDC) is a non-neoplastic developmental cyst. It is the most common non-odontogenic cyst and develops exclusively in the maxilla. There is a paucity of detailed studies on its clinico-pathological behaviour and management; hence the aim of this study was to analyse its presenting features and surgical management.
Methods: A retrospective descriptive cohort analysis was conducted spanning a period of 40 years. The data included demographic details, clinical signs and symptoms and radiographic features. All lesions were confirmed histopathologically prior to inclusion. Surgical records were reviewed to identify the most suited method with the least recurrences and lowest morbidity to the patient.
Results: A total of 80 cases were included with mean age of 34 years. The majority of NDCs occurred in males (68.75%). Most NDCs (88.75%) presented in the anterior maxilla with 9 cases (11.25%) extending into the posterior maxilla as well. Swelling was noted in half of the patients while associated pain was less frequent (12.9%). Radiographically, the majority of NDCs appeared as well-circumscribed unilocular radiolucencies, while only 2 cases appeared as multilocular. NDCs appeared to be larger in patients aged 20 years and younger (mean size: 46.89mm) than other ages groups (mean size: 38.38mm). This may indicate that the lesion is more aggressive in younger individuals. Lesions with root resorption appeared with a significantly larger size. On histopathology, features of variable epithelial lining were noted. Size was the main determinant of which surgical method was chosen. NDCs that were initially biopsied, marsupialized and followed by enucleation (47.75mm) were significantly (p=0.05) larger than lesions that underwent enucleation immediately (33.98mm). No recurrences were noted.
Conclusions: NDCs were found to be larger and possibly more aggressive in younger individuals (below 20 years) in this population. The choice of surgical method was mainly determined by the size of the lesion.
