Objectives The purposes of this study were to investigate Computed tomography(CT) imaging findings and clinical symptoms of Nasopalatine duct cyst(NPDC), and to elucidate morphological features of NPDC affects the clinical symptoms.
Study Design The study included 37 patients(24 males, 13 females; age mean 43.8,range12-83)with a confirmed histopathologic diagnosis of NPDC between April 2006 and October 2016. Analysis of spread of cyst and maximum diameter of NPDC were performed on the CT images. Diagnosis of symptoms were made based on clinical interview. Spread of cyst and maximum diameter were compared between patients with and without symptoms using the Mann-Whitney U test. Receiver-operating characteristic(ROC)curve analysis was performed to assess the ability of maximum diameters to predict symptoms.A P-value＜0.05 was considered to indicate statistical significance.
Results Spread of cyst and maximum diameter of NPDC patients with symptoms were significantly higher than that of patients without symptoms(p＜0.05). The accuracies with pain(≥23.9 mm), swelling(≥14.1 mm), and drainage(≥28.6 mm)were 62%, 70% and 73%,respectively.
Conclusions This study suggested that morphological features of NPDC affects the clinical symptoms. The spread and maximum diameter of NPDC using CT can help predict clinical symptoms.
