Endoscopic Endonasal Marsupialization of Nasopalatine Duct Cyst

Abstract

Nasopalatine duct cyst is one of the most common cysts among the nonodontogenic cysts in the maxillofacial area. This lesion usually does not show specific symptoms except for pressure from large cysts or infectious symptoms. Surgical removal including the epithelial lining is considered the treatment of choice. There are few reports of cases of endoscopic marsupialization treatment of large cysts, which have the risk of oronasal fistula. Here, we reviewed 3 cases of nasopalatine duct cyst treated with intranasal marsupialization and compared treatment results with those of conventional surgical enucleation. We suggest that endoscopic marsupialization could be used as an initial treatment option in selective cases.
