The typical histological appearance of the nasopalatine duct cyst is a thick-walled sac, with a lumen lined by both squamous and respiratory type epithelia and often sizeable neurovascular bundles (branches of the long sphenopalatine nerve and vessels) within the collagenous wall. Secondary infection and ulceration may mask the characteristic features making accurate clinical and radiographic information essential. When symptomatic or large, the cysts can be managed by simple enucleation and recurrence is rare.

The patient opted to undergo transnasal endoscopic marsupialization of the cyst and the operative steps are noted below. The patient was positioned as per the standard transnasal endoscopic surgery in the reverse Trendelenburg position. Moffett’s solution, consisting of cocaine, adrenaline, and bicarbonate, was pre-applied into the nasal cavity immediately after induction of anaesthesia in order to decongest and vasoconstrict the operative field. Endoscopic visualization using a 0-degree 4 mm rigid Hopkins rod enabled a magnified, unrestricted view of the cyst within the nasal cavity (Figure 2(A and B)). The cyst was decompressed from the left nasal cavity only as follows. After injection and hydro-dissection with Lignospan onto the nasal floor, a mucosal flap was elevated at the anterolateral aspect of the cyst and extended posteriorly along the nasal floor with a size 15 blade (Figure 2(C)). The cyst was decompressed, and the thick serous contents were suctioned out. With decompression, a clear plane was developed between the mucosal flap and the cyst wall, which was removed (Figure 2(D)). Curettage was performed on the remaining cyst lining. The mucosal flap was then replaced into the medial aspect of the cavity and Bismuth Iodoform Paraffin Paste (BIPP) ribbon was applied to help maintain the rotation of the flap into the cavity (Figure 2(E)). The right nasal cavity view after cyst decompression from the contralateral side is shown in (Figure 2(F)). The histological report confirmed a nasopalatine duct cyst with no evidence of malignancy.
