(2012) opted to use ethyl cyanoaciylate in gel form to occlude the superior lacrimal canaliculi, as the rapid polymerization of this adhesive when in liquid form resulted in it becoming stuck to the cannula and, consequently, being pulled out of the canaliculi when the needle was removed (hypodermic needle).
The histologic features of nasolabial cysts show striking similarity to the physiologically encountered epithelia in the lacrimal drainage system, specifically the lacrimal canaliculi and sac and the nasolacrimal duct that drain tear fluid from the eye to the inferior meatus of the nose (Figure 1).
The lacrimal glands secrete lacrimal fluid, which is drained by the lacrimal canaliculi into the lacrimal sac and then into the nasal cavity via the nasolacrimal duct.
