The Application of Photosensitive Hydrogel in Intranasal Endoscopic Dacryocystorhinostomy

In the photosensitive hydrogel group, the anastomosis of the lacrimal cyst mucosal flap and the nasal mucoperiosteal flap was achieved by photosensitive hydrogel.

In the suture fixation group, the anastomosis of the lacrimal cyst mucosal flap and the nasal mucoperiosteal flap was achieved by two stitches using 6-0 absorbable wire.
