NCT07499791
Absorbable Drug-Eluting Lacrimal Sac Stent for Recurrent Chronic Dacryocystitis
This study aims to evaluate the safety and effectiveness of an absorbable lacrimal sac drug-eluting stent placed at the osteotomy site during endoscopic endonasal dacryocystorhinostomy (E-DCR) in patients with recurrent chronic dacryocystitis. The stent is composed of absorbable polymer mesh coated with mometasone furoate to reduce postoperative inflammation and adhesion, maintain ostium patency, and improve surgical outcomes. A total of 40 patients will be randomized 1:1 to receive either the absorbable stent or conventional packing with routine postoperative intranasal budesonide therapy.

The Application of Photosensitive Hydrogel in Intranasal Endoscopic Dacryocystorhinostomy
To study the effect of Photosensitive hydrogel used for suture free anastomosis of lacrimal cyst and nasal mucoperiosteal flap in endoscopic nasal dacryocystostomy, and evaluate its adhesion to lacrimal cyst and nasal mucoperiosteal flap, promoting wound healing, forming a good anastomosis, preventing postoperative anastomosis and shortening operation time. Twenty patients with chronic dacryocystitis were randomly divided into photosensitive hydrogel group and suture group.Symptoms and nasal endoscopy were followed up 2, 6, and 12 weeks after surgery for both groups. And also adverse events were recorded at each follow-up.
