Journal Title: Eye Science (Yanke Xuebao) - Year 2025, Vol 40, Issue 1
Abstract
[Objective:] To study the efficacy and safety of endonasal endoscopic lower position dacryocystorhinostomy(En-LP-DCR) combined with new RT lacrimal stent intubation for treating chronic dacryocystitis. [Methods:] In A prospective randomized controlled study, patients with chronic dacryocystitis secondary to primary nasolacrimal duct obstruction who met the inclusion criteria were randomly divided into two groups. In study group (Group A), 43 cases (44 eyes)were treated with the En-LP-DCR combined with new RT lacrimal stent intubation. Control group (Group B), 39 cases (39 eyes): conventional endoscopic dacryocystorhinostomy combined with bicanalicular intubation. The stent was removed from 3 to 6 months after surgery and followed up 6 to 12 months. [Results:] There was no recurrence of chronic dacryocystitis in both groups. In group A, 42 eyes (95.45%) were cured and 2 eyes (4.54%) were improved. In group B, 38 eyes were cured (97.43%) and 1 eye was improved (.56%), there was no significant difference between the two groups (P > 0.05). In group B, 12 eyes (30.77%) With the incorporation of powered instrumentation to make bony ostium with full exposure of the lacrimal sac., while group A did not use powered dynamic system. Operation time of group A was (31.88±1.64) min; The operation time of group B was (48.54±4.40) min. The difference between the two groups was significant (P< 0.01). In group B, the stent dislocated from the medial canthus in 2 cases, while in group A, there were no cases of the stent dislocated. No patient with dislocation, displacement of stent and punctum erosion founded in both groups, and no recurrence of chronic dacryocystitis was observed during the average follow-up of 6 months. [Conclusion:] Endonasal endoscopic lower position dacryocystorhinostomy combined with new RT lacrimal stent intubation is a new and effective method for the treatment of chronic dacryocystitis, with minimally surgical injury and faster postoperative recovery.
