Effect of intubation in patients with functional epiphora after endoscopic dacryocystorhinostomy

AIM: To investigate the effect of bicanalicular silicone tube intubation (BSTI) in treatment functional epiphora after endoscopic dacryocystorhinostomy (En-DCR). METHODS: Clinical data 84 patients (95 eyes) with En-DCR were retrospectively analyzed. Functional was confirmed as persistent or recurrent by fluorescein dye disappearance test (FDDT), lacrimal irrigation test, well examination. Secondary BSTIs recommended for epiphora. These tubes removed 1mo surgery. success and associated complications assessed 2y follow-up. RESULTS: Seven (9 refused intervention, 5 (6 did not complete postoperative follow-up, 1 patient (1 eye) developed prolapse within Seventy-one (79 included at last. ratios six months, one year, two years post-operation 94.9% (75/79), 92.4% (73/79), 91.1% (72/79), respectively. Three eyes presented punctal slitting (2 without epiphora), eye proximal canaliculus slitting, stenosis 4 still present detectable abnormal last CONCLUSION: is an effective procedure low recurrence probability En-DCR. Punctal injury are main tube-associated secondary intubation.
