Abstract
BackgroundTo compare the frequency of appearance of complications, anatomical success and functional success after conventional endoscopic dacryocystorhinostomies (EN-DCRs) or EN-DCR with otologic T-Type ventilation tube combined with silicone tube intubation in repeated revision cases.MethodsTwenty-two patients who had epiphora and recurrent dacryocystitis after at least a previous failed revision DCR as well as 22 patients receiving conventional EN-DCR only were enrolled in the study between January 2008 and December 2011. Operations were performed by using an otologic T-tube combined with silicone tube intubation. Oral antibiotics, nasal steroids, oral antihistamines, and antibiotic eyedrops were given to all cases. The ventilation tubes were removed 6 to 20 weeks after surgery.ResultsOf 22 cases, all cases achieved anatomical success, 19 cases were symptom free, and 3 cases had decreased continuation in complications with a functional success rate of 81.8%. The overall success rates were significantly higher than those in patients undertaking conventional EN-DCR only (P < 0.01).ConclusionThe revision endoscopic DCR has a high rate of failure. The usage of a T-type ventilation tube can significantly improve the success rate of surgery.Trial registration numberChiCTR-INR-17012160, retrospectively registered on July 27th, 2017.
Highlights
To compare the frequency of appearance of complications, anatomical success and functional success after conventional endoscopic dacryocystorhinostomies (EN-DCRs) or EN-DCR with otologic T-Type ventilation tube combined with silicone tube intubation in repeated revision cases
It has been reported that endonasal dacryocystorhinostomies (EN-DCRs) yields good esthetic, functional results and similar success rate to that of the external dacryocystorhinostomies (EX-DCRs) [1,2,3,4,5]
Modified revision EN-DCR was performed on 22 patients (7 male and 15 female), and the average age for those patients at the time of revision was 44.5 years
Summary
To compare the frequency of appearance of complications, anatomical success and functional success after conventional endoscopic dacryocystorhinostomies (EN-DCRs) or EN-DCR with otologic T-Type ventilation tube combined with silicone tube intubation in repeated revision cases. It has been reported that endonasal dacryocystorhinostomies (EN-DCRs) yields good esthetic, functional results and similar success rate to that of the external dacryocystorhinostomies (EX-DCRs) [1,2,3,4,5]. For the cases of small sac who have lacrimal sac mucosa fibrosis and mucosa scarring resulting from limited residual sac mucosa caused by previous DCRs, the success rate of revision DCR is significantly reduced. Wu et al BMC Ophthalmology (2017) 17:138 otologic T-type tube in addition to silicone tube into the lacrimal sac cavity., and we have achieved a higher success rate than conventional EN-DCR with careful treatment after surgery
