Does Bicanalicular Intubation Improve the Outcome of Endoscopic Dacryocystorhinostomy?

Unlabelled: The aim of this study was to compare the success of endoscopic dacryocystorinostomy with and without bicanalicular intubation in the treatment of distal nasolacrimal duct obstruction.

Methods: In a prospective, randomized, comparative study, endoscopic dacryocystorinostomy without bicanalicular silicone intubation (Group I) and endoscopic dacryocystorinostomy with intubation (Group II) were performed in patients with distal nasolacrimal duct obstructions. The tubes were removed 3 months after surgery in Group II, and the patients were followed up for 6 months after surgery.

Lacrimal sac dacryoliths (86 samples): chemical and mineralogic analyses.

Background: Because dacryoliths occur at low frequency, few studies have focused on their composition. We aimed to present findings from morphological, chemical, and mineralogic analysis of 86 dacryoliths.

Methods: We studied 86 dacryoliths obtained during 832 dacryocystorhinostomies (DCR) performed for postsaccal obstruction.

Lacrimal sac dacryolith (76 cases): a predictive factor for successful endonasal dacryocystorhinostomy?

To evaluate whether the presence of dacryolith is a predictive factor for successful dacryocystorhinostomy. The success rate of endonasal dacryocystorhinostomy (EDCR) performed to relieve obstruction of the nasolacrimal duct was evaluated according to the presence of dacryolithiasis. The surgical results of patients with (group I) and without dacryoliths (group II) were analysed and compared 1-year post surgery.

Monocanalicular versus bicanalicular intubation in the treatment of congenital nasolacrimal duct obstruction.

Background: To compare the success rate of monocanalicular intubation (MCI) compared with bicanalicular silicone intubation (BCI) in congenital nasolacrimal duct obstruction (CNLDO) in infants and toddlers.

Methods: In a prospective, nonrandomized, comparative study, MCI (n = 35 eyes) through the inferior canaliculus or BCI (n = 35 eyes) were performed under general anaesthesia in children aged 10 to 36 months with CNLDO. The tubes were removed 3-4 months after tube placement, and the children were followed up for 6 months after the removal of tubes.

Conjunctivocystorhinostomy with Jones tube--is it the surgery for children?

Background: To present experience with conjunctivocystorhinostomies (CDCR) at pediatric age.

Methods: Operative and postoperative data were collected for 15 pediatric CDCRs (aged 9 to 14.5 years) performed endonasally.

Primary pediatric endonasal dacryocystorhinostomy--a review of 58 procedures.

Objectives: The objectives of this study are to report the outcomes of pediatric patients with lacrimal system obstruction who underwent primary endoscopic dacryocystorhinostomy (EDCR).

Study Design: The authors conducted a retrospective noncomparative case series.

Methods: The operative and postoperative data have been collected in 58 children aged between 3 months and 13 years (mean 4.

Does the length of intubation affect the success of treatment for congenital nasolacrimal duct obstruction?

Purpose: To compare success rates of intubation for 2 versus 5 months in congenital nasolacrimal duct obstruction in children between 15 and 30 months of age.

Methods: This prospective, randomized study evaluated drainage function in 145 eyes of children aged between 15 and 30 months and treated for congenital nasolacrimal duct obstruction using silicone stents with the fluorescein dye disappearance test. The tubes were removed 2 months (group I, 48 eyes) and 5 months (group II, 47 eyes) after stent placement.

Pediatric endonasal dacryocystorhinostomy: a report of 34 cases.

Objectives: To present experience with the endoscopic dacryocystorhinostomies (EDCR) at the pediatric age.

Study Design: Case series, clinical study.

Methods: The operative and postoperative data have been collected in 34 pediatric EDCRs (mean age 4.

Conjunctivodacryocystorhinostomy tube placement with a urologic catheter.

In an endoscopically performed conjunctivodacryocystorhinostomy, insertion of a Jones glass tube can be difficult if the nasal end of the tube draws soft tissue around the tunnel in front of the tube. A urologic Tiemann catheter has been used for Jones tube placement in 44 cases since 2001. The tube is put in the lumen end of the catheter, the tip of which is bulbous and gradually tapered in its diameter.
