purpose: to evaluate the effect of stenosis nature on success of silicone intubation for nasosolacrimal duct stenosis (nlds) in adults (patent nasolacrimal duct with resistance to positive-pressure irrigation) methods: an interventional case series of consecutive monocanalicular and bicanalicular silicone intubation for nasolacrimal duct stenosis in adults were reviewed. the severity of the ste...

purpose: to assess the efficacy of intraoperative mitomycin c (mmc) during silicone intubation (si) as a substitute for dacryocystorhinostomy (dcr) in nasolacrimal duct (nld) obstruction. methods: in a prospective, randomized, double-blind study, 88 candidates of dcr for nld obstruction were randomly assigned into two groups of si with application of either mmc (0.2 mg/ml for 2 minutes) or plac...

The role of silicone intubation in routine dacryocystorhinostomy (DCR) surgery remains unclear. Recent studies provide a higher level of evidence against intubation in DCR. Intubation of the nasolacrimal duct with silicone tubes has largely arisen as a result of history, anecdote and the evolution of DCR surgery rather than being based upon sound evidence. Silicone intubation has gained popular...

PURPOSE To evaluate prognostic factors affecting silicone tube intubation outcomes in Asian patients with lacrimal drainage system stenosis. METHODS A retrospective review was conducted on the medical records of 822 patients (1,118 eyes) who had undergone silicone tube intubation to treat lacrimal drainage system stenosis between January 2011 and December 2012. Patients were divided into two ...

purpose: to evaluate the success rate of bicanalicular silicone tube intubation in children with congenital nasolacrimal duct obstruction (cnldo). methods: hospital records of 71 cases of bicanalicular silicone intubation in 62 children with cnldo were reviewed. success was defined as resolution of symptoms and signs such as epiphora and discharge 6 months after removal of the silicone tube. re...

purpose: to compare success rates of external dacryocystorhinostomy (dcr) with and without bicanalicular silicone intubation for management of primary acquired nasolacrimal duct obstruction. methods: in a randomized clinical trial study, 52 patients with primary acquired nasolacrimal duct obstruction underwent external dcr. patients were randomly enrolled into two groups. in the 1st group, exte...

PURPOSE To investigate the efficacy of lacrimal silicone intubation for the management of epiphora in patients who have previously undergone anatomically successful dacryocystorhinostomy (DCR). METHODS The authors recruited 13 patients (4 male, 9 female) who had persistent epiphora after an anatomically successful primary external DCR and conducted lacrimal silicone intubation through the dac...

purpose: to compare the success rate of external dacryocystorhinostomy (dcr) with and without bicanalicular silicone intubation for the management of primary acquired nasolacrimal duct obstruction. methods: in this study, 51 eyes from 50 patients who were diagnosed with primary acquired nasolacrimal duct obstruction underwent external dcr. patients with history of trauma and/ or surgery in the ...

PURPOSE To compare the clinical effects of the single wide-diameter bicanalicular silicone tube and the double bicanalicular silicone tube in endonasal dacryocystorhinostomy (DCR) with canalicular trephinization for canalicular obstruction. METHODS We retrospectively reviewed the records of 121 patients with monocanalicular or common canalicular obstruction who had undergone endonasal DCR wit...

Background: A purposely designed wire reinforced silicone tube is available for tracheal intubation through intubating laryngeal mask airway (ILMA). However, this tube is expensive and not always available. Hence, cheaper and readily available alternatives such as conventional polyvinyl chloride (PVC) endotracheal tube should be evaluated for intubation through ILMA. Methods: After informed con...
