This thesis is based on a large prospective, observational study on the various factors affecting the success of endoscopic dacryocystorhinostomy (endo DCR). There are 3 components to this study. Canalicular closure has long been thought to be a major cause for early failure and the reason behind routine silicone intubation. The first component investigated the incidence of canalicular closure ...

BACKGROUND 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. METHODS Twenty-two patients who had epiphora and recurrent dacryocystitis after at least a previous failed...

AIMS To determine the efficacy of antegrade balloon dilatation of postsaccal lacrimal stenosis in adults. METHODS Balloon dilatation was performed in a series of 30 patients with complete nasolacrimal duct obstructions and epiphora. Obstruction was diagnosed by canalicular irrigation and transcanalicular endoscopic examination of the lacrimal pathway. Except for four cases in which general an...

OBJECTIVES Endonasal dacryocystorhinostomy (DCR) is a well-established treatment method in patients with nasolacrimal duct obstruction. However, there are a few reports about the overall management of failed endonasal DCR. We investigated the causes and management strategies of failed endonasal DCR. METHODS This retrospective review included 61 patients (61 eyes) who had undergone revision su...

Purpose: We explored the effects of silicone tube fixation using a nonabsorbable suture on adult nasal wall during intubation.Methods: The medical records patients (50; 54 eyes) diagnosed with nasolacrimal duct stenosis and canalicular lacerations who underwent to (using sutures) intubation from January 2019 June 2021 were followed-up for more than 3 months after surgery retrospectively investi...

The main objective of the present study was to prospectively evaluate long-term surgical success and safety in patients with nasolacrimal duct obstruction treated with a multidiode transcanalicular laser and bicanalicular silicone intubation stenting. 42 patients treated with transcanalicular laser dacryocystorhinostomy for nasolacrimal duct obstruction were prospectively enrolled. In all cases...

AIMS To utilise the improved optical qualities of newly developed lacrimal endoscopes and newly miniaturised laser fibres for diagnostic visualisation and laser surgery of the lacrimal system. METHODS A KTP laser (wavelength 532 nm, 10 W energy) was used for laser assisted dacryocystorhinostomy (DCR) with endolacrimal visualisation in 26 patients. Bicanalicular silicone intubation was placed ...

Dr. Nelson has no financial or proprietary interest in the materials presented herein. doi: 10.3928/01913913-20141230-04 It is remarkable that what appears as a straightforward ocular condition, congenital nasolacrimal duct obstruction, lacks consensus among pediatric ophthalmologists in many aspects of its management. This was clearly demonstrated in the survey by Dotan and Nelson in this issu...

To locate the proximal and distal cut ends of the canaliculus following trauma is the most difficult part of canalicular repair, especially in patients with complex acute canalicular lacerations and late presenting canalicular lacerations. Previously, irrigation and air-injection technique are reported and widely used to locate the cut ends of lacerated canaliculus. However, we have developed a...

BACKGROUND The aim of this study was to analyze clinical situations requiring rigid bronchoscopy and evaluate usefulness of rigid bronchoscopic intervention in benign or malignant airway disorders. METHODS We retrospectively reviewed 29 patients who underwent rigid bronchoscopy from November 2007 to February 2011 at St. Paul's Hospital, The Catholic University of Korea School of Medicine. R...
