STUDY OBJECTIVE In inoperable patients with tracheal stenosis who are treated using silicone stents, stent migration occurs in 18.6% of cases. To decrease the migration rate, we have designed a new silicone stent with narrow central and larger distal parts. This study analyzes the stability and tolerance of this new stent. DESIGN Preliminary prospective study conducted in two French universit...

Objective: To determine the effectiveness of an autostable bicanaliculus Intubation stent in management acquired punctal stenosis adults.Study Design: Quasi-experimental study.Place and Duration Study: The study was carried at Armed Forces Institute Ophthalmology (AFIO), Rawalpindi, Pakistan, from April 2022 to November 2022.Materials Methods: This is being conducted after approval hospital eth...

AIM To determine the long term success of external dacryocystorhinostomy (DCR) in adults with acquired partial nasolacrimal obstruction. METHODS A retrospective study of 50 external dacryocystorhinostomies with silicone intubation performed for partial nasolacrimal obstruction, was undertaken. Preoperative lacrimal scintigraphy divided drainage abnormalities into presac or postsac delays. Pos...

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...
