[Dacryocystorhinostomy - state of the art, indications, results].

摘要: BACKGROUND: In the ophthalmological literature external dacryocystorhinostomy (DCR) is considered gold standard for treatment of lacrimal duct stenoses. Rhinologists, on other hand, favour endonasal approach. MATERIALS AND METHODS: On basis an extensive review and our own longstanding experience we present overview causes, necessary diagnostic procedures surgical management stenosis. The outcomes two operative approaches are compared special techniques aids such as use laser, endoscopic dacryoplasty, silicone stenting, cones with stenting mitomycin C discussed. RESULTS: results published DCR slightly worse than those operation. success rates around 90 %. Laser-assisted dacryoplasty do not currently appear to yield better conventional methods. Silicone in except case presaccal There no established indications or regimens date. Postoperative care after should consist removal fibrin, crusts granulations administration eye drops (antibiotic + cortisone) nasal steroids. DISCUSSION: With appropriate technique experienced hands, practically equal classical Major advantages approach shorter operation times, lower complication reduced patient morbidity.
