| Popis: | Epiphora (watering eye) is generally caused by insufficient drainage of tears. The most common cause of epiphora in adults is idiopathic inflammatory obstruction of the nasolacrimal duct. The traditional surgical treatment of nasolacrimal duct obstruction is an external dacryocystorhinostomy, which has an 85% to 95% success rate. To eliminate cutaneus wounds and scarring some techniques were introduced, for example the endonasal laser dacryocystorhinostomy and the nasolacrimal stent. The aim of this report was to evaluate the first case of nasolacrimal stent implantation in Brazil. The procedure was performed in the "Hospital das Clinicas" of the University of Sao Paulo - USP. A female patient with tearing of the right eye and secretion was submitted to a nasolacrimal stent implantation, with fluoroscopic guidance. The stent used in this procedure was the polyurethane Tearleader stent set. (Dr. Wilhelm type-PBN MEDICALS - Denmark). After 3 months, the patient started complaining of tearing, so the stent was removed and the patient was submitted to an external dacryocystorhinostomy. At present the patient does not have any symptoms or complaints. This procedure is less invasive and simple, causes no facial scars and avoids surgical trauma, but the long term success rates achieved using polyurethane nasolacrimal stents are low as compared with the external dacryocystorhinostomy. In addition, the patients usually complaint of tearing even having patent lacrimal system. In summary, long-term studies are needed to resolve some complications. Maybe a new stent design and new methods of unblocking the stent in situ would improve in the near future the levels of patency that currently are modest. |
