Evaluation of treatment modalities and prognostic factors in children with congenital nasolacrimal duct obstruction

Nasolacrimal duct intubation in the treatment of congenital nasolacrimal duct obstruction in older children

“…5 Nasolacrimal duct silicone intubation is generally reserved for patients with persistent obstruction after failed probing or as a primary method in older children. 6 The procedure has been used to reduce the need for dacryocystorhinostomy (DCR). It has been displayed that nasolacrimal duct intubation is a successful procedure in children aged up to 7 years.…”

A prospective, randomised comparison of probing versus bicanalicular silastic intubation for congenital nasolacrimal duct obstruction

“…Age is considered a risk factor by many authors as the success rate declines after 2 years of age 2 8 9 12 20. However, other studies,1 3 10 including ours, did not consider age as a risk factor for probing.…”

“…Some have encouraged silastic intubation as a primary procedure despite the fact that probing has lower complications and is relatively easy to perform 2 8–14. Reasons for encouraging silastic intubation include declining success rates of probing with age and successful silastic intubation after a failed probing.…”

“…Reasons for encouraging silastic intubation include declining success rates of probing with age and successful silastic intubation after a failed probing. However, comparison of these procedures is tenuous at best as much of the published literature is based on retrospective studies, differing selection criteria, varying age of the study cohorts, and variable outcome measures 1 2 4 6 8 15. A fair number of previous studies are prospective, but none is comparative or randomised 5 7 10 12 16 17…”

Einfluss des Operationszeitpunktes auf den langfristigen Erfolg von Tränenwegsoperationen mit Schlauchintubation bei kindlicher Tränenwegsstenose

“…Im Falle eines konservativen Therapieversagens gilt die TWS mit S als Therapie der Wahl [3,12]. Neuere Untersuchungen zeigen ihre Überlegenheit gegenüber der einfachen Tränenwegsspülung ohne anschließende Schlauchintubation [18,19]. Aufgrund der bei Kindern sehr engen Verhältnisse unter der unteren Nasenmuschel kann es im weiteren Verlauf nach Spülung ohne anschließende Intubation zu einer Re-Stenosierung durch narbigen Wiederverschluss der Hasner-Membran kommen.…”
