Surgical effect of the obsolete superior and inferior lacrimal canaliculi laceration

Abstract

Objective To explore the surgical effect of the obsolete superior and inferior lacrimal canaliculi laceration treated by intubating silicone double-passage annular canalicular tube via lacrimal sac.Methods The data of 12cases(12 eyes) of obsolete superior and inferior lacrimal canaliculi laceration who underwent operation of retrograde intubating silicone double-passage annular canalicular tube via lacrimal sac were retrospectively viewed.Results All patients complied with scheduled follow up more than 3 months after stent removal.Nine patients (75％) were cured entirely,2 patients (16.7％) were meliorated,and 1 (8.3％) patient had no effect.Conclusion The therapic method of retrograde intubation intubating silicone double-passage annular canalicular tube via lacrimal sac is an effective treatment for the obsolete superior and inferior lacimal canaliculi laceration.
