Trans Canalicular Endoscopic Laser-Assisted Dacryocystorhinostomy
摘要
Trans canalicular endoscopic laser dacryocystorhinostomy (DCR) involves the creation of an opening between the lacrimal sac and the nasal cavity using a trans canalicular laser fibre [1]. Trans canalicular or the endo canalicular approach was first described by Jack in 1963. He introduced a probe through the lower punctum via the canaliculus into the lacrimal sac [2, 3]. The laser DCR was first described by Massaro et al. in 1990 in an attempt to achieve precise bone removal with meticulous hemostasis [4].
