Endoscopic Dacryocystorhinostomy in Primary Acquired Nasolacrimal Duct Obstruction
摘要
Endoscopic dacryocystorhinostomy (DCR) is now a well-established procedure for the treatment of nasolacrimal duct obstruction, with a success rate as high as 95.7%. It involves creating a passage of the lacrimal sac into the nose by bypassing the obstruction in the nasolacrimal duct (NLD). It is a safe, fast, and effective method to relieve a stenosis distal to the common canaliculus [2].
