Canaliculodacryocystorhinostomy in Canalicular Obstruction

ABSTRACT

The authors performed canaliculodacryocystorhinostomy using operating microscope to resect canalicular obstruction area and reconstruct the excretory system with silicone tube insertion in patients with epiphora due to canalicular obstruction. We performed 50 operations on 44 patients with canalicular obstruction from March 1994 to December 1998. The average age of patients was 56.4 years old and the average follow-up period was 7.2 months. The canalicular obstruction site was as followsmedial common canalicular area was 13 eyes, lateral common canalicular area 20 eyes, lower canalicular area 11 eyes and upper and lower canalicular area 6 eyes. The surgical success rate was 78%. Thus authors conclude that canaliculodacryocystorhinostomy can reduce complications of a Jones tube and one can expect the physiological drainage of tears through reconstructed canaliculus.
