canaliculoplasty
Pronunciation: kan-al-ik-yoo-loh-plas-tee
Surgical reconstruction of the tear drainage canaliculi to restore normal tear flow in cases of canalicular stenosis or trauma.
Full Definition
Canaliculoplasty involves surgical repair and reconstruction of the upper or lower canaliculi, the small tubes that carry tears from the eyelid margin to the lacrimal sac. The procedure is indicated for canalicular stenosis, trauma, or congenital abnormalities affecting tear drainage. Techniques may include balloon canaliculoplasty for stenosis, microsurgical repair for lacerations, or complex reconstruction using mucosal grafts for extensive damage. Silicone intubation is often used to maintain patency during healing.
Usage
Usage note: Specify upper vs. lower canaliculus and technique used (balloon, microsurgical repair, etc.).
