Lacrimal Surgery: Proposal of a New Surgical Classification of Endoscopic Dacriocystorhinostomy

Abstract

Endoscopic dacryocystorhinostomy e DCR is a well established surgical procedure with results that are equivalent to the classic open approach Although the aim of surgery is to create a direct communication between the lacrimal sac and the lateral wall of the nose by drilling out the lacrimal bone different endoscopic surgical techniques to the lacrimal sac are possible However nowadays we do not have a surgical procedure classification system In an effort to enhance scientific communication we would like to propose a surgical classification system based on the different insertion modalities of the uncinate process UP on the lacrimal bone and on the anatomical variations that may eventually require additional surgical steps
