A Novel Technique to Facilitate Dacryocystectomy Using Viscoelastic Substances.

The procedure of dacryocystectomy is described in a patient with Wegener''s granulomatosis where bone preservation is essential for future reconstructive procedures. With the aid of canalicular clamps, viscoelastic substance is used to distend the lacrimal sac thereby facilitating easier dissection. We describe the use of canalicular clamping and injection of a viscoelastic substance into the lacrimal sac to facilitate easier dissection during dacryocystectomy. [ABSTRACT FROM AUTHOR]
