A new method using epidural catheters in the reconstruction of lacrimal drainage.

Lacrimal outflow obstruction after severance of the duct is a common problem in facial trauma. Conventional treatments include external dacryocystorhinostomy, endoscopic-assisted dacryocystorhinostomy, conjunctivorhinostomy, and a Jones tube bypass. However, the disadvantages of these methods are that the procedures are complicated and there is a high rate of recurrence. From April 2000 to March 2003, seven patients with epiphora after facial trauma had their lacrimal ducts drained with epidural catheters. The V-M shape incision was used with an epidural catheter placed as a stent for six months. After removal of the tube, all patients recovered fully from the epiphora during the follow-up period, and there were no complications.
