The Clinical Outcome of Endoscopic Transnasal Conjunctivodacryocystorhinostomy Using MEDPOR(R) Coated Tear Drain

ABSTRACT

PURPOSE: Tube displacement, consisting of protrusion, spontaneous loss, and intrusion, is the most common cause of failure in conjunctivodacryocystorhinostomy with Jones tube. Recently, MEDPOR(R) Coated Tear Drain was designed to minimize these complications. We evaluate the surgical outcome of conjunctivodacryocystorhinostomy with MEDPOR(R) Coated Tear Drain. METHODS: Primary conjunctivodacryocystorhinostomy or revision surgery using MEDPOR(R) Coated Tear Drain was done on 23 eyes of 23 patients and the development of displacement was monitored. Thirteen patients suffered from habitual displacement of Jones tube and underwent revision surgery, while the remaining 10 underwent primary conjunctivodacryocystorhinostomy. RESULTS: During 12-month follow-up after surgery, tube intrusion was noted in one among the 23 patients. Protrusion or spontaneous loss of tube did not develop. CONCLUSIONS: The use of MEDPOR(R) Coated Tear Drain may be very effective not only for revision surgery in patients who have suffered from habitual displacement of Jones tube but also on primary conjunctivodacryocystorhinostomy.
