Purpose: To examine the clinical outcome of the ballon dilatation or stent implantationin stenosis and obstruction of the nasolacrimal system.
Method: Between 01.03.1999 and 26.3.2003 54 patients with epiphora and proven obstruction of the nasolacrimal system by dacryocystography were treated with ballon dilatation or stent implantation in local anaesthesia. In 39 cases there was a pre- or postsaccal stenosis, in 3 cases an occlusion of the canaliculus communis, in 12 cases a postsaccal occlusion. The intervention was followed by a one-week period of additional treatment wirh antiinflammatory and antioedematous eye-drops. All patients were treated elective.
Results: In 36/39 patients with stenosis the balloon dilatation was technically successful, in 3 patients the guide wire could not be placed in the nose cavitiy. With occlusion 11/15 patients were technically succesfull, 3/3 had a short postsaccal occlusion. In 2 cases it came to an epistaxis. Over a mean follow-up of 6 months there was in 4/8 long postsaccal occlusions and in 1/3 short occlusions a reocclusions. In 4/12 patients with long occlusions a s
