Abstract:
The goal of this article is to highlight relevant diagnostic tools to assess chronic epiphora and recurrent dacryocystitis in order to avoid unnecessary diagnostic explorations. Probing of the canaliculi is important for the differential diagnosis of chronic epiphora. Surgical steps are detailed, such as the inferiorly based mucosal flap on the AGGER NASI, which is repositioned at the end of the surgery improving wound healing on the lateral wall. Potential complications are presented, as well as measures to avoid and to treat them. Long-term follow-up of 750 endoscopic DCR confirms the good results in more than 90% after endoscopic dacryocystorhinostomies in adults and in children.
