Endoscopic Dacryocystorhinostomy Following Nasolacrimal Drainage System Trauma and Medial Orbital Wall Reconstruction

Case series. To describe the assessment and surgical approach to dacryocystorhinostomy (DCR) for patients with nasolacrimal duct obstruction (NLDO) in the presence of orbital wall hardware. The pre-operative assessment, management and outcomes of two patients with secondary acquired NLDO following medial orbital wall fracture repair treated by nasal endoscopic DCR. Anatomical and functional success was achieved in both cases at 6 weeks post operatively without disruption of the orbital plate. There was persistent success at 1 and 3 years’ post-operatively. Endoscopic DCR is a good option for the treatment of NLDO in patients with previous medial orbital wall fracture repair where the location of the plate may complicate the external approach.
