Aim of the workTo assess the use of combined multidetector computed tomography and instillation dacryocystography (CTDCG) in detection of the level lacrimal drainage system (LDS) obstruction.MethodsTwenty-one patients with one-sided epiphora were our candidates for CTDCG. Axial source and post processing images were assessed for clear viewing and the ability to detect the level of LDS obstruction. To our knowledge, no previous studies used this combination in the assessment of the LDS obstruction.ResultsAll patients tolerated the examination well. Various levels of LDS obstruction were detected, common canaliculus in 4 (19%) patients, lacrimal sac in 3 (14.2%), junction between lacrimal sac and NLD in 9 (42.8%) and NLD obstruction in 5 (23.8%) patients. The most common CTDCG findings were dilated opacified lacrimal sac with no opacification of the nasolacrimal duct (NLD) in 9/21 (42.8%) patients. Curved planner reformation (CPR) were excellent to detect the nasolacrimal duct (NLD) obstruction.ConclusionCTDCG is a non-invasive patient friendly procedure that adds benefit in documentation and preoperative planning.
