title: Endoscopic treatment of nasolacrimal sac obstruction secondary to fibrous dysplasia of paranasal sinuses.
abstract: Fibrous dysplasia involving paranasal sinuses mostly has asymptomatic features, but sometimes may cause signs and symptoms which relate to the location and extent of bony abnormalities. The use of endoscopic nasal surgery for debulking ethmoidal fibrous dysplasia, blocking the left nasolacrimal sac and simultaneous intranasal endoscopic dacryocystorhinostomy with silicone intubation is presented. The procedure and advantages of endoscopic approach over the external approach are outlined in this paper.
