title: [Endoscopic sinus surgery for a paranasal sinuses mucocele with light guide and dacryoendoscopy].
abstract: It is hard to cure dacryocystitis caused by a paranasal sinus mucocele with treatment which only targets the mucocele. Also, it is difficult to identify the lacrimal sac and the nasolacrimal duct preoperatively and intraoperatively when the lacrimal passage is markedly changed by the mucocele or previous surgery. We experienced four cases of mucocele complicated by lacrimal stenosis or obstruction. We performed marsupialization of the mucocele and direct silicon intubation or endoscopic dacryocystorhinostomy simultaneously with the use of a fiberoptic illuminator or dacryoendoscopy. Assisted by those devices, lacrimal procedures can now be done quickly and safely regardless of the surgeon's experience. In addition, performing surgeries both for the lacrimal passage and for the mucocele at the same time can minimize the burden on patients.
