Endoscopic dacryocystorhinostomy as treatment for lacrimal pathway obstructions: Serial case reports

Introduction: The lacrimal system is an important system for maintaining the normal condition of the ocular surface. Obstruction of the lacrimal duct can lead to inflammation and accumulation of debris and pathogens such as bacteria or fungi in the lacrimal sac and then cause dacryocystitis. This disease is often found in children or adults over 40 years of age, especially women with a peak incidence at the age of 60 to 70 years. Complaints usually include eye discomfort and redness accompanied by excessive tears. The diagnosis can be made based on physical examination, staining tests, and imaging photographs, such as dacryocystography, computed tomography (CT), and magnetic resonance imaging (MRI). Management of dacryocystitis is conservative, supportive, and surgical with an open or endonasal approach.
