Dacryoliths are often underlying contributors in cases of intermittent or chronic dacryocystitis (i.e. nasolacrimal sac inflammation, characterised by epiphora, pain, erythema, sac dilation and lacrimal punctum swelling).<\/jats:p><\/jats:sec><jats:sec id=\"S0022215111002076_sec2\"><jats:title>Objective:<\/jats:title><jats:p>We report an unusual case of dacryolith resulting in obstructive epiphora, managed via an endonasal endoscopic approach.<\/jats:p><\/jats:sec><jats:sec id=\"S0022215111002076_sec3\"><jats:title>Method:<\/jats:title><jats:p>Case report and literature review pertaining to dacryolith.<\/jats:p><\/jats:sec><jats:sec id=\"S0022215111002076_sec4\"><jats:title>Results:<\/jats:title><jats:p>A 54-year-old man attended the multidisciplinary nasolacrimal clinic due to recurrent epiphora. Obstructive epiphora secondary to chronic dacryocystitis was diagnosed. He underwent endonasal endoscopic dacryocystorhinostomy.
