Two Cases of Epiphora Following Le Fort I Osteotomy / 대한이비인후과학회지

The lacrimal drainage system begins at the puncta and empties through the valve of Hasner into the inferior meatus. The varieties of the anatomic location, size and morphology of this valve can predispose susceptible individuals to an increased incidence of iatrogenic injury during nasal surgical procedures, thus necessitating a comprehensive understanding of the system. We report two cases of epiphora following two-jaw surgeries for cosmetic purposes. Nasolacrimal duct obstructions were diagnosed, and the symptoms were improved with dacryocystorhinostomies.
