Answer

Individuals with brachycephalic heads have a higher incidence of dacryocystitis than dolichocephalic or mesocephalic skulls. This is because brachycephalic skulls demonstrate a narrower diameter of inlet into the nasolacrimal duct, the nasolacrimal duct is longer, and the lacrimal fossa is narrower. Furthermore, patients with a flat nose and narrow face are at a higher risk for developing dacryocystitis, presumably because of the narrow osseous nasolacrimal canal.

In 1883, Nieden noted a 9% incidence of hereditary lacrimal excretory system inflammation. This is significantly higher than what has been found by the author in studies.
