Dorsal, sagittal, and transverse planes were studied. Two additional skulls were also dissected following latex injection into the nasolacrimal duct. The length and width of the nasolacrimal duct and lacrimal canaliculi, and the distance between the nasolacrimal duct and the root of the upper canine tooth at the point of closest proximity were measured.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The nasolacrimal duct followed a convoluted course, particularly in the middle and rostral portions. Duct stenosis (width reduction equal to or &gt;75%) and dilations (width increase equal to or &gt;50%) were also detected, particularly in the rostral portion. Nasolacrimal duct length and width ranged from 1.3 to 1.5\u00a0cm and 1.5 to 2.3\u00a0mm, respectively. Mean lacrimal canaliculus length and width corresponded to 3.1\u00a0mm and 0.4\u00a0mm, respectively. Mean distance from the nasolacrimal duct to the canine tooth was 2.4\u00a0mm.
