The Topographic Location of The Nasolacrimal Duct as An Anatomical Reference Point for Surgical Procedures in Maxillofacial Surgery

Abstract

The study aimed to measure the distance of the nasolacrimal duct to adjacent anatomical structures in a sample of 150 CT scans from the San Ignacio University Hospital in Bogotá, Colombia, in 2021. The data was collected in a retrospective observational study based on non-probabilistic sampling. The results showed that the length of the nasolacrimal duct is greater in men than in women and decreases as age increases. The study highlights the need for studies that consider the specific characteristics of the Latin American population to establish reference points for surgical procedures in maxillofacial surgery.
