Methods A total of 150 sagittal dry bones in the Department of Anatomy, Faculty of Medicine, Istanbul University were evaluated. The length and the width at diferent points of the nasolacrimal canal were calculated. According to the widths of the nasolacrimal canal ten diferent morphological types were revealed. Results The length of the canal was found as mean 13.62±2.42 mm on the right and 12.44±2.68 mm on the left side. The entrance, the base, the upper and the lower thirds of nasolacrimal canal were 6.22±1.19 mm, 7.95±1.85 mm, 5.85±1.06 mm, 6.60±1.54 mm, on the right and 6.08±1.16 mm, 7.24±1.64 mm, 5.45±1.29 mm, 6.23±1.48 mm, on the left side, respectively. The width of the entrance of the nasolacrimal canal was the narrowest width compared to the base, upper and lower thirds in 7/10 types of 71/150 cranial bones. Conclusion This comprehensive morphological classifcation of the nasolacrimal groove sheds new light on its complex variations. We support that the fnding of this study has the potential to improve the precision of diagnostic assessments and guide specifc therapeutic interventions for patients with lacrimal drainage disorders.eninfo:eu-repo/semantics/closedAccessNasolacrimal DuctHuman SkullLacrimal DrainageMorphologyNasolacrimal GrooveArticle10.1007/s00276-024-03311-2465559566Q3WOS:0011692009000012-s2.0-85187273728PMID: 38393369Q2
