ABSTRACT

Evaluation of Nasolacrimal Canal for age and gender assessment

INTRODUCTION – Age and Gender estimation is an indispensable component of biological assessment in forensic science.  There are certain skeletal remains which can guide forensic experts toward accurate identification; one such can be human skull. Among many anatomical landmarks, the nasolacrimal canal is one of the prominent landmark of the craniofacial region. It is 12- 18 mm long canal that drains into the nasal cavity. Computed tomography is an important tool that is preferred due to its low cost, high resolution, lower dose of radiation and better image quality than CBCT. Nasolacrimal canal can be well evaluated routinely on computed tomographic examination.

AIM – Evaluation of nasolacrimal canal for age and gender assessment.

MATERIALS AND METHOD -   This study was carried out on 300 axial CT scans which included images of subjects above 15 years of age. The anteroposterior and transverse diameters along with sectional area of the bony nasolacrimal canal at the level of infraorbital margin, and the angle between the bony canal and the nasal floor were evaluated for age and gender determination.

RESULTS – Except for the length, all other four dimensions of the nasolacrimal canal were found to be highly statistical significantly greater in males (p < 0.001). On comparison between right and left side, all the five dimensions of nasolacrimal canal, there was found to be no statistical significant difference.

CONCLUSION - Nasolacrimal canal is one of the reliable landmark for gender assessment.
