Evaluating the Prevalence of Nasolacrimal Canal Injury in Midfacial Fractures: A Retrospective CT-Based Study

Many a time, the NLA is often neglected during a routine radiographic assessment of a CT scan in patients presenting with maxillofacial injuries.

This study shows the various types of injuries to the NLA and its appearance on a CT scan. It also explains the requirement of soft tissue management and the clinical co-relationship of these injuries.
