Intranasal endoscopic identification of the nasal septal L-strut: a cadaveric study.

Suggested landmarks to identify the dorsal and caudal struts in endoscopic septoplasty are the axilla of the middle turbinate and pyriform aperture bone, respectively. The utilization of the inferior turbinate axilla as a caudal strut landmark showed larger variability and would potentially leave excessive caudal cartilage that could be manipulated if deviated.
