Major Alar Cartilage as, Anterior View

Description

Centered on the external nose in anterior orientation, the major alar cartilage (greater alar cartilage) forms the soft-tissue framework of the nasal tip and ala, with the medial crura positioned adjacent to the caudal nasal septum and the columella in the midline. Laterally, the lateral crura sweep inferolaterally toward the alar margin, defining the contour of the nostril rim and the nasal apex. Surrounding bony landmarks of the viscerocranium are apparent, including the piriform aperture of the maxilla and the nasal bones superiorly, with the nasal septum and internal nasal cavity highlighted to orient midline relationships. Clear spatial context. Anterior visualization of the medial and lateral crura matters because it clarifies how small variations in cartilage shape translate into tip projection, alar flare, and external nasal valve competence. This is the working anatomy for open rhinoplasty, where cephalic trim, dome sutures, or alar batten grafts are planned relative to the lateral crus to avoid postoperative alar rim retraction and inspiratory collapse. It also supports teaching on septal deviation and columellar alignment, since the medial crura and caudal septum interact directly at the base of the nose. Common use cases include otolaryngology and facial plastic surgery teaching files, operative consent diagrams, and textbook figures explaining nasal tip support mechanisms and external nasal valve anatomy. It also fits head and neck anatomy curricula that connect facial skeletal landmarks to overlying cartilage in the male adult nose. Anatomical accuracy verified by SciePro's Medical Advisory Board.
