Ala of the Male Nose, External Anatomy

Description

Along the inferolateral margin of the male external nose, the ala nasi forms the rounded wing that curves around the naris (external nares) and meets the nasal tip anteriorly. Medially, the alar rim borders the nasal vestibule and frames the nostril aperture, while superiorly it blends into the lateral wall of the nose toward the alar groove and sidewall. The soft tissue contour implies the underlying greater alar cartilage (alar cartilage) with its medial and lateral crura shaping the rim and the dome region, even when the cartilage itself is not exposed. Skin thickness and the fibrofatty tissue of the ala create a distinct convexity lateral to the columella. Clear visualization of the alar margin matters when you are planning or teaching nasal reconstruction and aesthetic rhinoplasty, where millimeters decide airway function and symmetry. Alar retraction, alar collapse, and external nasal valve compromise often present at the alar rim and are accentuated by scarring after trauma, skin cancer excision, or prior surgery. This is also where the alar base is assessed for reduction techniques and where clinicians look for asymmetry, notching, and vestibular stenosis. Use this asset in head and neck anatomy teaching, facial plastic surgery lectures, dermatologic surgery references for alar defects, and patient-facing education on nasal form and external nasal valve problems. It also fits well in ENT or plastic surgery atlases that need clean nomenclature for the ala nasi and adjacent surface landmarks. Anatomical accuracy verified by SciePro's Medical Advisory Board.
