Anatomical Location of the Ala of the Nose

Description

Captured in lateral profile, the external nose is defined by the ala nasi (nasal wing) forming the lateral boundary of the naris, with the columella and the anterior margin of the nasal septum positioned more medially. Superior to the ala, the nasal dorsum and tip outline the anterior contour of the nasal pyramid, while the alar-facial (alar) crease marks the junction between the mobile alar lobule and the adjacent cheek. A blue overlay isolates the nasal region, directing attention to the soft-tissue envelope and the alar rim from the tip toward the alar base. For rhinoplasty planning, few landmarks matter more than the alar rim and alar base when viewed in profile, because small changes in support or scar contracture can translate into alar retraction, nostril show, or external nasal valve compromise. This view also supports teaching of ethnic nasal anatomy, where differences in skin-soft tissue thickness, alar cartilage shape, and alar base width influence technique selection, including alar base reduction (Weir excisions) and tip support strategies. Subtle asymmetry becomes obvious here. Use this asset in otolaryngology and facial plastic surgery lectures, preoperative counseling materials discussing alar base modification, or dermatology and primary care references that need clear identification of the ala versus septum when describing lesions near the nostril margin. It also fits anatomy and surface landmarks coursework focused on the external nose and nasal airflow mechanics. Anatomical accuracy verified by SciePro's Medical Advisory Board.
