External Male Nose, Lateral View

Description

Presented in lateral profile, the external male nose is defined by the radix at the nasofrontal junction, the dorsum nasi sloping inferiorly to the tip (apex), and the columella separating the anterior nares. The alar lobule and alar rim outline the lateral margin of the nostril, while the soft triangle lies between the alar cartilage and the tip-defining points. Superiorly the nasal bones underlie the upper third of the dorsum, and inferiorly the greater alar cartilages shape the lower lateral contour, with the nasolabial angle formed between the columella and upper lip. This lateral view matters because rhinoplasty planning and trauma assessment depend on dorsal lines and on the transition from bony vault to cartilaginous vault at the rhinion, a frequent site of palpable irregularity and postreduction step-off after nasal fracture. Alar collapse and external nasal valve compromise often present as contour change at the alar rim and soft triangle, and you can correlate those surface landmarks with the underlying lower lateral cartilage during functional evaluation. Small asymmetries read clearly from the side. Use this illustration for head and neck gross anatomy teaching, facial plastics and ENT lecture slides on external nasal valve mechanics, and clinical atlas figures describing dorsal hump reduction, osteotomies, or posttraumatic deformity patterns in the nasal region.
