Root of the Nose

Description

Seen in lateral profile, the blue overlay localizes the radix nasi (root of the nose) at the superior nasal bridge where the paired nasal bones meet the frontal bone at the frontonasal suture, just inferior to the glabella. Anteriorly, the bony bridge continues into the cartilaginous dorsum nasi, with the upper lateral cartilages lying caudal to the nasal bones and deep to the skin of the nasion region. Superior and posterior to the radix, the frontal bone forms the lower forehead; inferiorly, the bridge slopes toward the tip, while the orbit and medial canthus sit slightly posterior and superior relative to the highlighted band. For rhinoplasty planning, few surface landmarks matter more than the nasion, because small changes in radix height and position can alter the apparent nasal length, dorsal line, and nasofrontal angle when assessed in profile. This lateral view supports discussion of dorsal augmentation or reduction, osteotomies, and management of the keystone area where nasal bones, upper lateral cartilages, and the dorsal septum interlock, a common site for postoperative irregularity if support is compromised. Profile assessment is the standard. The ability to reference the radix precisely also matters in trauma, where nasal bone fractures and frontonasal junction tenderness can accompany septal hematoma and airway compromise. Use this render in head and neck anatomy teaching to anchor surface anatomy of the nasion and bridge, or in facial plastic surgery and otolaryngology materials illustrating preoperative analysis and anthropometric norms in a Black female subject. It also fits medical publishing layouts that need a clean lateral facial silhouette with a targeted overlay for patient education on dorsal bridge contouring and fracture location.
