Anatomical Location of the Dorsum of the Nose

Description

Seen in lateral profile, the highlighted dorsum nasi (nasal bridge) extends from the nasion at the frontonasal junction to the rhinion at the inferior margin of the nasal bones, where the bony vault transitions to the upper lateral cartilages. Superiorly it relates to the frontal bone and glabellar region, while inferiorly it slopes toward the tip-defining area over the lower lateral cartilages and columella. Anterior to the nasal cavity, the contour you see is governed by the thickness of the overlying skin and subcutaneous tissue as much as by the osseocartilaginous framework. The blue overlay isolates the surface anatomy of the bridge for clear regional localization. For rhinoplasty teaching, the lateral view of the nasal dorsum is the workhorse because it lets you judge dorsal height, the radix position, and the continuity of the brow tip aesthetic lines, and it maps directly onto where dorsal humps, saddle-nose deformity, or post-traumatic irregularities become obvious. Small changes at the rhinion can read as large contour changes on the surface, and this is also where osteocartilaginous instability can lead to step-offs after fracture reduction or dorsal reduction. A key landmark. The depiction on a Black female model supports discussions of nasal analysis that account for skin thickness and soft-tissue envelope behavior, which affects both surgical planning and expected definition. Use this artwork for head and neck anatomy courses covering external nasal landmarks, for facial plastic surgery lectures on dorsal hump reduction and dorsal preservation concepts, or for dermatology and ENT references that need a clean, labeled bridge region for documentation templates. It also fits patient-facing educational materials that explain where the nasal bridge sits relative to the bony vault and cartilaginous dorsum without drifting into procedural detail.
