Male Nose Dorsum

Description

Arising from the frontonasal junction, the dorsum nasi forms the midline ridge between the paired nasofacial grooves, extending inferiorly from the radix toward the supratip and nasal tip. Superiorly, the bony vault is implied by the paired nasal bones and the frontal processes of the maxilla, while the middle third transitions to the cartilaginous vault formed by the upper lateral cartilages. More inferiorly the contour continues over the lower lateral (alar) cartilages, with the columella and alar margin defining the anterior nasal aperture in profile. Surgeons and injectors judge nasal alignment and hump morphology from the dorsal profile because it reflects the relationship between bone, upper lateral cartilage, and septal support. Small changes at the osteocartilaginous junction, the typical site of a dorsal hump, can read as a disproportionate bridge or an open roof deformity after rhinoplasty if dorsal lines are not reconstituted. Clinical examination also ties dorsal contour to trauma patterns, including nasal bone fracture with dorsal deviation and associated septal hematoma risk. Use this asset for head and neck anatomy teaching, facial plastic surgery and ENT training materials, or as a reference figure in patient education on rhinoplasty planning and postoperative expectations. It also fits well in dermatology and aesthetic medicine content covering nasal bridge fillers and complications related to intravascular injection near the angular and dorsal nasal arteries.
