Lateral Examination of the Male Nose Dorsum

Description

Seen in lateral profile, the adult male dorsum nasi forms a continuous contour from the nasion at the root to the apex nasi, with the bridge (nasal bones superiorly and upper lateral cartilages inferiorly) creating the characteristic ridge. Superiorly, the dorsum blends into the glabella and frontal region, while inferiorly it transitions into the tip supported by the lower lateral (alar) cartilages. The columella lies anteroinferior to the tip as a soft tissue strut between the nares, and the alar rim defines the lateral boundary of the nostril aperture. Subtle surface landmarks, including the rhinion at the osseocartilaginous junction, are implied by the change in curvature along the nasal bridge. Profile assessment of the nasal dorsum drives both diagnosis and planning in rhinoplasty and facial trauma. A dorsal hump, saddle-nose deformity, and post-traumatic deviation often declare themselves most clearly in true lateral view because dorsal height, radix position, and tip projection can be judged against the facial plane without the confounding asymmetry seen in oblique angles. This is where the bony-cartilaginous transition matters. Osteotomies, dorsal reduction, and cartilage grafting strategies all start with this external topography. Use this lateral nasal bridge illustration for head and neck anatomy teaching (surface anatomy of the external nose), ENT and plastic surgery lectures on rhinoplasty analysis, and medical publishing content discussing dorsal aesthetic lines and osseocartilaginous landmarks in the male nose. It also fits clinical patient-education materials that explain why preoperative side-profile photographs are standard in nasal evaluation.
