Nasal Region, Lateral View

Description

Seen in lateral profile, the external nose is defined by the nasion at the frontonasal junction, the nasal dorsum running inferiorly toward the tip, and the alar lobule forming the curved lateral margin of the naris. Superiorly, the paired nasal bones create the bony bridge, while the upper lateral cartilages and the greater alar cartilage shape the middle and lower thirds, with the columella projecting anteriorly between the nares. Inferior and posterior to the nasal base, the philtrum and upper lip provide soft-tissue reference points, and the nasolabial angle can be appreciated where the columella meets the upper lip. Profile matters. Lateral nasal anatomy is the working view for aesthetic and functional assessment before rhinoplasty, where dorsal hump reduction, tip rotation, and alar base management must respect the transition from rigid bony vault to pliable cartilaginous support to avoid postoperative saddle deformity or external valve collapse. Trauma evaluation also starts here: a seemingly minor deviation of the dorsum or step at the bony-cartilaginous junction often tracks with nasal fracture patterns and septal injury, even when intranasal findings are subtle. Surface contour is not just cosmetic, it is a proxy for structural integrity and airway risk. Use this profile illustration in head and neck anatomy teaching to anchor landmarks for palpation, surface anatomy exams, and safe injection planning around the dorsum and tip in facial aesthetics. It also fits surgical atlases and patient education materials that explain preoperative photographic analysis, standard views, and terminology used in rhinoplasty consult notes.
