What term refers to the soft tissue point at the end of the nasal septum?

The term that refers to the soft tissue point at the end of the nasal septum is "subnasale." This anatomical landmark is important in cephalometrics and orthodontics because it helps in assessing facial structures and relationships, particularly concerning the nasal region and the upper lip.

The subnasale is the point where the nasal tip meets the upper lip, making it a crucial reference for evaluating both soft tissue profile and facial aesthetics. Accurate identification of the subnasale can assist in treatment planning and orthodontic analysis, particularly in cases involving nasal morphology or changes due to dental or facial interventions.

In contrast, the pronasale is located at the tip of the nose itself, the labrale inferius refers to the midpoint of the lower lip, and the posterior nasal spine is a bony landmark located at the back of the nasal cavity. These points serve different functions in cephalometric analysis and do not denote the soft tissue structure at the end of the nasal septum, highlighting why subnasale is the appropriate choice.
