Medical literature shows that nasal growth continues into late adolescence and early adulthood after skeletal growth subsides, but evidence covering the entire human lifespan is not present in these sources.
The results indicated that (1) increments in nose height, depth, and inclination are essentially complete in girls by 16 years of age, while continuing to increase in males up to and beyond 18 years; (2) the ratio of upper to lower nose heights remains at approximately 3:1 from 7 to 18 years in both sexes; (3) the ratio of nose depth to sagittal depth of the underlying skeleton changed from 1:2 at 7 years in both sexes to 1:1.5 in male subjects and 1:1.6 in female subjects at 18 years; (4) although upper nose inclination was similar for the two sexes, lower nose inclination was slightly larger in female subjects, especially after the age of 10 years; (5) persons with greater increments in nose depth than in nose height, or in nose depth than in the sagittal depth of the underlying skeleton, develop larger upper nose inclinations. The impact of nasal growth changes on orthodontic diagnosis and treatment planning was emphasized.

Development of the nose and soft tissue profile.
Cephalometric radiographs from a sample of 64 untreated persons (32 Class I and 32 Class II) were evaluated to determine the amount, direction and timing of facial soft tissue development. Twenty-five parameters were evaluated in the mixed dentition (7 to 9 years), the early permanent dentition (11 to 13 years), and early adulthood (16 to 18 years). Results showed that anteroposterior growth and subsequent increased anterior projection of the nose continued in both males and females after skeletal growth had subsided. However, females had concluded a large proportion of their soft tissue development by age 12 while in males continued growth was noted until age 17 resulting in their having greater soft tissue dimensions for many of the parameters evaluated. During the developmental period, the angular shapes and positional relationships of the nose, lips and chin remained relatively constant for both sexes and was relatively independent of the underlying hard tissues. Treatment planning implications may be drawn from the amounts and timing of the soft tissue development found in this study.
