Male vs Female Nasal Size, Morphology & More

Male nasal bones tend to meet in the midline at a sharper angle and the nasal aperture is higher and narrower, with sharp rather than rounded margins.

Morphometric Study of Nasal Bone and Piriform Aperture in Human Dry Skull​

Shape and size analysis of the piriform aperture and nasal bone showed the existence of a significant sexual dimorphism. The mean width of the piriform aperture was 24.9±1.59 mm in males and 22.77±1.57 mm in females, the mean length was 29.57±3.28mm in females and 31.16±3.58mm in males.

CT evaluation of the bony nasal pyramid dimensions ​

The bone thickness was 2.23 mm ± 0.15 mm in males and 2.19 mm ± 0.14 mm in females at the level of upper border of the nasal bone; 1.82 mm ± 0.32 mm in males and 1.81 mm ± 0.25 mm in females at the intermediate level; and 1.73 mm ± 0.30 mm in males and 1.86 mm ± 0.69 mm in females at the lower border of the nasal bone. The mean thickness on the lateral osteotomy line was 1.85 mm ± 0.32 mm in males and 1.91 mm ± 0.46 mm in females. The mean thickness of the medial osteotomy line was 2.08 ± 0.17 mm in males and 2.04 mm ± 0.17 mm in females. The mean length of the nasal bone was 30.61 mm ± 1.26 mm in males and 29.01 mm ± 1.12 mm in females. The mean width of the pyriform aperture was 18.83 mm ± 2.17 mm in males and 18.19 mm ± 1.85 in females.

Nasal Skin Thickness Measurements Using Computed Tomography in an Adult Saudi Population​

When the nasal skin thicknesses were compared between men and women, a significant difference was observed only at the columella (P = 0.016).

Male versus female skin: What dermatologists and cosmeticians should know​

The studies show that the skin parameters of hydration, transepidermal water loss, sebum, microcirculation, pigmentation, and thickness are generally higher in men but skin pH is higher in women. Also, skin pigmentation and thickness are significantly higher, facial wrinkles are deeper, and facial sagging is more prominent in the lower eyelids of men.

The male nose, in general, tends to be
more protrusive, longer, wider, more fleshy, and tends to have larger and
more flaring nostrils. All of this is in contrast to a relatively thin and
less protrusive female nose.

The male nose is proportionately larger than the female
nose. Women tend to have smaller noses with more concave
dorsal morphology in profile view, whereas men’s noses are
relatively larger and more pronounced.

The male nose is generally larger than the female nose because of the increased volume of cartilage and bone. In contrast, female noses are smaller and shorter.

Ontogenetic scaling of the human nose in a longitudinal sample: implications for genus Homo facial evolution - PubMed​

We found that males and females exhibit similar nasal size values early in ontogeny and that sexual dimorphism in nasal size appears during adolescence. Moreover, when scaled to body size, males exhibit greater positive allometry in nasal size compared to females.

Sexually dimorphic differences in nasal development and scaling mirror patterns of ontogenetic variation in variables associated with oxygen consumption and tissue maintenance.

The ontogeny of nasal shape: An analysis of sexual dimorphism in a longitudinal sample - PubMed​

However, as sitting height increases males exhibit a disproportionate increase in nasal region height that is not present in the female sample. Moreover, the male nasal region is less integrated with the surrounding facial skeleton when compared to the female sample.

(PDF) 3D ANALYSIS OF SEXUAL DIMORPHISM IN THE NASAL CAVITY OF MODERN HUMANS​

We confirmed sexual dimorphism in this structure, males having larger
airways than females. The outflow region in the nasal cavities differs in
absolute and relative size, especially in the proportions of the choanae.
This could be related to respiratory oxygen consumption and body energy
expenditure.
Our findings support the
hypothesis that human upper airways are larger in males than in females,
as proposed in Rosas and Bastir (2002). Larger choanae in males permit
inhalation of greater air volume in the respiratory sistem than smaller
female choanae (Mlynski et al., 2001).

Are gender differences in external noses caused by differences in nasal septal growth? - PubMed​

Nasal septa and external noses were both larger in males than in females at the beginning of the study period, although not significantly. The differences became significant throughout the study due to differential increases between the sexes during the monitored growth spurts.

Adolescent growth patterns of the bony and cartilaginous framework of the nose: a cephalometric study - PubMed​

Nasal height and nasal bridge length became fully mature in males at 15 years and fully mature in females at 12 years. The upper nasal dorsum, lower nasal dorsum, anterior nasal depth, and posterior nasal depth exhibited continuous growth up to 14 years in males and 2 years earlier in females. Nasal tip protrusion approached its mature size in males at 15 years and at 13 years in females.
