Nose anatomy and its effects on aesthetics and facial harmony/dimorphism (1 Viewer)

[idkwhatodo]

Introducion
The visible nose is a mix of bone (upper third) and cartilage (lower two-thirds), covered by skin/soft tissue:
Nasal bones-form the upper bridge

Spoiler: the nasal bones are two small bones forming the upper third of the nose it also articulates with the frontal bone (forehead) and maxilla. Functionally it provides rigid support as anchor point for the rest of the nasal framework. It determines bridge width and height Influences Straight vs dorsal hump (often bone + cartilage combo) [ATTACH type="full" width="257px

Septal cartilage: central support “strut”

Spoiler: Structure Flat cartilage devides the nasal cavity into left/right Extends from deep inside toward the tip .Functionally its THE main structural pillar it controls Tip projection, dorsal, alignment, overall stability thats why Surgeons preserve the “L-strut” an L-shaped portion for support. it impacts the the straightnes of the nose from the frontal profile a good septum can create a symmetricial straight nose a bad one that deviates from the norm creates assymetry and underprojection in the tip of the nose [ATTACH type="full

Upper lateral cartilages: shape the mid-vault (the middle third)

Spoiler: Structurally its a pair of cartilages attached to septum Sit between nasal bones (above) and lower cartilages (below) Functionally is maintains mid-vault width forms part of the internal nasal valve (critical for breathing) Aesthetic impact: it defines dorsal aesthetic lines (those smooth lines from brow to the tip) This area is where many bad rhinoplasties fail [ATTACH type="full" width="207px

Lower lateral (alar) cartilages: define the tip, nostrils, and rim

Spoiler: Structurally its an u-shaped paired cartilages forming: Tip (domes) Nostril rims Divided into: Medial crura (center) Lateral crura (sides) Functionally it controls: Tip shape Tip rotation Nostril structure Aesthetic impact Bulbous tip creates wide/weak cartilage or thick skin Sharp tip creates strong, defined domes which determines if ur nose tipe is upturned or droopy Narrow or wide tip all Key concepts of “The Tripod theory” [ATTACH type="full" width="235px

Columella: the strip between the nostrils

Alar base: the outer width of the nostrils

Spoiler: Structurally its the outer edges of nostrils (alar wings) Includes soft tissue + lateral crura support Functionally Controls Nostril width Airflow entry etc[ATTACH type="full

These structures don’t just act independently they conect just having one good section is not enough
Nasal bones and upper lateral cartilages define the bridge lines
Septum and lower lateral cartilages control projection and tip
Alar base and tip determine front-view width
proportions & angles
Nasofrontal angle

Spoiler: ]~115–130° typical aesthetic range[/SPOILER] [B]Nasolabial angle[/B] [SPOILER=

-Women: ~95–110°
-Men: ~90–95° (slightly more downward)

other ratios imapcted by the nose are:
middle third

Spoiler: ]ideal 32-33.5%[/SPOILER] [B]ipselateral alar angle [/B] [SPOILER=

ideal:85-90*

chin to pilthrum

Spoiler: ] ideal:2.2 - 2.8.for men 2.1-2.4 for women[/SPOILER] [B]Lower third proportion[/B] [SPOILER=

ideal:30.6-34%

effects on dimorphism
a broader nose are viewed as a dimorphic trait for men while a smaller nose is viewed as a dimorphic trait for women
functionality diffrences
in this study

Spoiler: /

https://pmc.ncbi.nlm.nih.gov/articles/PMC10040417

Women had higher nasal resistance (NR)
(basically how hard it is for air to pass through)

Men had larger noses (surface area + volume)​

SA (surface area) = internal lining area
Volume = total space inside the nasal cavity

But SA:V ratio was the same​

Even though male noses are bigger, the proportion of surface area to volume is similar​

Men had higher SAHF50​

This is more technical, but basically:
-It relates to how airflow and heat exchange behave under stronger breathing conditions

Spoiler: short summarry made by chatgpt for retards

Female noses:​

• Smaller
• Higher resistance
• Better at conditioning air (warming/humidifying)

Male noses:​

• Larger
• Lower resistance
• Better at handling volume/airflow

Conclusion
if u have a shit nose get a rhinoplasty or clumela lowering or wtv u need see ya later

yes just fixed the spoilers i fucked them up

yes just fixed the spoilers i fucked them up

i heard FoidSlayer was good at this

i heard FoidSlayer was good at this

no ik how to do them but i somehow fucked emm up a bit and the 5 mins just expired so sum info was lost thanks for the help tho
