Nose Flashcards
A dominant feature of the face, because of this, accurate size and form will be more important than on any other feature.
The nose
A pyrimidal mass.
Nose
The nose leans _________ to one side.
Asymmetrical
Form of the bilateral silhouette of the base of the nose:
Three Fused Spheres
The base of the nose is bisected by the upper lip.
Profile View of The Nose
- Leptorrhine
- Mesorrhine
- Platyrrhine
Racial Classifications of The Nose
- A nose of the white (caucasoid) race.
- Prominent at the bridge.
- Long
Leptorrhine (Western European)
- Nose of the yellow (mongoloid) race.
- Intermediate between the other two noses.
Mesorrhine (Asiatic)
- Nose of the black (African) race.
- Minimum projection at the bridge.
- Broad and short.
Platyrrhine (African)
- Size of the nasal bones.
- Margins of the nasal cavity.
Dimensions of the nose are indicated by these things.
- Width of the nose at the wings.
- Most inferior part of the nose at the nasal spine of the maxilla.
Margins of The Nasal Cavity
- Straight (Greek)
- Convex (Roman)
- Concave (Infantine, Retrosse, Snub, Pug)
Profile Classifications
- Most common type.
- The anterior ridge exhibits a straight line from the root to tip.
Straight (Greek)
- Sometimes called a hook or aquiline nose.
- The convexity may be continuous from the root to the tip.
Convex (Roman)
- Is the depressed type.
- The entire profile, from the root to the tip may dip concavely.
Concave (Infantine, Retrousse, Snub, Pug)
- Nasal Bones (2)
- Boarders of the nasal cavity.
- Nasal spine of the maxilla.
- Major Cartilages of the nose (5)
Anatomy of The Nose
- Bridge of the nose
- The thin covering of tissues repeat the form of the nasal bones.
Nasal Bones (2)
- Is pear shaped in form.
- Influences the length and width of the nose.
Boarders of The Nasal Cavity
- The sharp boney projection located medially at the inferior margin of the nasal cavity.
- It creates the boney limit of the length of the nose.
- It is covered by the columna nasi.
Nasal Spine of The Maxilla
- Septum (1)
- Superior Lateral Cartilage (2)
- Inferior Lateral Cartilage (2)
Major Cartilages of The Nose
- Large vertical cartilage.
- Divides the nasal cavity into a right and left chamber.
- Supplies almost all the projection of the inferior half of the nose.
- Bends to one side resulting in the nose being asymmetrical.
Septum (1)
These four cartilages support the covering tissues of the lower half of the nose.
Lateral Cartilages (superior and inferior)
- Connected to a nasal bone and an inferior lateral cartilage.
- Supplies the fullness to the lateral wall of the nose.
Superior Lateral Cartilage (2)
- Both cartilages unite at the medial line.
- Create the rounding form of the protruding lobe of the nose.
Inferior Lateral Cartilage (2)
