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)
- Dorsum
- Wings
- Columna Nasi
- Sides
- Nasal Sulcus
- Nasolabial Fold
- Anterior Nares
- Glabella
Parts of the nose
Anterior ridge of the nose.
Dorsum (Protruding Ridge)
- Root
- Bridge
- The protruding lobe
Components of the Dorsum
The concave dip below the glabella.
Root
The dome over the upper part of the nasal cavity formed by the nasal bones.
Bridge
The spherical area forming the inferior part of the dorsum.
- Tip
The Protruding Lobe
Point of greatest projection.
Tip of the Protruding Lobe
- Form the superior nasi.
- They form the inferior margin identified as the Aran of the wing.
- Creates the greatest width of the nose.
Wings (Lateral Lobes)
Superficial partition between the nostrils.
- The most inferior part of the nose.
- In a profile view, it is at a right angle to the upper lip.
Columna Nasi
The lateral walls of the nose between the wings and the bridge.
Sides
The small angular area between the wing and the cheek.
Nasal Sulcus
Anterior fold of the cheek.
Nasolabial Fold
The nostril openings.
Anterior Nares
The forehead eminence located above the root and the geometric shape is a triangle.
Glabella
