Background Color

Breast Landmarks
Black arrow: sternal notch
Blue arrow: midclavicular line
Purple arrow: take off of breast
from chest wall (better seen
with lateral view)
Green arrow: infra-mammary
fold at meridian.
Orange arrow: midline of chest
wall.
Breast Landmarks
For each side, I measure:
SN - N: sternal notch to nipple
MC - TO: midclavicular line to
take off
TO - N: “take off” to nipple
M - N: midline to nipple
IMF - N: infra-mammary fold
at meridian to nipple
L – N: lateral to nipple (better
seen in a lateral or an oblique
view)
Normal Measurements
Yellow arrow: lateral most landmark
of breast
Glandular-ptosis &
Asymmetry
Note:
1.
White lines indicate
asymmetry of breast
contours. Lower
contours are almost
“boxy” in shape
2.
Blue lines show
exaggerated
anterior axillary
contours.
Glandular-ptosis &
Asymmetry
Note:
1.
Yellow line indicates level of
IMF.
1.
A major part of the breast,,
is below the yellow line.
2.
Nipple is above the line
2.
Blue line indicates lateral most
extent of her breast.
3.
White arrow indicates the take
off of the breast from the chest
wall.
Glandular-ptosis &
Asymmetry
Preop right
lateral
Grade 2 Ptosis
Note:
1.
2.
Good overall symmetry
1.
Nipples equidistant
and almost level
2.
Lower contour of
breast symmetrical
3.
Outer upper curves
of breast slightly
exaggerated
She still needs a
mastopexy (breast lift)
Grade 2 Ptosis
Preop right lateral
Note: can’t see lateral
most border of breast.
Nipple below IMF (yellow
line) but above most
dependent part of breast.
Grade 3 Ptosis
Note:
1.
Nipple is virtually the lowest
point of the breast relative to
the IMF (red line)
2.
Level of TO (red arrow) gets
farther away from the MC
(yellow arrow) as breast sizes
get into the very large range
