Can thigh liposuction improve an “O-shaped” inner-thigh line?
Hello, this is Dr. Choi Pyongrim
from Lesarts Plastic Surgery.
When shaping an attractive thigh line,
the key is not simply the amount of fat,
but understanding the core structures
that define the overall leg silhouette.
Recently, many patients visiting for
inner-thigh liposuction express a concern:
“My upper inner thighs touch,
but the lower legs spread apart
in an O-shaped line.”
This pattern usually results from
prominence in the upper inner thigh
combined with fat imbalance below,
a structural issue difficult to fix
through exercise alone.
In such cases, thigh liposuction helps
refine unnecessary upper-inner bulging
and create a smoother lower contour,
making the entire leg appear straighter
and noticeably slimmer.
Once the inner-thigh line is corrected,
the excessive O-shaped gap softens,
and both inner and outer lines align
to create longer, more balanced legs.
So what causes this O-shaped contour
of the inner thighs in the first place?
1) Disproportionate fat accumulation
in the upper inner thigh
The inner thigh is an area
where the thickness of the fat layer
can easily differ between the upper and lower parts.
Especially when fat accumulates more on the upper side,
while the lower side has relatively less fat,
The upper thighs remain close together,
while the lower legs spread apart,
creating an O-shaped appearance.
This pattern is common in women
and is influenced by hormones
as well as inherent body structure.
Other contributing factors include:
2) Inner-thigh adductor tension
and muscular asymmetry
3) Skeletal alignment patterns
4) Gait habits and pelvic imbalance
5) Fat-layer thickness changes
from weight fluctuation
When dieting and rebound cycles repeat,
fat may persist selectively in certain areas,
a phenomenon known as residual fat imbalance.
The inner thigh often retains thicker fat
only in the upper segment,
which can accentuate an O-shaped contour.
Today, I will discuss how removing
excess fat from the upper inner thigh
can effectively improve the O-shaped
inner-thigh line.
[Patient Information]
Age: mid-30s
Height: 164.5 cm
Weight: 53.9 kg
BMI: 19.9
This patient has an overall lean frame,
but tends to accumulate fat in the lower body.
She wished to refine the overall thigh size
and achieve a more balanced,
harmonious thigh contour.
[Preoperative Assessment]
-Fat accumulation in the upper inner thigh
with prominence over the saddle-bag area
-Noticeable thickness difference between
the upper and lower one-third of the thigh
-Moderate development of the anterior thigh,
slight development of the adductors
and hamstrings
-Skin elasticity better than average
for her age
[Surgical Plan & Approach]
Full-thigh liposuction
-Reduce upper inner-thigh bulging
while minimizing suction
in the mid-to-lower inner thigh
-Release adhesions in the saddle-bag area
from previous suction
and redesign a natural contour
-Contour the anterior thigh
according to underlying muscle shape
-Minimize suction beneath the gluteal line
to prevent postoperative sagging
[Postoperative Progress]
Comparison of preoperative results
and three-month postoperative outcome
after thigh liposuction.
Lesarts Thigh Liposuction Before & After – Front View
From the front view, the upper inner-thigh size
has decreased, improving the O-shaped contour
that extended downward, creating a straight-line
appearance all the way to the knees.
The outer thigh line also shows improvement,
with reduced width at the upper saddle-bag area,
and a smooth, natural connection toward the lower leg.
Lesarts Thigh Liposuction Before & After – Back View
From the back view, removing fat in the
saddle-bag area creates a visually longer leg.
The gluteal line is preserved, while the
inner-thigh to inner-thigh line connects naturally.
The definition of the posterior thigh muscles
is minimized, creating a smooth contour.
Lesarts Thigh Liposuction Before & After – 45 Degree Side View
Lesarts Thigh Liposuction Before & After – 90 Degree Side View
The front and back thigh width has decreased,
connecting smoothly with the calf line.
Anterior thigh muscle definition is minimized,
and sagging below the gluteal line is reduced.
Overall size has reduced, particularly in the upper thigh.
This improved the O-shaped inner-thigh contour,
balancing the width between upper and lower segments,
and achieving proportional overall thigh harmony.
Liposuction to correct upper-lower imbalance
in the inner thigh is not just fat removal;
it is a body-contouring procedure
that reshapes the leg silhouette.
By delicately reducing upper-inner protrusion
and naturally connecting the lower line,
the “upper thighs touch, lower legs spread”
O-shaped leg concern can be effectively improved.
If you are concerned about your thigh lines,
a professional consultation can determine
the best contouring plan for your body.
This approach allows you to achieve
a more balanced silhouette and
confidence in your leg shape.
