Preventing Complications of Lower Eyelid Fat Repositioning? The Key Is Surgical Planning Down to 1 mm

Preventing Complications of Lower Eyelid Fat Repositioning?

✨The Key Is Surgical Planning Down to 1 mm✨

Complications of lower eyelid fat repositioning can be more varied than expected.

The most important thing is not how to respond after a complication occurs,

but preventing it from happening in the first place.

The key to this prevention lies in “surgical planning in 1 mm increments.”

In other words, rather than relying solely on intuition or experience,

precise surgery based on anatomy is necessary.

The area beneath the eyes contains various structures in close proximity,

including fat, muscles, ligaments, nerves, and tear ducts.

That is why even a difference of just 1 mm

can lead to a completely different surgical result.

📢 The Importance of Anatomy-Based “Distance Planning” Beneath the Eyes

The arcus marginalis refers to the boundary line where the orbital septum

is firmly attached to the edge of the bone beneath the eye.

The arcus marginalis is considered one of the most important reference points

in lower eyelid fat repositioning surgery.

If this area is not dissected accurately,

it becomes difficult to move and secure the lower eyelid fat

stably beneath the bone.

As a result, the fat may push forward again after surgery

or become uneven.

Conversely, accurately identifying and carefully handling the arcus marginalis

can help maintain a more natural-looking lower eyelid area in a stable manner.

The distance from the eyelid margin with the eyelashes to the incision line

is also an element that must be considered.

The generally recognized safe guideline

is to maintain a gap of approximately 5.5 mm to 6.5 mm.

If this distance is not adequately maintained, the nerves of the orbicularis oculi muscle,

which play an important role in forming the lower eyelid fullness,

may be damaged.

This can disrupt the natural curve of the eyelid

or result in an unnatural appearance.

The medial canthal area is no exception.

The distance from the MCL (Medial Canthal Ligament),

that is, the medial canthal ligament, must also be considered.

It is advisable to begin the incision at a point

approximately 10–11 mm away from the ligament at the inner corner of the eye.

The reason for maintaining this safety distance

is to protect the tear duct and surrounding structures

needed for tear drainage.

The position and length of the incision also affect the result.

It is advisable to make the incision approximately 3–4 mm away from the outer corner of the eye.

Making the incision while maintaining this safety distance

can help prevent a visible scar while allowing for a faster recovery.

In addition, the width of the layer where tissue dissection and fixation are performed

should be kept consistently at approximately 3–4 mm.

If this balance is disrupted, the lower eyelid area may be pulled excessively,

or complications such as ectropion, in which the eyelid is pushed outward,

may occur, so caution is necessary.

📢 What Is the Key to Successful Lower Eyelid Surgery?

Ultimately, every step should be carried out using “measurements,” not “intuition.”

In other words, the more experienced the medical team,

the more likely they are to perform lower eyelid surgery

by strictly following anatomical standards and safety measurements

rather than relying on sensory judgment.

Of course, when various complications occur after surgery,

such as strabismus caused by injury to the inferior oblique muscle

or upward displacement of the lower eyelid,

being able to respond appropriately is also an essential skill for the medical team.

However, the most important thing is

not to create circumstances in which complications occur in the first place.

Ultimately, the key to successful lower eyelid fat repositioning surgery

is precise planning down to 1 mm

and maintaining that approach consistently throughout the entire procedure.
