Eyelid hollowing refers to a sunken appearance of the upper eyelid.
It is commonly associated with aging, but the mechanism behind it is not always the same.
In some patients, hollowing develops as orbital fat volume gradually decreases with age.
In others, the eyelid appears hollow not because fat is missing, but because the eyelid is being overstretched.
When ptosis is present, patients often lift the eyebrows to open their eyes.
As the forehead compensates, the upper eyelid skin unfolds like an accordion.
Over time, this repeated stretching can make the eyelid look hollow, even when volume has not truly been lost.
Another common cause is prior surgery.
If orbital fat was removed during previous eyelid procedures, true volume deficiency may be present.
These causes may look similar on the surface, but they are fundamentally different problems.
Treating all eyelid hollowing as a simple volume loss leads to incorrect decisions.
For this reason, injecting filler or performing free fat grafting is not always an appropriate choice.
Fat grafting involves harvesting fat from areas such as the abdomen or thigh and transferring it to the eyelid.
In this process, the transplanted fat is completely disconnected from its original blood supply.
As a result, survival is unpredictable.
Irregular contour, lumpiness, partial resorption, and inflammatory reactions can occur.
In some cases, the grafted fat must later be surgically removed.
Because of these limitations, adding volume alone does not reliably solve the problem—and can introduce new ones.
When volume restoration is necessary, our priority is to use the patient’s own orbital fat whenever possible.
Orbital fat repositioning allows volume to be restored while maintaining its native blood supply.
Instead of adding foreign or transplanted tissue, existing orbital fat is carefully mobilized and secured into the hollowed area.
This approach respects eyelid anatomy and reduces the risks associated with non-vascularized grafts.
Eyelid hollowing cannot be treated correctly without understanding why it occurred.
The decision is not about filling what looks empty, but about identifying what has actually changed.
