Bulge Under Left Eye After Blepharoplasty

Dear DDC38
The thing you are pointing to is well outside where the eyelid fat lives. And yet, in the photograph it appears to be in continuity with a ridge extending from the medial portion of the lower eyelid where the lower eyelid fat does live.
This is where a personal consultation is invaluable because in person we would know exactly what you are pointing to. However, assuming that what you are pointing to is the fullness outside of the orbital rim, this is a little relaxation in the cheek. It is not dramatic. When they are bigger, they are called festoons. I am going to go out on a limb and suggest without having seen your before pictures that this was actually present in the before images and is just a little more obvious to you because you have spent more time after surgery studying this area than you did before surgery.
If the issue was present before, then it is unlikely to resolve on its own with more healing. Generally this things are best treated by using a filler like Restylane to fill around the fullness. Cutting skin or lasering are excessive punishment for an issue like this.
If this was not present before surgery, then more healing is the answer. In this case, I would recommend that you wait a full year before thinking about doing something surgical about this issue.

Swelling, edema, after eyelid surgery is not uncommon. Each side can heal independently of one another; just like the right arm is different in strength to the left. If you sleep on this side it is more likely that the swelling will remain longer.
After eyelid surgery, we get swelling that gravity pulls down to this lower eyelid/ cheek junction. It should improve over time. Speak to your doctor about using gentle massage techniques and warm compresses to help hasten the swelling. If this does not alleviate the swelling your cosmetic surgeon may discuss other techniques.

It's not unusual for patients to experience swelling following blepharoplasfy surgery. In some cases, this swelling may persist for prolonged periods of time. When this situation arises, the swelling may involve the surrounding tissue because of gravity.In this particular case, the swelling appears to have extended beyond the original field of dissection of the transconjunctival blepharoplasty. It's asymmetric nature is probably positional in origin.Under these circumstances, it's appropriate to be patient. Patients should minimize salt intake and elevate the head whenever possible. When these steps are taken, this problem should gradually resolve.It's important that you maintain close contact with your plastic surgeon. Your surgeon should be able to get you through this difficult experience.
