I can understand why you’re concerned, especially since it has been several years since the surgery and the area still feels and looks abnormal to you. What you’re describing — a visible dent, a sensation that there is still a “ball” there, and difficulty lifting the eyebrow on that side — is something that deserves a careful explanation. Based on your photo, the contour change looks more consistent with a localized depression or tethered scar than with a recurrent lipoma, although I can’t make a definitive diagnosis from an image alone. Why a Dent Can Happen After Lipoma Removal When a forehead lipoma is removed, the surgeon often has to create a pocket under the skin to remove the fatty mass. If the lipoma was relatively deep, healing can leave: Loss of volume where the lipoma was removed Scar tissue attaching the skin down to the deeper tissues Mild muscle or fascial disruption in the forehead This can create a shadow or indentation that sometimes looks like a lump next to it, even though the problem is actually a depression rather than a new growth. The Eyebrow Weakness Is the Most Important Clue You mentioned that you cannot lift the eyebrow normally on that side and that the skin of the eyebrow feels different. That makes me think about the frontal branch of the facial nerve, which helps elevate the eyebrow. A few possibilities: Temporary nerve irritation from the original surgery Scar tissue restricting movement of the frontalis muscle Partial injury to a small nerve branch during the procedure Less commonly, a persistent weakness that was never fully recognized A recurrent lipoma would not usually cause difficulty lifting the eyebrow. How to Tell the Difference A residual or recurrent lipoma is usually: Soft and mobile Feels like a rubbery lump under the skin Often becomes more noticeable when you press around it A scar-related depression is more likely to: Feel firm or tethered Have a fixed indentation Create an appearance that changes with lighting or facial expression Be associated with tightness or restricted movement What I Would Consider Next Because this has been present since 2022, the most useful next step would be imaging rather than guessing. High-Resolution Ultrasound This is often the best first test because it can quickly show whether there is: Residual lipoma tissue Scar tissue A fluid collection A true soft-tissue defect If the ultrasound is negative but the brow weakness is significant, an MRI of the forehead may provide more information about the deeper tissues and muscle. If It Is a Depression Treatment depends on the cause: Scar Tethering Subcision (releasing the scar attachment) Sometimes combined with filler or fat grafting Volume Loss Hyaluronic acid filler can work surprisingly well for small forehead depressions Autologous fat transfer is often preferred for larger or longer-standing defects because it restores living tissue rather than temporary volume One Important Observation From Your Photo The contour change appears subtle and localized rather than a prominent rounded mass protruding outward. That pattern tends to favor post-surgical contour irregularity over a persistent lipoma. I also notice that the eyebrow position looks slightly asymmetric, which supports your observation that the muscle movement may not be completely normal. My Honest Impression If I were evaluating this based on your history and photo, I would be more suspicious of a post-surgical depression with scar tethering and possible mild frontalis dysfunction than of a recurrent lipoma. The fact that you cannot lift the eyebrow normally is the feature I would take most seriously, and I would want that investigated rather than simply being reassured that it is “just a dent.” The good news is that both scar-related depressions and localized volume loss can often be improved, especially once imaging confirms exactly what is happening beneath the skin. The key is determining whether the contour problem is caused by missing volume, tethered scar tissue, or altered muscle function, because each of those is treated differently.
