What is an Occipital Knob?
Some people notice a hard bump at the back of their head, right where the skull curves downward. This is called an occipital knob. It’s a natural part of the bone, but in some people it sticks out more and becomes noticeable—especially in men with short or shaved hair.
While it’s not harmful, many patients seek treatment because the bump can affect appearance, make haircuts difficult, or cause self-consciousness.
Why Does It Happen?
The exact reason why the occipital knob is more prominent in certain people isn’t fully understood. For some, the scalp tissue over the bump can also become thicker, which makes the area stand out even more.
How is the Bump Reduced?
Occipital knob reduction is a simple outpatient procedure. Here’s how it works:
-
Anesthesia: You are comfortably asleep during the surgery.
-
Incision: A small, hidden incision is made in the scalp.
-
Bone reduction: The excess bone is carefully smoothed down.
-
Soft tissue adjustment (if needed): In some patients, the tissue around the bump is also thickened. If this is the case, some of this deeper tissue is reduced so the area looks smooth and natural.
-
No drains or scalp removal: The outer scalp is preserved, so healing is straightforward.
Most patients notice an immediate improvement once the bump is reduced. The head looks smoother and more natural, even the very next day after surgery.
The small incision needed to reduce the knob heals beautifully often leaving no visible scar.
Who May Need More Than Just Bone Reduction?
Before surgery, one clue can help determine whether only bone removal is needed or if tissue trimming should be added:
-
If the scalp moves easily over the bump ? usually bone reduction alone is enough.
-
If the scalp feels tight or stuck to the bump ? there may be extra tissue that should also be removed for the best result.
Key Takeaways
-
The occipital knob is a common bony bump at the back of the head.
-
In some people, extra tissue over the bump makes it look even larger.
-
Surgery can safely smooth both the bone and any thickened tissue to create a natural head shape.
-
Recovery is typically quick, and results are seen right away.
