Klingon Forehead

Abnormal horizontal wrinkle lines that appear above the lateral aspect or tail of the eyebrows on the forehead. These lines tend to heap and can extend from the eyebrow itself all the way to the hairline. They are the result of abnormal muscle recruitment following aggressive BOTOX®; treatment to the forehead. In these cases, the BOTOX® has been placed in the glabella and central forehead. This paralyzes the central portion of the forhead creating central descent of the forehead and eyebrows. The brain automatically compensates for this by activating the forehead elevators. Unfortunately, the only muscle in the forehead not affected by the BOTOX® is at the sides of the central forehead. These muscles are forced to work extra hard to compensate for the fall in the eyebrow. The result is the heaping lines on the side of the central forehead referred to as a “Klingon” forehead.
