Without a medical background like yours I can't see it. If I was her and looked like the before and then the after, I would be doing a happy dance, especially when she's in her 70's.The patient has a palsy of the frontal branch of the facial nerve which is why one eyebrow sits higher than the other. This may be a surgical complication. As the after is at 6 months, it appears permanent and may be due to injury of the facial nerve.
I had my eyebrows tattooed way back around 1990 - not like how they measure you now with a ruler. The tatts are still there. My eyebrows are uneven and one is higher than the other but I cover it up with eye shadow. When I get around to have my browlift I have to tell the doctor not to use my eyebrows as a gauge!
