What are the longterm effects of cutting nerves? (photos)

I tell every forehead reduction patient that the scalp will be numb in the hair-bearing portions along the front for several months postoperatively. While long-term or permanent numbness is a risk, I've not had any patients complain about this beyond about 6 months after surgery.

Most patients will report some occasional itching, tingling, "electric" sensations, etc in the scalp while the nerves recover. That being said, most patients do not complain about the scalp numbness at all postop.

All the best,

Every patient is numb after a hairline lowering.  I am not sure if the Dr. below has ever performed a hairline lowering or spoken to the patient afterwards if he thinks that patients don't complain of numbness, but the average time for numbness is 6 months.  I have performed hundreds and hundreds of hairline lowering procedures and have never heard of a patient that was not numb after the procedure.  This is expected and not considered a complication.  I have never had a patient describe long term numbness but I suppose this is possible.  

Cutting nerves mean you will feel numbness.  Usually the numbness last for several weeks to months before you regain sensation.  In rare cases the numbness will be permanent.  This is a risk you need to discuss with your surgeon.
