I'm assuming that, with the total numbness description, that you had what's call a "coronal" brow lift with an incision starting above one ear and extending to the same location above the opposite ear. With this type of forehead lift, there is always numbness behind (posterior to) the incision line (not starting at the hairline - there should still be full sensation from the hairline to the actual incision line).However, most of this sensation will return over the course of the year following the surgery. Rarely does it come back completely -- all the way to the incision line -- but it usually returns to within a half inch or so, compared to the three inches you now experience.It is certainly possible to TRY repairing any nerve that has been cut, but it would be quite difficult to find the nerve endings as they are probably less than a tenth of a millimeter in diameter at this level of the scalp -- so it would take microsurgery techniques to accomplish this and the cost for doing so would be astronomical. Insurance would not cover this.The vast majority of people adjust to the loss of sensation very well. After all, sensation in this area isn't nearly as important as in other areas of your body. It can be quite annoying at first -- but my suggestion is to give it time. It is still pretty early out from the surgery, and you'll be surprised at how much sensation returns and how much you get used to the change in sensation. In the meantime, the main thing to be cautious of is using a hot curling iron or hair dryer, as you can be overheating or even burning the skin that is numb without realizing it.
