Procedure/cost to fix small hole caused by spacer? I want it to be smaller so that it's the same size as the other lobe.

Costs vary by surgeon. This repair is a minor surgical procedure performed under local anesthesia. Use Plato's Scar Serum afterwards to improve scarring. Best, Dr. KaramanoukianLos Angeles

Thanks for asking.  You hole is small enough to excise around the hole and close rather than cutting out a complete wedge.  This can be performed under local anesthesia and re-pierced 6 weeks later. 

Thank you for the question. 
The repair of the stretched ear lobe is a great procedure that can restore the ear lobe to a “normal” appearance". Care must be taken during this procedure to avoid reducing the size of the ear and/or creating a notch/ depressed appearance in the area of the rim of the ear lobe. It is usually done under local anesthesia with very high patient satisfaction rates. Re piercing can be done, preferably in a spot away from the scar line, a few months down the line. Costs vary from practice to practice ($800-$1000 in our practice).
I hope this helps.
