Starting on post-operative week three, the patient will receive 0.05mL aliquots of each injection (0.9%NS and 5-FU) sub-dermally into the brow incision spread out evenly over the brow, totaling 0.3-0.6 mL of each injection over each respective brow. Photos of the patient's brows will be taken, and then both the physician and patient will fill out a survey recording their impressions, the contents of which are listed in subsequent sections of this protocol. This same procedure will be repeated every three weeks for a total of up to four rounds of injections, thus the final round of injections will be given on post-operative week twelve. At each of these post-operative visits, incidence of any side effects is recorded, and if an unacceptably high rate of side effects occurs, the study will be precociously terminated.
