Participating in this research involves study participants being randomly placed in one of two treatment groups. The first treatment group will have \"Botox\" injected at the site of the planned forehead incision once the study participant is in the operating room and asleep, but prior to the start of the operation. The second treatment group will have normal saline injected at the site of the planned forehead incision to act as a control group. The study participant will then undergo paramedian forehead flap reconstruction of the nasal defect in the standard fashion by a facial plastic and reconstructive surgeon. At all post-operative appointments, photographs will be taken of the study participant's forehead scar, and the study participant will be asked to complete two short surveys. These two surveys will take approximately 5 minutes total to complete. Study participants may choose to participate in this research study so that the investigators may learn more about the cosmetic benefit of \"Botox\" when it comes to scar prevention which could potentially help future patients having the same surgery.",[26,27,28,29],"Skin Cancer Excision Site","Basal Cell Carcinoma","Squamous Cell Carcinoma","Melanoma",[31,32,33,34],"Mohs Micrographic Surgery","Nasal Defect","Paramedian Forehead Flap","Wound Healing","NOT_YET_RECRUITING","2026-07-16",{"date":38,"type":39},"2026-07-22","ACTUAL",{"date":41,"type":20},"2026-07-01",{"date":43,"type":20},"2029-06-30",{"name":45,"class":46},"Vanderbilt University Medical Center","OTHER"]
