Botulinum Toxin for Paramedian Interpolated Forehead Flaps.

The forehead skin closely resembles the texture and color of the midface region. As such, the use of a paramedian forehead flap to repair a midface defect provides optimal cosmesis; however, the donor forehead site may be left with an undesirable scar in a highly visible region of the face. Cutaneous surgeons possess a variety of traditional techniques intended to minimize scarring. We have found that the addition of 50 units of botulinum toxin at the time of wound closure has improved scar outcomes for patients undergoing reconstruction with paramedian interpolated flaps. Possible mechanisms for the efficacy of botulinum toxin lie in its ability to chemically paralyze the frontalis muscle and glabella complex. This immobilization leads to a reduction in unwanted wound tension during the most vulnerable first few days of healing.
