Skin Scarring Clinical Trial
Official title:
Use of Botulinum Toxin A in Direct Eyebrow Lift Scar: a Randomized Controlled Clinical Trial
Prospective, controlled and randomized study in which participants indicated for surgery to direct eyebrow lift will be randomized into two groups. In addition to surgery, the patients will be treated with botulinum toxin in one eyebrow and saline (placebo) in the other site. The patients participate as treatment and placebo at the same time. Assessments will be carried out through non-invasive exams.
A component of eyebrow ptosis, part of the natural aging process, with or without asymmetries, is found in the majority of patients who seek the blepharoplasty procedure. There are several procedures to address this condition, but none of them is undoubtedly superior to the others. The direct eyebrow lift technique is known for providing good eyebrow suspension, predictable results and relatively low complexity surgery, which can be performed with local anesthesia. However, the biggest concern for surgeons and patients is the final appearance of the scar, which will be in a visible area of the face. Botulinum toxin A has been used in recent studies precisely to improve the appearance of scars. Previous studies mainly evaluated traumatic lacerations and post-tumor excision reconstructions, obtaining positive results, with an improvement in the appearance of the wounds in patients who used the medication. It is a safe drug, used for several years for other purposes and without serious adverse effects according to these studies. The objective of this study is to compare the use of botulinum toxin A versus 0.9% saline solution in the healing of direct eyebrow lift surgery. ;
