FRIDAY, March 9, 2018 (HealthDay News) — Botulinum toxin injections in surgical wound closure immediately after surgery improve facial surgery scars, according to a small study published in the March issue of Plastic and Reconstructive Surgery<\/i>.<\/p>\n
Li Hu, Ph.D., M.D., from the Shanghai Jiao Tong University, and colleagues injected botulinum toxin type A into half of each surgical wound closure among 16 consecutive patients who underwent facial surgery between June and October 2015. At six-months post-surgery, two plastic surgeons assessed the scars independently, using the visual analogue scale and the Vancouver Scar Scale.<\/p>\n
The researchers found that, based on the 14 patients who completed the study, the visual analogue scale score and scar width measurements showed a significant improvement in appearance and narrower scars for the halves of the scars treated with botulinum toxin type A (P = 0.046 and 0.001, respectively). The mean Vancouver Scar Scale score was 4.68 for the group injected with botulinum toxin type A versus 5.24 for the control group (P = 0.15).<\/p>\n
“This study demonstrates that early post-surgical botulinum toxin injections can produce better, narrower, and flatter facial surgical scars,” the authors write.<\/p>\n
