Background: In patients with large ventral hernias, botulinum toxin to external and internal oblique muscles decreases thickness and increases length. We examined the impact of botulinum toxin in the amount of loss of domain according to two ratios and in hernia size.
Methods: Between October 2021 and November 2023, 20 patients with ventral hernias measuring 10 cm or more on the horizontal size underwent the administration of 50 units of botulinum toxin to each external and each internal oblique muscle 4 weeks before their surgery.
