In this study, brow lifting with botulinum A toxin was performed on patients whose ptosis was corrected using the frontal sling technique, and the effects of this application on ptosis were investigated. Seven patients ( with 12 eyelids) on whom the frontal sling procedure was performed using a tensor fascia lata graft were enrolled in the study. The patients underwent brow lifting using botulinum A toxin. Digital photographs of the patients were obtained before and 21 days after botulinum A injection. In digital imaging analysis, although a statistically significant elevation was detected in the eyelids and brows of the patients following botulinum A injection, it did not to lead to a significant difference in the degree of lagophthalmos. In the current study, this procedure was found to reduce the degree of ptosis without increasing the degree of lagophthalmos in patients who had previ-ously undergone ptosis correction using the frontal sling.
