The results of periorbital rejuvenation with botulinum toxin A using two different protocols

Lifting effect of onabotulinumtoxinA in patients treated for glabellar and crow's feet rhytids

OnabotulinumtoxinA injection can enhance the appearance of the eyes. This study evaluated the lifting effect of onabotulinumtoxinA treatment of the eye area. A retrospective, single-center audit of patients treated for glabellar and crow's feet rhytids was undertaken. Standardized photographs taken before and 2-4 weeks after treatment were assessed. Computer-based measurements were made of the height of the visible superior tarsal plate (STP) and brow (measured from upper eyelid lash edge to eyebrow base) at rest and maximum frown. One hundred patients were included (96 females; mean age: 46.2 ± 8.8 years). Mean onabotulinumtoxinA doses were 14.95 ± 0.61 units (glabella) and 17.83 ± 2.74 units (crow's feet). There were significant post-treatment increases in mean STP height at rest (left side, 0.76 ± 0.99 mm, p = .02; right side, 0.79 ± 0.94 mm, p = .01) and maximum frown (left, 2.25 ± 1.52 mm, p < .0001; right, 1.87 ± 1.34 mm, p < .0001), and mean brow height at rest (left side, 1.54 ± 1.49 mm, p = .0006; right side, 1.47 ± 1.84 mm, p = .0009) and maximum frown (left, 4.37 ± 2.29 mm, p < .0001; right, 4.16 ± 1.88 mm, p < .0001). OnabotulinumtoxinA injection is effective for elevating brow position and increasing STP show.

Botulinum Toxin for Eyebrow Shaping: A Systematic Review

BACKGROUND

Currently, there is no standardized approach for eyebrow shaping with botulinum toxin, and controversies still exist regarding this subject.

OBJECTIVE

The objective of this systematic review is to summarize and compare all the published data regarding eyebrow shaping with botulinum toxin.

METHODS

On March 10, 2017, an online search of published articles in the Medline, Embase, and Cochrane databases were conducted. All articles that used objective measurements to quantify the eyebrow changes after botulinum toxin injection were included in this review.

RESULTS

Eleven studies were selected for inclusion with a total of 585 patients. All the included studies used onabotulinumtoxin A. Seven studies injected both the lateral and the medial eyebrow depressors, 2 studies injected the lateral depressors alone, and 2 studies injected the medial depressors alone. The highest elevation was observed in the lateral brow (0.4-4.8 mm). Bruising and headache were the most frequently reported complications, and only 5 cases of eyelid ptosis were noted.

CONCLUSION

Botulinum toxin injection for eyebrow shaping is a noninvasive, safe, and reproducible procedure. Eyebrow reshaping can be achieved by targeting different muscle groups. However, further randomized controlled trials are warranted.

Effect of brow lifting using botulinum a toxin on upper eyelid height in patients with ptosis undergoing the frontal sling technique

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 previously undergone ptosis correction using the frontal sling.
