Hyperdiluted Botulinum Toxin and Intense Pulsed Light Treatment: A Case Series to Illustrate a Novel Protocol for Hypertrophic Scar Reduction.

Hypertrophic scars can have significant and far-reaching effects on patients that range from itching to creating difficulty with mobility, all of which can negatively impact the individual's quality of life. A recent study showed that many patients with recent scars report pain, burning, pruritus, erythema, in combination with psychological difficulties that impact bodily movement, choice of clothing, and participation in leisure activities. Botulinum toxin Type A (BoNTA) and intense pulsed light (IPL) have shown promise in treating such scars. We propose a novel treatment protocol involving a 4-week intervention with hyperdiluted BoNTA injections and supplemental treatment with IPL for erythema, and a 6-month scar scale assessment and photographic documentation that occurs before and 6 months after treatment. We report four cases where using hyperdiluted BoNTA, either alone or in conjunction with IPL, substantially reduced scar size, improved overall scar appearance, and diminished erythema in areas on the face and the breasts. Although this report suggests that a schedule of alternating treatments with BoNTA and IPL may be beneficial in reducing scar size and enhancing appearance, further research is necessary to better understand the most effective dosages, the relationship between BoNTA and IPL, and the optimal management of scarring.

A Novel and More Aesthetic Injection Pattern for Malar Cheek Volume Restoration.

The loss of superior midface contour and projection can be corrected with the use of injectable hyaluronic acid (HA) dermal fillers, however, the most frequently used injection pattern employs a technique which was originally designed for malar implant surgery. Here we describe a novel injection pattern for restoring facial contours with a HA dermal filler inspired by traditional make-up artistry, which includes greater superolateral positioning of injection sites. Importantly, this technique helps injectors avoid creating an excess of volume in the anterior portion of the malar complex. Contributing authors/injectors, who now use this technique exclusively, have found that it has so far provided optimal aesthetic results for hundreds of patients with no observables complications. The malar cheek contributes much to the aesthetic curvature of the face and deserves a thoughtful update for injectable HA, as the traditional technique has never actually been aligned with its medium. In the experience of the contributing authors, this technique helps achieve a greater aesthetic outcome in the correction of midface contour deficiencies and has consistently resulted in high patient satisfaction.
