Energy-Based Treatments Safe After PMMA Injections

Energy-Based Treatments Safe After PMMA Injections

In a recent study, researchers Douglas C. Wu, MD, et al, evaluated the safety and histopathological effects of different laser, light and ultrasound modalities on skin previously injected with a polymethylmethacrylate (PMMA) filler (Bellafill, Suneva Medical).

Bellafill is a soft tissue dermal filler composed of non-resorbable microspheres, suspended in a water-based carrier gel with 3.5% bovine collagen; it is FDA approved for the correction of nasolabial folds and atrophic facial acne scars.

Ultrasound Guidance More Accurate Than Clinical Markings in Masseter Injections

Ultrasound Guidance More Accurate Than Clinical Markings in Masseter Injections

Individual anatomical variations can make it difficult to safely and effectively treat bruxism with neuromodulators, leading researchers Natacha Quezada-Gaon, MD, et al, of Pontifical Catholic University’s Department of Dermatology in Santiago, Chile, to investigate the use of ultrasound-guided injections. Thirty patients with bruxism were treated with botulinum toxin injections in each masseter muscle. The authors used ultrasound imaging and clinical markings—which were later compared—to guide their injections in 20 patients and clinical markings only in 10 cases.

Ultrasound for Neck Laxity

Ultrasound for Neck Laxity

In a study published in the Journal of Drugs in Dermatology (May 2016), Leslie Baumann, MD, and Brian Zelickson, MD, investigated whether application of microfocused ultrasound with high-resolution ultrasound visualization (MFU-V) at two focal depths would produce clinical results superior to treatment at a single focal depth. They used the Ulthera device, which administers MFU-V to produce noninvasive lifting and tightening of lax skin on the face and neck.

Ultrasound May Reduce Sebum Production in Acne Patients

Ulthera for acne reduction

Girish “Gilly” Munavalli, MD, presented the results of a study on the use of focused ultrasound (MFU-V, Ultherapy, www.ulthera.com) for the treatment of moderate to severe acne as a poster at the 2013 American Academy of Dermatology conference in Miami. The study followed 10 subjects with moderate to severe acne, defined as at least 20 lesions each of inflammatory papulopustular and comedonal acne. Each subject received three treatments spaced 14 days apart. Energy was delivered at 1.5mm/10MHz and 1.0mm/10MHz. Dr.
