miraDry in THE Aesthetic Guide

In het juli/augustus nummer van THE Aesthetic Guide was uitgebreide aandacht voor miraDry en de miraWave technologie. Een aantal quotes van dermatoloog Christine Dierickx die gepubliceerd zijn in dit magazine:

"Selectivity is a key contributor to the success of any medical treatment, and Miramar’s miraWave therapy is no exception. In hindsight it seems obvious to use microwave energy in this way. Microwave energy agitates water molecules, which creates heat. It will be more specific to water, and sweat glands contain more water than neighboring structures in the skin, so this modality will selectively heat sweat glands."

"The addition of HVA provides another measure of safety as well. By using a tumescent method we inflate the area with a relatively large volume of solution, thereby creating a barrier between the skin we wish to treat aggressively and the sensitive underlying tissue, especially the lymph nodes and nerves that innervate the arm to provide sensation and motor function. This gives me added confidence that the chance of potentially injuring underlying tissue structures is minimized, thereby avoiding a temporary alteration of sensation, strength and motor function in the arm and hand. Up to now, using this protocol, every one of my patients has been satisfied with the procedure and the results.”

“Studies have shown that with laser hair removal, in a single treatment we may see 15% to 20% reduction. And as hair diameter and color is reduced over the course of several applications it becomes more difficult to treat. It is because of these and other factors that a patient may need up to ten sessions to achieve long-term hair reduction. Microwave-based hair removal has been shown to provide up to 70% reduction with a single treatment, so apparently it can treat these follicles more thoroughly. In one or two ses- sions with microwave technology we achieve better results for any hair color or type than we can expect with laser- or light-based modalities in five to ten applications.”

"In a study first presented by Dr. Brauer at the 2015 annual conference of the American Society for Laser Medicine & Surgery in Kissimmee, Fla., patients were recruited specifically for hair removal, rather than sweat and odor reduction, to investigate the effects of treatment on the axillary hairs. In this study, typical treatment settings were applied: a single pass with energy levels between 3 and 4, using the original intradermal anesthesia protocol. They found that hair reduction seemed dependent on the energy level chosen, meaning that more energy meant increased hair reduction. I performed a second study using the HVA protocol at the highest energy setting. We also decided to do a double pass rather than a single pass because pictures from the first study showed that small linear areas were skipped when treating. Since it is difficult to place a pulse exactly next to the previous pulse and one may miss hair follicles, our second pass was made perpendicular to the first pass. To control any potential increase in incidence of side effects, a split axilla protocol was used in which one side was treated with a single pass, and the other with the double pass pattern. What we found was excellent clearance of hair with no difference in side effects. Patients reported no more pain, swelling or inconvenience with the double pass side and at nine months out we’ve seen no regrowth of hair in the double pass side. And we included patients with very fine, light hair, which would have been poor candidates for laser or light-based hair reduction.”

"I'm a believer in the potential of microwave technology for other uses in aesthetic medicine. What we have is another mode of delivering heat energy, which is the backbone of many successful therapies we rely on today. The company is examining ways in which we may harness the technology differently to treat other indications and body areas. By manipulating the cooling protocol, for example, we may be able to change the depth at which we deliver energy to target sebaceous glands and treat acne, or target the skin to induce neocollagenesis. This is in addition to finding new ways to treat sweat glands and hair follicles on other body regions.”
