Pearls from the ASDS meeting.
The annual American Society for Dermatologic Surgery conference in Chicago Oct. 15-18 was one of the best attended meeting in years. From injectables to lasers to reconstruction, the newest information was distributed among the members.
Here are pearls gained from the ASDS conference that every dermatologist should know:
There are reports of temporary alopecia of the beard area in men after deoxycholic acid (Kybella) injections in the submentum. Patients should be counseled prior to injection. Deeper injections in males, pinching up the skin, and penetrating the needle to the hub are measures that have been suggested to help minimize the risk of this potential side effect.
More than 60 cases of blindness secondary to filler injections have been reported, but such cases are likely underreported. The majority of reports were from South Korea and most cases were due to autologous fat transfer. High-risk areas include the glabella, nasal dorsum, and anteromedial cheek/tear trough due to retrograde flow of a filler embolus to the ophthalmic artery from anastomoses with the angular, dorsal nasal, and supratrochlear arteries. Cannulas are recommended as they are considered safer than needles, particularly when injecting either fat or fillers in the mid-face area.
However, even cannulas are not foolproof. There are some areas where periosteal placement of filler is important and therefore the use of needles is required, such as the anterosuperior temple, zygomaticomalar cheek, and central chin. Expert knowledge of the vascular anatomy of the face, including location and depth of important vessels, is a must.
If a vascular occlusion occurs --particularly to the ophthalmic artery that can result in blindness symptoms may include pain, visual disturbances, vomiting, and blanching/reticulation of blood vessels on the skin surface. Time is of the essence in preventing or reversing vision loss. If a hyaluronic acid filler was used, retrobulbar injection of at least 1,000 units of hyaluronidase and referral to an ophthalmologist should be done within minutes.
For body contouring and skin tightening, cryolipolysis and high-intensity focused ultrasound have shown results over the past several years. However, newer technologies including nonthermal focused ultrasound, multipolar radiofrequency, and fractional radiofrequency with microneedling, and a 1064 nm diode laser also show some promise.
The ablative fractional C[O.sub.2] laser was shown to be helpful for hypopigmented scars.
Malpractice lawsuits against cosmetic procedures are highest among physician extenders (physician assistants, nurses, assistants, etc.).
