This information was presented by Dr. Susan Weinkle at the 16th Annual ODAC Dermatology, Aesthetics and Surgical Conference held January 18th-21st, 2019 in Orlando, FL. The highlights from her lecture and live demonstrations were written and compiled by Dr Nikhil Shyam.

Dr. Susan Weinkle, an expert in the field of aesthetic and surgical dermatology, shares important anatomical concepts to consider when using neurotoxins and fillers safely.

The face can be split into 3 zones – the upper 1/3rd, the middle 1/3rd and the lower 1/3rd. Knowing the important vessels and nerves in each zone as well as their corresponding depth in the skin is crucial in order to minimize injury and utilize a safe technique when injecting neurotoxins and fillers.

Figure 1: D corresponds to areas where deeper injections are safer to avoid vasculature and nerves. S corresponds to areas where superficial (intradermal injections) are safer to avoid vasculature and nerves. Vessels shown are cartoon depictions of some of the more common arteries including the supraorbital, supratrochlear, superficial temporal, facial and superior and inferior labial arteries. Also depicted are the supraorbital, infraorbital and mental foramen that are located along the medial limbus.

Important Landmarks for the Upper 1/3rd of the Face

  • A line drawn vertically along the medial limbus denotes the anatomical locations of the supraorbital, infraorbital and mental foramen.
  • The supraorbital notch or foramen is the exit aperture for the supraorbital neurovascular bundle (NVB). While the vessels here initially lie deep in the skin, they become more superficial about 1.5 cm superior to the supraorbital foramen as they supply the forehead.
  • The supratrochlear NVB lies about 8-12 mm medial to the supraorbital NVB. The vessels are similarly deep initially and gradually become more superficial as they traverse superiorly to supply the forehead.
  • The supraorbital nerve, after exiting through its foramen, runs laterally and then superiorly about 1 cm medial to the temporal fusion line. It lies deep within the skin in this region.

When caring for individuals with sun-damaged skin, dermatologists need comfort with the full spectrum of photo-related skin disease. From assessment and treatment of actinic keratoses (AKs) and field cancerization, to long-term follow-up of cutaneous squamous cell carcinomas (SCCs), appropriate treatment and staging can improve patient quality of life and reduce health care costs, Vishal Patel, MD, said at the Orlando Dermatology Aesthetic and Clinical Conference.

“Actinic keratosis/squamous cell carcinoma in situ is not a disease; it’s a symptom of cutaneous carcinogenesis or field cancerization,” said Dr. Patel, director of cutaneous oncology at George Washington University Cancer Center, Washington. On the other hand, he added, “field disease can be a marker for invasive squamous cell carcinoma risk, and it requires field treatment.” Treatment that reduces field disease is primary prevention because it decreases the formation of invasive SCC, he noted.

Hyperhydrosis: Where Are We Now?

When you extend your hand to a new patient, and he reflexively wipes his palm before shaking hands, be alert. It’s possible you’re seeing primary hyperhidrosis, a condition that’s both more common and more disabling than once thought.

“Looking at the biology of sweating, normally, it’s a good thing – we need it to survive. However, hyperhidrosis is too much of a good thing – it’s an excess of what is needed for normal biology,” said Adam Friedman, MD, speaking at the Orlando Dermatology Aesthetic and Clinical Conference.

Recent data, he pointed out, show that hyperhidrosis is more prevalent than previously thought – about 4.8% of individuals may have the condition, with about half having axillary hyperhidrosis. Symptoms peak in early adulthood, with adults aged 18-54 most affected. “These are the prime working years,” he said.

About 2% of teens are affected, and many adults report that symptoms began before they were 12 years old. Hand hyperhidrosis is a factor for computer and electronic device work, sports, and even handling paper and pencils, noted Dr. Friedman, professor of dermatology at George Washington University, Washington.

“Does it affect quality of life? Yes. We have data to support the impact. The adverse impact is actually greater than that of eczema and psoriasis,” he said, adding that patients won’t always bring up their concerns about sweating. “Often, it’s the patient who apologizes for having sweaty palms or who sticks to the paper on the exam table. It’s worth asking these patients if they are bothered by excessive sweating.”

Vascular Compromise

Avoiding and treating vascular compromise with hyaluronic acid (HA) injections requires understanding the subtleties of underlying facial anatomy and keeping a well-stocked arsenal of treatments for impending necrosis, said an expert at the Orlando Dermatology Aesthetic and Clinical Conference (ODAC) in Miami.

“Some blood vessels may actually be in different locations than in some of the anatomic diagrams and cartoons that have long characterized their course,” said vice conference chair Joel L. Cohen, M.D., from Greenwood Village, Colorado, who serves on the teaching faculty for both the University of California, Irvine and the University of Colorado.

Although textbooks commonly depict the angular artery tracking adjacent to the nasofacial sulcus, he said, “it’s more common for the angular artery to be more lateral to that area, closer to the infraorbital distribution. In a recent cadaver study, only 19% of the time did the facial artery actually project upward along the side of the nose-cheek junction. But 32% of the time, the angular artery came off the facial artery earlier, and therefore coursed to more of the medial cheek area.”

The technique of aspirating before injecting is not foolproof. “There can be false negatives. A study indicates you probably have to pull back on the plunger for several seconds in order to physically be able to see if you’re in a vessel. We all surely realize that it is very difficult to have the needle in the exact spot you plan to inject, and then reposition your hand to pull back on the plunger of the syringe to try to aspirate, and then have your needle-tip remain in the exact same spot when you reposition again in order to inject. As you change your hand position to pull back on the plunger, you probably move a bit, maybe just a millimeter, from the original location to the location you later inject,” Dr. Cohen said.

A recent report also shows that it is possible to puncture and get into a vessel with small cannulas — the injectors aspirated blood despite using a cannula.

Understanding and Using Biosimilars

One of the only things the dermatology community knows about biosimilar use is that there are many unknowns. Still, biosimilars are on dermatologists’ radars as having the potential to lower the high costs of biologic treatments for chronic skin diseases, including psoriasis.

There also are misperceptions—even among dermatologists—about what biosimilars are and if these drugs can be used to treat patients, according to Leon H. Kircik, M.D., clinical associate professor of dermatology at Indiana University School of Medicine, Indianapolis; clinical associate professor of dermatology at Mount Sinai Medical Center, New York City; and medical director of Physicians Skin Care in Louisville, Ky. who presented “Biosimilars: What You Need to Know” at the Orlando Derm Aesthetic and Clinical conference in Miami, Fla., in January 2017.

Misperception number one

The first misperception is that biosimilars are generic biologics. They’re not, he says.

“You cannot have a generic of a biologic because every biologic is made differently. So, it is important for everybody to understand that biosimilars are not generics,” says Dr. Kircik,

As a result, the approval process for biosimilars is different for that of generics. Biosimilars came about because of the Biologics Price Competition and Innovation Act of 2009, which passed in Congress as a provision of the Affordable Care Act. Biosimilars have an abbreviated licensure pathway, but it’s a different pathway compared to a generic.

“Biopharmaceuticals are biopolymers of organic molecules that are manufactured in living systems. Function is based not only on the amino acid number and sequence but also on posttranslational modification (e.g. glycosylation) that are added by virtue of manufacture in living systems.”

Complexities and blurred lines

The FDA’s definition of a biosimilar, according to Dr. Kircik is, “A biological product that is highly similar to the reference product, notwithstanding minor differences in clinically inactive components. There are no clinically meaningful differences from the reference product in terms of the safety, purity, and potency”

“Those are very vague terms,” Dr. Kircik says.

The first biosimilar (not for use in dermatology), Zarxio [Sandoz], was FDA approved in March 2015. Zarxio is biosimilar to Neupogen (Amgen, filgrastim)1

More than a year later, the first biosimilar to have dermatologic indications received FDA approval—a biosimilar of infliximab, by the name of Inflectra (Celltrion). Interestingly, Inflectra, a biosimilar to Janssen Biotech’s Remicade, has an indication for psoriasis but no data on dermatologic disease, including psoriasis, Dr. Kircik says.

Nasal Reconstruction After Surgery

Options for repairing nasal defects after skin cancer surgery should be based on location, size and depth of the defect, as well as patient preference.

“If the defect is centrally located in the alar groove, you may want natural healing to occur,” says Joel L. Cohen, M.D., associate clinical professor of dermatology at the University of Colorado in Denver, and director of AboutSkin Dermatology in Greenwood Village and Lone Tree, Colo. He spoke with Dermatology Times prior to his presentation on skin cancer nasal reconstruction at the recent Orlando Dermatology Aesthetic & Clinical Conference (ODAC) in Miami.

“In such a case, the natural concavity is often recapitulated by simply letting the skin granulate, without the need for any sutured repair.”

However, in many instances of nasal reconstruction, dermatologists have to decide which procedure will achieve the best aesthetic outcome and also, the level of wound care that can be managed by the patient.

FDA Approval: Corticosteroid-Sparing Topical for Eczema

The FDA announced it has approved Eucrisa (Anacor Pharmaceuticals, crisaborole) ointment to treat mild to moderate eczema in patients two-years-of-age and older.

Applied twice daily, Eucrisa is a phosphodiesterase 4 (PDE-4) inhibitor. Its precise mechanism of action in atopic dermatitis, however, isn’t known, according to an FDA press release.

“We welcome this corticosteroid-sparing topical option,” says Elaine C. Siegfried, M.D., professor of pediatrics and dermatology at Saint Louis University, Cardinal Glennon Children’s Hospital, St. Louis, Mo. “The other two alternatives (pimecrolimus cream and tacrolimus ointment) carry black box warnings and labelled limitation on duration of use. Although most pediatric dermatologists prescribe these medications in infants and children without long-term safety concerns, prescribing Eucrisa is not hampered by this medicolegal burden. However, cost and access could be a limitation.”

Adam Friedman, M.D., associate professor of dermatology and director of translational research in dermatology at George Washington School of Medicine and Health Sciences, tells Dermatology Times that this most recent approval represents the exciting first of hopefully many new approved therapies for an exceedingly common disease state, which until recently was largely ignored.

“I envision crisaborole being used in a similar manner to calcineurin inhibitors, both as proactive treatment for affected delicate areas like the eyelids, face, body folds, groin or mild disease elsewhere. But, more importantly, [I envision it] as preventative maintenance therapy for disease areas that recur frequently after topical steroid use has been discontinued (though without the baggage of a black box warning and possible substance P induced burning at the onset of use),” he says.

Dr. Friedman, who is presenting on the topic of eczema at the January 16 to 19, 2017 Orlando Derm Aesthetic and Clinical conference in Miami, Fla., says this approval, however, should not overshadow the basic and requisite elements for properly managing this often chronic condition. These basics are: clear patient education on a broad range of topics, including realistic expectations; proper soap, moisturizer and treatment use; and myths about treatment safety, in order to gain the patient’s confidence, which in turn, increases the likelihood of regimen compliance, according to Dr. Friedman.

Taming Atopic Dermatitis and Managing Expectations

Tactics for managing patients with atopic dermatitis can go a long way to educate patients, set realistic expectations, and devise strategies for existing therapies, even as clinicians await some promising agents expected on the market soon.

“The good news is this is the Age of Eczema. In the last couple of years we’ve seen an explosion in the literature,” Adam Friedman, MD, of the department of dermatology, George Washington University, Washington, D.C., said at the Orlando Dermatology Aesthetic and Clinical Conference. Some of this research is spurring new therapeutics. a phosphodiesterase 4 inhibitor.

Crisaborole ointment, 2% (Eucrisa), a phosphodiesterase 4 inhibitor, was approved by the Food and Drug Administration in December 2016 for treating patients aged 2 years and older with mild to moderate AD, for example. It is a novel, nonsteroidal anti-inflammatory and the first prescription agent approved in the United States for atopic dermatitis in more than 10 years.

Dr. Friedman has no personal experience with crisaborole, which just became available. “But the data look encouraging. From what I’ve seen this may be a nonburning alternative to calcineurin inhibitors. It will be interesting to see how this will fit in our practices.”
