Cannulas – Development in Technique and Safety

SoftFil 27 Gauge Cannula

What is a Cannula?

A cannula is a flexible, blunt tipped instrument that is used for injecting, whereas a needle is a sharp tool, that pierces the skin (see image on left).  This begs the question, if a cannula is blunt, how exactly is it used for injecting?  With a cannula, you must first make a starter hole with a needle, and then the cannula is inserted into that hole.  You may be asking, why go through the trouble of first making a hole with a needle, and then using a cannula?  Why not simply use a needle?

The Advantages of a Cannula

Decreased Trauma

There are several advantages of using a blunt tipped cannula in aesthetic treatments.  Firstly, a cannula is typically much longer than a needle, and it is flexible.  This increased length and flexibility allows you to create a single injection point, and push the cannula the skin, reaching a much greater area than a needle can.  To cover that same area with a needle, it would require multiple injection points.  By having only one injection point, you are reducing trauma to the tissue, which can lead to decreased bruising, and reduced downtime.  This is especially true for sensitive areas, like under the eyes.

Reduced Risk of Complications

Needles are indiscriminate when it comes to your tissues.  Their sharp tips will pierce through anything, including veins.  However, because the tip of a cannula is blunt, you avoid damage to veins and arteries, by moving around them.  This decreased vascular damage can reduce bruising and the risk of complications.

Improved Results

Because cannulas are longer and more flexible than needles, they allow for broad, sweeping strokes, which can create a softer more natural look.  Much like giving a painter multiple brushes, cannulas allow injectors an additional tool.  This tool allows them  to add to their artistry and give patients their desired aesthetic appearance they are looking for.

Disadvantages of Cannulas

Training and Cost

Every box of filler comes with a needle that is intended to be used for injection of filler.  Adding cannulas to your treatment results in an increased cost to the practitioner, with a cost of about $5-7 per cannula. Also, because dermal fillers were approved only with the use of needles, needle injected training is the only training provided by the dermal filler companies, such as Allergan, and Galderma.  If a doctor is looking to learn more about using cannulas in their treatments, they will have to seek that training out, often at a cost to the doctor.  This additional training, cost, and new learning curve often discourages doctors from learning how to use cannulas in aesthetic treatments.


While cannulas shouldn’t completely replace needles in the injection of aesthetic dermal fillers, in order to best serve the beauty goals of our patients, aesthetic doctors should incorporate a wide range of tools in their practice.  Adding cannulas to your aesthetic arsenal can increase patients results, while reducing downtime and complications.

Holiday Health Tips

How to Avoid Holiday Stuffing

The holiday season is fast approaching, and the first thing that comes to every ones mind is holiday weight gain, the seemingly unavoidable result of all of that holiday cheer.  But do not despair, all is not lost.  It is quite possible to have an amazing Thanksgiving, without the excess stuffing that often comes all with it.  Here are a few simple tips to keep you focused during these dietarily difficult times.

Start with Vegetables

This tip is great all year round, but does wonders when you are filling up your Thanksgiving plate.  Start adding your vegetables to your plate first.  Sure, the stuffing gets all of the holiday glory, but vegetables should always be your centerpiece of your food plate, with meat and starches rounding it out.  That brings us to tip 2!

Corn is NOT a Vegetable

I know its seems like one, and maybe it taste like one, but in your stomach, it acts like a grain.  Also, even though a potato is a vegetable, thanksgiving mashed potatoes may not be the best choice.  A roasted sweet potato is a much healthier choice.  Feel free to be sinful and and some butter.  Do try to add something green to your plate, brussel sprouts, string beans and brocolli are great holiday choices.   If you are horrified by the thought, try adding some bacon to the dish, or if even that doesn’t seem appealing, hold your nose, shove them in, and in time you will learn to love them.

Use a Smaller Plate

Don’t grab a gigantic plate and fill it until food is spilling onto the floor.  Grad a smaller plate, and try to let psychology do it’s thing.  You always go for seconds.

This is NOT a Professional Eating Challenge

You do not get a prize for eating so much that you almost pass out on your way to the couch. The food is not going anywhere.  There are ALWAYS leftovers.  Let them be leftovers.  Let your stomach live to fight another day.  Eat a reasonable portion, and celebrate the rest of the day in comfort, with your pants buckled.

Turkey is Your Friend

White meat, dark meat?  Who cares, it’s all good for you.  Don’t skimp, that’s why they sell 22lb turkeys.

It’s a Perfect Time for a Workout

Leverage those holiday carbs into some muscle building energy.  While I don’t recommend working directly after your Thanksgiving meal, Friday is the perfect time to use your stuffing fueled, glycogen filled muscles and lift some weights.  Use that extra energy to go big at the gym, and build some fat burning muscle.

These are just a few tips to keep you on the right track during the holidays.  Feel to let us know what you think, or add your own.
