A patient sitting across from me last week pointed at the raw skin around her nose and said that three nights prior she had gone after it with tweezers. Then, half-jokingly, she asked, “So, did you have to get that checked?” In response, I said the truth is mostly no, but sometimes, in a small fraction of cases, absolutely, yes. And there are real and lasting consequences when people do not heed this warning. Because the zone where she pointed, her nose and the skin to either side of it, has been called the “triangle of death” by anatomists for over 100 years. I got a call this past April asking me to break down why, as a source for a story about an influencer whose obsessive skincare habits nearly killed her. And here is that story, with the anatomy.
What Is the Triangle of Death and Where Is It?
Take a triangular imaginary boundary drawn on your face. The apex of that triangle rests at the top bridge of your nose. The base of that triangle is drawn horizontally, stretching from the corners of your lips. This entire region of skin that rests on your nose and connects to the corners of your mouth is what anatomy students refer to as the triangle of death.
As scary as it sounds, that name for such a small section of your face has been earned by its inherent and unique behavior. Anatomically, it operates and responds differently to skin elsewhere on the face or body, and it is not the kind of place for experimentation on yourself with tweezers at midnight.
The Plumbing: Why Veins Here Flow Backward
There is a piece of information most people do not have about the veins on their face. Veins carry blood in one direction only, towards the heart, and nearly all of them have one-way valves inside that stop the blood from slipping backwards. This fact plays a role in why the smallest nick on the toe stays at the toe, instead of traveling the length of your leg. Most veins that surround the triangle of death have no valves, however.
Those veins, through connections with the ophthalmic and facial veins, drain into the large cavernous sinus reservoir of blood located at the base of the skull, and this pool of veins is located next to the eyes and the brain. Without valves, there is no one-way traffic rule. Therefore, if infection enters the area from squeezing a pimple or using an unsterile needle, an open pathway exists to work its way backward into the eye socket and the cavernous sinus, instead of being cleared harmlessly downward. That backward movement, and this pathway for blood, is not present almost anywhere else on the human body.
Just How Serious Is It?
Let me clarify this point precisely, because precision offers comfort much more than scare stories do. The complication is cavernous sinus thrombosis, an infection within the reservoir of blood behind the eyes. Back before antibiotics became common treatment for such a condition, cavernous sinus thrombosis was nearly always a death sentence, and the history behind that tragic fact earned the triangle its terrifying name.
Today, however, that complication is rare. If an infection occurs here and travels to the cavernous sinus, the odds are around 0.2 to 0.5 percent. And thanks to antibiotics, the condition is no longer fatal with nearly 100 percent probability, but it is still serious, and treatable when diagnosed early. And that is the accurate, and reassuring, summary: uncommon, still serious, and treatable if addressed quickly. This known medical fact ought to guide your behavior rather than spark panic with every blemish.
How Trouble Starts in the Triangle
Generally speaking, the triangle of death rarely bothers anyone when people leave it alone. The problems I witness are brought about when people physically apply force to it. Common culprits I observe in the practice room are pinching deep zits with fingernails, plucking an ingrown hair from the mustache area, forcibly excavating blackheads along the side of the nose, or draining cysts yourself at the bathroom counter.
Among the newest problems are DIY kits ordered online, lancets, comedone extractors and derma-rollers, as well as injections of dermal fillers into the triangle by non-physicians, often on patients already taking strong retinoids and acids that thin the skin. The common thread is unsterile pressure that pushes bacteria further down into the tissues, as opposed to letting the infection clear up the facial pathways and out. That is how the danger starts, without exception.
How I Avoid the Problems When I Operate
What tends to surprise most of my patients is how I can be operating right inside this region routinely and safely. With a deep plane or endoscopic deep plane facelift, a surgeon cuts directly through the triangle. Safety is paramount in these operations, and it results from a multitude of obsessive safety practices. For any face procedure, the entire triangle is rigorously scrubbed using a strong surgical antiseptic. Every instrument that touches the skin must be sterile, the surgical team is gowned and gloved, the area of operation is covered and draped, and the surgical method is intended to prevent any bacteria being pushed down into deeper tissue planes.
Infection control is not a step that comes in later during the operation; it is a huge component of all plastic surgery. I was fortunate enough to train as part of the team at the Mayo Clinic plastic surgery fellowship, where infection control was at the top of the curriculum. That training has continued as I have spent years instructing plastic surgery residents as a Clinical Associate Professor of Plastic Surgery at Texas Tech University Health Sciences Center. This level of sterile procedure is why anything done within the triangle, including fillers and Botox, should be handled by a board-certified surgeon rather than a technician working unsupervised. Not because their hands are more elegant or graceful, but because they enforce sterile standards and treat that centimeter of skin as the delicate, dangerous portal it is.
What It Looks Like If You Must Seek Treatment in This Zone
Most skin blemishes around the triangle of death heal harmlessly, like any other. The warning comes when what is simply a blemish acts abnormally. Watch for redness and irritation surrounding a spot moving outwards instead of fading back inwards, especially in the direction of your eye, significant and increasing swelling over a few hours, the onset of fever, debilitating head pain more intense than any typical headache you may ever endure, any altered vision or double vision, or one of your eyes beginning to bulge or droop slightly or stopping to move normally.
Those symptoms are not to be dismissed as spa-like problems. This cluster requires a visit to an emergency room that day, because the timeliness of antibiotic therapy is critical. For the day-to-day, keeping the area healthy is as simple as people imagine. Leave the triangle strictly alone, combat acne with real dermatology rather than digging, keep the skin clean, and for anything invasive, like extractions, lesions, or any form of procedure in the area, please see a medical professional for proper care.
