Vascular occlusion in the nose: signs and initial management
Vascular occlusion in the nose is the interruption of flow in a nasal artery, or in one of its branches, during or after a filler, generally in nonsurgical rhinoplasty. The product can enter the vessel or compress it from outside. The supplied skin becomes ischemic and, without timely reversal, can progress to necrosis of the tip, ala or dorsum.
The nose is one of the highest vascular risk areas of the face, alongside the glabella. Beyond local necrosis, the nasal arterial network communicates with the circulation of the eye, which links nonsurgical rhinoplasty to visual complications. This guide is a review: risk anatomy, signs and how to organize the initial management. It includes no doses, dilutions or injection technique; those follow current guidelines and the decision of the licensed professional, according to the rules of their professional council in Brazil. The general concept is in the entry vascular occlusion.
Why is the nose a high-risk area?
Four features add up:
- Two circulations meet. The nose receives branches from the facial artery, from the external carotid, and from the ophthalmic artery, from the internal carotid. The dorsal nasal artery joins the angular artery on the side of the nose. Product that enters this network can travel toward the orbit.
- Adherent skin and little room. Over the dorsum and tip, the skin has little distensibility. The gel raises local pressure and can compress vessels even from outside them.
- Terminal territory. The tip and ala depend on end branches, with less alternative circulation. Ischemia there progresses faster to skin injury.
- Anatomical variation. Course, caliber and depth of the arteries change from person to person and from one side to the other. There is no plane that is safe for everyone.
| Artery | Origin | Territory in the nose |
|---|---|---|
| Dorsal nasal | Ophthalmic (internal carotid) | Root and dorsum, networked with the opposite side |
| Angular | Facial (external carotid) | Side of the nose to the inner corner of the eye |
| Lateral nasal | Facial | Ala and lateral wall |
| Columellar branch | Superior labial, from the facial | Columella and tip |
| External nasal | Anterior ethmoidal, from the ophthalmic | Dorsum, exiting between bone and cartilage |
What about someone who has had a rhinoplasty?
The search "rhinoplasty necrosis" mixes two situations. The first is skin necrosis after the surgery itself, which is the surgeon's matter. The second is the one that matters here: the patient who has had surgery and seeks nonsurgical rhinoplasty. Previous surgery alters the vascular anatomy, leaves fibrosis and reduces the room and blood supply of the nasal skin, and for that reason it appears in reviews as a risk factor for occlusion and necrosis. Always ask, record and weigh the indication with more caution. In some cases, the safest answer is not to treat.
What are the signs of vascular occlusion in the nose?
The signs change over time. The table organizes what usually appears in each phase.
| Phase | Most cited signs | Where to look |
|---|---|---|
| During injection | Sudden blanching, disproportionate pain | Tip, ala, dorsum, side of the nose |
| Minutes | Net-like violet color (livedo), slow capillary refill, coldness | Compare with the neighboring skin and the opposite side |
| Hours | Darkening, increasing pain, localized swelling | Territory that may advance to the glabella, the corner of the eye and the upper lip |
| Day one to three | Blisters, pustules, dark scabs | Tip and ala, following the vascular course |
| Following days | Established necrosis, ulceration | Risk of tissue loss, scarring and deformity of the ala |
Pain can be masked by the anesthetic in the product or by prior local anesthesia. Observing color and capillary refill is worth as much as the patient's complaint.
How do you tell it from swelling, ecchymosis and infection?
| Condition | How it usually presents | Difference from occlusion |
|---|---|---|
| Expected swelling | Diffuse puffiness, normal color, mild pain | Capillary refill preserved, no pallor or violet net |
| Ecchymosis | Well-defined purple patch at the entry point, changes color over the days | Does not blanch, does not follow an arterial territory, stable pain |
| Reactive erythema | Uniform redness right after the procedure | Fades within hours, no livedo |
| Infection | Warmth, redness, pain and discharge, generally days later | No initial pallor, no net pattern |
| Vascular occlusion | Pallor, then a violet net-like color, increasing pain, blisters on the tip or ala | Slow capillary refill and progression over hours |
When in doubt, the usual guideline advice is to treat it as a suspected vascular event. In the nose, the margin for waiting is even smaller.
What to do when occlusion is suspected: initial management
At review level, complication protocols usually organize the first response like this:
- Stop the injection immediately and do not inject more product.
- Check vision and neurological signs first of all. If there is any change, urgent referral comes first.
- Assess the skin: color, capillary refill, temperature and extent, including the glabella, the corner of the eye and the upper lip.
- Activate the clinic's written protocol, with the complication kit at hand.
- With hyaluronic acid, use hyaluronidase across the whole ischemic area, according to current guidelines and the professional's judgment, reassessing perfusion at short intervals.
- Adjuvant measures described in protocols have variable evidence and do not replace the enzyme. Systemic medication, when indicated, is a medical decision.
- Record everything: start time, signs, serial photos, what was done and when.
- Do not discharge the patient without signs of reperfusion, with follow-up and a contact channel defined.
- Refer if there is worsening, an extensive area, signs of infection or any visual or neurological sign.
How to organize the enzyme, stock and team training is covered in hyaluronidase in the clinic, and the regulatory status of the product in hyaluronidase at ANVISA (Brazil's health regulator). The logic of management is the same as described in vascular occlusion in the lip, with the difference that, in the nose, monitoring vision is mandatory from start to finish.
What comes after the acute phase?
Even with reperfusion, the nasal skin needs close follow-up. Areas that suffered ischemia can flake, form scabs and change color for weeks. When there is necrosis, wound care comes in, with medical evaluation, along with a long-term plan for the scar and the contour of the tip and ala, sometimes with the surgeon's involvement.
- Frequent follow-ups, with photos in the same standard.
- Easy contact with the professional in the first few days, including at night.
- Honest communication from the first sign, without downplaying.
- A review of the case afterward: product, volume, the nose's history and what changes in future visits.
How can the risk be reduced in the nose?
No measure eliminates the risk. At review level, the ones that come up most:
- Know the anatomy and the variation, without relying on a fixed "safe zone".
- Investigate rhinoplasty, trauma and previous fillers, and weigh the indication with more caution in those cases.
- Prefer a reversible material and conservative volumes per session.
- Have hyaluronidase in the clinic, in date, before starting.
- Watch the skin and ask about vision throughout the injection.
- Inform the patient about warning signs for the first hours and days.
- Mention occlusion, necrosis and vision loss in the informed consent.
Indications, limits and what patients usually ask for are on the area page nose.

Frequently asked questions
Can hyaluronic acid in the nose cause necrosis?
It can, although it is rare. The nose has tightly adherent skin, little room for product and terminal arteries at the tip and ala. If the gel enters a vessel or compresses it, the supplied skin becomes ischemic and can progress to necrosis without timely treatment.
What are the signs of necrosis in the nose after filler?
The first signs are usually sudden pallor, disproportionate pain and, later, a purplish net-like color on the tip, ala or dorsum. In the following hours and days, darkening, blisters and scabs may appear in the territory of the artery.
Can someone who has had a rhinoplasty get nonsurgical rhinoplasty?
It is a situation that calls for extra caution. Surgery alters the anatomy, leaves scarring and reduces the room and blood supply of the nasal skin, which is described as a risk factor. The indication is individual, after a careful assessment.
Can an occlusion in the nose affect vision?
It can, in rare cases. The arteries of the nose communicate with the ophthalmic artery, and the product can reach the circulation of the eye. Any visual change during or after the procedure is an emergency, with immediate referral.
