Nasal cauterization is a common, minimally invasive medical procedure used to stop frequent or severe nosebleeds (epistaxis). The technique involves sealing off problematic blood vessels inside the nasal passages to prevent recurrent bleeding. This process creates a small, controlled burn, often performed in a doctor’s office, to permanently close the fragile vessel causing the issue. Cauterization manages nosebleeds that are not controlled by standard at-home care.
Why Nasal Cauterization Is Performed
The primary reason for this treatment is recurrent nosebleeds that do not respond to simple home remedies. Most nosebleeds originate from the anterior, or front, part of the nose in Kiesselbach’s plexus, a dense network of small, superficial blood vessels easily ruptured near the surface.
Chronic irritation contributes to the fragility of these vessels, often making cauterization necessary. Factors include frequent nose picking, forceful nose blowing, or exposure to dry air, which can damage the delicate nasal lining. The drying of mucous membranes exposes blood vessels, making them prone to breakage.
Cauterization is reserved for patients with frequent bleeding episodes where conservative measures, such as nasal ointments, saline sprays, and humidifiers, have been unsuccessful. The goal is to create a small area of scar tissue that provides a robust seal over the bleeding site.
Steps of the Cauterization Procedure
The procedure begins with applying topical agents to prepare the nasal passage. A topical decongestant, which shrinks blood vessels, is applied along with a local anesthetic to numb the internal lining of the nose. This numbing agent minimizes discomfort during the treatment.
Once numb, the clinician uses a light source to locate the precise bleeding point. The most common method is chemical cautery, using a silver nitrate stick. The silver nitrate is applied directly to the vessel for a few seconds, creating a controlled, superficial chemical burn that seals the vessel.
The treated area instantly develops a gray or black appearance, which is called an eschar, confirming the vessel has been sealed. Care is taken to avoid applying the chemical to too large an area or to both sides of the septum simultaneously, which could cause tissue damage. A less common method, electrical or thermal cautery (electrocautery), uses a specialized device to generate heat, which is then used to seal the vessel. This thermal method is often reserved for larger or more persistent vessels, sometimes requiring it to be performed under general anesthesia in a surgical setting.
Recovery and What to Expect Afterward
Following the procedure, patients should expect a short period of healing and must follow specific aftercare instructions. Mild discomfort, stinging, or itching in the nose is common for the first three to five days as the treated area recovers. Simple over-the-counter pain relievers, such as acetaminophen, are recommended to manage this mild pain.
The formation of a scab or crust, known as an eschar, over the cauterized site is a normal part of healing and should be left undisturbed. Patients must avoid picking at or forcefully blowing the nose for one to two weeks, as this can dislodge the protective scab and cause bleeding to recur. Patients are also advised to avoid strenuous activity, heavy lifting, or any activity that significantly increases blood pressure for about one week.
To aid healing and keep the nasal lining moist, doctors recommend applying an antibiotic or petroleum-based ointment, or using a saline nasal spray several times a day. This prevents the area from drying out, which can slow recovery and increase the likelihood of re-bleeding. Minor risks of the procedure include a temporary gray stain on the skin from the silver nitrate, infection, or the possibility that the nosebleed may still recur, which might necessitate a second treatment.
