What is Nasal Crusting a Symptom of?
Nasal crusting can be an uncomfortable and persistent condition, often showing an underlying issue within the nasal passages or sinuses. While some may experience occasional crusting due to dry air or minor colds, chronic or severe crusting could point to more significant problems, such as septal perforation, infections, or inflammatory conditions. In this article, we will explore the most common causes of nasal crusting, associated symptoms, and available treatment options to help alleviate this condition.
Nasal crusting occurs when the moist tissues inside the nose become dry, resulting in the formation of hard, dried mucus or scabs. This build-up can lead to discomfort, congestion, and, in some cases, nosebleeds. Understanding the root cause of this symptom is essential for proper treatment.

Common Causes of Nasal Crusting
- Septal Perforation
One of the primary causes of nasal crusting is a septal perforation. This condition arises when a hole forms in the nasal septum, the cartilage that divides the nostrils. The septum plays a vital role in keeping airflow and moisture within the nose. When perforated, airflow through the nasal passages becomes turbulent, which dries out the delicate mucosal lining, leading to crust formation. In addition to crusting, septal perforation can cause symptoms such as frequent nosebleeds, whistling sounds during breathing, and nasal congestion. If left untreated, the perforation can enlarge, worsening these symptoms.
Causes of septal perforation include trauma to the nose, prior nasal surgery, long-term use of nasal sprays, or certain medical conditions. Treatment often involves managing the crusting with saline sprays or ointments to keep the nasal tissues moist, while larger perforations may require surgical repair to close the hole and restore normal nasal function.
- Chronic Rhinitis
Chronic rhinitis, a condition marked by the inflammation of the nasal lining, is another common cause of nasal crusting. Rhinitis can be triggered by allergens, infections, or environmental factors such as pollution or smoke. The chronic inflammation leads to excess mucus production, which, when dried, results in crusting inside the nose. Patients with allergic rhinitis may notice increased crusting during allergy seasons or when exposed to specific allergens such as pollen, dust mites, or pet dander.
Managing chronic rhinitis typically involves finding and avoiding allergens, using antihistamines, or applying corticosteroid nasal sprays to reduce inflammation. Humidifying your living environment and using saline rinses can also help prevent nasal crusting associated with rhinitis.
- Chronic Sinusitis
Recurrent or chronic sinus infections can cause sinusitis, which inflames the sinuses and nasal passages. When the sinuses become blocked and infected, the body produces thicker mucus, which can dry out and form crusts inside the nose. Chronic sinusitis sufferers often experience nasal congestion, facial pain, headaches, and post-nasal drip, alongside the crusting. In severe cases, untreated sinusitis can lead to more serious complications, including the spread of infection to nearby structures.
Treatment for sinusitis-induced nasal crusting may include decongestants, antibiotics for bacterial infections, and saline nasal irrigation. In cases of chronic sinusitis, surgery to improve sinus drainage may be recommended.
- Nasal Trauma or Surgery
Any injury to the nose or a history of nasal surgery, such as a deviated septum repair (septoplasty), can lead to scarring and damage to the mucosal lining of the nose. This damage can impair the nose’s ability to stay moist, increasing the likelihood of crust formation. Post-surgical nasal crusting is not uncommon, especially in the weeks following a procedure. However, with proper aftercare, including saline sprays and ointments, this symptom generally improves as the nasal tissues heal.
- Autoimmune Conditions
In rare instances, nasal crusting may be a symptom of an autoimmune disorder. Conditions such as Wegener’s granulomatosis or sarcoidosis can affect the blood vessels and tissues in the nose, leading to chronic inflammation, scabbing, and crusting. Autoimmune conditions affecting the nasal passages often require specialised care and treatment, including the use of immunosuppressive medications to control inflammation and prevent further damage.
- Atrophic Rhinitis
Atrophic rhinitis is a less common but significant cause of nasal crusting. This condition occurs when the nasal mucosa and the structures that support the nasal cavity deteriorate. As a result, the nose becomes excessively dry, and thick crusts form inside. Atrophic rhinitis may lead to an unpleasant odour (ozena) and, in severe cases, nasal deformities. Treatment typically involves the use of nasal moisturisers, saline rinses, and antibiotics to prevent infection. In some cases, surgery may be necessary to restore the function and structure of the nasal cavity.
Symptoms Associated with Nasal Crusting
Apart from the visible formation of crusts inside the nose, patients experiencing nasal crusting may notice added symptoms, depending on the underlying cause. These symptoms can include:
- Dryness and discomfort in the nasal passages
- Frequent nosebleeds
- Nasal congestion or blocked nostrils
- A whistling sound when breathing through the nose
- Pain or pressure in the sinus areas
- Persistent or recurring infections
- Foul-smelling discharge (in cases of infection or atrophic rhinitis)
If nasal crusting is accompanied by these symptoms, it’s crucial to seek medical attention to diagnose the cause and start proper treatment.
Treatment Options for Nasal Crusting
The treatment for nasal crusting varies depending on the cause of the condition. Here are some common treatment strategies:
- Saline Nasal Sprays or Irrigation: Using saline sprays or performing nasal irrigation with a saline solution can help keep the nasal passages moist, soften crusts, and improve mucus drainage. This is particularly helpful in conditions like chronic rhinitis, sinusitis, and septal perforation.
- Topical Ointments: Applying a petroleum-based ointment or antibiotic cream inside the nose can help prevent dryness and protect the nasal lining. These treatments are often recommended for post-surgical crusting or cases where the nasal lining is damaged.
- Humidifiers: Adding moisture to the air with a humidifier can help relieve nasal dryness, especially during colder months or in dry climates. Maintaining a humid environment can reduce crusting and improve overall nasal comfort.
- Medications: Depending on the underlying cause, your doctor may prescribe antihistamines for allergies, corticosteroid nasal sprays to reduce inflammation, or antibiotics to treat infections that contribute to nasal crusting.
- Surgical Treatment: For cases like septal perforation or chronic sinusitis that do not respond to conservative treatment, surgical intervention may be necessary. Septal perforations can be surgically repaired to restore normal airflow and reduce crusting, while sinus surgery can improve drainage and prevent recurrent infections.
