Nasal polyps are noncancerous growths that form in the lining of the nose or sinuses. They are typically soft, painless, and range in size from a few millimeters to several centimeters. While small nasal polyps may not cause any symptoms, larger ones can obstruct the nasal passages and lead to breathing difficulties, reduced sense of smell, frequent sinus infections, and other issues.
The exact cause of nasal polyps is not fully understood, but they are commonly associated with chronic inflammation of the nasal passages and sinuses, a condition known as chronic rhinosinusitis. This inflammation can be triggered by various factors, including allergies, asthma, recurring infections, certain medications (such as aspirin and nonsteroidal anti-inflammatory drugs), and genetic predisposition.
The treatment of nasal polyps typically involves a combination of medications and, in some cases, surgery. Medications may include nasal corticosteroids to reduce inflammation, antihistamines to relieve allergy symptoms, and antibiotics to treat bacterial infections. In cases where medications alone are ineffective or if the polyps are large, surgery may be recommended to remove them.
Surgical options for nasal polyps include endoscopic sinus surgery (ESS) and functional endoscopic sinus surgery (FESS). These procedures involve using a thin, flexible tube with a camera and small instruments to remove the polyps and clear blocked sinuses. ESS and FESS are minimally invasive techniques that can often be performed on an outpatient basis, allowing for quicker recovery compared to traditional open surgery.
In addition to medical and surgical treatments, lifestyle modifications can help manage nasal polyps and reduce the risk of recurrence. This may include avoiding known triggers such as allergens and irritants, practicing good nasal hygiene (such as using saline nasal rinses), and managing underlying conditions such as allergies and asthma.
While nasal polyps can be bothersome and may require ongoing management, most cases can be effectively treated with a combination of therapies. However, it’s important for individuals with nasal polyps to work closely with their healthcare providers to develop a personalized treatment plan based on the severity of their symptoms and any underlying conditions. Regular follow-up care is also important to monitor for recurrence and adjust treatment as needed.

Nasal polyps, benign growths that develop in the mucous membranes lining the nasal passages or sinuses, can vary greatly in size and number. These growths are often associated with chronic inflammation of the nasal and sinus tissues, a condition known as chronic rhinosinusitis. While the precise mechanisms underlying the formation of nasal polyps are not fully understood, several factors are believed to contribute to their development.
Chronic inflammation plays a central role in the pathogenesis of nasal polyps. This inflammation can result from various factors, including allergic rhinitis, asthma, recurring infections, and certain medications. Allergic rhinitis, commonly referred to as hay fever, occurs when the immune system overreacts to allergens such as pollen, dust mites, or pet dander, leading to inflammation of the nasal passages. Similarly, asthma, a chronic respiratory condition characterized by inflammation and narrowing of the airways, is often associated with nasal polyps.
In addition to allergic and immunologic factors, genetic predisposition may also play a role in the development of nasal polyps. Certain individuals may have a genetic susceptibility to chronic inflammation, making them more prone to conditions such as chronic rhinosinusitis and nasal polyps. Furthermore, there is evidence to suggest that specific genetic variations may increase the risk of developing nasal polyps in response to environmental triggers.
Medications can also contribute to the development or exacerbation of nasal polyps. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as aspirin and ibuprofen, have been implicated in a condition known as aspirin-exacerbated respiratory disease (AERD), which is characterized by nasal polyps, asthma, and sensitivity to aspirin and other NSAIDs. The exact mechanism by which NSAIDs trigger inflammation and nasal polyp formation in susceptible individuals is not fully understood but is thought to involve alterations in the metabolism of arachidonic acid and the production of pro-inflammatory mediators.
The symptoms of nasal polyps can vary depending on their size and location. Small polyps may not cause any symptoms and may be incidentally discovered during a routine nasal examination. However, larger polyps or clusters of polyps can obstruct the nasal passages, leading to symptoms such as nasal congestion, difficulty breathing through the nose, reduced sense of smell (hyposmia) or loss of smell (anosmia), postnasal drip, facial pain or pressure, and recurrent sinus infections (sinusitis).
Diagnosis of nasal polyps typically involves a thorough medical history, physical examination, and nasal endoscopy, a procedure in which a thin, flexible tube with a camera is inserted into the nasal passages to visualize the extent and location of the polyps. Imaging studies such as computed tomography (CT) scans may also be performed to assess the severity of sinus inflammation and evaluate for other underlying conditions.
Treatment strategies for nasal polyps aim to reduce inflammation, alleviate symptoms, and prevent recurrence. This often involves a combination of medications and, in some cases, surgical intervention. Nasal corticosteroids are the mainstay of medical therapy and work by reducing inflammation and shrinking polyp size. These medications are typically administered as nasal sprays or drops and may take several weeks to achieve maximum effectiveness.
In addition to nasal corticosteroids, other medications may be prescribed to manage symptoms and underlying conditions. Antihistamines can help alleviate allergy-related symptoms, while antibiotics may be necessary to treat bacterial infections that can occur secondary to nasal polyps. In cases where medical therapy alone is insufficient or if the polyps are large and causing significant obstruction, surgical intervention may be recommended.
Endoscopic sinus surgery (ESS) and functional endoscopic sinus surgery (FESS) are minimally invasive procedures used to remove nasal polyps and open blocked sinus passages. During these procedures, a thin, flexible endoscope is inserted into the nose, allowing the surgeon to visualize and remove polyps using small instruments. ESS and FESS are typically performed on an outpatient basis and offer the advantage of shorter recovery times compared to traditional open surgery.
Lifestyle modifications may also play a role in managing nasal polyps and reducing the risk of recurrence. This may include avoiding known triggers such as allergens and irritants, practicing good nasal hygiene (such as using saline nasal rinses), and managing underlying conditions such as allergies and asthma. Regular follow-up care with a healthcare provider is essential to monitor for recurrence, adjust treatment as needed, and ensure optimal long-term management of nasal polyps.
