Nasal polyps are benign, painless, non-cancerous growths that form in the lining of the nasal passages or sinuses due to chronic inflammation. These growths often resemble teardrops or grapes and can range in size from small, hidden polyps to larger ones that obstruct airflow. When nasal polyps become large or numerous, they can lead to significant symptoms such as nasal congestion, difficulty breathing, decreased sense of smell, and sinus infections.
While most nasal polyps do not require surgery, removal may be necessary if the polyps cause chronic symptoms or are unresponsive to medication. Nasal polyp removal can help improve nasal airflow, reduce recurrent sinus infections, and enhance the patient’s quality of life.
This guide will provide an in-depth exploration of the causes, risk factors, symptoms, diagnostic process, treatment options, prevention strategies, complications, and living with nasal polyps after removal.
Nasal polyps develop due to chronic inflammation of the mucous membranes inside the nasal passages and sinuses. Although the exact cause remains unclear, there are several known factors that contribute to their formation:
Chronic Sinusitis (Sinus Infection):
Persistent inflammation or infection of the sinuses is one of the most common causes of nasal
polyps. This long-term inflammation can cause the sinus lining to swell, leading to polyp
development.
Asthma:
People with asthma, especially those with aspirin-exacerbated respiratory disease (AERD), are
more likely to develop nasal polyps. AERD is characterized by severe asthma, chronic
sinusitis, and sensitivity to aspirin.
Allergic Rhinitis (Hay Fever):
Allergies that trigger inflammation in the nasal passages can promote polyp growth. This is
often seen in individuals with long-term exposure to allergens such as pollen, dust mites,
mold, or pet dander.
Cystic Fibrosis:
This genetic condition causes thick mucus in the respiratory system, making individuals with
cystic fibrosis more susceptible to nasal polyps.
Chronic Respiratory Infections:
Repeated respiratory infections, especially in children, can contribute to the development of
polyps.
Several factors may increase the likelihood of developing nasal polyps:
Age: Nasal polyps are more common in adults, particularly those over 40.
Family History: A genetic predisposition may make some individuals more prone to polyps.
Smoking: Smoking irritates the airways and can lead to chronic inflammation, increasing the risk of polyp formation.
Environmental Irritants: Exposure to pollutants, dust, chemicals, or second-hand smoke can increase the likelihood of polyps.
Immune System Disorders: Conditions that weaken the immune system or lead to chronic inflammation may promote polyp growth.
The symptoms caused by nasal polyps are often related to nasal obstruction, sinus pressure, and reduced airflow. Common signs include:
Chronic Nasal Congestion:
Difficulty breathing through the nose due to polyps obstructing airflow.
Decreased Sense of Smell (Hyposmia):
Nasal polyps often block the olfactory nerves, which are responsible for the sense of smell.
Postnasal Drip:
The sensation of mucus dripping down the back of the throat, which may cause irritation and
coughing.
Frequent Sinus Infections:
Polyps can block the sinuses, leading to recurring sinus infections (sinusitis).
Facial Pressure or Pain:
A feeling of fullness or pressure in the forehead, eyes, or cheeks.
Snoring or Sleep Apnea:
Nasal obstruction can lead to snoring or disturbed sleep patterns due to difficulty breathing
at night.
Large Polyps:
Large polyps or those causing significant nasal obstruction may require surgical intervention
for removal.
Resistant Symptoms:
If symptoms such as nasal congestion, sinus infections, or decreased sense of smell do not
improve with medical treatment, surgery may be necessary.
Impact on Quality of Life:
When nasal polyps significantly affect daily activities, such as sleep, work, or social
interactions, surgery is often considered to improve overall quality of life.
Physical Examination:
An ENT specialist will conduct a thorough examination of the nose and sinuses, often using a
nasal speculum to check for swelling or polyps.
Endoscopy:
A flexible nasal endoscope is commonly used to visualize the nasal passages and sinuses in
detail. This allows the physician to identify the size and location of polyps and assess the
degree of obstruction.
CT Scan of the Sinuses:
A CT scan provides detailed images of the sinuses, helping to assess the extent of polyp
involvement and any associated sinus infection or anatomical abnormalities.
X-rays:
Occasionally used to assess the degree of sinus congestion and blockages.
In rare cases where there is concern about the nature of the polyp (e.g., suspicion of malignancy), a biopsy may be performed to rule out cancer or other serious conditions.
Before resorting to surgery, the following medical treatments may be tried:
Nasal Corticosteroids:
These anti-inflammatory medications are often the first line of treatment. Nasal
corticosteroids help reduce polyp size and alleviate symptoms.
Oral Steroids:
Short-term use of oral steroids may be prescribed for larger polyps or severe inflammation to
shrink the polyps.
Saline Nasal Irrigation:
Rinsing the nasal passages with a saline solution can help remove mucus and allergens,
reducing inflammation and easing symptoms.
Antihistamines and Decongestants:
These medications can help relieve symptoms of nasal congestion caused by allergies.
Endoscopic Polypectomy:
The most common method for removing nasal polyps is through nasal endoscopy. This minimally
invasive procedure involves using a small camera and instruments to remove the polyps through
the nostrils, avoiding external incisions.
Functional Endoscopic Sinus Surgery (FESS):
For patients with chronic sinusitis, FESS can be used to clear sinus blockages and remove
polyps to improve sinus drainage.
Laser Surgery:
In some cases, a laser may be used to shrink or vaporize polyps.
Surgical Excision (Rare):
If polyps are large or recurrent, a more extensive surgical approach may be necessary, where
polyps are removed directly from the nasal cavity.
Control Allergies:
Managing allergies through antihistamines or immunotherapy can help reduce inflammation and
prevent the formation of new polyps.
Avoiding Irritants:
Reducing exposure to environmental factors such as smoke, pollution, and chemicals can
decrease the risk of polyp recurrence.
Good Nasal Hygiene:
Regular saline nasal irrigation and the use of humidifiers can keep the nasal passages moist,
reducing the likelihood of polyps returning.
Follow-Up Appointments:
Regular visits to an ENT specialist are essential to monitor healing and ensure that polyps
do not recur.
Use of Nasal Steroids:
Continued use of nasal corticosteroid sprays may be recommended to reduce inflammation and
prevent recurrence.
Voice Rest and Limited Physical Activity:
Patients are typically advised to avoid strenuous activity and heavy lifting for a few weeks
after surgery.
While nasal polyp removal is generally a safe procedure, there are potential complications:
Nasal Bleeding:
Minor bleeding is common, but major bleeding is rare.
Infection:
An infection can develop post-surgery, requiring antibiotics.
Recurrence of Polyps:
Nasal polyps can recur, especially in patients with underlying conditions like asthma or
allergies.
Scarring:
In some cases, scarring in the nasal passages may occur, which can cause new blockages.
Altered Sense of Smell:
Some patients may experience changes in their sense of smell after surgery.
After nasal polyp removal, most patients experience significant symptom relief, including improved breathing and a better sense of smell. However, managing the underlying conditions contributing to polyp formation is crucial to preventing recurrence.
Postoperative Appointments:
Regular follow-ups with an ENT specialist ensure proper healing and early detection of any
recurring polyps.
Lifestyle Changes:
Adopting a healthy lifestyle, avoiding allergens, and refraining from smoking are important
for long-term sinus health.
Voice and Breathing Therapy:
Speech and breathing exercises can help patients adjust to improved airflow and vocal
function after surgery.
Nasal polyps are non-cancerous, soft, painless growths that develop in the lining of the nasal passages or sinuses due to chronic inflammation. They are often associated with conditions such as chronic sinusitis, asthma, and allergies.
Removal is typically necessary when polyps cause persistent nasal blockage, breathing difficulties, sinus infections, loss of smell, or contribute to other complications. Medications may not always shrink large or multiple polyps, so surgical intervention may be required.
Nasal polyp removal is typically done using a procedure called functional endoscopic sinus surgery (FESS). A small endoscope is inserted through the nostrils to visualize and remove the polyps using specialized surgical instruments.
The procedure is usually done under general or local anesthesia, so there is no pain during the surgery. Post-surgery, mild discomfort, nasal congestion, or a sore throat is common but typically resolves with proper care.
The procedure generally takes between 30 to 60 minutes, depending on the number and size of the polyps and the complexity of the surgery.
Risks include bleeding, infection, recurrence of polyps, damage to surrounding structures, or a change in the sense of smell. However, these complications are rare, and the procedure is generally considered safe.
Preparation involves a preoperative consultation, possible imaging (like a CT scan) to assess the sinuses, and avoiding blood-thinning medications for a few days before surgery. You may also need to fast for several hours before the procedure.
Most patients can return to normal activities within 1 to 2 weeks. Full recovery may take a few weeks, and follow-up visits are necessary to monitor healing and ensure the polyps do not return.
While surgery can effectively remove the polyps, they can return in some cases, particularly if the underlying inflammation (e.g., chronic sinusitis, allergies) is not controlled. Post-surgery treatments like nasal corticosteroid sprays and saline irrigation can help reduce the risk of recurrence.
To reduce the likelihood of recurrence, follow your doctor’s advice, which may include using nasal corticosteroids, managing allergies, avoiding irritants like smoke or pollutants, and keeping your sinuses clear with saline irrigation.
