Nasal polyps are growths in the nasal cavity mucosa that form due to inflammation, edema, and the effects of gravity, resembling lychee-like neoplasms. They are relatively soft and do not bleed easily upon formation. Their stalk mainly originates from the middle nasal meatus, making nasal polyps a benign tissue lesion that will not become cancerous. However, prolonged growth of polyps may lead to deformation of the nasal cavity, obstructing ventilation and drainage, which can cause sinusitis, nasal congestion, headaches, and more. Therefore, early-stage nasal polyps can be conservatively treated with internal medicine. If there is nasal obstruction, aggressive growth, or purulent nasal discharge, surgical treatment is generally recommended to prevent recurrence.

Are nasal polyps serious?

Nasal polyps are a relatively common otolaryngologic disease, and for the most part, most patients are not too serious; only a small number of patients have more severe nasal polyps with more obvious symptoms. In terms of treatment, if the nasal polyps are few and the clinical symptoms are not particularly pronounced, conservative medical treatment can be considered. Commonly used are corticosteroid nasal sprays, and physiological saline can be used to rinse the nasal cavity to help improve clinical symptoms; if there are many nasal polyps and the clinical symptoms are very pronounced, and standard medication treatment is ineffective, surgery may be considered. A common procedure is endoscopic nasal polyp removal. (Medication should be used under the guidance of a doctor according to specific circumstances.)

Is minimally invasive surgery for nasal polyps painful?

We often talk about the minimally invasive surgery for nasal polyps, which is the most common procedure of endoscopic nasal polyp removal that we use today. This type of surgery does not only remove the nasal polyps, but also the root of the polyps and even opens up the sinuses. This is crucial for eliminating the cause of the nasal polyps and is very important for preventing their recurrence. Although it is a minimally invasive surgery, it can still be quite painful. After the surgery, both nostrils need to be packed. If the packing material is absorbable, such as Nasopore, the discomfort might be less because after the surgery, one just needs to wait for the packing to gradually dissolve into a mucus-like substance and get expelled. However, if expandable sponges or even gauze strips are used, these materials need to be removed after several days. Removing these materials can cause significant pain for the patient. During the period of packing, the patient can also experience a lot of discomforts such as headaches, dry throat, discomfort in the eyes, tearing, and even some might feel foggy in their ears and uncomfortable while eating and drinking, along with other painful symptoms. Additionally, after the minimally invasive surgery for nasal polyps, regular follow-up cleanings are necessary. The purpose of these follow-up cleanings is to timely clear out any blood clots or secretions from the nasal cavity and sinuses, aiding the recovery of the mucous membranes in these areas and also preventing the short-term recurrence of the nasal polyps, which is a very important part of ensuring the effectiveness of the surgery. Thus, these procedures can induce a certain amount of fear and pain for the patients, but before performing these surgeries and examinations, doctors generally engage in thorough discussions and provide comfort to the patients, advising them not to be too nervous. The actual discomfort is temporary and will pass after enduring it for just a few days post-surgery.

Can nasal polyps be felt by touch?

Nasal polyps are benign neoplasms that occur in our nasal cavity. Clinically, nasal polyps in their early stages are primarily located in the middle nasal passage. As the nasal polyps enlarge, they can also be found in the middle nasal passage, and severe ones might even protrude from our anterior nostrils onto our face. Thus, for larger nasal polyps, we can physically feel them; they feel very soft and not very elastic. However, they are somewhat resilient and can move significantly because most nasal polyps are pedunculated within our nasal cavity. Additionally, there is often a lot of nasal mucus.

The causes of nasal polyps formation

Nasal polyps are a relatively common ENT (Ear, Nose, and Throat) disorder, with various causes. Common causes include genetic factors and may also be due to chronic allergic rhinitis or sinusitis. Some patients develop nasal polyps because of frequent exposure to dust or other chemical substances. There are significant individual differences in the specific causes of the disease. After the onset of the disease, it is necessary to visit an ENT specialist. Procedures like a nasal endoscopy or a sinus CT scan can be performed to assess the severity of the condition, which will assist in determining targeted treatments. During the treatment process, regular check-ups are needed to observe the recovery progress of the condition.

What are the symptoms of nasal polyps?

Nasal polyps are benign tumors that occur inside the nasal cavity. Generally, the appearance of nasal polyps is associated with chronic inflammatory stimulation, repeated irritation of the turbinate mucosa leading to congestion, edema, prolapse, and hyperplasia of the turbinate mucosa, which causes nasal polyps. They are also often secondary to allergic rhinitis. Nasal polyps can cause bilateral nasal congestion in patients, which tends to persist and worsen, while mucous secretions may also flow from the nasal cavity. In severe cases, patients may experience facial swelling, pain, headaches, and other related symptoms. During examination, pale white lychee-like, soft new growths that are usually painless can be found inside the nasal cavity. In terms of treatment, nasal polyps require endoscopic nasal polypectomy. The surgery requires hospitalization, general anesthesia, and postoperative antibiotics to prevent local infection. Patients can usually recover and be discharged about a week after the surgery. (The use of medications should be under the guidance of a professional doctor.)
