Nasal polyps must first undergo a biopsy before surgical treatment can proceed. A clear diagnosis is necessary. If it is a nasal polyp, local surgical removal is needed. If it is a bleeding or malignant nasal polyp, local hemostasis, radiotherapy, or chemotherapy is required. Nasal polyps can occur for various reasons clinically, and are generally directly related to chronic rhinitis or chronic allergic rhinitis in patients. They are polyps formed from the diffuse congestion, edema, and prolapse of the nasal concha mucosa due to long-term inflammatory stimulation. Nasal polyps can lead to persistent nasal congestion in both nasal cavities, along with a sense of swelling and foreign body sensation in the nasal cavity. In severe cases, it can cause a decrease in the sense of smell and memory. It is necessary to go to the hospital for a detailed examination. An electronic nasal endoscope and sinus CT can determine if there are any abnormal tumors. If a tumor is found, a local biopsy will be required. If it is confirmed as a nasal polyp, local surgical removal is necessary for treatment.

What medicine is effective for nasal polyps?

The treatment of nasal polyps currently mainly includes two types: conservative treatment and surgical treatment. For smaller, localized nasal polyps with relatively mild clinical symptoms, conservative drug treatment is primarily considered. Currently, corticosteroid nasal sprays are predominantly used, mainly to improve nasal ventilation, reduce mucosal edema, and shrink the nasal polyps. Some patients may even see the polyps disappear completely. However, there are also patients who do not respond well to this treatment, or have relatively large polyps. In these cases, conservative treatment may be less effective, and surgery might be considered. Presently, minimally invasive surgery under endoscopic guidance is commonly performed to remove nasal polyps, and generally, the outcomes are quite definite. (Answer for reference only, medications should be taken under the guidance of a professional physician and not self-administered.)

Does nasal polyps require a biopsy?

Nasal polyps are benign space-occupying lesions in our nasal cavity and sinus cavity. They primarily appear as a pineapple peel-like or half a lychee-like neoplasm. They lack blood vessels and nerves, so nasal polyps generally do not undergo biopsy unless there is suspicion of malignant transformation, in which case a biopsy is performed. Typically, nasal polyps are treated surgically by removing them during surgery, then the excised tissue is sent for pathological examination to determine if the polyps are benign or malignant. Therefore, generally speaking, nasal polyps do not undergo biopsy.

How is nasal polyps treated?

Nasal polyps are a common clinical condition, prevalent in the nasal and sinus cavities as benign space-occupying lesions. Clinically, these polyps appear as translucent, lychee-like neoplasms. The primary clinical treatment for nasal polyps is surgical, typically performed with an endoscope to remove the polyps, mainly using a powered system. After nasal polyp surgery, the treatment is not completely finished; regular outpatient follow-ups are necessary to infiltrate the nasal and sinus cavities and remove some of the swollen mucosal tissue, thus preventing the recurrence of nasal polyps.

Can nasal polyps be seen on an X-ray?

Nasal polyps are a relatively common otolaryngology disease, which can be comprehensively assessed through nasal endoscopy or sinus CT scan. Generally speaking, nasal endoscopy is more intuitive, allowing direct observation of the extent and severity of polyps within the nasal cavity. If a sinus CT scan is performed, it has diagnostic and reference value for multiple nasal polyps, but it might not be very clear if there are only a few polyps. In terms of treatment, if there are numerous nasal polyps and medication is ineffective, surgical treatment should be considered. If the nasal polyps are limited and the clinical symptoms are mild, medical conservative treatment is recommended, but regular follow-up examinations are necessary to monitor the effect. (Specific medications should be used under the guidance of a doctor.)

How to check for nasal polyps

Nasal polyps are benign space-occupying lesions that occur in the nasal cavity and sinus cavities. There are several aspects to the examination of nasal polyps: Firstly, an anterior rhinoscopy examination can be performed. If the nasal polyps are large, or even protruding outside the nasal cavity, they can be directly seen. Anterior rhinoscopy enlarges the nasal cavity, allowing visualization of the middle nasal meatus and other tissues inside the nasal cavity. Secondly, a nasal endoscopy can be utilized. Nasal endoscopy is particularly effective for viewing polyps located deeper within, or at the back of the nasal passages, providing very clear visibility. Other examinations, such as electronic rhinoendoscopy, follow the same procedure. The third examination involves a sinus CT scan, which is helpful for identifying the origin of the nasal polyps, as well as the location, range, and extent of obstruction caused by the polyps. Another examination is the pathological examination after nasal polyp surgery, which aids in determining the origin and risk associated with the nasal polyps, as well as assisting in subsequent treatments.
