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.
Indications for stopping medication for suppurative tonsillitis
Purulent tonsillitis is an acute bacterial infection in the throat characterized by purulent lesions. Clinical examination reveals congested and enlarged tonsils with greyish-white or white pseudomembranous inflammatory secretions covering the surface of the tonsils or the area of the throat. Active anti-infection treatment is necessary for purulent tonsillitis. The criteria for discontinuing medication include the disappearance of clinical symptoms, such as the absence of sore throat; reduction of tonsil congestion, and reduction or disappearance of the pseudomembrane on the tonsil surface. Additionally, other factors should be considered, such as the results of a complete blood count, with white blood cell levels returning to normal reference ranges. Further considerations include complications such as concurrent arthritis or glomerulonephritis. If clinical examinations or signs suggest these are resolved, cessation of medication for purulent tonsillitis may be considered, typically continuing the process for about one to two weeks. (Please use medication under the guidance of a doctor)
Is laryngitis contagious?
Laryngitis is an acute inflammatory disease of the throat, especially the vocal cords. Clinically, it is mainly caused by bacterial infection or long-term excessive misuse of the voice. For bacterial infections or mixed infections of bacteria and viruses, this type of laryngitis has certain contagiousness, but the contagiousness is relatively weak and it is not a severe or highly contagious disease. Secondly, laryngitis caused by long-term misuse of the voice mainly results from mechanical damage and is non-contagious. Moreover, this type of laryngitis tends to be more chronic. In summary, acute laryngitis caused by bacterial and viral infections has certain contagiousness, but the contagiousness is very weak.
What cold is nasal congestion?
Nasal congestion is the most common clinical symptom of nasal diseases. Various disorders, such as rhinitis, sinusitis, nasal foreign bodies, and even nasal tumors can cause nasal congestion. In terms of colds, clinically it mainly refers to an upper respiratory infection caused by a viral infection. Therefore, nasal congestion alone cannot determine which type of cold it is. The types of colds, in modern medicine, refer to upper respiratory infections. In traditional Chinese medicine, they are divided into colds caused by wind-heat and colds caused by wind-cold. Merely from the symptom of nasal congestion, it is impossible to determine the type of cold. Therefore, in clinical practice, the main focus for treating nasal congestion is symptomatic treatment, which may include the use of medications to constrict the nasal blood vessels and clear the nasal passages. (Please follow the doctor's prescription for medication use.)
Can nasal polyps turn into nasal cancer?
Nasal polyps are benign neoplasms in the nasal cavity or sinus cavity, appearing as translucent, lychee-like formations without the distribution of nerves and blood vessels. Generally, nasal polyps cannot become cancerous unless they are long affected by other factors, such as possible concurrent conditions like papillomas or mucosal lesions, which could then transform into malignant tumors. However, the likelihood of nasal polyps directly transforming into malignant tumors is extremely rare, and such clinical cases are almost nonexistent. Therefore, from the perspective of pathology or clinical studies, the possibility of nasal polyps turning into nasal cancer is exceedingly small.
Is it safe to have a second surgery for nasal polyps?
The surgery for nasal polyps is primarily performed under general anesthesia, involving the removal of the nasal polyps and functional endoscopic sinus surgery. All surgeries carry certain risks, thus secondary surgeries for nasal polyps also entail risks. Moreover, since the initial surgery alters the normal anatomical structure of the nasal polyps and their surroundings, the difficulty of the surgery increases, thereby slightly raising the risk of a secondary procedure. The third point is that the surgery is now performed under direct endoscopic vision. Although this type of surgery carries risks—and indeed, all surgeries do—the likelihood of these risks is relatively small, so there is no need for excessive worry.
What should I do if nasal polyps recur for the second time?
Nasal polyps are a common and frequently occurring clinical disease, consisting of benign neoplasms in the nasal cavity and paranasal sinuses. Clinically, nasal polyps are primarily treated through surgery, specifically functional endoscopic sinus surgery for the removal of polyps under nasal endoscopy. Nasal polyps have a certain probability of recurrence. After a second recurrence, a second surgery is required. Following surgery, it is necessary to regularly follow up with cleaning of the nasal and sinus cavities, and to actively use certain medications, such as corticosteroids and some macrolide anti-inflammatory drugs. Additionally, during nasal polyp surgery, some tissues should be removed for biopsy to avoid confusion between nasal polyps and papillomas.
Do vocal cord polyps require a biopsy?
Vocal cord polyps are benign neoplasms located on the vocal cords, typically protruding from the surface or the free edge of the vocal cords. Therefore, the removal surgery for vocal cord polyps is generally performed under laryngoscopic and microscopic visualization. The procedure usually involves direct excision followed by pathological examination, and a biopsy is generally not conducted before the surgery. Thus, vocal cord polyps are typically treated through direct surgical removal without a pre-surgery biopsy. It is also important to avoid excessive misuse of the voice after the surgery to prevent recurrence of the vocal cord polyps.
What does it mean when nasal polyps bleed?
Nasal polyp bleeding mainly has three causes. One reason is that the nasal polyp damages the structure of the nose. Since nasal polyps are a space-occupying lesion, they gradually enlarge, compress the nasal structures, and damage the mucosa and blood vessels of the nose, which can lead to nasal bleeding. The second reason is that the nasal polyp itself may be a bleeding necrotic nasal polyp. This type of bleeding necrotic nasal polyp is very prone to bleeding, and even minor injuries or damage can lead to bleeding. The third reason is that bleeding necrotic nasal polyps might be a manifestation of the disease. As the nasal polyp enlarges, if such an enlarged polyp becomes lodged in a sinus opening or in the nasal cavity, it can lead to ischemic necrosis, which after occurring, can cause bleeding. In summary, these are the three main cases.
Does adenoid hypertrophy cause yellow nasal discharge?
The glands located in our nasopharyngeal area are immune tissues. Enlargement of these glands can lead to an increase in their size, which may block our posterior nasal apertures. Consequently, the secretions in our nasal cavity cannot be properly discharged. This may eventually lead to spontaneous infections causing sinusitis, characterized by the discharge of yellow nasal mucus. Thus, there is a direct relationship between the occurrence of sinusitis in children and the enlargement of these glands. Clinically, it can be observed that after surgery for gland enlargement, the symptoms of sinusitis and the discharge of yellow nasal mucus are significantly reduced or even completely cured. Therefore, it can be said that there is a direct relationship between gland enlargement and conditions such as rhinitis, sinusitis, and the discharge of yellow nasal mucus.
