Is there a high possibility that nasal polyps are malignant?
Nasal polyps are a type of benign neoplasm in the nasal cavity, appearing as half a lychee, translucent, and either oval or ovoid in shape. They occupy the normal passages of the nasal cavity, causing symptoms such as nasal congestion, and even headaches in the head or forehead area. Nasal polyps are benign neoplasms and rarely develop into malignant lesions. Clinically, there have been no cases seen where nasal polyps have turned malignant. Some growths that look like nasal polyps may actually be nasal papillomas, which are more prone to malignancy. Therefore, it is recommended that patients with nasal polyps undergo early surgical intervention followed by a pathological examination to differentiate them from nasal papillomas and to assess the prognosis of the condition.
Yellow nasal discharge is what kind of cold?
Yellow nasal discharge is not a symptom of a cold. A cold, also known as an upper respiratory tract infection, typically presents with clear nasal discharge, indicating a viral infection. The appearance of yellow nasal discharge could suggest two possibilities: it could either be a symptom of sinusitis or it could indicate a secondary bacterial infection following a cold, especially in the later stages of a cold, manifesting symptoms similar to sinusitis. Therefore, yellow or yellow-purulent nasal discharge is definitively not a cold; it might be a symptom of sinusitis occurring late in the course of a cold or as the cold is resolving. In conclusion, yellow nasal discharge is not indicative of a cold.
Which is more serious, chronic rhinitis or allergic rhinitis?
Chronic rhinitis primarily involves inflammation of the nasal mucosa, submucosal tissues, nasal conchae, tympanic membrane, and even the bones. Allergic disease mainly involves allergic inflammation of the nasal mucosa. There is no clear distinction in severity between chronic rhinitis and allergic rhinitis. If chronic rhinitis tends towards an atrophic progression, then it is relatively serious. Allergic rhinitis, with its recurrent episodes, causes allergic cough and allergic asthma, which also signifies a relatively serious condition. Therefore, both chronic rhinitis and allergic rhinitis require active treatment, rather than distinguishing which one is more severe or which condition is milder. All issues should be actively treated.
What to eat after vocal cord polyp surgery
Vocal cord polyps are benign neoplasms located on the vocal cords, typically affecting one side. Clinically, the removal of vocal cord polyps is usually done under a microscope-supported laryngoscopy. Post-operative dietary guidelines include: 1. Eating can generally resume six hours after anesthesia has fully worn off, with a requirement for a bland diet. Consuming spicy and stimulating foods, such as tobacco, alcohol, and chili peppers, must be avoided. 2. Since hospital stays for vocal cord polyp surgery are relatively short, after discharge, one can use proprietary Chinese medicines that clear the throat and benefit the voice, or use corticosteroid medications concurrently. These medications can help prevent the recurrence of vocal cord polyps and reduce post-operative congestion and swelling of the vocal cord mucosa. 3. After surgery, a normal diet can be resumed, so long as it remains bland. However, care should be taken sometimes to avoid foods like fish, shrimp, and other seafood, which can cause allergies, as well as certain fruits like mangoes. It is advisable to minimize consumption of allergy-prone foods.
Can people with vocal cord nodules drink alcohol?
Vocal cord nodules are benign neoplasms located on the vocal cords, usually occurring bilaterally and symmetrically. The main clinical symptom is hoarseness. Individuals with vocal cord nodules should avoid alcohol, as drinking can cause the vocal cord mucosa to become congested and swollen, exacerbating vocal cord nodules or chronic inflammation, and worsening the condition. Additionally, alcohol can directly irritate the vocal cords because it is a spicy and irritating substance. Therefore, it is advised not to drink alcohol when you have vocal cord nodules. It is also important to avoid abusing the voice, which includes refraining from long periods of speaking and not screaming loudly. These precautions need to be adhered to.
Can you smoke with acute pharyngitis?
Acute pharyngitis is an acute inflammatory disease of the pharyngeal mucosa, submucosal tissue, and local lymphatic tissue. Initially, it is a viral infection or a mixed infection of viruses and bacteria; in later stages, when secondary infections occur, it may entirely turn into a bacterial infection. During acute pharyngitis, there is pain in the pharyngeal region, and the pharyngeal mucosa becomes congested and swollen. We must advise patients not to smoke as it further irritates and exacerbates the congestion and swelling of the pharyngeal mucosa, worsening the condition of acute pharyngitis. Smoking can even cause the infection in the pharynx to spread to the lower airways, leading to tracheitis, bronchitis, and pneumonia; therefore, smoking should be avoided during acute pharyngitis.
What should I do if otitis media causes a fever?
Otitis media is an acute infectious inflammation of the ear, which can also be chronic. Fever indicates that the otitis media is an acute inflammation, and the presence of fever, indicating an increase in body temperature, suggests that the inflammation is relatively intense and severe. Therefore, it is mainly necessary to provide enhanced anti-infection treatment. Otitis media is primarily a bacterial infection, so the main treatment is the use of cephalosporin antibiotics. Generally, when there is a fever, blood can be drawn to check a complete blood count to see the level of white blood cells, indicating the degree of infection. Clinically, infusion anti-infection treatment is generally provided, mainly using cephalosporin antibiotics. If the pain is significant and the temperature is high, corticosteroids can also be used for combined treatment.
Treatment methods for adenoid hypertrophy
Adenoid hypertrophy refers to the hyperplasia and enlargement of the adenoid tissue in the nasopharynx, blocking the local upper airway passages, leading to conditions such as rhinitis, sinusitis, otitis media, and snoring during sleep. Clinically, there are two treatment methods: conservative medication and surgery. Currently, there are no specific drugs aimed at adenoid hypertrophy. Typically, treatments involve the use of nasal corticosteroids such as mometasone furoate nasal spray and anti-allergic medications like montelukast. However, the effectiveness of the treatment may vary from person to person or be unpredictable. Generally, medication is first tried for one to three months, or depending on the severity of the adenoid hypertrophy, treatment can last about two weeks to four weeks. If the medication is not effective, or shows no results, surgical intervention to remove the enlarged adenoids and facilitate airway clearance is necessary. (Please use medication under the guidance of a clinical doctor and do not self-medicate.)
Can vocal cord polyps cause loss of voice?
Vocal cord polyps are benign neoplasms that occur on the vocal cords. They protrude from the surface of the vocal cords. Generally, after the occurrence of vocal cord polyps, surgical treatment is performed to remove them, as vocal cord polyps can cause hoarseness, affecting our work, and impacting our career and life. Severe vocal cord polyps, if not treated, can lead to repeated friction between the vocal cords, which may even result in the potential malignancy. Of course, vocal cord polyps severely affect our voice quality, causing hoarseness and in severe cases lead to voice loss, causing a sensation of air leakage when we speak. In summary, vocal cord polyps can lead to loss of voice.
Is surgery necessary for suppurative tonsillitis?
Purulent tonsillitis refers to the acute purulent inflammation of the tonsils, mainly caused by bacterial infection, including infections by Streptococcus pyogenes, Staphylococcus aureus, etc. Purulent tonsillitis is an acute inflammation, so during this acute inflammation phase, the primary treatment is the use of antibiotics for anti-infection. After the anti-infection treatment, the symptoms of the patient disappear, and then it can be assessed whether surgical treatment is needed. Generally speaking, sporadic occurrences of purulent tonsillitis do not require surgical treatment. For frequently recurring purulent tonsillitis and enlarged tonsils, surgical treatment should be considered after the acute inflammation has subsided.
