Is surgery necessary for a deviated septum?
Nasal septal deviation refers to the situation where the cartilage and bone tissue of the nasal septum lean toward one side of the nasal cavity, representing a structural deviation. However, having just this deviation is insufficient for a complete diagnosis of a deviated septum. Symptoms such as nasal congestion, nosebleeds, and headaches must also be present to fully diagnose it. Treatment for a nasal septal deviation often involves surgical correction; however, surgery is not necessary for asymptomatic individuals with mere structural deviation. Surgery is opted for cases with structural deviation accompanied by symptoms like nasal congestion, nosebleeds, and headaches.
How is laryngeal cancer diagnosed?
In clinical settings, the diagnosis of laryngeal cancer primarily relies on several aspects. Firstly, the patient's history, such as a family history of laryngeal cancer, and whether there is a long-term smoking history, for example, smoking two packs a day. Secondly, we need some clinical data, such as whether the patient exhibits symptoms like hoarseness. Then, during physical examination, we need to check for the presence of cancerous tissues in the hypopharynx, vocal cords, and the subglottic cavity, such as the presence of lumps, uneven surfaces, erosion, ulcers, etc. These are its symptoms and signs. Furthermore, we can utilize some auxiliary examinations, such as laryngoscopy, which allows direct observation of the tumor tissue. However, the definitive test involves taking a sample of the tumor tissue for a biopsy, identifying the presence of tumor cells, i.e., cancer cells. This result serves as the basis for confirming a diagnosis of laryngeal cancer. Of course, other auxiliary examinations like CT scans and MRI can also assist in diagnosing laryngeal cancer.
What medication to spray for nasal polyps
Nasal polyps refer to benign space-occupying lesions in our nasal cavities. Clinically, nasal polyps are mainly associated with allergies or increased vascular and tissue permeability. Other factors, such as abnormalities in the structure of the middle nasal meatus, are also related to their formation. Therefore, in terms of treatment, clinically, we mainly use some steroids, mainly spraying corticosteroid hormones, such as mometasone furoate, budesonide nasal spray, fluticasone propionate nasal spray, etc. Additionally, if there is a significant amount of pus in the nasal discharge, we can also use saline nasal spray to clean the nasal cavity.
How is nasal polyp surgery performed?
Nasal polyps are benign neoplasms in our nasal cavities. Nasal polyps do not have a distribution of nerves and blood vessels. Once nasal polyps occur, the main treatment is surgical removal. The surgery is performed under general anesthesia. We expose the nasal polyps using an endoscope, and then remove the nasal polyps using forceps or an electric suction cutter. The surgical operation is relatively simple. However, it is important to protect the surrounding structures such as the eyes and brain during the surgery to avoid damaging these tissues. After surgery, it is common to pack the nasal cavity, and the entire procedure generally requires a hospital stay of about one week.
Nasopharyngeal carcinoma clinical manifestations
Nasopharyngeal carcinoma is the most common malignant tumor in the nasopharyngeal area, and clinically, it is primarily squamous cell carcinoma. The incidence of nasopharyngeal carcinoma is particularly high in the southern regions of China, especially in Guangdong. Initially, nasopharyngeal carcinoma manifests locally as a tumorous mass in the nasopharyngeal area, often with ulceration on the surface. This can lead to the presence of blood in nasal mucus, known as bloody nasal discharge. As the disease progresses, there can be swelling of the cervical lymph nodes, primarily involving the upper deep cervical lymph nodes, with about 60% of patients experiencing this type of lymph node enlargement. As the tumor enlarges, it may block the nasal passage, leading to persistent nasal congestion. The tumor's pressure on the Eustachian tube can cause symptoms of secretory otitis media. Furthermore, damage to the skull base by the tumor can lead to severe headaches. As a malignant tumor, the cancer can cause systemic symptoms such as malnutrition and cachexia. In advanced stages, metastatic symptoms may appear, such as bone and liver metastases, affecting these vital organs.
Is allergic rhinitis contagious?
Allergic rhinitis is a type of hypersensitivity reaction occurring in our nasal cavity. It is an immunological disease, not caused by bacterial or viral infections, so it is definitely not contagious. However, in real life, it may create an appearance of being contagious. For example, if one family member develops allergic rhinitis, other family members might also start showing symptoms of allergic rhinitis. This is mainly because all family members live in the same environment, which might be the allergen-triggering environment. Essentially, allergic rhinitis is a hypersensitivity disease and is not contagious. It’s just that living in the same environment, everyone may develop this disease, but it is not transmitted from one person to another.
The difference between acute pharyngitis and chronic pharyngitis
Acute pharyngitis and chronic pharyngitis have fundamental differences, primarily in the nature of the diseases. Acute pharyngitis is acute, while chronic pharyngitis is chronic. Due to the different nature of the diseases, the clinical symptoms of acute and chronic pharyngitis also differ. Acute pharyngitis typically presents clinically with throat pain, whereas chronic pharyngitis usually manifests as dryness, itchiness in the throat, or a sensation of a foreign body in the throat, among other discomforts. Additionally, their treatments are different. For acute pharyngitis, antibiotics may be used if there is purulent sputum or a bacterial infection. In contrast, chronic pharyngitis generally does not involve the use of antibiotics; instead, treatment mainly consists of taking Chinese patent medicines that clear heat and detoxify the body. Thus, the differences between them are quite distinct. (Please consult a professional physician before using any medication; do not self-medicate.)
Can a deviated nasal septum cause nosebleeds?
Deviated nasal septum refers to the fracture of the cartilage of the nasal septum, deviating toward one or both nasal cavities. Patients with a deviated nasal septum are prone to bleeding, and this bleeding tends to recur. This is because after the cartilage of the nasal septum deviates toward one side of the nasal cavity, continuous breathing causes the airflow to rub against the protruding nasal mucosal tissue of the deviated side. Additionally, after the deviation, the nasal mucosal tissue itself becomes thinner. Under these conditions, the thinner mucosal tissue at the deviated part is more likely to rupture and get damaged, making it prone to erosion and bleeding, and the blood vessels are also more likely to rupture, leading to bleeding. In summary, a deviated nasal septum can lead to nosebleeds.
What ear drops are used for otitis media?
Otitis media primarily refers to the acute and chronic inflammation of our middle ear tympanic membrane, tympanic cavity, and mastoid cavity. Clinically, when ear drops are needed for treatment, it mainly refers to acute otitis media, which is primarily caused by bacterial infection, such as Staphylococcus aureus, Streptococcus pneumoniae, etc., caused by bacterial infection. Therefore, the ear drops mainly used are antibiotic eye drops, such as ofloxacin eye drops, lomefloxacin eye drops, compound polymyxin B ear drops, penicillin, hydrocortisone eye drops, etc. It is important to note that some special ear drops, such as phenol ear drops, can be used when the patient is not in pain. However, if the patient has a tympanic membrane perforation, then phenol ear drops should not be used, as they have the effect of burning the mucous membrane of the middle ear, so they cannot be used. (Note: The above medications should be used under the guidance of a doctor.)
How to maintain throat health in daily life?
Pharyngitis primarily refers to the acute or chronic inflammation of the mucous membrane in our throat. For the care of pharyngitis, we should pay attention to the following points: First, we need to be mindful of our diet, which should be light, nutritious, and easy to digest. We must avoid spicy and irritating foods, such as cigarettes, alcohol, and chili peppers. Second, we should engage in appropriate physical exercise to strengthen our constitution and avoid frequent upper respiratory infections. These conditions can prevent our pharyngitis from being effectively treated, or even cured. Thirdly, we should be cautious with certain special foods. For example, if our pharyngitis is caused by allergies, then we should minimize or avoid foods that can trigger allergies, such as fish, shrimp, and seafood. In conclusion, it is crucial to actively treat pharyngitis while also looking after oneself.
