What is throat cancer diagnosed through?
Laryngeal cancer is a relatively common disease in otolaryngology. It is divided into several types, such as glottic cancer, supraglottic cancer, subglottic cancer, and transglottic cancer. The clinical diagnosis of laryngeal cancer first requires a medical history, such as a long-term history of smoking and viral infections. Clinically, patients may present with chronic hoarseness and physical examinations can reveal tumorous tissue growth. Additional diagnostic tools include the use of a laryngoscope, as well as CT or MRI imaging studies. The most crucial standard for definitive diagnosis is the examination of pathological tissues, specifically biopsy. During the clinical diagnostic process, it is also necessary to differentiate between laryngeal cancer and conditions that may present similarly, such as laryngeal papillomatosis, to definitively diagnose laryngeal cancer. This outlines the clinical diagnostic procedure for laryngeal cancer.
What is the method for examining sinusitis?
Sinusitis refers to the inflammation that occurs in the mucous membrane or cavity of the sinuses. Clinically, the examination of sinusitis includes two aspects: one is the clinical examination, such as anterior rhinoscopy to inspect the nasal cavity, nasal endoscopy to inspect the nasal cavity, the opening of the sinuses, and the nasal passages; on the other hand, some imaging examinations can also be used, such as sinus CT examination, which is very important, and if necessary, sinus MRI can also be performed; there are also some other examination methods, such as nasal resistance examination, examination of sinus and nasal secretions, etc. Therefore, there are quite a few examination methods, among all the examination methods, the most important are the nasal endoscopy and sinus CT examination.
What department should I visit for pharyngitis?
Pharyngitis is a common and frequent disease in otolaryngology head and neck surgery, so it is primarily necessary to visit the department of otolaryngology head and neck surgery for diagnosis and treatment. In hospitals with more specialized departments, one can also directly visit the pharyngology department for diagnosis and treatment. It is important to understand that there are many causes of pharyngitis, such as gastroesophageal reflux disease. Besides seeing an otolaryngologist, it might also be necessary to consult with gastroenterology or thoracic surgery, as these are related departments. If the pharyngitis is caused by an allergic disease and involves allergic factors, in addition to visiting otolaryngology, it may be necessary to consult other departments such as the department of allergic diseases or respiratory medicine, depending on the specific circumstances. In summary, the primary department to consult for pharyngitis is otolaryngology head and neck surgery.
Do vocal cord nodules hurt?
Vocal cord nodules are symmetric, benign protrusions that occur on the free edge of the vocal cords. Clinically, the main symptoms of vocal cord nodules include a hoarse voice and fatigue after prolonged speaking, typically without any sensation of pain or causing any pain. Treatment primarily involves medication, voice therapy, and for some vocal cord nodules that appear after an acute upper respiratory infection, hormonal treatment may be required, or combined with some antibiotics. In summary, vocal cord nodules do not cause painful symptoms, and treatment focuses mainly on voice training and rest for the vocal cords.
What are the symptoms of a deviated nasal septum?
Nasal septum deviation refers to the condition where the cartilaginous and bony tissue of the nasal septum leans to one side, affecting one or both nasal cavities. Clinically, it primarily presents as nasal congestion. This congestion is unilateral and persistent, or it can be persistent on both sides. Additionally, nosebleeds occur because the mucous membrane on the deviated side is very thin, making it susceptible to bleeding due to friction from the airflow during breathing. Furthermore, the deviated nasal septum can irritate the turbinates, leading to nerve reflex pain and resulting in headaches. Thus, the main symptoms of nasal septum deviation include the ones listed above.
What is good to eat usually for Ménière's disease?
Ménière's disease is a common inner ear disorder that causes vertigo. Clinically, it is divided into two periods: an acute attack period and a quiescent period. Regarding the diet for Ménière's disease, first and foremost, the diet should be light, similar to fish, shrimp, seafood, while it is best to minimize or avoid consumption of alcohol, spicy foods such as chili peppers. Secondly, it is important to be aware of other items such as coffee and tea, which are stimulants and should ideally be avoided as they can affect the sleep patterns of patients with Ménière's disease. Thirdly, as previously mentioned, foods that are common allergens like fish, shrimp, and seafood should also be consumed in moderation.
Distinction between Nasopharyngitis and Nasopharyngeal Carcinoma
Nasopharyngitis and nasopharyngeal carcinoma have fundamental differences. Nasopharyngitis is an inflammatory disease, while nasopharyngeal carcinoma is a malignant tumor disease. Clinically, nasopharyngitis mainly presents with increased secretions in the nasopharyngeal area, sometimes with a slight amount of bloody secretions, but this is extremely rare. On the other hand, nasopharyngeal carcinoma primarily shows symptoms such as the proliferation of malignant tumor tissues in the nasopharynx, enlargement of the lymph nodes in the neck, headaches, and ear stuffiness. In terms of treatment, nasopharyngitis is primarily treated with medications, such as traditional Chinese medicines, nasal sprays, and nasal corticosteroids; whereas nasopharyngeal carcinoma is primarily treated with radiotherapy combined with chemotherapy, which is currently the common sandwich therapy. Overall, there are fundamental differences between the two.
Do vocal cord polyps hurt?
Vocal cord polyps are benign, space-occupying lesions that occur on the free edge of our vocal cords. After the occurrence of vocal cord polyps, the main symptom is hoarseness of voice. In severe cases, there may be loss of voice, and if the vocal cord polyps are large, it may cause a sensation of air leaking when speaking. Generally, vocal cord polyps do not cause pain unless there is concurrent acute pharyngitis, which then results in pain in the throat area. This pain is mainly due to the acute pharyngitis. During surgery for vocal cord polyps, anesthesia is typically used, so there is no pain during the procedure. The surgery is usually performed under a microscope, and there is no significant pain in the throat area after the surgery. In conclusion, vocal cord polyps do not cause pain.
Can otitis media cause a fever?
Otitis media is a common and frequent disease in the otolaryngology department, mainly involving the head and neck domains. It primarily arises from bacterial infections leading to both acute and chronic forms of otitis media. While chronic otitis media typically shows no apparent symptoms, acute otitis media often manifests clinically with symptoms such as ear pain, tinnitus, hearing loss, and in severe cases, ear discharge. If the symptoms are severe, the patient may also experience systemic symptoms like fever, chills, general discomfort, and reduced appetite. Thus, fever can indeed be a symptom of otitis media, largely related to the extent of the inflammatory infection. If the inflammation is due to a specific bacterial infection, the symptoms may be relatively more severe. Additionally, if the inflammation spreads to adjacent structures, such as cranial structures, the fever may be more pronounced.
Can people with vocal cord polyps drink alcohol?
Vocal cord polyps are benign neoplasms that occur on the free edge of our vocal cords. People with vocal cord polyps should not drink alcohol for several main reasons: Firstly, alcohol directly irritates the vocal cords, which is a stimulatory effect. Secondly, after drinking alcohol, blood vessels dilate. The dilation of blood vessels in the vocal cord mucosa leads to vocal cord congestion and aggravated vocal cord edema, which further exacerbates inflammation. Thirdly, some patients may be allergic to alcohol. An allergic reaction can also cause congestion and increased edema of the vocal cord mucosa, worsening the condition of vocal cord polyps. Therefore, considering the aforementioned reasons, patients with vocal cord polyps cannot drink alcohol.
