Symptoms and Treatment Methods of Turbinate Hypertrophy
Turbinate hypertrophy, clinically, is mainly hypertrophy of the inferior turbinate, although the middle turbinate can also become enlarged. The hypertrophy of the middle turbinate is primarily related to the development of the turbinate itself. Hypertrophy of the inferior turbinate is more common in clinical practice. Its symptoms mainly manifest as nasal congestion, as the enlarged turbinate blocks the nasal passages. Secondly, turbinate hypertrophy can sometimes irritate the nerves of the local septal mucosal tissue, causing headaches and subsequent symptoms like sinusitis. Clinical treatment for turbinate hypertrophy primarily involves medication, including the use of nasal spray drugs and traditional Chinese medicine. A sinus CT scan can be conducted to evaluate the extent of turbinate bone hypertrophy. If there is bony hypertrophy of the turbinate, surgery under endoscopy might be considered.
Do you need to check for allergens for allergic rhinitis?
Allergic rhinitis is a type of hypersensitivity disease. The first thing we need to know about allergic rhinitis is that it requires allergen testing. Traditionally, the diagnosis of allergic rhinitis is based on clinical symptoms, without involving etiological diagnosis. Testing for allergens is aimed at diagnosing based on its etiology. Secondly, we need to be aware of the allergens responsible for allergic rhinitis, which include food allergies and asthma-related allergies. By identifying food allergens, we can avoid consuming these substances in daily life. For instance, if one is allergic to fish and seafood, they should avoid eating these foods. Similarly, if allergic to mangoes, one should also avoid mangoes. Thus, overall, it is necessary to identify the sources of allergens in allergic rhinitis.
Does pharyngitis spread?
Pharyngitis refers to the acute and chronic inflammation of the pharyngeal mucosa, submucosal tissue, and local lymphatic tissue. Clinically, it mainly presents as a sore throat or a foreign body sensation in the throat, among other discomforts. Acute pharyngitis should be noted for its certain contagiousness, primarily due to viral infections, bacterial infections, or a combination of both, thus it is contagious. Appropriate precautions such as isolation measures, like wearing masks, should be considered. As for chronic pharyngitis, it is not contagious, so special isolation measures are not necessary. Regarding pharyngitis accompanying other diseases, such as reflux pharyngitis which may also involve Helicobacter pylori infection of the stomach, some literature reports suggest that Helicobacter pylori can be contagious during chronic pharyngitis, but this has not been fully confirmed and is only based on some reports. In summary, acute pharyngitis is confirmed to be contagious, while chronic pharyngitis is currently not contagious.
Is sinusitis the same as rhinitis?
There are differences between rhinitis and sinusitis. Rhinitis is mainly the inflammation of the nasal mucosa, while sinusitis is the inflammation of the sinus cavity mucosa. The main clinical symptoms of rhinitis are nasal congestion and a runny nose. This runny nose is mostly mucous or watery, which is typically seen in allergic rhinitis. The runny nose in sinusitis, on the other hand, is often a thick yellow discharge caused by a bacterial infection, so there is a distinction between the two. Patients with sinusitis often have rhinitis, but those with rhinitis do not necessarily have sinusitis. Rhinitis is primarily treated with medications and rarely with surgery. For sinusitis, treatment also begins with medications; however, if the response to medical therapy is poor or the condition is severe, surgery is often considered. The likelihood of undergoing surgical intervention is generally higher for sinusitis than for rhinitis.
Can rhinitis cause coughing?
Rhinitis refers to the inflammation of the nasal mucous membrane, which can cause coughing. The rhinitis-induced cough primarily involves two aspects. One is allergic rhinitis, which can lead to allergic pharyngitis, resulting in symptoms of coughing. According to the medical approach to allergic pathophysiological reactions, this is considered 'one airway, one disease,' where the allergic condition starts from the nose and develops into an allergy in the throat. Another situation involves the abundant secretions in rhinitis. These secretions flow back to the nasopharyngeal area and then irritate the throat, which can cause coughing. Therefore, overall, rhinitis can lead to coughing, and it should be managed and treated according to its different causes.
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.
