Causes of Chronic Rhinitis
The causes of chronic rhinitis are quite complex and not due to a single factor. It often arises from multiple factors after prolonged and repeated acute attacks, leading to chronic inflammatory changes. These changes primarily affect the nasal mucosa, with the most common causes including: First, prolonged and repeated bouts of acute rhinitis that are not thoroughly treated can lead to chronic rhinitis. This also includes some chronic diseases of the nasal cavity and sinuses, such as congenital deviation of the nasal septum, meaning the middle part of the nose is crooked, which disrupts drainage and airflow in the nasal cavity. Thus, when there is an acute inflammation, the secretions cannot be drained timely, eventually causing chronic inflammation of the nasal mucosa. Second, inflammation of nearby tissues and organs can lead to chronic rhinitis, such as chronic tonsillitis and adenoid hyperplasia during childhood. These chronic inflammations can cause secretions in the nasopharyngeal area to irritate and contribute to the chronic inflammation of the nasal mucous membrane, impacting each other. Third, occupational and environmental factors play a role. The living and working environment, along with lifestyle habits, greatly influence the incidence of chronic rhinitis. People who frequently smoke or drink alcohol are more susceptible to this condition. Additionally, if the work or living environment is polluted, dirty, dusty, or exposed to other harmful gases or chemicals, it may also lead to chronic rhinitis. Therefore, the formation of chronic rhinitis involves multifaceted and multiple causes, and the specific reasons should be analyzed based on different patients.
How is acute pharyngitis treated?
The treatment of acute pharyngitis is based on its causes and symptoms. First, it is recommended to gargle with mouthwash, which helps alleviate some throat symptoms. Additionally, it is important to rest, drink plenty of fluids, consume a liquid diet, and avoid foods that are too hot or too harsh to reduce irritation to the throat. Also, minimize speaking to allow the vocal cords to rest thoroughly, which can help alleviate symptoms of hoarseness. In terms of medication, the treatment primarily involves anti-inflammatory and antiviral therapies. Doctors will select the appropriate medication based on your drug sensitivity, routine medication experience, and the seasonal characteristics of the outbreak. Nebulized inhalation treatment is also necessary, which can relieve swelling of the throat mucosa, reduce mucosal swelling, and has an anti-inflammatory effect. If the condition is severe, systemic antibiotics and corticosteroids may be added, and traditional Chinese medicine lozenges can be used to support symptomatic treatment.
How to treat acute pharyngitis symptoms?
The treatment of acute pharyngitis symptoms primarily involves topical medication, systemic medication, and general measures. First, topical treatments mainly include traditional Chinese medicine lozenges, or medications delivered by nebulization, or various mouthwashes, etc. These topical medications mainly provide quick relief from symptoms such as dry throat, sore throat, and throat heat. As for systemic medications, these generally involve the use of antibiotics or antiviral drugs. Doctors will choose different treatments based on their assessment of the condition and what factors they believe have caused the acute pharyngitis. General measures include bed rest, drinking plenty of water, consuming easily digestible food, and avoiding spicy, irritating foods as well as environments with tobacco and alcohol.
How to treat vocal cord nodules?
The main symptom of vocal cord nodules is a hoarse voice, and some people often experience coughing. The cause of vocal cord nodules is related to excessive talking or improper use of the voice, such as in occupations like teachers, salespeople, and singers. Besides voice therapy, another treatment option is nebulizer inhalation, which is used to alleviate symptoms. Commonly used medications include corticosteroids, such as budesonide for nebulizer inhalation treatment, twice a day, one dose each time, but voice therapy is a prerequisite. Without voice therapy and correct voice usage, treatment with medication alone through nebulizer inhalation will not be effective, and the symptoms will not improve significantly. Some patients with vocal cord nodules do not need medication and can fully recover their normal voice and have the nodules disappear just by proper voice therapy and resting the voice for a period. Therefore, voice therapy is the best treatment for this condition.
How to prevent seasonal rhinitis
Seasonal rhinitis, also known as allergic rhinitis with seasonal outbreaks, requires the identification of specific allergens for its prevention. This type of rhinitis is caused by allergies to seasonal factors, so it is necessary to visit an allergen testing center at an ENT (Ear, Nose, and Throat) department of a hospital to determine the specific allergens. Then, prior to the season, preventative measures can be taken to avoid contact with these allergens. Medications can be started one or two weeks in advance to alleviate the symptoms of rhinitis. Common medications include anti-allergy nasal steroids and other anti-allergy drugs such as antihistamines and leukotriene antagonists. Nasal steroids are typically administered via nasal spray once or twice a day, and during the prevention period, it can be sprayed once a day.
What department should I go to for adenoid hypertrophy?
Glandular hypertrophy is a common condition in the field of otolaryngology, so for glandular hypertrophy, one should consult the otolaryngology department. The glands are located at the back of the nasal cavity, specifically in the nasopharyngeal area. Thus, when the glands are enlarged, it can cause various related symptoms in the ears, nose, and throat. The most common symptoms include nasal congestion, runny nose, snoring, mouth breathing, adenoid facies, secretory otitis media, and even suppurative otitis media. Therefore, in such cases, it is essential to visit the otolaryngology department of a hospital, undergo a nasopharyngoscopy to assess the extent of glandular hypertrophy, and decide on the appropriate treatment based on the specific diagnosis.
What will happen if nasal polyps are not operated on?
Nasal polyps are a common pathological change in otolaryngology, mainly caused by chronic inflammatory stimuli such as rhinitis and sinusitis, leading to changes in the nasal mucosa. Nasal polyps are an abnormal structural change. Once nasal polyps occur, emergency surgical treatment is recommended. If surgery is not performed, the polyps will continue to grow larger, altering some of the anatomical structures of the nasal cavity and occupying space, which can impair nasal function. This may lead to nasal congestion, a decrease in the sense of smell, and changes in the external nose, such as a "frog-like" nose; the nose becomes swollen and large, resembling a frog. Over time, due to poor nasal ventilation, this can cause headaches, a heavy head, and other uncomfortable symptoms, therefore urgent surgical treatment is advised.
What tests are needed for adenoid hypertrophy?
The adenoids are located at the back end of the nasal cavity in the nasopharyngeal area, so the examination needed for adenoid hypertrophy is generally the electronic nasopharyngoscopy. Electronic nasopharyngoscopy is a minimally invasive procedure that allows direct visual observation of the enlarged adenoids and the blockage of the posterior nasal apertures. Modern electronic nasopharyngoscopes are very thin; they can be inserted through the nostrils directly into the nasopharynx, providing a clear view of the adenoids with minimal discomfort and no radiation exposure, making it the preferred method. Another test that can be performed is a lateral X-ray of the nasopharynx. This examination has been a classic approach and is available in many township and county hospitals. It can accurately display the condition of adenoid hypertrophy and any airway obstruction. However, the only drawback is that it involves some level of radiation exposure.
How long does it usually take for vocal cord nodules to heal?
Vocal cord nodules are primarily caused by improper pronunciation or overuse of the voice, commonly seen in people who use their voices frequently. Treatment primarily involves vocal rest, which means speaking less and pronouncing correctly. The period of vocal rest usually needs to be relatively long. If the vocal cord nodules are larger, then an even longer period of vocal rest may be required, generally lasting from two to four weeks. Clinically, most cases require four weeks. The effects are generally better after resting for four weeks. During this period, treatment can be complemented with medications, such as nebulized inhalation, which can speed up recovery. The premise is to first undergo vocal rest followed by medication treatment, which generally takes about two to four weeks.
What should be noted after vocal cord polyp surgery?
The most important thing to pay attention to after vocal cord polyp surgery is to speak as little as possible, which means vocal rest. Typically, vocal rest should last between two to four weeks. The better you adhere to vocal rest, the better your voice will recover after the surgery. Once recovered, continue to minimize speaking and ensure correct pronunciation to prevent recurrence of vocal cord polyps. Another important consideration is avoiding environments with tobacco smoke; do not smoke and try to stay away from places where others are smoking. Diet should be light, avoiding spicy and stimulating foods. Also, manage your emotions in daily life; do not rush or shout, as this can affect your recovery. Even if you do not yell when anxious, it can still lead to a less than optimal post-operative recovery.
