Can a deviated nasal septum heal on its own?
The clinical diagnosis of a deviated nasal septum includes two parts. Firstly, there is a structural deviation of the nasal septum, where the cartilage and bone tissues lean towards one side of the nasal cavity. This deviation could appear in various forms, such as S-shaped bends or conical deviations. Secondly, these deviations cause nasal symptoms, such as chronic nasal congestion, nosebleeds, and even headaches. Both of these symptom parts are required to diagnose a deviated nasal septum, which can then be treated surgically. Since it is known to be a structural deviation, which is mechanical in nature, a deviated nasal septum cannot recover on its own and requires surgical intervention.
Is nebulization effective for pharyngitis?
Pharyngitis is caused by various reasons and is an acute and chronic infection of the throat, characterized by sore throat, hoarse voice, and various foreign body sensations in the throat. The basic pathological changes are the congestion and edema of the pharyngeal mucosa, including both acute and chronic congestion. Therefore, nebulization treatment mainly works through the nebulized particles directly affecting the mucosa of the throat. Medications such as gentamicin and dexamethasone have a direct effect in reducing the mucosal edema of the throat. The effect of nebulization for pharyngitis is quite good as it directly affects the mucosa. For some patients, it is necessary to combine nebulization with oral medication, and generally, the combined treatment is very effective. (Specific medications should be used under the guidance of a physician.)
Do nasal polyps definitely have to be removed?
Nasal polyps are benign glandular tissues that occur in the nasal cavity. The presence of nasal polyps can block the nasal passage, leading to secondary infections, and as nasal polyps gradually increase in size, they can damage the local tissue structure. Therefore, once nasal polyps appear, they are primarily removed through surgery, making surgical removal necessary. However, in the early stages of nasal polyps, when they have just developed and are still small, they can be treated with medications such as methylprednisolone or prednisone. These drugs are mainly corticosteroids and can cause the polyps to gradually shrink and disappear in a minority of patients, a process referred to as chemical resection through medication. Nonetheless, the chance of detecting nasal polyps in their early stages is very small, and they are often only discovered when they have grown large enough to obstruct the nasal passage and affect breathing, meaning that they typically require surgical removal after they are found.
How to treat enlarged turbinates and a deviated nasal septum?
For the condition of enlarged turbinates and a deviated nasal septum, we need to understand that these are pathological changes in the anatomical structure of the nose. In dealing with anomalies in the anatomical structure, our first step should be to perform a CT scan, then assess the extent of the enlargement of the turbinates and the deviation of the nasal septum. If the condition is severe, and there are relatively prominent symptoms such as nasal congestion, nosebleeds, and even headaches, then we should consider correcting these abnormal structures surgically, by removing these anomalies or correcting the deviated nasal septum or addressing the factors causing the turbinate hypertrophy. If there are no significant symptoms or only minor deviation or enlargement, treatment usually involves medication, primarily nasal sprays such as intranasal corticosteroids. In summary, there are mainly two treatment methods: surgical and medical treatments.
How is otitis media caused?
Otitis media primarily refers to the inflammation of the tympanic membrane, tympanic cavity, and mastoid in the middle ear. Clinically, the main causes of otitis media include the following: firstly, infectious factors, which are mainly bacterial infections. Bacteria can infect the middle ear through the external auditory canal, through the Eustachian tube from the nasopharynx to the tympanic cavity of the middle ear, or via the bloodstream to the tympanic cavity, tympanic membrane, and mastoid, leading to symptoms of otitis media. These are our pathways of infection. So, what causes these infections? Or what factors might influence the occurrence of these infections, that is, the occurrence of otitis media? Key factors include decreased immunity in children, increased virulence of bacterial infections, which involves highly infectious bacteria, and our anatomical structure, namely, the imperfection or incompleteness of the middle ear structure and the anatomical connections between the ears.
What should be paid attention to with otolithiasis?
Clinically, ear stone syndrome is referred to as benign paroxysmal positional vertigo. Concerning this condition, the following points should be noted: Firstly, active treatment is essential, primarily involving manual or mechanical repositioning, as well as functional exercises after repositioning; this is mandatory. Secondly, safety precautions must be taken. Patients with ear stone syndrome should not be near the edges of high buildings or ponds to prevent unforeseen accidents that could be triggered by sudden bouts of vertigo. Thirdly, dietary habits are important. The diet should be light, and stimulating substances such as tobacco, alcohol, spicy foods, and coffee should be avoided. Lastly, it is important to avoid excessive exercise, particularly activities involving too much spinning.
Does acute pharyngitis recur easily?
Relatively easy. Acute pharyngitis is an acute inflammatory disease of the pharyngeal mucosa, and acute pharyngitis can also be part of an upper respiratory tract infection. Clinically, the main manifestations of acute pharyngitis are pain in the throat, and severe cases may exhibit symptoms like chills and fever. We can observe that the mucous membrane of the throat is highly congested, and there may even be purulent secretions. After treating acute pharyngitis clinically, it is relatively easy for it to recur. This is because our usual diet of spicy and irritating foods, or foods that are too cold or too hot, can adversely stimulate the mucous membrane of the throat. At the same time, if we are prone to catching colds, the cold itself will affect the mucous membrane of the pharynx, thus making acute pharyngitis clinically prone to recurrence.
Is suppurative tonsillitis uncomfortable?
Suppurative tonsillitis is an acute infection of the tonsils, which is relatively severe and involves purulent changes in the tonsils. Clinically, patients experience severe throat pain, which worsens during swallowing and may even lead to difficulty in eating. Patients may also experience symptoms such as chills and fever. Therefore, suppurative tonsillitis is very distressing, and we need to actively manage it. Generally, we conduct a blood test to check the routine blood parameters and observe the level of white blood cell infection, that is, the white blood cell count. Then, we administer intravenous infusions of antibiotics for treatment.
What should I do if nasal polyps are removed but grow back?
Nasal polyps are a common condition in otolaryngology and are benign neoplasms in the nasal cavity. After nasal polyp surgery, there is a possibility of recurrence, and the likelihood of recurrence is relatively high compared to other diseases. Currently, we surgically remove nasal polyps through functional endoscopic surgery, followed by regular post-operative outpatient follow-ups to clean the nasal cavity. Since then, the recurrence rate after this surgery has been relatively low. However, if the nasal polyps recur, we must perform surgery again to remove them, as enlarged nasal polyps can block the nasal cavity and damage the surrounding tissue structures, necessitating another surgical intervention, with no other special methods available.
The difference between nasal polyps and adenoids
There are fundamental differences between nasal polyps and adenoids. Nasal polyps are polypoid tissue proliferations located in the nasal cavity and sinus cavities, resembling a peeled lychee. In contrast, adenoids are located in the nasopharynx and are a normal anatomical structure of the human body, whereas nasal polyps are a new benign tumor-like growth. Furthermore, nasal polyps require surgical removal, primarily through functional endoscopic sinus surgery. Adenoids generally do not require surgical treatment unless they are enlarged, causing issues such as snoring and sleep apnea, in which case surgery might be considered.
