Voices
Are vocal cord nodules prone to recurrence?
Vocal cord nodules are symmetrical nodular protuberances on the free edges of both vocal cords. Clinically, vocal cord nodules are mainly related to improper use of the voice and are prone to recurrence. Recurrence factors primarily involve inappropriate voice use, voice abuse, and other irritants such as tobacco, alcohol, chili peppers, and other spicy foods, as well as frequent recurring upper respiratory infections. Therefore, clinically, in addition to medication, such as drugs that clear the throat and benefit the voice, attention should also be paid to diet structure and normal voice use to avoid excessive voice abuse.
What department should I go to for throat cancer?
Laryngeal cancer is a malignant tumor of the larynx. Therefore, initially, one should consult the otorhinolaryngology department. However, in some specialized hospitals, such as cancer hospitals, there might not be a specific otorhinolaryngology department, but there is a head and neck surgery department, so in that case, one should consult the head and neck surgery department. After surgery for laryngeal cancer, comprehensive treatment including chemotherapy and radiotherapy is required. Thus, post-surgery, if radiotherapy is needed, one should visit the radiotherapy department, and if chemotherapy is needed, one should visit the oncology department. Generally, the decision for surgical, radiotherapy, and chemotherapy treatments is based on the condition of the disease.
How to check for otitis media
Otitis media is a common and frequently occurring disease in our department of otolaryngology and head and neck surgery. It is an inflammatory disease of the middle ear. There are many clinical examination methods, mainly the following: First, we use our forehead mirror to directly visualize the external auditory canal, tympanic membrane, and tympanic cavity. That's one method. Next, we can examine our middle ear using instruments such as an otoscope or an endoscope, which allow direct observation of the middle ear structure and the tympanic membrane. The third examination focuses on the auditory function in otitis media. We can conduct pure tone audiometry and check acoustic impedance to assess the condition of our hearing function. Additionally, we perform imaging studies, such as a CT scan of the temporal bone or mastoid to observe the condition of our middle ear cavity.
Observation of the condition in suppurative tonsillitis
Suppurative tonsillitis is an emergency in clinical practice and is a more severe form of acute bacterial tonsillitis. Clinically, it mainly presents as severe throat pain and systemic symptoms such as chills and fever, indicating a serious infection state or symptoms. Therefore, the clinical treatment of suppurative tonsillitis mainly involves anti-infection treatment through infusion. Clinical observation should focus on the condition of the throat area, such as swelling in the throat and the presence of purulent secretions from the tonsils. Secondly, the overall condition of the patient should be observed, including fever, whether the fever subsides or the duration of the fever. Thirdly, the patient's complete blood count can be observed, specifically the white blood cells and neutrophils, which indicate infection, to see if their levels are returning to normal. Other observations can include the renal and urinary system, checking for the presence of red blood cells and proteins.
What medicine is used for suppurative tonsillitis?
Purulent tonsillitis is clinically mainly due to infections caused by Staphylococcus aureus, hemolytic streptococcus, and other bacteria. It is an acute and severe infection of tonsillitis, and the primary clinical treatment is the use of antibiotics. For example, antibiotics that are administered orally or intravenously, mainly cephalosporin antibiotics are used. If allergic to cephalosporin antibiotics, macrolide antibiotics are used for treatment. Additionally, some Chinese patent medicines that clear heat and detoxify can also be used as adjunctive therapy, such as Ban Lan Gen oral liquid and Yi Qing capsules. The throat can also be treated with some washes; for example, hydrogen peroxide gargle or some commercially available mouthwash can be used for gargling, etc. (Please use medication under the guidance of a professional doctor, do not self-medicate.)
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.
