Symptoms of acute tonsillitis
Acute tonsillitis is an acute infectious disease of the tonsils, primarily caused by bacterial infection. Clinically, it mainly manifests as pain in the throat area, and sometimes the pain is very severe, even radiating to the base of the ears and down to the jaw. Additionally, there might be systemic symptoms such as loss of appetite, overall lethargy, weakness in the limbs, fever, night sweats, and chills. Generally, the presence of systemic symptoms indicates a severe infection of tonsillitis, requiring treatment through intravenous fluids. Clinical examinations can reveal enlarged tonsils, congested surfaces, and the presence of pin-point-like gray or white purulent secretions.
Treatment course for acute tonsillitis.
Acute tonsillitis is an acute, infectious inflammation of the tonsils, primarily caused by bacterial infection. For the treatment of acute tonsillitis, we mainly adopt antibiotic treatment for infection. The general course of treatment lasts 7-10 days, especially for acute suppurative tonsillitis, which may even extend to about 10-14 days. Clinically, we primarily administer cephalosporin antibiotics to control the infection. If the infection is severe, we may even opt for infusion therapy to counter the infection. During the infusion, we can administer some corticosteroids such as dexamethasone to treat concurrently, enhancing the anti-inflammatory effect. Clinically, we should pay attention to drinking plenty of water and eating a light diet, avoiding spicy and irritating foods.
Is surgery necessary for nasal polyps?
Nasal polyps are benign neoplasms that occupy the spaces of the nasal cavity and sinuses. Clinically, once nasal polyps appear, they are generally removed through surgery. Currently, the main clinical approach is functional endoscopic sinus surgery. For some early-stage small nasal polyps, medications such as corticosteroids, methylprednisolone, and prednisone can be used for treatment, which can cause the gradual disappearance of very small polyps, a process known as chemical resection. In clinical practice, when nasal polyps are detected, they are usually relatively large, so once polyps are discovered during a hospital visit, treatment is typically conducted through surgery.
The difference between nasal polyps and hypertrophy of the nasal turbinates.
Nasal polyps are neoplasms located in the nose, nasal cavity, or sinus cavity, typically appearing as fully developed, translucent, lychee-like growths that are benign. In contrast, hypertrophy of the nasal concha involves swelling and thickening of the mucous membrane of the concha itself, which may partly demonstrate changes resembling nasal polyps, but it is not identical to nasal polyps. Nasal polyps do not have nervous or vascular supply, whereas the nasal concha does. Clinically, there are different treatments for each; nasal polyps usually require surgical removal, while treatment for hypertrophy of the nasal concha depends on the specific cause. If the hypertrophy is simple, it is often treated with medication; if it is hypertrophic, decisions on surgical intervention may depend on results from CT scans or X-rays.
Can suppurative tonsillitis heal itself?
Purulent tonsillitis is a relatively severe acute infectious inflammation of the tonsils, clinically characterized by severe throat pain and difficulty swallowing, even leading to difficulty in eating. The pain worsens during swallowing, and patients may experience symptoms like chills and fever. Therefore, purulent tonsillitis generally cannot heal on its own and requires active intervention. Active anti-infection treatment is necessary, as it cannot be expected to resolve spontaneously. Clinical treatment primarily involves the use of antibiotics, such as cephalosporins, and may even include infusion and other anti-infection treatments.
Can nasopharyngeal carcinoma be treated?
Nasopharyngeal carcinoma is a common clinical disease, especially in the southern regions of China. It primarily affects the nasal area as a malignant tumor. The clinical treatment outcomes for nasopharyngeal carcinoma are relatively good, and it is also referred to as "fortunate cancer," which implies that it has a relatively high cure rate. The main clinical treatment involves radiation therapy combined with chemotherapy, often described as the "sandwich" treatment method. Any tumor can be cured if detected early, and the early detection rate of nasopharyngeal carcinoma is relatively high. Therefore, its cure rate is also relatively high compared to other major organ tumors such as liver and lung cancers, which exhibit relatively lower cure rates and outcomes.
Can adenoid hypertrophy recur after removal?
The adenoid is located in the lymphatic epithelial tissue of the nasopharyngeal area. Enlargement of the adenoid can block breathing and obstruct the pharyngeal opening of the Eustachian tube, leading to secretory otitis media, and may result in secondary infections of the sinuses. Therefore, for symptoms such as snoring and hearing loss that occur simultaneously after adenoid enlargement, surgical removal is performed. The adenoid does not have a complete capsule, so it is only possible to remove the adenoid tissue as much as possible, and it cannot guarantee the complete removal of all adenoid tissue. Therefore, there is a small rate of recurrence after adenoid removal, with a recurrence rate of about 0.5%, meaning that the recurrence leading to the reappearance of symptoms is around 0.5%. Whether further treatment is needed after recurrence requires an in-person assessment at a hospital.
Do you need a laryngoscopy for pharyngitis?
Pharyngitis refers to the inflammation of the mucous membrane of the throat, which can be acute or chronic. Clinically, it mainly presents symptoms such as throat pain and a foreign body sensation in the throat, along with other symptoms. Pharyngitis can generally be diagnosed through a local examination or laryngoscopy, which fulfills clinical requirements. For recurrent pharyngitis or clinically severe cases, an electronic laryngoscopy may be necessary to check for any growths in the pharynx or on the vocal cords, as this examination can clearly determine the condition and guide clinical treatment. Therefore, it is necessary to perform a laryngoscopy for pharyngitis.
Does otitis media require intravenous therapy?
Otitis media refers to acute or chronic inflammation of the tympanic membrane, tympanic cavity, or mastoid cavity. Whether otitis media requires intravenous (IV) therapy mainly concerns acute suppurative otitis media. Generally, if the symptoms of otitis media are mild, such as ear pain without ear discharge, fever, headache, etc., IV therapy is usually not necessary. If the patient's symptoms are severe, such as intense ear pain, discharge from the ear, or even fever and other systemic symptoms, then IV anti-infection treatment should be considered. It is also common to perform a complete blood count to check the number of white blood cells; a high white blood cell count further supports the need for IV anti-infection treatment.
Can vocal cord polyps be examined by B-ultrasound?
Vocal cord polyps are benign space-occupying lesions of the vocal cords, mainly appearing as polypoid protrusions on the surface of the free edge of the vocal cords, sometimes with a thin stalk, and sometimes with a broad base. In clinical practice, vocal cord polyps are primarily examined using a laryngoscope, and can also be assessed via CT and MRI. However, ultrasound is not used to examine vocal cord polyps, as ultrasound produces many artifacts and the neck’s muscles and soft tissues are very rich, preventing ultrasound from correctly or fully displaying the condition of the vocal cord polyps. In summary, ultrasound is not used clinically to examine vocal cord polyps.
