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.
Is chronic rhinitis contagious?
Chronic rhinitis is a chronic inflammatory disease of the nasal mucosa. Clinically, it can be divided into simple, hypertrophic, and atrophic types. The treatment generally primarily involves the use of local medications, and typically does not involve the use of antiviral or antibiotic medications. Chronic rhinitis is not contagious. However, it is important to be aware of other conditions that can cause chronic rhinitis, such as tuberculosis-induced rhinitis and syphilitic rhinitis. These are not cases of the rhinitis itself being contagious, but rather the transmission of pathogens, so it cannot be simply stated that chronic rhinitis is contagious. Clinically diagnosed chronic rhinitis is definitively non-contagious.
Is throat cancer easy to treat?
Laryngeal cancer is a malignant tumor in the larynx, clinically mainly squamous cell carcinoma. Currently, the main treatment is comprehensive treatment centered around surgery, including surgical radiation therapy and chemotherapy. Laryngeal cancer can be completely cured if detected early. It is divided into three types: supraglottic, glottic, and subglottic cancer. Glottic cancer, due to the early and noticeable symptom of hoarseness, is usually detected early, thus the clinical treatment outcomes are relatively good. Therefore, laryngeal cancer is among the malignant tumors with relatively good treatment outcomes, and is considered relatively easy to treat. In summary, the current treatment outcomes for laryngeal cancer are still quite good.
What should I do about turbinate hypertrophy?
Clinically, turbinate hypertrophy is mainly caused by the stimulation of inflammatory factors such as acute and chronic rhinitis and sinusitis, leading to the proliferation of the turbinate, including the mucosal and even bony growth, as well as congenital developmental factors causing turbinate enlargement. Initially, treatment typically involves medication, using nasal sprays such as corticosteroids for nasal treatment. Secondly, surgical treatment can be employed. We can assess the extent of turbinate hypertrophy with a nasal CT scan to determine if there is bony enlargement. If there is bony hypertrophy, partial resection of the submucosal turbinate bone can be performed. If the hypertrophy is only in the mucosal and soft tissue, it can be treated using plasma ablation. In summary, turbinate hypertrophy can be treated with medication or surgery, depending on the specific extent of the pathology.
Common sites of laryngeal cancer
Laryngeal cancer is a malignant tumor in the larynx, and clinically, it is primarily squamous cell carcinoma. There are several types of laryngeal cancer: firstly, glottic cancer; secondly, supraglottic cancer; there is also subglottic cancer, and transglottic cancer that spans two regions. Among these types, glottic cancer is the most common. Early-stage glottic cancer is generally detected earlier due to hoarseness, and the outcomes after surgery are relatively better. Consequently, the most frequently diagnosed site of this disease is the vocal cords. After surgery, regular follow-up appointments are necessary to monitor and observe the healing process post-operation.
What fluid should be administered for suppurative tonsillitis?
Purulent tonsillitis is a serious infectious disease clinically, mainly manifesting as severe pain in the pharyngeal area, general malaise in patients, and even symptoms such as chills and fever. Therefore, active treatment is required. Clinical treatment is mainly anti-infection treatment. Infusion primarily uses cephalosporin antibiotics such as ceftriaxone and cefazolin for treatment. To enhance the anti-infection effect and reduce the edema of the patient's throat mucosa, corticosteroid drugs such as dexamethasone or prednisolone are often used simultaneously in the infusion treatment.
