Can throat cancer be cured?
Laryngeal cancer is a malignant tumor located in the larynx, which can be classified into supraglottic cancer, subglottic cancer, glottic cancer, and transglottic cancer. Any malignant tumor is not incurable; it mainly depends on how early it is detected. If laryngeal cancer is discovered early and treated correctly, promptly, and appropriately, the primary treatments include surgery, radiotherapy, and chemotherapy, among others. Under these conditions, the survival rate, cure rate, and life expectancy are quite high. However, if the laryngeal cancer has reached an advanced stage and has metastasized to other parts of the body or distant organs, the prognosis is poor, and the survival rate is relatively low.
Can nasal septum deviation be treated under general anesthesia?
Nasal septum deviation refers to the deviation of the cartilage and bone tissue of the nasal septum towards one or both nasal passages, causing symptoms such as nasal congestion, blood-tinged nasal discharge or nosebleeds, and headaches. After the deviation of the nasal septum, nasal congestion can cause symptoms of snoring. Surgery for nasal septum deviation or other operations can be performed under general anesthesia. The deviated nasal septum does not affect the state of anesthesia. However, due to the presence of a deviated nasal septum, oral intubation should be chosen instead of nasal intubation during general anesthesia. If nasal intubation is desired, it should be performed on the side with a wider nasal passage. Thus, attention should be paid to the choice of intubation location during surgery under general anesthesia.
What should I do if otitis media is causing pus discharge?
Otitis media refers to various inflammations of the middle ear cavity, primarily bacterial inflammation. These bacteria are mainly Staphylococcus aureus and Streptococcus pneumoniae. Otorrhea in otitis media indicates relatively severe inflammation and the occurrence of a tympanic membrane perforation, allowing the purulent discharge to be expelled from the ear. In addition to indicating severe inflammation of otitis media, it is necessary to use antibiotics to control the infection. This can include topical antibiotic ear drops like compound polymyxin B ear drops and oral cephalosporin antibiotics, as well as intravenous infusion of cephalosporins to treat the infection.
The differences between chronic pharyngitis and acute pharyngitis
There is a fundamental difference between the two; chronic pharyngitis is a chronic inflammatory disease, while acute pharyngitis is an acute inflammatory disease. Furthermore, the symptoms of chronic pharyngitis are not very prominent in clinical settings, presenting only as a foreign body sensation or other discomforts. In contrast, the symptoms of acute pharyngitis are quite significant, such as sore throat, and may even include systemic symptoms like chills and fever. Thirdly, during examination of chronic pharyngitis, one can observe congestion of the pharyngeal mucosa, which is a type of chronic congestion. However, the congestion in acute inflammation is acute and very pronounced. There are also significant differences in treatment. For chronic inflammation, the clinical approach mainly involves administering heat-clearing and detoxifying traditional Chinese medicines, and sometimes no medication is used at all; just focus on hydrating locally without the need for any special medication. In contrast, acute pharyngitis requires medication to manage the acute inflammatory symptoms. In summary, there are fundamental differences between chronic and acute pharyngitis, whether it is in symptoms, treatment, or the pathological state of the mucosa.
Can a deviated nasal septum cause rhinitis?
A deviated septum refers to the condition where the cartilage and bone tissues of the nasal septum are skewed towards one side of the nasal cavity. This structural deviation can lead to nasal congestion, nosebleeds, and even headaches. If these symptoms are not present, it might be that the septum is deviated but not severely so. However, if these symptoms do appear, then it is necessary to address the deviated septum. There is an inevitable connection between a deviated septum and rhinitis, meaning a deviated septum will certainly lead to rhinitis. Rhinitis involves inflammation of the nasal mucosa. Therefore, the presence of a deviated septum will definitely cause rhinitis. Thus, actively treating a deviated septum greatly aids in the recovery from rhinitis.
Have you checked for allergens for allergic rhinitis?
Allergic rhinitis is a disease characterized by an allergic reaction to external substances. Since it involves allergies to external substances, it is necessary to identify what triggers the allergy, generally requiring an allergen test. Without testing the causes of allergies, the treatment is merely based on experience or a clinical diagnosis lacking in etiological understanding, which is insufficient from a pathological perspective. Moreover, after identifying the allergens, medication can be tailored according to the allergens, or general advice can be given to the patients, such as avoiding certain allergy-inducing substances. For instance, mangoes are commonly known to trigger allergies, and so are fish and seafood, thus specific guidance can be provided to avoid consuming certain foods.
Do vocal cord nodules require surgery?
Vocal cord nodules refer to symmetrical nodular elevations that appear on the free edges of both vocal cords. These nodules are mostly grain-like or granular protrusions. Vocal cord nodules are often caused by incorrect pronunciation, overuse of the voice, or screaming loudly, which are inappropriate vocal habits. Generally, most vocal cord nodules will disappear on their own after resting the voice, speaking less, and using the voice correctly. Therefore, as explained above, vocal cord nodules do not require surgical treatment. Surgery is only necessary if the vocal cord nodules continue to develop uncontrollably, evolving into vocal cord polyps or other pathological changes.
Conservative treatment methods for adenoid hypertrophy
Adenoid hypertrophy refers to the enlargement of glandular tissue located in the nasopharynx, which blocks the nasal cavity or obstructs the pharyngeal opening of the Eustachian tube, leading to otitis media. Patients may experience symptoms such as snoring during sleep. Conservative treatment for adenoid hypertrophy mainly refers to medication therapy for enlarged glands. Medications such as mometasone furoate and montelukast sodium can be used, as well as inhalation therapy with medicated mists. Inhalation therapy primarily involves nasal cavity inhalation, such as using sprays. Overall, the efficacy of conservative treatment for adenoid hypertrophy is relatively poor. Therefore, it is necessary to assess the condition comprehensively and consider timely surgical treatment if necessary.
Treatment methods for otitis media with effusion
Otitis media with effusion mainly refers to a type of secretory otitis media, where there is negative pressure in the middle ear cavity and fluid accumulation occurs. Treatment usually begins with medications, lasting either one to three months or three to six months. Antibiotics, steroids, and medications that facilitate the drainage of the effusion, such as Mucosolvan, may be used. Additionally, medications that constrict the mucosal blood vessels in the nasal cavity can also be used to facilitate the function of the Eustachian tube. If medication does not relieve or cure the condition, invasive treatment methods such as tympanic membrane puncture, tympanotomy, tympanostomy tube insertion, and Eustachian tube balloon dilation can be employed.
Is T2N0M0 throat cancer serious?
Laryngeal cancer T2N0M0 refers to Stage 2 clinical staging of laryngeal cancer. Here, "T" denotes the primary lesion, typically classified as Stage 2. Stage 1 generally refers to the primary tumor, with Stage 2 lesions being larger in scope than Stage 1. "N0" indicates the local lymph nodes, showing that there is no local lymph node metastasis. "M0" indicates there is no distant metastasis. Therefore, laryngeal cancer T2N0M0 represents an early or intermediate stage. Clinically, this stage is usually most suitable for surgery, and the healing and prognosis after surgery are relatively favorable.
