Your smoke is so good! When singing at KTV, Xiao Li was recognized by his colleagues, who felt that his voice was hoarse and he sang well. But he himself wondered that his voice used to be very clear, but when did it slowly become a "smoky voice". Unexpectedly, the next day, he suddenly lost his voice and had a sore throat, so he hurried to the nearest Chengdu Public Health Clinical Medical Center for treatment, and after an examination, he found that he was not suffering from influenza, but suffering from laryngeal tuberculosis.
Can you get tuberculosis in the throat? What's going on? Huang Yuhong, a tuberculosis doctor at the Municipal Public Health Center, hopes that through popular science, everyone can understand and pay attention to this sudden hoarseness.
Huang Yuhong said that laryngeal tuberculosis is a respiratory tract-borne disease caused by Mycobacterium tuberculosis infecting the larynx, which is mostly secondary to pulmonary tuberculosis. Most patients are due to hematogenous or lymphatic transmission of tuberculosis from the lungs or other organs, and a small number are due to direct infection.
The clinical symptoms of laryngeal tuberculosis are hoarseness and sore throat, which usually appear in the early stages of the disease. As the disease progresses, hoarseness can gradually worsen, and even loss of voice may occur in advanced stages, and in severe cases, laryngeal edema may occur, resulting in dyspnea and even suffocation. At the same time, patients may also be accompanied by laryngeal foreign body sensation, dysphagia, cough, sputum production, hemoptysis, weight loss, low-grade fever, night sweats and other symptoms.
Huang Yuhong said that some patients will think that they have a cold after experiencing hoarseness and sore throat, and buy cold medicine to eat, which not only has no effect, but also delays the condition. When symptoms develop, she said, you should seek medical attention in a timely manner based on your past medical history.
In the hospital, if laryngeal tuberculosis is suspected, the doctor will prescribe some checklists, first of all, you need to do a sputum smear to check for the presence of tuberculosis bacilli, and at the same time, you need a chest X-ray or CT scan to check for pulmonary tuberculosis; In addition, electronic laryngoscopy is needed to understand the larynx, and histopathological examination can be performed if necessary.
To be diagnosed with laryngeal tuberculosis, the following conditions need to be met:
First of all, the patient has symptoms such as hoarseness, sore throat, and inhalation dyspnea. Secondly, laryngoscopy can show that the mucosa is swollen, or hyperemic, or pale, and there may be insect erosion ulcers, and the bottom of the ulcer is granulation and tunica alba; The folds of the epiglottis and aryepiglottic folds may be thickened and edematous, and in some patients, the epiglottis may be partially defected due to the destruction of severe ulcers. Third, tuberculosis can be detected by chest x-ray or CT examination. Finally, sputum smear can be stained with acid-fast staining, and throat biopsy may show Mycobacterium tuberculosis or Langhan cells.
Huang Yuhong said that laryngeal tuberculosis can be **, and there is no need to be too nervous after diagnosis. Patients with laryngeal tuberculosis should receive standardized anti-tuberculosis**, and aerosolized inhaled antituberculosis drugs and glucocorticoids should be used to reduce mucosal edema and improve local symptoms. If the patient has edema in the larynx, causing difficulty breathing, a tracheostomy may be done to help relieve symptoms and relieve airway obstruction.
So, how can laryngeal tuberculosis be prevented? Huang Yuhong said that its prevention methods are more conventional: try to avoid contact with tuberculosis patients and wear masks in public; If you have tuberculosis or tuberculosis of other organs, you should try to ** as soon as possible to avoid secondary laryngeal tuberculosis. In addition, patients with laryngeal tuberculosis should be isolated from their families.
