The vast majority of cavitary TB can be cured after systematic and standardized anti-tuberculosis treatment. If the cavities in cavitary TB are small, they may retract and close after long-term anti-tuberculosis treatment. However, if the cavity is relatively large, the cavity will not be able to close completely and small cavities will remain after the cavitary TB is cured. Cavitary TB is one of the common types of TB, which is contagious and spreads mainly through droplets. Clinical symptoms commonly include weakness, cough and hemoptysis. The treatment of cavitary TB is basically the same as that of other types of TB, and is based on drug treatment, including intensive treatment and consolidation treatment. Isoniazid tablets, rifampicin tablets and ethambutol hydrochloride tablets are usually used in the intensive phase, and only the first two drugs can be used in the consolidation phase. Doctors will consider surgical treatment if necessary, and most patients can achieve clinical cure. Therefore, when cavitary tuberculosis occurs, you must go to the hospital as soon as possible, and use reasonable medication and treatment under the guidance of the doctor.
