Tuberculosis cavities that cannot be closed after treatment can be treated by medication, surgery and other ways of treatment. 1. Drug treatment: the treatment of tuberculosis cavity is not an overnight thing, so if the tuberculosis cavity can not be healed after treatment, first of all, we must continue to insist on anti-tuberculosis treatment, and follow the doctor’s instructions to take anti-tuberculosis drugs (such as isoniazid, rifampicin, etc.), to achieve regularity, sufficient amount, and full course of treatment. 2. Surgery: For those with tuberculosis cavities that have not been treated with chemical drugs, surgery can also be considered. When the cavities are still not closed after long-term treatment, and when they are in the process of continuous excretion of bacteria or complicated by hemoptysis, it is recommended that lung resection be carried out, and the specific surgical method needs to be formulated by the doctor according to the actual condition. Tuberculosis itself is stubborn and easy to recur, therefore, when individuals face the lung cavity caused by tuberculosis, they must cooperate with the doctor for treatment in time and pay attention to make reasonable adjustments to the treatment plan through regular review.
