Can pneumothorax resolve on its own if it's not severe?
Generally, mild cases of pneumothorax can resolve on their own. Pneumothorax refers to the accumulation of air in the pleural cavity, resulting in a buildup of gas. If symptoms are not severe, the condition usually resolves spontaneously. The specific analysis is as follows:
Pneumothorax often occurs when lung tissue and the visceral pleura rupture due to underlying lung disease or external force, or when small subpleural blebs rupture, allowing air from the lungs or bronchi to enter the pleural cavity, thus causing pneumothorax. In general, if the pneumothorax is mild and the patient does not experience significant chest discomfort, it can typically resolve without intervention.
It should be noted that if the volume of air in the pleural cavity is large—resulting in 30%–90% or more lung compression—and is accompanied by other symptoms, spontaneous recovery is unlikely. In such cases, medical treatment under a doctor's guidance is necessary, including thoracentesis (needle aspiration) or closed thoracostomy drainage. Antibiotics may also be administered to prevent or treat infection.
If patients develop any symptoms, they should seek prompt medical attention at a hospital to avoid delays in diagnosis and treatment.
