What is the outcome (prognosis) of pneumothorax?
The outcome of pneumothorax depends upon the extent and type of pneumothorax. A small spontaneous pneumothorax will generally resolve on its own without treatment. A secondary pneumothorax associated with underlying disease, even when small, is much more serious and carries a 15% mortality (death) rate. A secondary pneumothorax requires urgent and immediate treatment. Having one pneumothorax increases the risk of developing the condition again. The recurrence rate for both primary and secondary pneumothorax is about 40%; most recurrences occur within 1.5 to two years.
