Explanation

Primary spontaneous pneumothorax is likely due to:

• the formation of small sacs of air (blebs) in lung tissue that rupture
• causing air to leak into the pleural space

Air in the pleural space creates pressure on the lung and can lead to its collapse.

Explanation

The pterygopalatine ganglion is most likely to be affected in a 64-year-old male presenting with dry eyes.
