Once access to a blocked sinus is confirmed, a balloon catheter is advanced over the guide wire and positioned in the blocked sinus opening for inflation. The balloon is inflated. The entire procedure takes around 31 minutes and if the procedure is successful, the sinus will remain open after the balloon is deflated and removed for up to 24 months.
The sinus will fill with fluid or blood unless the pressure differential is neutralized. [6] If the outlet is blocked during ascent, the situation is reversed and "reverse squeeze" appears. [7] Pressure inside the sinus increases, affecting the walls of the sinus and producing pain or epistaxis.

Nasal obstruction characterized by insufficient airflow through the nose can be a subjective sensation or the result of objective pathology.
