Functional Endoscopic Sinus Surgery

The Maxillary sinus is the largest of the paranasal sinuses. The maxillary sinus, ethmoid sinus, and frontal sinus drain into the middle meatus of the nose. Problems arise from the sinuses due to the close anatomical relationships of all of the sinuses allowing easy spread of infection.

Sinus surgery involves the removal of the soft tissue and bone covering the maxillary sinus. Removing the soft tissue and bone will widen the maxillary sinus allowing drainage of the infected sinus. Disease in the ethmoid sinus cells and maxillary sinuses are then cleared.

 

Once disease is cleared the opening will now provide air circulation, clear drainage and prevention of sinusitis. Most importantly open sinuses will allow better penetration of salt water and nasal sprays.
