CHRONIC SINUSITIS IN CATS

• Etiology - secondary viral or bacterial  infections.

Treatment

• Sinus flushing  - This is performed through a trephine hole made just lateral to the midline on a line joning the rostaral margins of the supra orbital process. An intravenous tubing is usually preferred to flush with trypsin solution

Sinus drainage

• This is more radical approach. Periostium is elevated  to remove the bony layer over the sinus with rongeurs to effect drainage
