What is a bilateral endoscopic sinus surgery?

Lets break it down: What you're describing is surgical exploration of the sinuses, using fibreoptic equipment, which involves both the left and right sides at the same setting. Good luck.

ESS: Hello, the term bilateral refers to the procedure being done on both sides of your sinuses. Using an endoscope, your surgeon will open your sinuses and remove diseased tissues and bone from the sinus cavities. You should feel well informed about this procedure before you sign consent. Know exactly what your doctor plans, risks, his/her results, expectations and alternative treatments. Good luck.
