See Dr. Lamperti's latest intra-operative video that walks through how to treat chronic maxillary (cheek) sinusitis using endoscopic sinus surgery techniques.
I just uploaded a new surgery video that shows how to perform what is called a maxillary antrostomy. A maxillary antrostomy is a fancy term for opening up the natural cheek sinus opening where it drains into the nose. Check out the sinus surgery video itself here.
