Osteoplastic endonasal approach to the maxillary sinus

A new surgical approach for removal of isolated maxillary sinus pathology, mainly of symptomatic maxillary sinus cysts, is presented. It is based on the principles of osteoplastic sinus surgery and uses the transnasal approach. It allows a safe removal under direct vision or endoscopic control with standard surgical instrumentation. The normal maxillary ostium and healthy ethmoidal cells are not sacrificed and thus the lymphatic pathways as well as the mucociliary transport are not endangered.
