As experience with endoscopic sinus surgery (ESS) has grown, the techniques and equipment have been found to be adaptable to treatment of lesions of the skull base. Image-guided surgery is also helpful to safety expand minimally invasive transnasal endoscopic techniques for the skull base diseases. This system has been proven to facilitate complicated ESS and decrease the need for revision procedure.
