In patients with sinonasal disease, recognition of anatomic landmarks may be difficult. The ISG Viewing Wand is an intraoperative navigational device that allows the surgeon to correlate the anatomy of the patient with a computerized display of the reformatted image of preoperative computed tomographic or magnetic resonance scans. We have found the ISG Viewing Wand to be a valuable tool for surgery of the paranasal sinuses. Representative cases are presented that illustrate the application of this device. An intraoperative navigational device enhances the surgeon's ability to safely identify anatomic structures.
