Recentry the number of surgeons who use powered instrumentations (microdebrider) for ESS has increased in Japan because the usability and safety of these devices have been recognized. In order to evaluate the new microdebrider systems, i.e., Hummer 2 (Stryker Corp, USA) and XPS (Xomed Corp, USA), we performed endoscopic sinus surgery for 26 cases with chronic sinuitis using these new devices from November to December 1997, and compared the new microdebrider systems and Hummer system for the usability. As a result, the advantages of these new devices are as follows : 1) There is less plugging of aspiration during operation by using more powerful handpiece and irrigated double cutter blades, 2) these new devices also enables bony dissection, such as the bony partitions in the ethmoid labyrinth and bony borders of the maxillary ostium, and 3) the XPS system can also be used for bone work by using the drill bar. These new devices will be able to dissect the frontal recess and maxillary sinus by using curved blades (Hummer 2 has a 15-degree angle, XPS 40-degree angle), and therefore we will be able to approach almost entire sinuses easier. The new microdebrider systems can overcome the Hummer's weakness almost completely. We require more thicker cutter blades about 5 mm in diameter, because most patients with chronic sinuitis in Japan have more severe polypoid lesion and surgical area which is mostly more expanded than FESS, compared to those in USA and Europe.
