Intraoperative facial nerve monitoring is essential for acoustic neuroma surgery to preserve postoperative facial nerve function. The monitoring is now adopting for otologic surgeries such as cochlear implant and middle ear cholesteatoma. Several kinds of insulated dissector have been developed for identification and/or dissection of the facial nerve from tumor. However, the size and shape of the functional edge differ in each dissector. Here, wedeveloped new insulated dissectors by modification of Kanzaki model (Nagashima Medical Instrument). Our new model is Teflon-coated up to its functional edge, and consists of 11 dissectors having four different edges of pin, ball, knife and ring. The dissectors can be used by connecting with NIMPulseTMIntegrity Monitor (Medtronic XOMED).
