Abstract
The break-apart needle electrode system includes a pair of needle electrodes housed together in a fixed spaced-apart relationship. The needle electrodes are joined to electrical conductive wire for detachable connection to an electrical source. The needle electrodes are used in intraoperative facial nerve monitoring by facial electromyographic recording. Since the needle electrodes are furnished as a bipolar pair with twisted leads in a single break-away housing, they provide standardization, ease of placement and close bipolar recording. In instances where separate placement of needle electrodes is desired, the housing can be broken apart at a break-away joint. The needle electrodes are easily manipulated at the housing section as a tandem unit or as separate entities after the housing is broken apart.
