The removal of clival lesions, mainly those located intradurally and with a limited lateral extension, may be challenging because of the lack of a surgical corridor that would allow exposure of the entire lesion surface. In this anatomic study, we explored the clival/petroclival area and the cerebellopontine angle via both the endonasal and retrosigmoid endoscopic routes, aiming to describe the respective degree of exposure and visual limitations. ⋯ Different endoscopic surgical corridors can be delineated with the endonasal transclival and retrosigmoid approaches to the clival/petroclival area. Some relevant neurovascular structures may limit the extension of the approach and the view via both routes. The combination of the 2 approaches may improve the visualization in this challenging area.

To determine whether a novel bipolar forceps device that uses heat-pipe technology to manage tissue temperature would result in less tissue injury compared with a conventional antistick forceps design. ⋯ Bipolar forceps containing heat pipes more effectively limits excessive thermal spread, thereby potentially reducing the risk of unintended injury to collateral or peripheral tissue.
