Eyebrow incision with supraorbital trephination for endoscopic corpus callosotomy: a feasibility study.

OBJECTIVE

We describe a novel technique for the partial bisection of the corpus callosum in order to increase the minimally invasiveness of this procedure.

METHODS

Brow incisions with midline trephinations were performed in six adult cadavers. An endoscope was next introduced and used to transect approximately the anterior two-thirds of the corpus callosum.

RESULTS

No complications such as injury to the superior sagittal sinus or anterior cerebral artery were encountered in any of our cadaveric specimens. The corpus callosum was easily transected in each specimen.

CONCLUSION

As a feasibility study, we believe this technique could provide a less invasive mechanism for patients who require corpus callosotomy and will minimize much of the morbidity associated with the traditional methods of sectioning the corpus callosum.
