Objective: Contralateral C7 nerve root transfer surgery has been successfully applied to rescue motor function of a hemiplegic upper extremity in patients with central neurological injury. This surgical technique is challenging, and limited anatomical space makes it difficult to manipulate tissues and may lead to higher complication rates. The authors hypothesis a new surgical route in which cervical nerve roots of both donor and recipient sides are exposed from a posterior intradural approach and neurorrhaphy is performed easily and clearly. ⋯ Multiple anastomoses of C7 to various nerve roots on the contralateral side could also be performed within the same surgical field with an interposition nerve graft. Conclusion: The posterior intradural repair idea affords many advantages, the pathway is shorter and more straightforward, which provides more access to multiple nerve roots repair in one surgical field, and is more familiar to many neurosurgeons and spine surgeons. It may potentially be adapted for clinical use.

Purpose: Clival Chordomas are locally aggressive tumours which pose a significant treatment challenge. Endoscopic endonasal approach for clival chordomas is correlated with higher resection rates and lower morbidity rates in comparison to open approaches. We present our initial single institution experience and short-term patient outcomes following endoscopic endonasal approach for resection of clival chordomas. ⋯ Both cases of subtotal resection demonstrated evidence of progression with one dying of unrelated cause during the follow up period. Conclusion: Endoscopic endonasal approach represents a safe technique for debulking and resection of clival chordomas. Due to the rarity of clival chordomas, it is important that patients with this pathology are managed in high volume skull base centres where a multi-disciplinary team approach is available.
