A tentorial sling in microvascular decompression for trigeminal neuralgia - Technical note

The key to the successful microvascular decompression of the trigeminal nerve is the maintenance of the separation between the trigeminal nerve and the offending vessel. The authors describe a technique whereby a dural sling is fashioned from the tentorium cerebelli (the anatomy of which is briefly reviewed), which is used to suspend the vessel away from the nerve and is secured by a single hemoclip.
