NEUROVASCULAR COMPRESSION
MICROVASCULAR DECOMPRESSION
Microvascular decompression as an surgical method aims to remove a so-called neurovascular compression. Under micro-surgical conditions, the affected cranial nerve is demonstrated in the posterior cranial fossa and the contact between the vascular loop and the root entry zone of the cranial nerve at the brain stem is identified. The blood vessel is then carefully removed from the nerve and slightly displaced, as not to interrupt the blood supply. In order to prevent the vessel from falling back into its former position, the contact area is padded with Teflon. Access to the nerves in the posterior cranial fossa is performed through a small (approx. 2-3 cm) opening in the skull behind the ear. Microvascular decompression is introduced by Jannetta and is an established method and presents the causal treatment for neurovascular compression syndromes. In contrast to destructive surgical methods, where there is a high risk of function loss of the cranial nerve, in the majority of the cases where microvascular decompression is performed, a successful and permanent treatment of the respective entity is achieved. Beside the general risks associated with an operation (i.e. anaesthesia, infection, bleeding, etc.) it is important to mention that the risk of hearing difficulty or loss is in 1% of the operations. In order to not only ensure surgery that is as safe as possible for the patient, but also to avoid possible loss of neurological function, the operation is accompanied in all its phases by modern monitoring methods for the neurological functions.

	Principle of microvascular decompression
	Microsurgical view into the posterior fossa dor microvascular decompression. Identification of the trigeminal nerve and a vessel compressibg the nerve close to the brainstem.
	Clear contact between the trigeminal nerve and the vessel (A. cerebelli superior).
	After dissection of the arachnoid neurovascular compression on the nerven it clearly visible.
	Mobilisation of the vascular loop from the nerve.
	Positioning of Teflon
	Complete mikrovascular decompression of the nerve. A new contacting is impossible now.
