What is the purpose of placing an Ivalon/Teflon pad in MVD procedures?

Placing an Ivalon or Teflon pad in microvascular decompression (MVD) procedures is primarily aimed at decreasing nerve irritation caused by surrounding vessels. In many cases, blood vessels can come into close contact with nerves, which may lead to compression and resultant neuropathy or pain, especially in situations like trigeminal neuralgia. The Ivalon/Teflon pad acts as a barrier, providing cushioning between the nerve and the vessel, thereby alleviating irritation and potentially reducing symptoms associated with nerve compression.

While other options may involve aspects of vascular health or nerve function, they do not align with the primary purpose of these pads in the context of MVD. Enhancing blood flow or promoting nerve regeneration, for example, are not the direct objectives of using Ivalon/Teflon pads, as their main role is to protect the nerve from mechanical irritation. Preventing vascular occlusion is also not relevant, since the concern is more about managing nerve-vessel interactions rather than occlusion itself.
