Keyhole concept
Traditional large craniotomies have been the standard for aneurysm surgery. However, minimally invasive “keyhole” approaches have gained popularity for aneurysm clipping in recent years.
The keyhole concept in neurosurgery is designed to minimize the craniotomy needed for the access route to deep intracranial pathologies. Such keyhole surgeries cause less trauma and can be less invasive than conventional surgical techniques.
