Cranlein Operation

Krenlein operation

The Kroenlein operation is a surgical procedure developed by the Swiss surgeon Rudolf Kroenlein (1847-1910).

This operation is used to gain access to deep structures of the skull. In the Kroenlein procedure, the surgeon makes an incision in the scalp, removes part of the skull bones, and then displaces this bony “flap” to expose the brain or cranial nerves.

After carrying out the necessary manipulations, the surgeon returns the bone flap to its place and fixes it with metal plates and screws. The incision is then sutured.

The Kroenlein operation was developed at the end of the 19th century and became widespread for the treatment of brain tumors, aneurysms and other pathologies. It is still used in neurosurgery, despite the emergence of new minimally invasive techniques.
