Krause Sphenoid Punch — Neurosurgical-Origin Solo Pattern

Krause Sphenoid Punch — Solo Neurosurgical Pattern

The solo Krause sphenoid punch (distinct from the Krause-Voss combination covered in our ENT batch 10) is Fedor Krause’s original 1890s Berlin design for the transcranial approach to the sella turcica — the operation Harvey Cushing later modernised as the transsphenoidal approach. Krause’s original punch had a longer, finer bite than the later Krause-Voss combination, sized for the deep skull-base bone removal of the Berlin transcranial era.

Where the solo Krause earns its place

For the rare modern transcranial approach to the pituitary gland (used when a tumour has extended laterally into the cavernous sinus beyond the reach of the transsphenoidal endoscope), the solo Krause punch remains the right instrument for the bony skull-base work. The longer, finer bite reaches the cavernous-sinus medial wall that the standard Hajek family cannot access from below.

The Krause neurosurgical lineage

Krause trained alongside Trendelenburg in Berlin and his neurosurgical contributions — including the Krause approach to the cerebellopontine angle and his work on epilepsy surgery — defined turn-of-the-century German neurosurgery. The solo punch is one of the instruments that survives from that surgical era.
