Dynamic Craniotomy™
A New Paradigm in Cranial Surgery
A cranial fixation system designed to accommodate postoperative brain swelling while preserving the native bone flap.
Key Benefits
✔ Allows controlled outward bone flap movement during swelling
✔ Helps avoid decompressive craniectomy in selected cases
✔ Bone flap returns to anatomical position as swelling resolves
Craniotomy
Large bone flap with temporal craniectomy
Expansile Duroplasty
Bone flap removed and pathology addressed.
Expansile durotomy with duroplasty.
Dynamic Fixation
NuCrani plates fix the bone flap.
Swelling Accommodation
Bone flap elevates outward with cerebral swelling.
Automatic Reversal
Bone flap returns to flush position after swelling resolves.
Bone Flap Fixation
Khanna Dynamic NuCrani plates placed over the craniotomy burr holes fixate the bone flap and prevent bone flap sinking
Cranial Decompression
Increase in intracranial pressure from brain swelling or intracranial hemorrhage exerts pressure on the bone flap which migrates outwards enabled by the reversibly expandable NuCrani dynamic plates and increases intracranial volume
Dynamic Craniotomy
A: Craniotomy with bone flap removal.
B: Durotomy with dural expansive patch grafting. C: Fixation of bone flap with dynamic plates. D: Bone flap elevation to accommodate an increase in intracranial volume from brain swelling and/or intracranial hemorrhage. E: Retraction of bone flap in anatomic flush position after resolution of brain swelling.
