Sinking Skin Flap Syndrome/Sydrome of trephinad
- History of previous cranioectomy.
– forces of atmospheric pressure and gravity overwhelm intracranial pressure causing herniation of brain
– CSF hypovolemia and reduction of cerebral blood flow
– Orthostatic positioning has been described to exacerbate the condition.
– Non specific neurologic symptoms eg dizziness, memory loss, tinnitus
– Psychiatric symptoms
– Focal deficits, autonomic symptoms
- Dx: CT scan is typical (prior craniectomy with mass effect)
- Treatment: early cranioplasty results in normalization of the underlying pressure imbalance and recovery of neurologic function.
