Introduction: The sinking skin flap syndrome is a complication of decompressive craniectomies. The term sinking skin flap syndrome assumes that the herniation in this setting results from the combined effects of brain gravity and CSF depletion in patients who have undergone decompressive craniectomy [10, 11].

ST is also known as "sinking skin flap syndrome" and typically occurs in the weeks to months following operation. The characteristic phenomenon would be described as “the syndrome of the sinking skin flap, ” considering that neurological deterioration may be due solely to effect of concave deformity of the skin flap upon the underlying brain tissue. 4). Europe PMC is an archive of life sciences journal literature. Among many, sinking flap syndrome or syndrome of the trephined or paradoxical herniation of brain is frequently underestimated. This phenomenon may result from CSF hypovolemia, atmospheric pressure gradient that may be aggravated by CSF diversion, dehydration, and position change 4 , 7) . Five studies of TBI patients referred to the “syndrome of the trephined” or “sinking skin flap syndrome.

The syndrome of the sinking skin flap was introduced to explain neurological deterioration after decompressive craniectomy3. Besides, the traditional managements reducing the intracranial pressure for herniation may exacerbate paradoxical herniation, therefore, timely diagnosis and correct treatments are significantly important.
