A DureT hemorrhage occurring during an episode of intracranial hypotension resulted in sinking skin flap syndrome which was responsible for acute paradoxal descending transtentorial herniation and Duret hemorrhage, 10 days after large hemicraniectomy which could indicate early cranioplasty. The main trouble in. Sinking skin flap syndrome and paradoxical herniation after hemicraniectomy for malignant hemispheric infarction. It should be suspected in all patients who had skull surgery and present with new onset neurological deterioration and dysautonomic symptoms. It results from the pressure difference between the atmospheric pressure and the intracranial pressure causing the brain to shift inward at the craniectomy site. 5 The development of symptoms is often insidious, but may be acute, and may be exacerbated by dehydration and patient positioning. doi: 10.

Teaching point: Sinking skin flap syndrome is a medical emergency that rarely complicates large craniectomy. Patients with the classical “Motor trephine syndrome/ Sinking skin flap syndrome” following large craniectomy defects, may hugely benefit from an early cranioplasty procedure, with a reversal of features of this syndrome and early recovery of their neurological and cognitive functions. We studied the clinical characteristics associated with complications in patients undergoing CP, with special emphasis on timing. Conclusion: Causes of cerebral edema and hemorrhage immediately after cranioplasty include reperfusion, reduction of automatic adjustment function, sinking skin flap syndrome, negative pressure due to s. 3. Management is largely conservative. In addition to the cosmetic and protective roles, cranioplasty also has a definite therapeutic role by reversing the sensorimotor deficits and neurological deterioration that often accompanies large cranial defects, a condition commonly referred to as the ‘Motor Trephine Syndrome’ (MTS) or ‘Sinking Skin Flap syndrome’(SSFS) . back in 1977.

Sinking skin flap syndrome with delayed motor deficits, or "motor trephine syndrome" is not well known in patients with large skull defects, where progressive neurological deterioration is associated with the sinking skin flap[4, 12]. Besides, the traditional managements reducing the intracranial pressure for herniation may exacerbate paradoxical herniation, therefore, timely diagnosis and correct treatments are significantly important. BACKGROUND AND PURPOSE "Sinking skin flap" (SSF) syndrome is a rare complication after large craniectomy that may progress to "paradoxical" herniation as a consequence of atmospheric pressure exceeding intracranial pressure.

This can lead to paradoxical herniation and the sinking skin flap syndrome, also called the syndrome of the trephined. It is defined as a neurological deterioration accompanied by a flat or concave. Sinking skin flap syndrome (SSFS) is a rare complication following large craniectomy and usually manifests as mental state decline, severe headache, seizures or focal deficits after a relatively stable and improved stage.

Also known by other names such as syndrome of the “trephined,” it consists of sunken skin above the bone defect along with neurological. This phenomenon may result from CSF hypovolemia, atmospheric pressure gradient that may be aggravated by CSF diversion, dehydration, and position change 4, 7).
