Here, we demonstrate two cases of SSFS to emphasize the importance of timely diagnosis to avoid lethal sequelae of this phenomenon if not detected. DOI: 10. Although many theories have been put forward regarding development of SSFS, but commonly it is thought that there are. This results in displacement of the brain across various intracranial boundaries. The syndrome of the trephined (ST), also known as the “sinking skin flap syndrome”, is a disorder of delayed neurological deterioration . 7, 8 A detailed description of the four. One hypothesis has been that atrophy of the infarcted tissue leads to a decrease in the intracranial volume and subsequently a decrease in intracranial. See full list on radiopaedia.

Europe PMC is an archive of life sciences journal literature. 9) Following. The pathophysiology of this phenomenon is not completely clear, but is felt to be related to the conversion of a closed system to an open system. Its pathophysiology remains debatable, however cranioplasty may decrease the symptoms of SSFS by reducing the direct effect of atmospheric pressure on the brain and allowing the. Disabling neurologic deficits, as well as the impairment of overall mental status with the development of a concave deformity and relaxation of the skin flap, are frequently observed. Even less common is the development of SSFS following bone resorption after cranioplasty with exacerbation by.

By convention, ST refers to the development of those symptoms that are reversible after cranioplasty . The sinking skin flap syndrome is a rare complication after a large craniectomy. . The neurological status of the patient can occasionally be strongly related to posture. The syndrome of the sinking skin flap was introduced to explain neurological deterioration after decompressive craniectomy3. The shrinkage and displacement of the brain structure is caused by the differences in intracranial pressure and exter- nal atmospheric pressure. Sinking skin flap syndrome is a rare syndrome leading to increased intracranial pressure, known to neurosurgeons, yet uncommon and hardly ever reported in trauma patients.

It is defined as a neurological deterioration accompanied by a flat or concave. symptoms and imaging findings that may raise concern/constitute the syndrome are acute postoperative deterioration after hemicraniectomy with or without temporal association with external ventricular drainage or lumbar puncture. 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) . This phenomenon may result from CSF hypovolemia, atmospheric pressure gradient that may be aggravated by CSF diversion, dehydration, and position change1,4. ・広範な外減圧術後の稀な合併症. 2017.
