The sinking flap syndrome (SFS) is one of the complications of decompressive craniectomy (DC). ” In the presented case, these neurologic deficits may be a consequence of reduced cerebral blood flow 1 and a disturbed metabolism due to direct cortical compression of the sinking cranioplasty and the secondary diaschisis at different. 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. An absent cranium allows for external compression via atmospheric pressure, causing alterations in cerebral blood flow, cerebral spinal fluid. By convention, ST refers to the development of those symptoms that are reversible after cranioplasty . Although frequently presenting with aspecific symptoms, that may be. The syndrome of the trephined was described in 1939 by Grant and Norcross and is defined as a progressive neurological deterioration after craniectomy. 7 Classically, SSFS tends to occur in the upright position and to resolve in the Trendelenburg position, which could help to detach. “Syndrome of the trephined” or “sinking skin flap syndrome” is an unusual syndrome in which neurological deterioration occurs following removal of a large skull bone flap. 1.

Syndrome of the trephined (sinking skin flap syndrome) with and without paradoxical herniation: a series of case reports and review. This phenomenon may result from CSF hypovolemia, atmospheric pressure gradient that may be aggravated by CSF diversion, dehydration, and position change1,4. This results in displacement of the brain across various intracranial boundaries. It still remains a poorly understood and underestimated entity. Background: Syndrome of the trephined (ST) refers to the rare, reversible event of neurological deterioration following craniectomy. An absent cranium allows for external compression via atmospheric pressure, causing alterations in cerebral blood flow, cerebral spinal fluid flow, and glucose. Patient concerns: A 74-year-old man presented with traumatic subdural hematoma and underwent decompressive craniectomy. Although this association led to the development of new terminology for the syndrome (“sinking skin flap syndrome”), numerous findings in the literature indicate the existence of SoT in patients without sinking skin flap morphology. Background: Sinking skin flap syndrome (SSFS) is an uncommon complication that can follow decompressive craniectomy. Finding a concave scalp flap after decompressive craniotomy, particularly if the patient has been shunted, is not unusual. Once the computed tomography scan shows malignant cerebral swelling, the patient is expected to have a poor prognosis. • Caused by changes in the pressure gradient of intracranial pressure and atmospheric pressure. Retrospective analysis found that those patients with sinking skin flap syndrome had significantly smaller surface craniectomy, tended to be older in age, and had a larger infarct volume. Patients with SSF syndrome had a smaller surface of craniectomy (76. Also known by other names such as syndrome of the “trephined,” it consists of sunken skin above the bone defect along with neurological.

In the two cases presented here, however, large cranial defects after DC resulted in a sunken scalp with neurologic deterioration. It is of relevance not only due to its frequency, it is often underdiagnosed, but also because of the possibility. Upright computed tomography (CT) before cranioplasty showed a remarkable shift of the brain compared to supine CT. The syndrome of the trephined was introduced in 1939 as a feeling of tenderness, discomfort, and insecurity located at the site of craniectomy. (38%). .
