Sinking skin flap syndrome or “syndrome of the trephined” is a rare complication after a large craniectomy, with a sunken skin above the bone defect with neurological symptoms such as severe headache, mental changes, focal deficits, or seizures. This results in displacement of the brain across various intracranial boundaries. The neuro-intensive care team should be prepared to diagnose and treat a spectrum of decompressive craniectomy complications including: cerebral contusions, infections, seizures, intra- and extra-axial hemorrhages and fluid collections, sinking skin flap syndrome or syndrome of the trephined, paradoxical herniation, and external brain. Clinical presentation May range from asymptomatic or mono symptomat. Remarkably, the brain parenchyma was more often still above. A 61-year-old male was. The case of a 28-year-old female with the sinking skin flap syndrome is reported together with the evaluation of cerebral blood flow using xenon computed tomography (CT). It is of relevance not only due to its frequency, it is often underdiagnosed, but also because of the possibility of reversing the symptoms with the proper treatment. His condition was complicated with ventilator associated pneumonia, and was treated with IV Fortum and Cefepime. A 56-year-old man developed sinking skin flap syndrome (SSFS) due to paradoxical uncal herniation during treatment with furosemide for congestive heart failure (CHF). Upright computed tomography (CT) before cranioplasty showed a remarkable shift of the brain compared to supine CT.

The syndrome of the sinking skin flap was introduced to explain neurological deterioration after decompressive craniectomy3. All studies were case reports and small case series. Sinking skin flap syndrome is a rare complication of decompressive craniectomy characterized by a sunken skin flap, neurological deterioration, and paradoxical herniation of the brain. 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) . 2 cm(2) versus 88. Background. Expand. It is thought to occur due to altered CSF dynamics secondary to high atmospheric pressure compared to intracranial pressure, similar in pathophysiology to paradoxical. To prevent complications following decompressive craniectomy (DC), such as sinking skin flap syndrome, studies suggested early cranioplasty (CP). 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. He had been continuously taking 75 mg of clopidogrel bisulfate daily after decompressive craniectomy for the acute cerebral infarction and discontinued the medication 7 days before cranioplasty. Cranioplasty using an original bone flap,. Most reports of SSFS were accompanied by CSF hypovolemic condition,. Introduction.

The syndrome describes a cluster of symptoms including depressed mood, headache, behavioral disturbance, and seizure related to cerebral cortex distortion under the skin flap once cerebral edema subsides. Sinking skin flap syndrome, resulting from decompressive craniectomy, is defined as a series of neurologic symptoms with skin depression at the site of cranial defect. Four days after his cranioplasty, follow-up CT images showed reversal of the midline shift with no significant complications in the underlying brain . However, it may result in sinking skin flap syndrome (SSFS) in some patients, for which cranioplasty is the only treatment option. 7. Sinking skin flap syndrome is a rare complication of decompressive craniectomy characterized by a sunken skin flap, neurological deterioration, and paradoxical herniation of the brain. In our study, patients with big cranial defects after decompressive hemicraniectomy and altered consciousness who underwent cranioplasty at <7 weeks or at 7–12 weeks fared.

After surgical decompression, the scalp may sink due to the lack of underlying bone to support the atmospheric pressure. reported on cases of trephine syndrome, as characterized by severe headaches, dizziness, pain, adverse effects of cranial defects, and depressive symptoms that improved after cranioplasty. Primary hemorrhages result from direct trauma, hypertension, coagulopathy, whereas secondary hemorrhages may result from descending transtentorial herniation from diverse etiologies. After that, sinking skin flap syndrome has been reported fairly in the literature. The mechanism underlying syndromic onset is poorly understood. The defect is usually covered over with a skin flap. This syndrome is associated with sensorimotor. It still remains a poorly understood and underestimated entity. Sinking skin flap syndrome is a craniectomy complication characterized by new neurological dysfunction that typically worsens in the upright position and improves. 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. 1. We present a.
