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. Syndrome of the trephined (ST) is a post-craniectomy complication. In addition to the external compressive effects on the brain which result from atmospheric pressure and gravitational forces, secondary effects including ischemia can occur as a result of altered cerebral perfusion. Sinking skin flap syndrome (SSFS) is a condition unique to patients who have undergone craniectomy [2]. The sinking flap syndrome (SFS) is one of the complications of decompressive craniectomy (DC).

The sinking skin flap syndrome is a set of neurological manifestations occurring weeks or even months after a large craniectomy performed for different reasons: severe head trauma as in the case. Grantham coined the term “the post traumatic syndrome” to describe similar subjective symptoms to that of “syndrome of the trephined. Sinking skin flap syndrome (SSFS) is a rare neurological complication in patients with traumatic haemorrhage, stroke or cerebral oedema who undergo decompressive craniectomy to relieve increased intracranial pressure. A craniectomy is a common neurosurgical procedure in which a portion of the skull is resected, but not put back (cf. Trephine (sinking skin flap) syndrome. Besides, the traditional managements reducing the intracranial pressure for herniation may exacerbate paradoxical herniation, therefore, timely diagnosis and correct treatments are significantly important. At the other polar extreme, external brain tamponade occurs when subgaleal fluid accumulates under pressure and 'pushes' on the brain across the craniectomy defect. His condition was complicated with ventilator associated pneumonia, and was treated with IV Fortum and Cefepime. The syndrome of the sinking skin flap was introduced to explain neurological deterioration after decompressive craniectomy3. A patient of sinking brain and skin flap syndrome.

On the basis of these data, we propose a classificationSinking skin flap syndrome, also known as syndrome of the trephined, occurs in decompressive craniectomy patients. The shrinkage and displacement of the brain structure is caused by the differences in intracranial pressure and exter- nal atmospheric pressure. The syndrome of the sinking skin flap was introduced to explain neurological deterioration after decompressive craniectomy3. The sinking skin flap syndrome may progress to "paradoxical herniation" as a consequence of the atmospheric pressure exceeding intracranial pressure and may eventually lead to coma and death 6).

We studied the clinical characteristics associated with complications in patients undergoing CP, with special emphasis on timing. 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.

A patient with a history of traumatic brain injury, status post bilateral craniectomies is admitted for skull reconstruction due to bilateral frontoparietal cranial defects. It is of relevance not only due to its frequency, it is often underdiagnosed, but also because of the possibility. Although her general condition stabilized within 7 months after the injury, the skin of the bilateral temporal regions was markedly depressed due to large bone defects. However, recurrent infection and sinking skin flap syndrome after cranioplasty remain cumbersome complications that require a well-planned reconstruction strategy. 19 Syndrome of Trephine • Sinking skin flap syndrome. Although frequently presenting with aspecific symptoms, that may be underestimated, it can lead to severe and progressive neurological deterioration and, if left untreated, even to death. Both autologous bone flaps and alloplastic substitutes have been surgically explored over time to achieve the pre-morbid contour and eliminate the existing and anticipated complications like the “Sinking flap Syndrome”. This phenomenon known as sinking skin flap syndrome or syndrome of trephined is a retroactive diagnosis rendered when a patient has reversal of postcraniectomy symptoms (described below) following cranioplasty. Eventually, in some cases, a significant difference between atmospheric and intra cranial. After removing the lumbar drainage, cerebrospinal fluid leakage occurred. • Caused by changes in the pressure gradient of intracranial pressure and atmospheric pressure.

The "sinking skin flap syndrome" (SSFS) is characterized by neurological symptoms (headache, epileptic seizures, vertigo, dysesthesias, or paresis) following extensive decompressive craniectomy which improve after cranioplasty. While the term ‘sinking skin flap syndrome’ has been used to describe neurologic symptoms related to scalp sinking and brain herniation after wide decompressive craniectomy, the terminology was not applicable to this case as it focuses mainly on the neurologic symptoms observed, rather than on wound problems [3,4,5].

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. It results from the pressure difference between the atmospheric pressure and the intracranial pressure causing the brain to shift inward at the craniectomy site.

It appears in the weeks or months (3 months in average) after the surgery and is characterized by a neurological deterioration, not explained by other etiologies. However, SSFS is reversible after cranioplasty [3], but infectious complications must be avoided after the procedure [4]. A diagnosis of syndrome of the trephined or “sinking skin flap syndrome were considered in them, and all of them improved after cranioplasty. Sinking skin flap syndrome, also known as “syndrome of the trephined,” is an uncommon complication after decompressive craniectomy. Without early identification and.

Conclusions. A late complication following craniectomy is the “sinking” of the skin flap over the surgical site, known as the “Sunken brain and Scalp Flap Syndrome”(SSFS) or “Motor Trephine Syndrome” (MTS) (Figure (Figure2A).

Three weeks later his flap had sunk in deeply and the skin was non-pinchable and he was noted to have headaches, vomiting and retching when he sat up. It results from the pressure difference between the atmospheric pressure and the intracranial pressure causing the brain to shift inward at the craniectomy site. Sinking Skin Flap Syndrome: Cause of Secondary Neurological Deterioration (PDF) Sinking Skin Flap Syndrome: Cause of Secondary Neurological Deterioration | RABII MOHAMED - Academia. An absent cranium allows for external compression via atmospheric pressure, causing alterations in cerebral blood flow, cerebral spinal fluid flow, and glucose. Sinking skin flap syndrome (SSFS) or “syndrome of the trephined” is an uncommon occurrence classically associated with decompressive craniectomy prior to cranioplasty [ 1, 2 ]. Five studies of TBI patients referred to the “syndrome of the trephined” or “sinking skin flap syndrome. Sinking skin flap syndrome, also known as “syndrome of the trephined,” is an uncommon complication after decompressive craniectomy. In 1939, Grant et al. We report our experience in a consecutive series of 43 patients. 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. The neurological status. Among many, sinking flap syndrome or syndrome of the trephined or paradoxical herniation of brain is frequently underestimated. The syndrome of the trephined was described in 1939 by Grant and Norcross and is defined as a progressive neurological deterioration after craniectomy. This kind of herniation with an uncommon mesencephalon compression is one of the most serious sinking skin flap syndrome (SSFS). 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. 1.

Sinking skin flap syndrome (SSFS) or “syndrome of the trephined” is an uncommon occurrence classically associated with decompressive craniectomy prior to cranioplasty [1, 2]. 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) . 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.
