Sinking skin flap syndrome in the multi-trauma patient: a paradoxical management to TBI post craniectomy. Background: Sinking skin flap syndrome (SSFS) is an uncommon complication that can follow decompressive craniectomy. It results from the pressure difference between the atmospheric pressure and the intracranial pressure causing the brain to shift inward at the craniectomy site. The sinking skin flap syndrome is a complication of decompressive craniectomies. It is defined as a neurological deterioration accompanied by a flat or concave. 1. This avalanche of pathologic events may lead to neurologic worsening associated with a marked skin depression on the side of DC, which was introduced in 1977 as the “sinking skin flap syndrome” (SSFS).

As opposed to this, persistent brain herniation also occurs in patients after a decompressive craniectomy and a cerebrospinal fluid (CSF) drainage. Alteration in normal anatomy and pathophysiology can result in wide. The characteristic phenomenon would be described as “the syndrome of the sinking skin flap, ” considering that neurological deterioration may be due solely to effect of concave deformity of the skin flap upon the underlying brain tissue.

Spontaneous bone healing occurred in all the survived cases and completed several months after surgery due to the difference of age (Fig. Decompressive craniotomy. It occurs when atmospheric pressure exceeds intracranial pressure at the craniectomy defect. ST is characterised by the neurological changes associated with alteration of the pressure/volume relationship between intracranial pressure (ICP), volume of cerebrospinal fluid (CSF),. 2020; 2020 (06):a172. However, recurrent infection and sinking skin flap syndrome after cranioplasty remain cumbersome complications that require a well-planned reconstruction strategy. The sinking flap syndrome (SFS) is one of the complications of decompressive craniectomy (DC). 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. Sinking skin flap syndrome is defined as a series of neurologic symptoms with the skin depression at the site of cranial defect, which develop several weeks to months after large external cerebral decompression. Krupp et al. 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. The procedure is thought to convert cranium from a closed to an open box, hence altering the basic pathophysiology. Edema continued to progress, but edema and. The physiopathology of ST or SSFS may involve a number of factors. 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. (e) Intraoperative positioning of a contralateral external ventricular shunt was needed to reduce flap tension allowing uncomplicated re-suturing. DOI: 10. Hemorrhage infarction after a cranioplasty is a very rare complication with only 4 cases to date. ” 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. Sinking skin flap syndrome (SSFS) or “syndrome of the trephined” is a rare complication that can occur after decompressive craniectomy. Password. 9). At the other polar extreme, external brain tamponade occurs when subgaleal fluid accumulates under pressure and 'pushes' on the brain across the craniectomy defect. Introduction: 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. 55 Sakamoto S, Eguchi K, Kiura Y, Arita K, Kurisu K CT perfusion imaging in the syndrome of the sinking skin flap before and after cranioplasty. Right MCA Infarct 4. "Sinking skin flap syndrome" (SSFS) is defined as a secondary neurological deterioration in the presence of a sinking skin flap in patients with large craniectomies. 1. A 61-year-old male was. The subsequent neurological workup for TIA, including normal Duplex carotid vertebral ultrasound, was unremarkable. 2017. ”. The neurological status of the patient can occasionally be strongly related to posture. 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. We report two patients with traumatic subdural hemorrhage who had neur. Fig. Paradoxical brain herniation, also known as sinking skin flap syndrome or syndrome of the trephined, is a rare and potentially fatal complication of decompressive craniectomy. 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. The prevalence and characteristics of SSF syndrome after hemicraniectomy for malignant infarction of the. It is defined as a neurological deterioration accompanied by a flat or concave. It should be suspected in all patients who had skull surgery and present with new onset neurological deterioration and dysautonomic symptoms. It is characterized by the appearance of new neurological symptoms following the craniectomy, which are relieved after cranioplasty. 3. Abstract.
