The syndrome of the trephined (ST), also known as the “sinking skin flap syndrome”, is a disorder of delayed neurological deterioration . Postoperatively, strict follow-up and early cranioplasty are warranted . 4 vs 9. Although changes in cerebrospinal fluid (CSF) hydrodynamics, cerebral blood flow and brain metabolism have been described as partial aspects of the pathophysiology, a. It consists of a sunken skin above the bone defect with neurological symptoms such as severe headache, mental. 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. ・1997年Yamamuraらによって報告. ” 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. Complications following craniotomy are not uncommon and Sinking Skin Flap Syndrome (SSFS) constitutes a rare entity that may present after a large Decompressive Craniectomy. The primary goals of cranioplasty after DC are to protect the brain, achieve a natural appearance and prevent sinking skin flap syndrome (or syndrome of the trephined). Secondary Effects of CNS Trauma. This phenomenon may result from CSF hypovolemia, atmospheric pressure gradient that may be aggravated by CSF diversion, dehydration, and position change1,4. A 77-year-old male patient with an acute subdural hematoma was treated using a. It is defined as a neurological deterioration accompanied by a flat or concave.

In a study of 108 patients performed back in 2008 who underwent decompressive crainectomy, syndrome of trephined was reported in 13% of patients between 28 and. Besides, the traditional managements reducing the intracranial pressure for herniation may exacerbate paradoxical herniation, therefore, timely diagnosis and correct treatments are significantly important. Following an inner ellipse of the previous DC-surgery scar could contribute in most cases to the preservation of the vascular perfusion even if an incision outside of the ellipse might be needed in certain settings such as sinking skin flap syndrome (SSFS). the syndrome’s characteristics. 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[. The neurological status of the patient can occasionally be strongly related to posture. He was diagnosed with sinking skin flap syndrome consistent with altered mental status and a sunken skin flap with increased midline shift. Results. We report two patients with traumatic subdural hemorrhage who had neur. Alteration in normal anatomy and pathophysiology can result in wide. Even less common is the development of SSFS. Taste disorders. It results from the pressure difference between the atmospheric pressure and the intracranial pressure causing the brain to shift inward at the craniectomy site. However, SSFS is reversible after cranioplasty [3], but infectious complications must be avoided after the procedure [4]. Background: The sinking skin syndrome (SSS) is a particular complication after a decompressive craniectomy (DC). 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. Independent of the consequences of the original aetiology that necessitated the craniectomy, the bone defect alone may be the cause of the symptoms, called 'trephined syndrome' or 'sinking skin flap s 1. sinking skin flap syndrome (aka, syndrome of the trephined) Basics: This usually occurs several months postoperatively. 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. One hypothesis has been that atrophy of the infarcted tissue leads to a decrease in the intracranial volume and subsequently a decrease in intracranial. 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. 2015. ・感染.

Case report: A 53-year-old female sustained a severe head injury. Therefore, it is important to. Sinking skin flap syndrome is typically a late post-craniectomy complication, most often occurring between 1 month and 1 year after surgery. This may result in subfalcine and/or transtentorial herniation. The subsequent neurological workup for TIA, including normal Duplex carotid vertebral ultrasound, was unremarkable. 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”. The case of a 28-year-old female with the sinking skin flap syndrome is reported together with the evaluation of cerebral blood flow.
