His condition was generally improved. The syndrome has also been called the “syndrome of the sinking skin flap” by Yamaura and Makino. 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. Even less common is the development of SSFS following bone resorption after cranioplasty with exacerbation by a ventriculoperitoneal (VP) shunt. Han PY, Kim JH, Kang HI, Kim JS.

We present a patient with sinking skin flap syndrome that underwent such a procedure and subsequently experienced immediate postoperative ascending transtentorial herniation and intracranial hemorrhage remote from the surgical site. Yet, no difference was found with regard to surgical revision, and sinking skin flap syndrome did not lead to earlier CP in our cohort. 3. The “Motor Trephine Syndrome (MTS)” also known as the “Sunken brain and Scalp Flap Syndrome” or the “Sinking Skin Flap Syndrome (SSFS)” or the “Syndrome of the trephined” is an unusual syndrome in which neurological deterioration occurs following removal of a large skull bone flap. The shrinkage and displacement of the brain structure is caused by the differences in intracranial pressure and exter- nal atmospheric pressure. Alteration in normal anatomy and pathophysiology can result in wide variety of symptoms including altered mental status, hemodynamic instability, and dysautonomias. 2021, Anesthesia and Critical Care.

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. Although changes in cerebrospinal fluid (CSF) hydrodynamics, cerebral blood flow and brain metabolism have been described as partial aspects of the pathophysiology, a. However, SSFS is reversible after cranioplasty [3], but infectious complications must be avoided after the procedure [4]. We considered that the cause of brain edema and cerebral hemorrhage immediately after cranioplasty could be from reperfusion, the deterioration of autoregulation, SSFS, negative pressure by subgaleal drain, venous stasis, vascular damage because of.

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. and seizure related to cerebral cortex distortion under the skin flap once cerebral edema subsides. This usually. Gadde, J, Dross, P, Spina, M. The sinking skin flap syndrome (SSFS) is defined as a secondary neurological deterioration which cannot be attributed to the primary illness and which occurs in the presence of a sinking skin flap in patients with large craniectomies. Decompressive craniotomy. he syndrome of the “trephined” or the “sinking skin flap” (SSF) syndrome is a rare complication after a large skull bone defect. Cases Reports: The first case is a 55 year old man. 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 References [1] Timofeev I, Hutchinson PJ (2006) Outcome after surgical decompression of severe traumatic brain injury. The sinking skin flap syndrome (SSFS), or syndrome of the trephined, is a pathological condition arising from the presence of large bone defects of the skull. This syndrome comprises a wide spectrum of neurological symptoms including delay in neurological progression, motor symptoms, cognitive decline, impaired vigilance, and headaches [ 26 ]. A typical CT finding in a patient with a sinking skin flap syndrome. (e) Intraoperative positioning of a contralateral external ventricular shunt was needed to reduce flap tension allowing uncomplicated re-suturing. It consists of a sunken skin above the bone defect with neurological symptoms such as severe headache, mental. 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. No. 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. It is defined as a neurological deterioration accompanied by a flat or concave. Complications following craniotomy are not uncommon and Sinking Skin Flap Syndrome (SSFS) constitutes a rare entity that may present after a large. Complications following craniotomy are not uncommon and Sinking Skin Flap Syndrome (SSFS) constitutes a rare entity that may present after a large Decompressive Craniectomy. Clinical and radiological features (DC diameter, shape of craniectomy. 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. We report a unique case presenting with these complications immediately after decompressive craniectomy for severe traumatic brain injury. The radiologist must be vigilant regarding the appearance of. severe headache, tinnitus, dizziness, undue fatigability or vague discomfort at the site of the bone defect, a feeling of apprehension and insecurity, mental. 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. A 61-year-old male was. Although changes in cerebrospinal fluid (CSF) hydrodynamics, cerebral blood flow and brain metabolism have. Knowing that the mechanism of SSSF has been speculated to be the result of the. This phenomenon may result from CSF hypovolemia, atmospheric pressure gradient that may be aggravated by CSF diversion, dehydration, and position change 4 , 7) . 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). Clinicians need to be aware of sinking skin flap syndrome and to look for abnormal neurological developments in patients with craniectomy in order to avoid unnecessary testing and to prevent its occurrence. 39. The sinking skin flap syndrome (SSFS) or syndrome of the trephined is a rare complication that occurs in approximately 10% of large craniectomies and tends to develop several weeks to several months after surgery. We considered that the cause of brain edema and cerebral hemorrhage immediately after cranioplasty could be from reperfusion, the deterioration of autoregulation, SSFS, negative pressure by subgaleal drain, venous stasis, vascular damage because of. ”. ”. In a hospitalized trauma patient with declining neurological status, rarely do we encounter further deterioration by elevating the patients’ head, diuresis and. We report two patients with traumatic subdural hemorrhage who had neur. However, there is a widely variable onset, with cases reported as early as days after surgery and as distant as decades later . CT perfusion imaging in the syndrome of the sinking skin flap before and after cranioplasty [Case Reports]. The “Motor Trephine Syndrome (MTS)” also known as the “Sunken brain and Scalp Flap Syndrome” or the “Sinking Skin Flap Syndrome (SSFS)” or the “Syndrome of the trephined” is an unusual syndrome in which neurological deterioration occurs following removal of a large skull bone flap. “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. Once the computed tomography scan shows malignant cerebral swelling, the patient is expected to have a poor prognosis. Korean J Neurotrauma. 4. Disabling neurologic deficits, as well as the impairment of overall mental status with the development of a concave deformity and relaxation of the skin flap, are frequently observed. Trephine syndrome, also known as the sinking skin flap syndrome, is a relatively late complication in post-craniectomy patients. The sinking skin flap syndrome (SSFS) or syndrome of the trephined is a rare complication that occurs in approximately 10% of large craniectomies and tends to develop several weeks to several months after surgery. Although frequently presenting with aspecific symptoms, that may be. ・SSFSとは？. This usually. This condition involves sinking of the scalp on the decompressed side deep beyond the edges of the bone defect.
