Disabling neurologic. 1 a and b). ” 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. he syndrome of the “trephined” or the “sinking skin flap” (SSF) syndrome is a rare complication after a large skull bone defect. Abstract. It results from an intracerebral hypotension and requires the replacement of the cranial flap. Case report: A 53-year-old female sustained a severe head injury. Sinking Skin Flap Syndrome, a Rare Complication of Craniectomy J Belg Soc Radiol. The syndrome of the “trephined” or the “sinking skin flap” (SSF) syndrome is a rare complication after a large skull bone defect. Sinking skin flap syndrome is a delayed complication of a decompressive craniectomy. ・頭蓋内外の血腫、液体貯留. Grantham coined the term “the post traumatic syndrome” to describe similar subjective symptoms to that of “syndrome of the trephined. 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. The sinking flap syndrome (SFS) is one of the complications of decompressive craniectomy (DC). 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). The syndrome of the sinking skin flap was introduced to explain neurological deterioration after decompressive craniectomy3. Knowing that the mechanism of SSSF has been speculated to be the result of the. In the two cases presented here, however, large cranial defects after DC resulted in a sunken scalp with neurologic deterioration. 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. Clinical presentation May range from asymptomatic or mono symptomat. Sinking skin flap syndrome and paradoxical herniation after hemicraniectomy for malignant hemispheric infarction. Europe PMC is an archive of life sciences journal literature. Aphasia precipitated by adoption of erect posture was the uncommon and easily identifiable neurological finding in this patient that drew our attention to the fact that he might be having the “sinking scalp flap syndrome. In the present case, sensorimotor paresis promptly reversed after cranioplastic repair and MR brain perfusion. 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. The neurological status. In patient with sinking. Sinking Skin Flap Syndrome . An absent cranium allows for external compression via atmospheric pressure, causing alterations in cerebral blood flow, cerebral spinal fluid. Spontaneous bone healing occurred in all the survived cases and completed several months after surgery due to the difference of age (Fig. marked concavity at the craniotomy site accompanied by subfalcine and/or transtentorial herniationSinking skin flap syndrome is a craniectomy complication characterized by new neurological dysfunction that typically worsens in the upright position and improves after cranioplasty. The physiopathology of ST or SSFS may involve a number of factors. A 61-year-old male was. Although cranioplasty itself is a. 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. 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). Admitted with Glascow score of 13/15, rapid neurological deterioration was noted with a GCS of 9/15, and then. Europe PMC is an archive of life sciences journal literature. 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. It occurs when atmospheric pressure exceeds intracranial pressure at the craniectomy defect. Teaching point: Sinking skin flap syndrome is a medical emergency that rarely complicates large craniectomy. 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. 2020; 2020 (06):a172. Initial series of patients with this syndrome were small, to. The syndrome of the sinking skin flap (SSSF) with delayed sensorimotor deficits after craniectomy is not well known and often neglected. 沈没皮膚フラップ症候群（SSFS）、またはトレフィン酸症の症候群は、頭蓋骨の大きな骨欠損の存在から生じる病的状態です。. Decompressive craniectomy (DC) is commonly performed in patients with intracranial hypertension or brain edema due to traumatic brain injury. 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 consists of a sunken skin above the bone defect with neurological symptoms such as severe headache, mental changes, focal deficits, or seizures. Case presentation • Young male patient , 32 years old • He had Right MCA territory infract 3. Cases Reports: The first case is a 55 year old man. Although many theories have been put forward regarding development of SSFS, but commonly it is thought that there are. Complications following craniotomy are not uncommon and Sinking Skin Flap Syndrome (SSFS) constitutes a rare entity that may present after a large Decompressive Hemicraniectomy (DC) [ 1 ]. Sinking skin flap syndrome, also known as “syndrome of the trephined,” is an uncommon complication after decompressive craniectomy. Although it is very rare, sinking skin flap syndrome may lead to paradoxical brain herniation. As opposed to this, persistent brain herniation also occurs in patients after a decompressive craniectomy and a cerebrospinal fluid (CSF) drainage. Although it is very rare, sinking skin flap syndrome may lead to paradoxical brain.
