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). Objective To prevent complications following decompressive craniectomy (DC), such as sinking skin flap syndrome, studies suggested early cranioplasty (CP). SSFS was first reported in 1997 by Yamamura et al who calls it a series of neurologic symptoms and signs with skin depression at the site of craniectomy. Diagnosis In 1977 Yamura and Makino coined the term “syndrome of the sunken skin flap” to describe the neurological symptoms due to a craniectomy defect, and early cranioplasty has been recommended. 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. As opposed to this, persistent brain herniation also occurs in patients after a decompressive craniectomy and a cerebrospinal fluid (CSF) drainage. It results from the pressure difference between the atmospheric pressure and the intracranial pressure causing the brain to shift inward at the craniectomy site. He was diagnosed with sinking skin flap syndrome consistent with altered mental status and a sunken skin flap with increased midline shift. [Europe PMC free article] [Google Scholar] 4. We studied the clinical characteristics associated with complications in patients undergoing CP, with special emphasis on timing. Even less common is the development of SSFS.

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. Therefore, in a patient with decompressive craniectomy, lumbar drainage or shunt surgery carries a risk to cause sinking skin flap syndrome (SSFS) or trephined syndrome, progressing to paradoxical. It occurs when atmospheric pressure exceeds intracranial pressure at the craniectomy defect.

The symptoms following large craniectomy were reported to described the "syndrome of the trephined (ST)"or "sinking skin flap syndrome (SSFS)" 13, 27, 30), while Gardner (1945) 12) reported clinical improvement after cranioplasty with tantalum repair. However, SSFS is reversible after cranioplasty [3], but infectious complications must be avoided after the procedure [4]. Hallmark of SSFS is the sinking of the scalp to a plane lower than the edges of the skull defect in the setting of neurological. It is thought to occur due to altered CSF dynamics secondary to high atmospheric pressure compared to intracranial pressure, similar in pathophysiology to paradoxical. All clinicians must be aware of this rare yet life threatening syndrome in.

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). Upright computed tomography (CT) before cranioplasty showed a. Lastly, reconstruction of the dura defect and dead space with a musculocutaneous flap creates a large donor site defect.

Sinking skin flap syndrome, paradoxical herniation (more on these below). Yet, no difference was found with regard to surgical revision, and sinking skin flap syndrome did not lead to earlier CP in our cohort. Sinking skin flap syndrome (SSFS), or syndrome of the trephined (ST), is characterized by the development of new neurological symptoms following decompressive craniectomy (e. Sinking skin flap syndrome (SSFS) or paradoxical herniation (PH) is a rare complication and sporadically occurs in patients after DC. Taste disorders. 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. 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. Background: Syndrome of the trephined (ST) refers to the rare, reversible event of neurological deterioration following craniectomy. PDF. Sinking skin flap syndrome is a rare syndrome leading to increased intracranial pressure, known to neurosurgeons, yet uncommon and hardly ever reported in trauma patients. Teaching point: Sinking skin flap syndrome is a medical emergency that rarely complicates large craniectomy. Sinking skin flap syndrome (SSFS) is an uncommon complication that can follow decompressive craniectomy. We studied the clinical characteristics associated with complications in patients undergoing CP, with. "Syndrome of the trephined" or "sinking skin flap syndrome" is an unusual syndrome in which neurological deterioration occurs following removal of a large skull bone flap. 5 The development of symptoms is often insidious, but may be acute, and may be exacerbated. Fig. Disabling neurologic deficits, as well as the impairment of. MTS is. Sinking skin flap syndrome is a rare and potentially fatal complication of a decompressive craniectomy. Although changes in cerebrospinal fluid (CSF) hydrodynamics, cerebral blood flow and brain metabolism have. should be considered in the differential. The syndrome has also been called the “syndrome of the sinking skin flap” by Yamaura and Makino. However, SSFS is reversible after cranioplasty [3], but infectious complications must be avoided after the procedure [4]. ・外減圧後の合併症. INTRODUCTION. Nonetheless, full healing of the skin flap was evidentSinking Skin Flap Syndrome. The 2024 edition of ICD-10-CM M95. 127. 2021, Anesthesia and Critical Care. The sinking flap syndrome (SFS) is one of the complications of decompressive craniectomy (DC). 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. (e) Intraoperative positioning of a contralateral external ventricular shunt was needed to reduce flap tension allowing uncomplicated re-suturing. Management is largely conservative. Sinking skin flap syndrome (SSFS) is a condition unique to patients who have undergone craniectomy [2]. It seems logical that longer times-to-cranioplasty would promote the neurologic compromise associated with the syndrome of the sinking skin flap [4, 11, 13, 14]. PMID: 26906112. It occurs when atmospheric pressure exceeds intracranial pressure at the craniectomy defect. It occurs from several weeks to months after decompressive craniectomy (DC). 8) In 1977, Yamaura et al. A 61-year-old male was hospitalized with high fever and operative site swelling. Even less common is the development of SSFS following bone resorption after. ・頭蓋内外の血腫、液体貯留. Schorl, M. 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. Most reports of SSFS were accompanied by CSF hypovolemic condition,. Sinking skin flap syndrome, also known as “syndrome of the trephined,” is an uncommon complication after decompressive craniectomy. In 1939, Grant and Norcross defined the ‘syndrome of the We used the search terms ‘trephined syndrome’, ‘syndrome trephined’ by a cluster of symptoms that included ‘dizziness, of the trephined’, ‘Sinking skin flap’, and ‘sinking skin flap syn-undue fatigability, vague discomfort at the site of the defect, drome’. This syndrome is associated with. 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.
