This phenomenon may result from CSF hypovolemia, atmospheric pressure gradient that may be aggravated by CSF diversion, dehydration, and position change1,4. Crossref, Medline, Google ScholarObjectives Syndrome of the Trephined (SoT) or sinking skin flap syndrome is characterised by neurological deterioration occurring after a delay post-craniectomy, with or without a significant postural component, that may improve with cranioplasty. SUNKEN SKIN FLAP SYNDROME : a case presentation and review Dr Bipin Bhimani Well Care Hospital Rajkot 2. Introduction: The sinking skin flap syndrome is a complication of decompressive craniectomies. These 2 syndromes illustrate the paradigm shift of the indications for cranioplasty, which have evolved from cosmetic. The mechanism underlying syndromic onset is poorly understood. It is characterized by the appearance of new neurological symptoms following the craniectomy, which are relieved after cranioplasty. Sinking skin flap syndrome is defined as neurologic deficits with concave deformity and relaxation of the skin flap which tends to develop several weeks to months after large craniectomy [ 7 ]. It is defined as a neurological deterioration accompanied by a flat or concave. 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. Sinking skin flap syndrome (SSFS) or "syndrome of the trephined" is a rare complication that can occur after decompressive craniectomy. 1 It consists of a sunken skin above the bone defect with neurological symptoms such as severe headaches, mental changes, focal deficits, or seizures.

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. In patient with sinking skin flap syndrome, cerebral blood flow and cerebral metabolism are decreased by. "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. Fig. The neurological status of the patient can occasionally be strongly related to posture. 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. We report a unique case presenting with these complications immediately after decompressive craniectomy for severe traumatic brain injury. At the other polar extreme, external brain tamponade occurs when subgaleal fluid accumulates under pressure and 'pushes' on the brain across the craniectomy defect. 1 A–D). CSF leak. 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). Sinking skin flap syndrome (SSFS) is a rare complication following large craniectomy and usually manifests as mental state decline, severe headache, seizures or focal deficits after a relatively stable and improved stage. Sinking skin flap syndrome and vacuum suction drain may be the main risks of a postoperative venous congestion and stasis, which may result in diffuse cerebral swelling. The 2024 edition of ICD-10-CM M95. This syndrome is associated with sensorimotor.

Sinking skin flap syndrome is a catastrophic delayed complication in patients who underwent craniectomy for various reasons. We report our experience in a consecutive series of 43 patients diagnosed with SFS and propose a classification. An absent cranium allows for external compression via atmospheric pressure, causing alterations in cerebral blood flow, cerebral spinal fluid. The syndrome of the sinking skin flap was introduced to explain neurological deterioration after decompressive craniectomy 15). Background: Syndrome of the trephined (ST) refers to the rare, reversible event of neurological deterioration following craniectomy. We also evaluated the risk factors for the incidence of SSFS in DC patients with LD. 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. Clin Neurol Neurosurg 2006;108(6):583–585. However, several groups reported higher complication rates in early CP. No. As opposed to this, persistent brain herniation also occurs in patients after a decompressive craniectomy and a cerebrospinal fluid (CSF) drainage.

We present a 33-year-old man who experienced hemiparesis in the upright position after craniectomy. 7 Classically, SSFS tends to occur in the upright position and to resolve in the Trendelenburg position, which could help to detach. Among many, sinking flap syndrome or syndrome of the trephined or paradoxical herniation of brain is frequently underestimated. Sinking skin flap syndrome, also known as “syndrome of the trephined,” is an uncommon complication after decompressive craniectomy. The patient then underwent cranioplasty using an autologous bone graft. ” 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. 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). We experienced neurological improvement in a patient with markedly sunken craniectomy site after ventriculoperitoneal shunt (V-P shunt) clamping operation. 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.

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. Sinking skin flap syndrome in the multi-trauma patient: a paradoxical management to TBI post craniectomy. This can lead to paradoxical herniation and the sinking skin flap syndrome, also called the syndrome of the trephined. In the two cases presented here, however, large cranial defects after DC resulted in a sunken scalp with neurologic deterioration. ST is also known as “sinking skin flap syndrome” and typically occurs in the weeks to months following operation. Sinking skin flap syndrome with delayed motor deficits, or "motor trephine syndrome" is not well known in patients with large skull defects, where progressive neurological deterioration is associated with the sinking skin flap[4, 12]. This sinking skin flap syndrome may develop when the fascia and flap directly come into contact with the cranial parenchyma. 1007/s00234-016-1651-8.

As for our patient group, we were not able to identify risk factors for neither the external brain herniation nor the sinking skin flap syndrome. Alteration in normal anatomy and pathophysiology can result in wide variety of symptoms including altered mental status, hemodynamic instability, and dysautonomias. The problem was considered to have been asymptomatic sinking skin flap syndrome (SSFS). Commonly, it is associated with sinking of the skin near the bone-free area. The shrinkage and displacement of the brain structure is caused by the differences in intracranial pressure and exter- nal atmospheric pressure. Syndrome of the trephined (ST), also termed “sinking skin flap syndrome” and “paradoxical brain herniation,” describes the reversible event of neurological deterioration following craniectomy, typically within the weeks to months following the operation [1]. 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.

The search yielded 19 articles with a total of 26 patients. The mechanism underlying syndromic onset is poorly understood. Zusammenfassung. This may result in subfalcine and/or transtentorial herniation. Lumbar drainage was performed; however, sinking skin flap syndrome was observed. Edema continued to progress, but edema and. 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. 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). 1. Syndrome of the Trephined (SOT) or sinking skin flap syndrome is a known but rare complication following large craniectomy. Upright computed tomography (CT) before cranioplasty showed a. • 22/9/13 - moderate size infarct , thrombolysed with IV tPA 5. This can present with either nonspecific symptoms. He had been continuously taking 75 mg of clopidogrel bisulfate daily after decompressive craniectomy for the acute cerebral infarction and discontinued the medication 7 days before cranioplasty. [ 4] Initial series of patients with this syndrome. Decompressive craniectomy (DC) is commonly performed in patients with intracranial hypertension or brain edema due to traumatic brain injury. Upright computed tomography (CT) before cranioplasty. The sinking flap syndrome (SFS) is one of the complications of decompressive craniectomy (DC). The sinking skin flap syndrome is a rare complication after a large craniectomy. in the following article: Paradoxical brain herniation - “ Paradoxical brain herniation, also known as sinking skin flap syndrome or syndrome of the trephined, is a rare and potentially fatal complication. 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. The syndrome of the sinking skin flap was introduced to explain neurological deterioration after decompressive craniectomy 15). The neurosurgery service subsequently. Abstract. 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. The aim of the procedure was to improve cosmesis and protect the brain and avoid sinking skin flap syndrome which is a rare complication of decompressive craniectomy characterized by a sunken skin flap, neurological deterioration, and paradoxical herniation of the brain. Although changes in cerebrospinal fluid (CSF) hydrodynamics, cerebral blood flow and brain metabolism have been described as partial aspects of the pathophysiology, a. We report our experience in a consecutive series of 43 patients. Although cranioplasty itself is a. As the herniated brain tissue recedes, the skin flap from the surgical site can become sunken. Krupp et al. 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”. This can present with either nonspecific symptoms. Among various postulated causes, there is evidence that. Although changes in cerebrospinal fluid (CSF) hydrodynamics, cerebral blood flow and brain metabolism have been described as partial aspects of the pathophysiology, a. Sinking skin flap syndrome (SSFS) is a rare neurological complication in patients with traumatic haemorrhage, stroke or cerebral oedema who undergo decompressive craniectomy to relieve increased intracranial pressure. A DureT hemorrhage occurring during an episode of intracranial hypotension resulted in sinking skin flap syndrome which was responsible for acute paradoxal descending transtentorial herniation and Duret hemorrhage, 10 days after large hemicraniectomy which could indicate early cranioplasty. The neurological status. Die rekonstruktiven operativen Verfahren nach Schädel-Hirn-Trauma umfassen Kranioplastiken mit autologem Kalottenstück, CAD-gefertigtem Implantat oder Polymethylmethacrylat (PMMA)-Implantat sowie Rekonstruktionen von Schädeldach und Schädelbasis mit Osteosynthesematerial aus Titan. Sinking skin flap syndrome is defined as neurologic deficits with concave deformity and relaxation of the skin flap which tends to develop several weeks to. The sinking skin flap syndrome represents a less-frequent complication in patients after a decompressive craniectomy. Although changes in cerebrospinal fluid (CSF) hydrodynamics, cerebral blood flow and brain metabolism have been. 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. 1 It consists of a sunken skin above the bone defect with neurological symptoms such as severe headaches, mental changes, focal deficits, or seizures. In a hospitalized trauma patient with declining neurological status, rarely do we encounter further deterioration by elevating the patients’ head, diuresis and. While the term ‘sinking skin flap syndrome’ has been used to describe neurologic symptoms related to scalp sinking and brain herniation after wide decompressive craniectomy, the terminology was not applicable to this case as it focuses mainly on the neurologic symptoms observed, rather than on wound problems [3,4,5]. The prevalence and characteristics of SSF syndrome after hemicraniectomy for malignant infarction of the middle cerebral. described similar symptoms that improved with cranioplasty as the sinking skin flap syndrome. 1: (A – C) Axial CT images showed sinking skin flap on the left side of the cranium, characterized by the depressed meningocele complex at the craniectomy site. 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.
