Sinking skin flap syndrome in the multi-trauma patient: a paradoxical management to TBI post craniectomy. The neurological status. ” Syndrome of the trephined had an overall frequency of 10 % (43/425) following DC [25, 27, 38, 101, 103]. This usually. 198. If you would like to make an appointment with an expert in the Reconstructive Craniofacial. Syndrome of the trephined, or sinking skin flap syndrome, is a rare complication following craniectomy, showing a variety of neurological symptoms that improve after cranioplasty. Cranioplasty is an in evitable operation conducted after decompressive craniectomy (DC). Introduction Cranioplasty is a time tested surgical procedure to restore the form and function of either congenital or acquired calvarial defects. (37) studied the syndrome of the sinking skin flap (SSSF), described as one of the causes of new neurological deterioration after a large craniectomy, using dynamic CT and xenon CT to evaluate cerebral blood flow (CBF) (12, 37, 45, 46). 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). ST is also known as “sinking skin flap syndrome” and typically occurs in the weeks to months following operation. Clinical presentation May range from asymptomatic or mono symptomat. Background: Sinking skin flap syndrome or paradoxical brain herniation is an uncommon neurosurgical complication, which usually occurs in the chronic phase after decompressive craniectomy. The problem was considered to have been asymptomatic sinking skin flap syndrome (SSFS). In patients where the skin may not be enough to cover the CP, due to an SSFS or skin. 2020; 2020 (06):a172. 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. The term sinking skin flap syndrome assumes that the herniation in this setting results from the combined effects of brain gravity and CSF depletion in patients who have undergone decompressive craniectomy [10, 11]. 1 It consists of a sunken skin above the bone defect with neurological symptoms such as severe headaches, mental changes, focal deficits, or seizures. 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. ・広範な外減圧術後の稀な合併症. 8) In 1977, Yamaura et al. Hereby, we report for the first time that DC patients with LD can progress to SSFS or PH. Atmospheric pressure, as well as a lack of support by the skull, causes brain tissue underneath the skin flap to sink downwards. 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. Postoperatively, strict follow-up and early cranioplasty are warranted . His condition was complicated with ventilator associated pneumonia, and was treated with IV Fortum and Cefepime. Sinking skin flap syndrome (SSFS) or “syndrome of the trephined” is an uncommon occurrence classically associated with decompressive craniectomy prior to cranioplasty [1, 2]. 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. 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). 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. 1. Europe PMC is an archive of life sciences journal literature. It results from an intracerebral hypotension and requires the replacement of the cranial flap. Most reports of SSFS were accompanied by CSF hypovolemic condition,. Disabling neurologic deficits, as well as the impairment of. . g. However, it may result in sinking skin flap syndrome (SSFS) in some patients, for which cranioplasty is the only treatment option. TLDR. Abstract. It consists of a sunken skin above the bone defect with neurological symptoms such as severe headache, mental changes, focal deficits, or seizures. 5 The development of symptoms is often insidious, but may be acute, and may be exacerbated by dehydration and patient positioning. Even less common is the development of SSFS following bone resorption after cranioplasty with exacerbation by a ventriculoperitoneal (VP) shunt. Full-text search Full-text search; Author Search; Title Search; DOI SearchThe 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. The impression was of sinking skin flap syndrome, so cranioplasty with bone cement was performed. The mechanism underlying syndromic onset is not entirely. Upright computed tomography (CT) before cranioplasty showed a remarkable shift of the brain compared to supine CT. 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.

Sinking skin flap syndrome (SSFS) or “syndrome of the trephined” is a rare complication that can occur after decompressive craniectomy. The syndrome of the sinking skin flap was introduced to explain neurological deterioration after decompressive craniectomy3. 51. "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. This sinking skin flap syndrome may develop when the fascia and flap directly come into contact with the cranial parenchyma. 2017. Results. 3. (15%) had radiological SSF syndrome but no clinical symptoms except partial seizures in one. Follow-up. An absent cranium allows for external compression via atmospheric pressure, causing alterations in cerebral blood flow, cerebral spinal fluid. 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.

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. His condition was generally improved. The problem was considered to have been asymptomatic sinking skin flap syndrome (SSFS). Sinking skin flap syndrome is a craniectomy complication characterized by new neurological dysfunction that typically worsens in the upright position and improves after cranioplasty. (38%). He was diagnosed with sinking skin flap syndrome consistent with altered mental status and a sunken skin flap with increased midline shift. 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 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. y community. It occurs from several weeks to months after decompressive craniectomy (DC). Sinking skin flap syndrome (SSFS) is a rare complication of decompressive craniectomy (DC) and causes a wide range of neurological deficits. Clin Neurol Neurosurg 2006;108(6):583–585. In patient with sinking skin flap syndrome, cerebral blood flow and cerebral metabolism are decreased by.
