Decompressive craniectomy (DC) is commonly performed in patients with intracranial hypertension or brain edema due to traumatic brain injury. 8) In 1977, Yamaura et al. Upright computed tomography (CT) before cranioplasty showed a remarkable shift of the brain compared to supine CT. 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. This sinking skin flap syndrome may develop when the fascia and flap directly come into contact with the cranial parenchyma. 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]. ; Roehrer, S.

Als Sinking-Skin-Flap-Syndrom (Syndrom des sinkenden Hautlappens, SSFS) wird die Symptomkombination aus Einsinken des Hautlappens und des darunter liegenden Hirnparenchyms im Bereich einer großen Kraniektomie und einer sekundären neurologischen Verschlechterung, unabhängig von der primären Erkrankung, bezeichnet. Joseph V; Reilly P. ” Syndrome of the trephined had an overall frequency of 10 % (43/425) following DC [25, 27, 38, 101, 103]. Atmospheric pressure and gravity overwhelm intracranial pressure, leading to the depression of the scalp flap. It results from an intracerebral hypotension and requires the replacement of the cranial flap. 2012 Oct;8(2):149-152. One hypothesis has been that atrophy of the infarcted tissue leads to a decrease in the intracranial volume and subsequently a decrease in intracranial. Getting an X-ray done in lying down and standing position is a simple tool by which this diagnosis can be confirmed. The syndrome of the trephined was introduced in 1939 as a feeling of tenderness, discomfort, and insecurity located at the site of craniectomy.

To prevent complications following decompressive craniectomy (DC), such as sinking skin flap syndrome, studies suggested early cranioplasty (CP). Therefore, the scalp contraction may not. Finding a concave scalp flap after decompressive craniotomy, particularly if the patient has been shunted, is not unusual. An absent cranium allows for external compression via atmospheric pressure, causing alterations in cerebral blood flow, cerebral spinal fluid flow, and glucose. 2 became effective on October 1, 2023.

CT perfusion imaging in the syndrome of the sinking skin flap before and after cranioplasty. After surgical decompression, the scalp may sink due to the lack of underlying bone to support the. The procedure is thought to convert cranium from a closed to an open box, hence altering the basic pathophysiology. Authors present a case series of three patients with. [] Although it is very rare, sinking skin flap syndrome may lead to paradoxical brain herniation, which is. Europe PMC is an archive of life sciences journal literature. Background: Sinking Skin Flap Syndrome (SSFS) is a postoperative phenomenon that occurs in decompressive hemicraniectomy patients after sustaining brain injury. Although frequently presenting with aspecific symptoms, that may be. The sinking skin flap syndrome represents a less-frequent complication in patients after a decompressive craniectomy. Hereby, we report for the first time that DC patients with LD can progress to SSFS or PH. Zusammenfassung. In the two cases presented here, however, large cranial defects after DC resulted in a sunken scalp with neurologic deterioration. A 77-year-old male patient with an acute subdural hematoma was treated using a. sinking skin flap. Cranioplasty is an in evitable operation conducted after decompressive craniectomy (DC). 4). No problems occurred during the operation, but cerebral edema and hemorrhage were recognized on immediate postoperative computed tomography. reported on cases of trephine syndrome, as characterized by severe headaches, dizziness, pain, adverse effects of cranial defects, and depressive symptoms that improved after cranioplasty. As the herniated brain tissue recedes, the skin flap from the surgical site can become sunken. 1–5 This phenomenon may result from atmospheric pressure gradient that may be aggravated by CSF diversion, CSF hypovolemia. However, several groups reported higher complication rates in early CP. Although changes in cerebrospinal fluid (CSF) hydrodynamics, cerebral blood flow and brain metabolism have been described as partial aspects of the pathophysiology, a conclusive. 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. Perfusion magnetic resonance imaging showed subclinical sinking skin flap syndrome, and he underwent cranioplasty on postoperative day 58. Sinking skin flap syndrome (SSFS) or “syndrome of the trephined” is a rare complication that can occur after decompressive craniectomy. 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.

Although changes in cerebrospinal fluid (CSF) hydrodynamics, cerebral blood flow and brain metabolism have. Zusammenfassung. “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. 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. The sinking skin syndrome (SSS) or syndrome of the trephined, as first described by Grant and Norcross,[] is a very particular complication after a decompressive craniectomy (DC). In the two cases presented here, however, large cranial defects after DC resulted in a sunken scalp with neurologic deterioration. Hence, an early cranioplasty can serve as a. Sinking skin flap syndrome is a rare syndrome leading to increased intracranial pressure, known to neurosurgeons, yet uncommon and hardly ever reported. Remember me on this computer. We also evaluated the risk factors for the incidence of SSFS in DC patients with LD. Most reports of SSFS were accompanied by CSF hypovolemic condition,. Thus, there is growing evidence that the incidence of SoT might be underestimated because of a lack of. Sinking skin flap syndrome is defined by a series of neurological symptoms with skin depression at the site of cranial defect. The neuro-intensive care team should be prepared to diagnose. Trephine syndrome, also known as the sinking skin flap syndrome, is a relatively late complication in post-craniectomy patients. In most patients, preoperative intracranial hypotension and a considerable degree of sinking of skin flap were identified; this was the only constant finding observed in these cases. 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. ST is also known as “sinking skin flap syndrome” and typically occurs in the weeks to months following operation. Sinking skin flap syndrome (SSFS) is a condition unique to patients who have undergone craniectomy [2]. Brainstem hemorrhages classify as primary or secondary. ・SSFSとは？. An absent cranium allows for external compression via atmospheric pressure, causing alterations in cerebral blood flow, cerebral spinal fluid.
