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). The sinking skin flap syndrome represents a less-frequent complication in patients after a decompressive craniectomy. 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. An absent cranium allows for external compression via atmospheric pressure, causing alterations in cerebral blood flow, cerebral spinal fluid. 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 patients where the skin may not be enough to cover the CP, due to an SSFS or skin. 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). 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. Independent of the consequences of the original aetiology that necessitated the craniectomy, the bone defect alone may be the cause of the symptoms, called 'trephined syndrome' or 'sinking skin flap s 1.

Forty years later, in 1977, the sinking skin flap syndrome was defined as new-onset neurologic deficits or even coma associated with marked skin depression at the site of craniectomy, indicating urgent. Finding a concave scalp flap after decompressive craniotomy, particularly if the patient has been shunted, is not unusual. To prevent complications following decompressive craniectomy (DC), such as sinking skin flap syndrome, studies suggested early cranioplasty (CP). 2: (A – B) Coronal CT images confirmed the sinking skin flap on the left side of the cranium and showed concave deformity of the underlying brain. Joseph V; Reilly P. This avalanche of pathologic events may lead to neurologic worsening associated with a marked skin depression on the side of DC, which was introduced in 1977 as the “sinking skin flap syndrome” (SSFS). Sinking skin flap syndrome is a rare and potentially fatal complication of a decompressive craniectomy. It occurs when atmospheric pressure exceeds intracranial pressure at the craniectomy defect. 127. 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. 55 Sakamoto S, Eguchi K, Kiura Y, Arita K, Kurisu K CT perfusion imaging in the syndrome of the sinking skin flap before and after cranioplasty. 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. 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. Europe PMC is an archive of life sciences journal literature. 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. In addition he became aphasic when seated and the symptoms subsided on lying down. Urgent head CT scan was performed which, however, did not reveal new pathology, but only demonstrated findings of early stage sinking skin flap syndrome (Fig. 1–5 This phenomenon may result from atmospheric pressure gradient that may be aggravated by CSF diversion, CSF hypovolemia. Sinking skin flap syndrome (SSFS) or "syndrome of the trephined" is a rare complication that can occur after decompressive craniectomy. or. In the two cases presented here, however, large cranial defects after DC resulted in a sunken scalp with neurologic deterioration. No problems occurred during the operation, but cerebral edema and hemorrhage were recognized on immediate postoperative computed tomography. Authors present a case series of three patients with. We also evaluated the risk factors for the incidence of SSFS in DC patients with LD. . The prevalence and characteristics of SSF syndrome after hemicraniectomy for malignant infarction of the middle cerebral. The mechanism underlying syndromic onset is poorly understood. Secondary Effects of CNS Trauma. The syndrome of the “trephined” or the “sinking skin flap” (SSF) syndrome is a rare complication after a large skull bone defect. Cranioplasty is mostly required to treat the sinking skin flap syndrome to achieve further neurological improvement 1). 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. 19 Syndrome of Trephine • Sinking skin flap syndrome. There were no language restrictions. It is of relevance not only due to its frequency, it is often underdiagnosed, but also because of the possibility. “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. The often overlooked "syndrome of the trephined" (ST) as a delayed complication of DC also known as sinking skin flap sy initially described in 1939. Advanced searchAbstract. Fig. By convention, ST refers to the development of those symptoms that are reversible after cranioplasty . Although changes in cerebrospinal fluid (CSF) hydrodynamics, cerebral blood flow and brain metabolism have been described as partial aspects of the pathophysiology, a. edu no longer supports Internet Explorer.

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. However, SSFS is reversible after cranioplasty [3], but infectious complications must be avoided after the procedure [4]. (d) Flap re-suturing was then easily obtained. 7. Sinking Skin Flap Syndrome: Cause of Secondary Neurological Deterioration. 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. 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. 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. 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. CT perfusion imaging in the syndrome of the sinking skin flap before and after cranioplasty.
