Clinical presentation May range from asymptomatic or mono symptomat. This phenomenon may result from CSF hypovolemia, atmospheric pressure gradient that may be aggravated by CSF diversion, dehydration, and position change1,4. Remarkably, the brain parenchyma was more often still above. It results from the pressure difference between the atmospheric pressure and the intracranial pressure causing the brain to shift inward at the craniectomy site. 8 3 Rotation Flap Skin Flaps Essential Surgical Skills White…Sinking skin flap syndrome is rare phenomenon that occurs in patients with large craniectomies.

Alteration in normal anatomy and pathophysiology can result. Cranioplasty is an in evitable operation conducted after decompressive craniectomy (DC). Lumbar drainage was performed; however, sinking skin flap syndrome was observed. 1 It consists of a sunken skin above the bone defect with neurological symptoms such as severe headaches, mental changes, focal deficits, or seizures. Neurol Med Chir 17: 43-53. 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. 0%, p < 0. 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. Atmospheric pressure and gravity overwhelm. Sinking skin flap syndrome: a case of improved cerebral blood flow after cranioplasty. BACKGROUND Sinking skin flap syndrome (SSFS) is an uncommon complication that can follow decompressive craniectomy. The mechanism underlying syndromic onset is poorly understood. The search yielded 19 articles with a total of 26 patients. 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). 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. ・広範な外減圧術後の稀な合併症. 117 Corpus ID: 36217191; Reperfusion Injury after Autologous Cranioplasty in a Patient with Sinking Skin Flap Syndrome @article{Kwon2012ReperfusionIA, title={Reperfusion Injury after Autologous Cranioplasty in a Patient with Sinking Skin Flap Syndrome}, author={Sae Min Kwon and Jin Hwan. Although changes in cerebrospinal fluid (CSF) hydrodynamics, cerebral blood flow and brain metabolism have been described as partial aspects of the pathophysiology, a conclusive. It consists in neurological deterioration believed to be related to the barometric pressure changes over the brain after removing the skull, affecting also. " Non-English-language and duplicate articles were eliminated. 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. 19 Syndrome of Trephine • Sinking skin flap syndrome. Introduction. The neuro-intensive care team should be prepared to diagnose and treat a spectrum of decompressive craniectomy complications including: cerebral contusions, infections, seizures, intra- and extra-axial hemorrhages and fluid collections, sinking skin flap syndrome or syndrome of the trephined, paradoxical herniation, and external brain. Ann. The sinking skin flap syndrome represents a less-frequent complication in patients after a decompressive craniectomy.
