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. However, it may result in sinking skin flap syndrome (SSFS) in some patients, for which cranioplasty is the only treatment option. CT perfusion imaging in the syndrome of the sinking skin flap before and after cranioplasty [Case Reports]. Atmospheric pressure and gravity overwhelm intracranial pressure, leading to the depression of the scalp flap. 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. 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. Management is largely conservative. [Europe PMC free article] [Google Scholar] 4. Bensghir Mustapha. It consists of a sunken skin above the bone defect with neurological symptoms such as severe headache, mental changes, focal deficits, or seizures. Sinking Skin Flap Syndrome . 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. 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]. 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 brain tissue. In patient with sinking. Sunken Flap Syndrome. If the defect is closed by a prosthetic covering then it is known as a cranioplasty. The mechanism underlying syndromic onset is poorly understood. sinking skin flap syndrome (aka, syndrome of the trephined) Basics: This usually occurs several months postoperatively. Alteration in normal anatomy and pathophysiology can result in wide variety of symptoms including altered mental status, hemodynamic instability, and dysautonomias. Europe PMC is an archive of life sciences journal literature. 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]. This syndrome is associated with sensorimotor deficit. " Non-English-language and duplicate articles were eliminated. Syndrome of the trephined, “sinking skin flap syndrome,” or “paradoxical herniation” 1, 2 is a condition unique to neurosurgical patients who have undergone craniectomy.
