It is defined as a neurological deterioration accompanied by a flat or concave. The “syndrome of the trephined” or “sinking skin flap syndrome” is a rare complication of a craniectomy characterized by postoperative neurological deterioration caused by cortical dysfunction of the area below the craniotomy that improves after cranioplasty. Sinking skin flap syndrome is a rare complication of decompressive craniectomy characterized by a sunken skin flap, neurological deterioration, and paradoxical herniation of the brain. After bone removal, the stretched scalp above the bone defect may sink due to the absence of underlying bone to support the atmospheric pressure. Imaging Findings. 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 (SSFS) is a rare complication of decompressive craniectomy (DC) and causes a wide range of neurological deficits. Paradoxical brain herniation, also known as sinking skin flap syndrome or syndrome of the trephined, is a rare and potentially fatal complication of decompressive craniectomy. Sinking skin flap syndrome (SSFS) or “syndrome of the trephined” is a rare complication that can occur after decompressive craniectomy. It occurs from several weeks to months after decompressive craniectomy (DC). Sinking skin flap syndrome (SSFS) or paradoxical herniation (PH) is a rare complication and sporadically occurs in patients after DC. This results in displacement of the brain across various intracranial boundaries. A 77-year-old male patient with an acute subdural hematoma was treated using a. After surgical decompression, the scalp may sink due to the lack of underlying bone to support the. g. A diagnosis of syndrome of the trephined or “sinking skin flap syndrome were considered in them, and all of them improved after cranioplasty. "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. 8 3 Rotation Flap Skin Flaps Essential Surgical Skills White…Sinking skin flap syndrome is rare phenomenon that occurs in patients with large craniectomies. Objective To prevent complications following decompressive craniectomy (DC), such as sinking skin flap syndrome, studies suggested early cranioplasty (CP). We present a 33-year-old man who experienced hemiparesis in the upright position after craniectomy. An absent cranium allows for external compression via atmospheric pressure, causing alterations in cerebral blood flow, cerebral spinal fluid. Presentation of case: We report a case of 21 years old man with trefinated. in the following article: Paradoxical brain herniation - “ Paradoxical brain herniation, also known as sinking skin flap syndrome or syndrome of the trephined, is a rare and potentially fatal complication. 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. It occurs from several weeks to months after decompressive craniectomy (DC). Disabling neurologic deficits, as well as the impairment of. Therefore, it is important to. 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). 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. Europe PMC is an archive of life sciences journal literature. 2 may differ. Abstract. Complications following craniotomy are not uncommon and Sinking Skin Flap Syndrome (SSFS) constitutes a rare entity that may present after a large. Conclusion: Causes of cerebral edema and hemorrhage immediately after cranioplasty include reperfusion, reduction of automatic adjustment function, sinking skin flap syndrome, negative pressure due to s. ・1997年Yamamuraらによって報告.
