Clinical presentation May range from asymptomatic or mono symptomat. 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. Sakamoto S, Eguchi K, Kiura Y, Arita K, Kurisu K (2006). In the two cases presented here, however, large cranial defects after DC resulted in a sunken scalp with neurologic deterioration. 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. The average reported craniectomy is 88. In 1939, Grant et al. It consists of a sunken scalp above the bone defect with neurological symptoms. 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. The first case of sinking skin flap syndrome was reported by Yamamura et al. Sinking skin flaps, paradoxical herniation, and external brain tamponade: a review of decompressive craniectomy management. Crossref, Medline, Google ScholarObjectives Syndrome of the Trephined (SoT) or sinking skin flap syndrome is characterised by neurological deterioration occurring after a delay post-craniectomy, with or without a significant postural component, that may improve with cranioplasty. This results in displacement of the brain across various intracranial boundaries. The syndrome encompasses a wide spectrum of. The sinking flap syndrome (SFS) is one of the complications of decompressive craniectomy (DC). 1–5 This phenomenon may result from atmospheric pressure gradient that may. 2012. Hence, an early cranioplasty can serve as a. Complications following craniotomy are not uncommon and Sinking Skin Flap Syndrome (SSFS) constitutes a rare entity that may present after a large Decompressive Craniectomy. Commonly, it is associated with sinking of the skin near the bone-free area. After removing the lumbar drainage, cerebrospinal fluid leakage occurred. Case report: A 53-year-old female sustained a severe head injury. Background: The sinking skin syndrome (SSS) is a particular complication after a decompressive craniectomy (DC). Sinking skin flap syndrome (SSFS) or "syndrome of the trephined" is a rare complication that can occur after decompressive craniectomy. Although frequently presenting with aspecific symptoms, that may be underestimated, it can lead to severe and progressive neurological deterioration and, if left untreated, even to death. ・1997年Yamamuraらによって報告. The man had car accident and developed left hemispheric subdural haematoma, multiple pelvic fractures and pulmonary contusions that led to admission to the trauma. Sinking skin flap syndrome (SSFS) is an uncommon complication that can follow decompressive craniectomy. Although changes in cerebrospinal fluid (CSF) hydrodynamics, cerebral blood flow and brain metabolism have been described as partial aspects of the pathophysiology, a. AU Sarov M, Guichard JP, Chibarro S. 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. The neurosurgery service subsequently. It appears in the weeks or months (3 months in average). However, SSFS is reversible after cranioplasty [3], but infectious complications must be avoided after the procedure [4]. Although changes in cerebrospinal fluid (CSF) hydrodynamics, cerebral blood flow and brain metabolism have been described as partial aspects of the pathophysiology, a conclusive. We present a 33-year-old man who experienced hemiparesis in the upright position after craniectomy. Bensghir Mustapha. craniotomy in which the bone flap is re-attached to the surgical defect) 1. Lastly, reconstruction of the dura defect and dead space with a musculocutaneous flap creates a large donor site defect. Neurologic. • Patients with this syndrome benefit having the bone flap replaced sooner rather than later. severe headache, tinnitus, dizziness, undue fatigability or vague discomfort at the site of the bone defect, a feeling of apprehension and insecurity, mental. The sinking skin flap syndrome represents a less-frequent complication in patients after a decompressive craniectomy. It occurs from several weeks to months after decompressive craniectomy (DC). 5 The development of symptoms is often insidious, but may be acute, and may be exacerbated by dehydration and patient positioning. Atmospheric pressure and gravity overwhelm intracranial pressure, leading to the depression of the scalp flap. and PsycINFO databases used the key words "syndrome of the trephined" and "sinking skin flap. Although changes in cerebrospinal fluid (CSF) hydrodynamics, cerebral blood flow and brain metabolism have been described as partial aspects of the pathophysiology, a. It occurs when atmospheric pressure exceeds intracranial pressure at the craniectomy defect. The sinking skin flap syndrome is a rare complication after a large craniectomy. At the other polar extreme, external brain tamponade occurs when subgaleal fluid accumulates under pressure and 'pushes' on the brain across the craniectomy defect. In three cases, a pure muscle flap with any skin paddle was transferred (7%). Knowing that the mechanism of SSSF has been speculated to be the result of the. The procedure is thought to convert cranium from a closed to an open box, hence altering the basic pathophysiology. Background: Sinking skin flap syndrome or paradoxical brain herniation is an uncommon neurosurgical complication, which usually occurs in the chronic phase after decompressive craniectomy.
