Sinking skin flap syndrome (SSFS) is a condition unique to patients who have undergone craniectomy [2]. An absent cranium allows for external compression. The syndrome of the sunken skin flap: a neglected potentially reversible phenomenon affecting recovery after decompressive craniotomy. This may result in subfalcine and/or transtentorial herniation. TLDR. It still remains a poorly understood and underestimated entity. The sinking skin flap syndrome (SSFS) is a rare complication that occurs in patients with large cranial defects following a decompressive craniectomy (DC). If the defect is closed by a prosthetic covering then it is known as a cranioplasty. Complications following craniotomy are not uncommon and Sinking Skin Flap Syndrome (SSFS) constitutes a rare entity that may present after a large Decompressive Hemicraniectomy (DC) [ 1 ]. Sinking Skin Flap Syndrome: Cause of Secondary Neurological Deterioration (PDF) Sinking Skin Flap Syndrome: Cause of Secondary Neurological Deterioration | RABII MOHAMED - Academia. A late complication following craniectomy is the “sinking” of the skin flap over the surgical site, known as the “Sunken brain and Scalp Flap Syndrome”(SSFS) or “Motor Trephine Syndrome” (MTS) (Figure (Figure2A). The spectrum of symptoms resulting from this syndrome can range from seizures, headache, neurospsychiatric disturbance, focal weakness, midbrain syndromes, and Parkinsonian symptoms. Sinking Skin Flap Syndrome, a Rare Complication of Craniectomy J Belg Soc Radiol. In patient with sinking. Syndrome of the trephined, “sinking skin flap syndrome,” or “paradoxical herniation” 1, 2 is a condition unique to neurosurgical patients who have undergone craniectomy. 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. Alteration in normal anatomy and pathophysiology can result in wide variety of symptoms including altered mental status, hemodynamic instability, and dysautonomias.

Among many, sinking flap syndrome or syndrome of the trephined or paradoxical herniation of brain is frequently underestimated. Ann. Hereby, we report for the first time that DC patients with LD can progress to SSFS or PH. (e) Intraoperative positioning of a contralateral external ventricular shunt was needed to reduce flap tension allowing uncomplicated re-suturing. An absent cranium allows for external compression via atmospheric pressure, causing alterations in cerebral blood flow, cerebral spinal fluid flow, and glucose. • Patients with this syndrome benefit having the bone flap replaced sooner rather than later. However, SSFS is reversible after cranioplasty [3], but infectious complications must be avoided after the procedure [4]. Full-text search Full-text search; Author Search; Title Search; DOI SearchThe sinking skin flap syndrome represents a less-frequent complication in patients after a decompressive craniectomy. Besides, the traditional managements reducing the intracranial pressure for herniation may exacerbate paradoxical herniation, therefore, timely diagnosis and correct treatments are significantly important. It occurs from several weeks to months after decompressive craniectomy (DC). Even less common is the development of SSFS following bone resorption after cranioplasty with exacerbation by a ventriculoperitoneal (VP) shunt. Disabling neurologic deficits, as well as the impairment of. 4). 1 It consists of a sunken skin above the bone defect with neurological symptoms such as severe headaches, mental changes, focal deficits, or seizures. At the other polar extreme, external brain tamponade occurs when subgaleal fluid accumulates under pressure and 'pushes' on the brain across the craniectomy defect. Grantham coined the term “the post traumatic syndrome” to describe similar subjective symptoms to that of “syndrome of the trephined. Five studies of TBI patients referred to the “syndrome of the trephined” or “sinking skin flap syndrome. This syndrome is associated with.

Atmospheric pressure, as well as a lack of support by the skull, causes brain tissue underneath the skin flap to sink downwards. It was first described by Grant and Norcross in 1939 as a constellation of symptoms including dizziness, undue fatigability, discomfort at the defect. This phenomenon may result from CSF hypovolemia, atmospheric pressure gradient that may be aggravated by CSF diversion, dehydration, and position change 4, 7). Commonly, it is associated with sinking of the skin near the bone-free area. In most patients, preoperative intracranial hypotension and a considerable degree of sinking of skin flap were identified; this was the only constant finding observed in these cases. “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.
