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. DOI: 10. We present a 33-year-old man who experienced hemiparesis in the upright position after craniectomy. Upright computed tomography (CT) before cranioplasty showed a remarkable shift of the brain compared to supine CT. "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. 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. : Das Sinking-Skin-Flap-Syndrom (SSFS) – eine klinisch relevante Komplikation nach dekompressiver Kraniektomie Sinking Skin Flap Syndrome (SSFS) – A Clinically Important Complication after Decompressive CraniectomyHowever, craniotomy in the postacute stage may lead to the symptoms described in our patient, the “syndrome of the sunken skin flap” , the physiopathology of which is still under investigation [5, 6], which may be precipitated by intracranial hypotension after lumbar puncture . On the basis of these data, we propose a classificationSinking skin flap syndrome, also known as syndrome of the trephined, occurs in decompressive craniectomy patients. Sinking skin flap syndrome, paradoxical herniation (more on these below). This can present with either nonspecific symptoms. Sinking skin flap syndrome (SSFS) is a condition unique to patients who have undergone craniectomy [2]. 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. This condition involves sinking of the scalp on the decompressed side deep beyond the edges of the bone defect. . Follow-up. However, SSFS is reversible after cranioplasty [3], but infectious complications must be avoided after the procedure [4]. Accordingly, cranioplasty can be undertaken as soon as necessary. 2: (A – B) Coronal CT images confirmed the sinking skin flap on the left side of the cranium and showed concave deformity of the underlying brain. 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. Introduction. Therefore, it is important to. It results from an intracerebral hypotension and requires the replacement of the cranial flap. This results in displacement of the brain across various intracranial boundaries. This avalanche of pathologic events may lead to neurologic worsening associated with a marked skin depression on the side of DC, which was introduced in 1977 as the “sinking skin flap syndrome” (SSFS). reported on cases of trephine syndrome, as characterized by severe headaches, dizziness, pain, adverse effects of cranial defects, and depressive symptoms that improved after cranioplasty. Syndrome of the trephined (sinking skin flap syndrome) with and without paradoxical herniation: a series of case reports and review. Therefore, in a patient with decompressive craniectomy, lumbar drainage or shunt surgery carries a risk to cause sinking skin flap syndrome (SSFS) or trephined syndrome, progressing to paradoxical. Clinical and radiological features (DC diameter, shape of craniectomy.

Sinking skin flap syndrome (SSFS) is a complication among long-term survivors of stroke or traumatic brain injury treated by decompressive craniectomy. The syndrome of the sinking skin flap was introduced to explain neurological deterioration after decompressive craniectomy3. Although this association led to the development of new terminology for the syndrome (“sinking skin flap syndrome”), numerous findings in the literature indicate the existence of SoT in patients without sinking skin flap morphology[. It results from the pressure difference between the atmospheric pressure and the intracranial pressure causing the brain to shift inward at the craniectomy site. 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. This phenomenon may result from CSF hypovolemia, atmospheric pressure gradient that may be aggravated by CSF diversion, dehydration, and position change1,4. We present a. Abstract.

Syndrome of the trephined also called “sinking skin flap syndrome” is a rare and late complication of the craniectomy. 2015. Sinking skin flap syndrome is a rare syndrome leading to increased intracranial pressure, known to neurosurgeons, yet uncommon and hardly ever reported in trauma patients. “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. 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. An absent cranium allows for external compression via atmospheric pressure, causing alterations in cerebral blood flow, cerebral spinal fluid. Alteration in normal anatomy and pathophysiology can result in wide variety of symptoms including altered mental status, hemodynamic instability, and dysautonomias. Cranioplasty is an in evitable operation conducted after decompressive craniectomy (DC). Postoperatively, the patient was treated with hydration and bed rest for 3 days. A 61-year-old male was hospitalized with high fever and operative site swelling. 8 3 Rotation Flap Skin Flaps Essential Surgical Skills White…Sinking skin flap syndrome is rare phenomenon that occurs in patients with large craniectomies. Management is largely conservative. Sinking skin flap syndrome is a rare syndrome leading to increased intracranial pressure, known to neurosurgeons, yet uncommon and hardly ever reported in trauma patients. Thieme E-Books & E-Journals. Hence, an early cranioplasty can serve as a. 4 cm and usually. It results from an intracerebral hypotension and requires the replacement of the cranial flap. This sinking skin flap syndrome may develop when the fascia and flap directly come into contact with the cranial parenchyma. 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. After removing the lumbar drainage, cerebrospinal fluid leakage occurred. The sinking skin flap syndrome (SSFS) or syndrome of the trephined is a rare complication that occurs in approximately 10% of large craniectomies and tends to develop several weeks to several months after surgery.

It results from the pressure difference between the atmospheric pressure and the intracranial pressure causing the brain to shift inward at the craniectomy site. The aim of the procedure was to improve cosmesis and protect the brain and avoid sinking skin flap syndrome which is a rare complication of decompressive craniectomy characterized by a sunken skin flap, neurological deterioration, and paradoxical herniation of the brain. 3. The problem was considered to have been asymptomatic sinking skin flap syndrome (SSFS). The syndrome of the sinking skin flap was introduced to explain neurological deterioration after decompressive craniectomy3. Sinking skin flap syndrome (SSFS) is a rare neurological complication in patients with traumatic haemorrhage, stroke or cerebral oedema who undergo decompressive craniectomy to relieve increased intracranial pressure. ・Sinking Skin Flap Syndrome（SSFS）. 1 It consists of a sunken skin above the bone. It is defined as a neurological deterioration accompanied by a flat or concave. In 1939, Grant et al.
