Syndrome of the trephined (sinking skin flap syndrome) with and without paradoxical herniation: a series of case reports and review. Abstract. Clinicians need to be aware of sinking skin flap syndrome and to look for abnormal neurological developments in patients with craniectomy in order to avoid unnecessary testing and to prevent its occurrence. "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. The patient then underwent cranioplasty using an autologous bone graft. 7. SSFS was first reported in 1997 by Yamamura et al who calls it a series of neurologic symptoms and signs with skin depression at the site of craniectomy. This is the American ICD-10-CM version of M95. Tessler L, Baltazar G, Stright A. We present a 33-year-old man who experienced hemiparesis in the upright position after craniectomy. The subsequent neurological workup for TIA, including normal Duplex carotid vertebral ultrasound, was unremarkable. Sinking skin flap syndrome is a craniectomy complication characterized by new neurological dysfunction that typically worsens in the upright position and improves after cranioplasty. 3 ± 34. With increasing numbers. This usually. As for our patient group, we were not able to identify risk factors for neither the external brain herniation nor the sinking skin flap syndrome. (37) studied the syndrome of the sinking skin flap (SSSF), described as one of the causes of new neurological deterioration after a large craniectomy, using dynamic CT and xenon CT to evaluate cerebral blood flow (CBF) (12, 37, 45, 46). The syndrome encompasses a wide spectrum of. 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. Sinking skin flap syndrome (SSFS) or “syndrome of the trephined” is an uncommon occurrence classically associated with decompressive craniectomy prior to cranioplasty [1, 2]. Also known by other names such as syndrome of the “trephined,” it consists of sunken skin above the bone defect along with neurological. No. Fig. 1,2 The SSF may progress to “paradoxical herniation. 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. Sunken Flap Syndrome. The symptoms and signs improve after cranioplasty. 1-3,5,7 ,8, 10)Introduction: Sinking skin flap syndrome is a rare complication of craniectomy, which is performed as a treatment of severe intracranial hypertension. It consists of a sunken skin above the bone defect with neurological symptoms such as severe headache, mental changes, focal deficits, or seizures.
