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. 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. Introduction Cranioplasty is a time tested surgical procedure to restore the form and function of either congenital or acquired calvarial defects. Full-text review yielded 11 articles discussing SoT and reconstructive techniques or. This syndrome comprises a wide spectrum of neurological symptoms including delay in neurological progression, motor symptoms, cognitive decline, impaired vigilance, and headaches [ 26 ]. Background: Sinking skin flap syndrome or paradoxical brain herniation is an uncommon neurosurgical complication, which usually occurs in the chronic phase after decompressive craniectomy. 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). (15%) had radiological SSF syndrome but no clinical symptoms except partial seizures in one. Although her general condition stabilized within 7 months after the injury, the skin of the bilateral temporal regions was markedly depressed due to large bone defects. Presentation of case: We report a case of 21 years old man with trefinated. Syndrome of the trephined, “sinking skin flap syndrome,” or “paradoxical herniation” 1, 2 is a condition unique to neurosurgical patients who have undergone craniectomy. Hakmi H, Joseph D K, Sohail A, Tessler L, Baltazar G, Stright A. Keywords:: decompressive craniectomy;Sinking skin flap syndrome is rare phenomenon that occurs in patients with large craniectomies. The characteristic phenomenon would be described as “the syndrome of the sinking skin flap, ” considering that neurological deterioration may be due solely to effect of concave deformity of the skin flap upon the underlying brain tissue. ST is also known as "sinking skin flap syndrome" and typically occurs in the weeks to months following operation. Sinking skin flap syndrome or “syndrome of the trephined” is a rare complication after a large craniectomy, with a sunken skin above the bone defect with neurological symptoms such as severe headache, mental changes, focal deficits, or seizures. This can present with either nonspecific symptoms. Abstract. 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). Syndrome of the trephined (ST) refers to the rare, reversible event of neurological deterioration following craniectomy. What is a sunken brain? Abstract. 3 ± 34. Case presentation • Young male patient , 32 years old • He had Right MCA territory infract 3. 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. 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. Search terms “syndrome of the trephined” and “sunken flap syndrome” were applied to PubMed to identify primary studies through October 2021. Urgent head CT scan was performed which, however, did not reveal new pathology, but only demonstrated findings of early stage sinking skin flap syndrome (Fig. 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. 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 ]. A 61-year-old male was. Cranioplasty using an original bone flap,. Als Sinking-Skin-Flap-Syndrom (Syndrom des sinkenden Hautlappens, SSFS) wird die Symptomkombination aus Einsinken des Hautlappens und des darunter liegenden Hirnparenchyms im Bereich einer großen Kraniektomie und einer sekundären neurologischen Verschlechterung, unabhängig von der primären Erkrankung, bezeichnet. We present a 33-year-old man who experienced hemiparesis in the upright position after craniectomy. AU Sarov M, Guichard JP, Chibarro S. We present a patient with sinking skin flap syndrome that underwent such a procedure and subsequently experienced immediate postoperative ascending transtentorial herniation and intracranial hemorrhage remote from the surgical site. Atmospheric pressure and gravity overwhelm. " Non-English-language and duplicate articles were eliminated.
