It results from an intracerebral hypotension and requires the replacement of the cranial flap. (d) Flap re-suturing was then easily obtained. It results from the pressure difference between the atmospheric pressure and the intracranial pressure causing the brain to shift inward at the craniectomy site. 7 Classically, SSFS tends to occur in the upright position and to resolve in the Trendelenburg position, which could help to detach. Following an inner ellipse of the previous DC-surgery scar could contribute in most cases to the preservation of the vascular perfusion even if an incision outside of the ellipse might be needed in certain settings such as sinking skin flap syndrome (SSFS). 2 cm(2) versus 88.

Sinking skin flap syndrome is a craniectomy complication characterized by new neurological dysfunction that typically worsens in the upright position and improves after cranioplasty. In some cases, patients with SSFS are unable to undergo immediate. Bone defects of the skull are observed in various pathological conditions, including head trauma and conditions. The sinking skin flap syndrome may progress to "paradoxical herniation" as a consequence of the atmospheric pressure exceeding intracranial pressure and may eventually lead to coma and death 6). Bone resorption of the bone flap was not observed in any case (Table 2). 5 The development of symptoms is often insidious, but may be acute, and may be exacerbated. Four days after his cranioplasty, follow-up CT images showed reversal of the midline shift with no significant complications in the underlying brain . : 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 . 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 phenomenon may result from CSF hypovolemia, atmospheric pressure gradient that may be aggravated by CSF diversion, dehydration, and position change1,4. Hallmark of SSFS is the sinking of the scalp to a plane lower than the edges of the skull defect in the setting of neurological. Introduction: The sinking skin flap syndrome is a complication of decompressive craniectomies. Cranioplasty is mostly required to treat the sinking skin flap syndrome to achieve further neurological improvement 1). Aphasia precipitated by adoption of erect posture was the uncommon and easily identifiable neurological finding in this patient that drew our attention to the fact that he might be having the “sinking scalp flap syndrome.
