In addition to the cosmetic and protective roles, cranioplasty also has a definite therapeutic role by reversing the sensorimotor deficits and neurological deterioration that often accompanies large cranial defects, a condition commonly referred to as the ‘Motor Trephine Syndrome’ (MTS) or ‘Sinking Skin Flap syndrome’(SSFS) . It consists of a sunken scalp above the bone defect with neurological symptoms. Sinking skin flap syndrome is typically a late post-craniectomy complication, most often occurring between 1 month and 1 year after surgery. Introduction: The sinking skin flap syndrome is a complication of decompressive craniectomies. ST is also known as "sinking skin flap syndrome" and typically occurs in the weeks to months following operation. This phenomenon known as sinking skin flap syndrome or syndrome of trephined is a retroactive diagnosis rendered when a patient has reversal of postcraniectomy symptoms (described below) following cranioplasty. At the other polar extreme, external brain tamponade occurs when subgaleal fluid accumulates under pressure and 'pushes' on the brain across the craniectomy defect. With increasing numbers. This condition involves sinking of the scalp on the decompressed side deep beyond the edges of the bone defect.
