Alteration in normal anatomy and pathophysiology can result. PMID: 26906112. The pathophysiology of this phenomenon is not completely clear, but is felt to be related to the conversion of a closed system to an open. We report such a rare case in 38-year-old man who underwent right-sided. The defect is usually covered over with a skin flap. 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. This syndrome comprises a wide spectrum of neurological symptoms including delay in neurological progression, motor symptoms, cognitive decline, impaired vigilance, and headaches [ 26 ]. Decompressive craniotomy. An absent cranium allows for external compression. AU Sarov M, Guichard JP, Chibarro S. Sakamoto S, Eguchi K, Kiura Y, Arita K, Kurisu K (2006). Both autologous bone flaps and alloplastic substitutes have been surgically explored over time to achieve the pre-morbid contour and eliminate the existing and anticipated complications like the “Sinking flap Syndrome”. INTRODUCTION. Edema continued to progress, but edema and. Patients with the classical “Motor trephine syndrome/ Sinking skin flap syndrome” following large craniectomy defects, may hugely benefit from an early cranioplasty procedure, with a reversal of features of this syndrome and early recovery of their neurological and cognitive functions.
