TLDR
CT perfusion imaging after cranioplasty revealed the improvement of cerebral blood flow not only on the symptomatic side but also on the contralateral side, in the first reported case of SSSF examined with CT perfusion Imaging before and after crANIoplasty.About:

Figures
Fig. 4 (A) The enhanced CT image was one of four axial slices used to make a cerebral blood flow map from CT perfusion data. The post-operative CT showed an improvement of the brain compression and no new lesion. 
Fig. 2 (A) The enhanced CT image was one of four axial slices used to make a cerebral blood flow map from CT perfusion data. The pre-operative CT showed cerebral infarction in the right hemisphere and bone defect by fronto-temporo-parietal craniectomy. (B) The CBF values of the right and left hemispheres on the CBF map were 23.1 and 37.4 cc/100g/min, respectively. 
Fig. 1 (A) The pre-operative bone image of three-dimensional CT with a lateral view showed a compressed brain and cranial bone defect by fronto-temporo-parietal craniectomy. (B) The pre-operative surface anatomy scanning image on three-dimensional CT with a superior view showed a compressed brain.

Complications of cranioplasty following decompressive craniectomy: analysis of 62 cases.
TL;DR: Decompressive craniectomy is a potentially life-saving procedure used in the treatment of medically refractory intracranial hypertension, most commonly in the setting of trauma or cerebral infarction, but patients undergoing a bifrontal crANIectomy are at significantly increased risk for postcranioplasty complications, including the need for reoperation.

TL;DR: It is hypothesized that Syndrome of the trephined is often underdiagnosed and recommend a multifaceted approach for consistent evaluation, due to current weaknesses in objectivity.

Cranioplasty of large cranial defect at an early stage after decompressive craniectomy performed for severe head trauma.
TL;DR: It is considered that with the appropriate choice of patients and materials, early cranioplasty for large cranial defects after decompressive craniectomy would be safe and helpful for the improvement of patients' neurologic function and prognosis.

Cranioplasty using polymethyl methacrylate prostheses.
TL;DR: A CAD/CAM PMMA prosthesis is an excellent alternative when no autogenous bone graft harvested during craniectomy is available and was comparable to that for autograft bone flaps.

TL;DR: The neuro-intensive care team should be prepared to diagnose and treat a spectrum of decompressive craniectomy complications including: cerebral contusions, infections, seizures, intra- and extra-axial hemorrhages and fluid collections, sinking skin flap syndrome or syndrome of the trephined, paradoxical herniation, and external brain tamponade.

TL;DR: 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.

Post-cranioplasty cerebrospinal fluid hydrodynamic changes: Magnetic resonance imaging quantitative analysis
TL;DR: Using dynamic phase-contrast magnetic resonance imaging, arterial, venous, and cerebrospinal fluid flow into and out of the skull is measured before and after cranioplasty in one patient whose bone flap was removed because of osteomyelitis and significant changes in the oscillatory CSF flow are reported.
