Clinical advantages of piezosurgery have been already proved. However, few investigations have focused on the dynamics of bone healing. The aim of this study was to evaluate, in adult rabbits, bone regeneration after cranial linear osteotomies with two piezoelectrical devices (Piezosurgery(®) Medical - PM and Piezosurgery(®) Plus - PP), comparing them with conventional rotary osteotomes (RO). PP was characterized by an output power three times higher than PM. Fifteen days after surgery, histomorphometric analyses showed that the osteotomy gap produced with PM and PP was about half the size of that produced by RO, and in a more advanced stage of recovery...

PURPOSE: Cerebrospinal fluid diversion via ventricular shunt is a common treatment for hydrocephalus. Change in cranial morphology associated with a sutural fusion has been termed shunt-related or induced craniosynostosis (SRC) or craniocerebral disproportion (CCD). We present a series of patients with SRC who underwent cranial vault remodeling (CVR) and our treatment algorithm. METHODS: Thirteen patients were retrospectively reviewed who had SRC and CVR; 92% of patients had a ventriculoperitoneal (VP) shunt placed for largely intraventricular hemorrhage of prematurity (69% of patients) at a mean age of 2...

Unilateral anterior plagiocephaly is most commonly the result of deformational plagiocephaly or unilateral coronal synostosis, a premature fusion of the frontoparietal suture. However, other sutures within the coronal ring have been implicated in producing anterior cranial asymmetries. These fusions can occur in isolation or in concert with adjacent sutures. The frontosphenoidal suture is one such suture within the coronal ring that has been involved both concomitantly with and independently of frontoparietal suture fusion...

PURPOSE: The aim of this study is to compare the length of synostosis and segmented intracranial volume (SIV) with age in children with non-syndromic sagittal synostosis. METHODS: Thirty-three consecutive patients (22 boys) who had been operated by cranial vault remodeling because of sagittal synostosis were compared retrospectively from 3D-CT imaging data sets obtained from volumetric CT. The mean age of the patients at preoperative CT imaging was 0.49 (range 0...

Evaluation of infants with craniosynostosis for surgical intervention, as opposed to conservative management, remains a challenge within the field of craniofacial surgery. Studies have consistently demonstrated that surgical repair of craniosynostosis is ideally performed between 3 and 12 months of age. As such, there is limited data regarding neurocognitive development in infants who initially present with uncorrected craniosynostosis after 12 months of age. Moreover, the impact of cranial vault surgery on neurocognitive development at all ages remains under investigation...

BACKGROUND: The necessity of imaging for patients with craniosynostosis is controversial. Lambdoid synostosis is known to be associated with additional anomalies, but the role of imaging in this setting has not been established. The purpose of this study was to evaluate the impact of preoperative imaging on intraoperative and postoperative management among patients undergoing operative intervention for lambdoid craniosynostosis. METHODS: A retrospective review of patients undergoing cranial vault remodeling for lambdoid craniosynostosis between January 2006 and 2014 was conducted...

Treatment of unicoronal craniosynostosis is a surgically challenging problem, due to the involvement of coronal suture and cranial base, with complex asymmetries of the calvarium and orbit. Several techniques for correction have been described, including surgical bony remodeling, early strip craniotomy with orthotic helmet remodeling and distraction. Current distraction devices provide unidirectional forces and have had very limited success. Nitinol is a shape memory alloy that can be programmed to the shape of a patient-specific anatomy by means of thermal treatment...

Minimally invasive approaches to the surgical correction of sagittal craniosynostosis are gaining favor as an alternative to open cranial vault remodeling. In this systematic review, the reviewers evaluate the variability in described surgical techniques for minimally invasive correction of sagittal craniosynostosis. Articles were selected based on predetermined inclusion and exclusion criteria from an online literature search through PubMed, EMBASE, and the Cochrane library. Extracted data included the incisions, method of dissection, osteotomies performed, and type of force therapy utilized...

Deformities of the cranium in patients with nonsyndromic single-suture synostosis occur because of growth restriction at fused sutures and growth over compensation at normal sutures. Traditional surgery includes ostectomies of the synostotic suture to release these restricted areas and osteotomies to enable immediate cranial remodeling. In the process of reshaping the cranium, traditional approaches usually involve obliteration of both the normal functioning suture and the pathologic suture. The directive growth approach (DGA) is a new, simpler, more natural way to repair deformities caused by single-suture cranial synostosis...

BACKGROUND: Squamosal craniosynostosis is seldom reported in the craniofacial literature. Given that this is an uncommon diagnosis, phenotype and management remain unclear. The authors present a case series and review the literature to define the phenotype and management of these patients. METHODS: We retrospectively reviewed 7 patients from our institution and systematically reviewed all published cases of squamosal craniosynostosis. Demographics, medical history, imaging, clinical presentation, subsequent workup, and treatment were examined and analyzed...

OBJECTIVE: Cranial vault remodeling surgery for craniosynostosis carries the potential risk of dural venous sinus injury given the extensive bony exposure. Identification of the dural venous sinuses can be challenging in patients with craniosynostosis given the lack of accurate surface-localizing landmarks. Computer-aided design and manufacturing (CAD/CAM) has allowed surgeons to pre-operatively plan these complex procedures in an effort to increase reconstructive efficiency. An added benefit of this technology is the ability to intraoperatively map the dural venous sinuses based on pre-operative imaging...

Osteopetrosis is a heterogeneous group of uncommon congenital disorders that causes bony sclerosis and remodeling. Patients who are symptomatic can show significant neurological consequences with the involvement of cranial nerves and intracranial pressure (ICP) symptoms. We report an unusual case of a 26-year-old female with an autosomal-dominant type of osteopetrosis who presented with headache and severe visual deterioration, both attributed to the increased intracranial pressure. A hemi-cranioplasty was preformed, resulting in the resolution of her ICP symptoms and stabilization of her vision...

Brain exposure to ionizing radiation can cause functional deficits in the hippocampus, including memory impairment. However, the specific molecular mechanisms underlying irradiation-induced cognitive impairments are largely unknown. Changes in DNA methyltransferases (DNMTs) and histone deacetylases (HDACs), which are involved in DNA methylation and histone remodeling, may be associated with behavioral changes in learning and memory. We assessed changes in the levels of enzymes associated with the epigenetic modification of gene expression, including DNMT1, HDAC1, HDAC2, Sirtuin 1 (SIRT1), and acetylated histone H3 (Ace-H3) in the mouse hippocampus 1 and 30days after a single exposure to cranial irradiation (0 or 10Gy)...

A rare patient of reducible eyeball luxation after cranioplasty in a child Crouzon syndrome was reported. To remedy the patient's chronic intracranial hypertension and brachycephaly, orbitofrontal advancement and cranial vault remodeling were carried out. About 25 days of postoperation, an acute eyeball luxation was observed, with the presence of a subcutaneous accumulation of liquid in the bilateral temporal regions. The dislocated eyeballs were brought back by applying gentle manual pressure. The patient received a conservative treatment without a tarsorrhaphy...

Skull morphology in tapirs is particularly interesting due to the presence of a proboscis with important trophic, sensory and behavioral functions. Several studies have dealt with tapir skull osteology but chiefly in a comparative framework between fossil and recent species of tapirs. Only one study examined an aspect of cranial ontogeny, development of the sagittal crest (Holbrook. J Zool Soc Lond 2002; 256; 215). Our goal is to describe in detail the morphological changes that occur during the postnatal ontogeny of the skull in two representative tapir species, Tapirus terrestris and Tapirus indicus, and to explore possible functional consequences of their developmental trajectories...

This study investigated predictive risk factors of condylar remodeling changes after counterclockwise maxillomandibular advancement (CCW-MMA) and disc repositioning surgery. Forty-one female patients (75 condyles) treated with CCW-MMA and disc repositioning had cone beam computed tomography (CBCT) scans taken pre-surgery, immediately after surgery, and at an average 16 months post-surgery. Pre- and post-surgical three-dimensional models were superimposed using automated voxel-based registration on the cranial base to evaluate condylar displacements after surgery...
