Surgical Management of Hypertelorism: The 3D Animated Technical Note.

The hypertelorism surgery is a complex procedure requiring a long learning curve. Even though the box osteotomy technique is well described in literature, its representation is generally based on texts and illustrations that do not really give a 3-dimensional or a dynamic point of views. The authors present a 3-dimensional animated video, Supplemental Digital Content 1, http://links.

Computer-Assisted Frontofacial Monobloc Advancement and Facial Bipartition for Pfeiffer Syndrome: Surgical Technique.

Background: In patients with Pfeiffer syndrome, several corrections are required to correct facial retrusion, maxillary deficiency, or even hypertelorism. The frontofacial monobloc advancement (FFMA) and the facial bipartition (FB) are the gold standard surgeries. We present the correction of this deformity using a simultaneous computer-assisted FFMA and FB.

How Accurate Is Computer-Assisted Orbital Hypertelorism Surgery? Comparison of the Three-Dimensional Surgical Planning with the Postoperative Outcomes.

Surgery of orbital hypertelorism (ORH) remains an imprecise surgical procedure depending on the experience and habits of the craniofacial surgical teams. Computer-assisted surgery (CAS) has developed dramatically in craniofacial surgery, but there is no current study assessing its accuracy for ORH surgery. This study aimed to assess the input of CAS and especially the accuracy of the cutting guide-based procedures.

Posterior fossa tumors in children: Radiological tips & tricks in the age of genomic tumor classification and advance MR technology.

Imaging plays a major role in the comprehensive assessment of posterior fossa tumor in children (PFTC). The objective is to propose a global method relying on the combined analysis of radiological, clinical and epidemiological criteria, (taking into account the child's age and the topography of the lesion) in order to improve our histological approach in imaging, helping the management and approach for surgeons in providing information to the patients' parents. Infratentorial tumors are the most frequent in children, representing mainly medulloblastoma, pilocytic astrocytoma and brainstem glioma.

Is It Safe To Use Frontofacial Monobloc Advancement and Cutting Guides on Adult Patients with Crouzon Syndrome? Introducing 2 Cases on 41- and 56-Year-Old Patients.

Background: Patients with Crouzon syndrome are mainly treated in childhood by frontofacial monobloc advancement to avoid ophthalmic, neurologic, and maxillary complications. There is no reported case of surgery on adult patients with Crouzon syndrome in the literature. However, when faced with 2 cases of adult patients showing severe quality of life deterioration, our team decided to make an attempt using monobloc advancement technique.

Use of cutting guides during craniosynostosis sequelae surgery: A comparative study between computer-assisted planning and post-operative results.

Background: The authors compared results of craniofacial reconstruction surgery using cutting guides with planned reconstruction on patients presenting craniosynostosis surgery sequelae.

Methods: This is a retrospective study performed on seven patients who had undergone craniofacial reconstructive surgery in University Hospital Center of Tours (France) in 2015. Patients had long-term sequelae of trigonocephaly and anterior plagiocephaly surgery.

Long-Term Assessment of Suturectomy in Trigonocephaly and Anterior Plagiocephaly.

Introduction: Techniques for treating trigonocephaly and anterior plagiocephaly have evolved from the initial suturectomy technique to frontal cranioplasty. The authors evaluated the suturectomy technique in adolescent patients with these craniosynostoses, by carrying out a retrospective, long-term assessment at the end of growth.

Methods: Patients with anterior plagiocephaly or trigonocephaly were included.

Frontofacial Monobloc Advancement With Simultaneous Frontal Cranioplasty in Adolescents With Residual Apert Syndrome Deformations.

Introduction: The treatment of faciocraniosynostosis has steadily evolved since the introduction of craniofacial surgery in the 1950s. The aim of this study is to demonstrate the positive results obtained by frontofacial monobloc advancement with simultaneous frontal cranioplasty in adolescents with adult facial bones and residual Apert syndrome deformations.

Materials And Methods: Three adolescents underwent surgery between September 1, 2010 and March 31, 2011.

Prenatal findings in carpenter syndrome and a novel mutation in RAB23.

Carpenter syndrome is caused by mutations of the RAB23 gene. To date, 12 distinct mutations have been identified among 34 patients from 26 unrelated families. We report on the prenatal findings in a fetus with Carpenter syndrome with a novel RAB23 mutation.

Orbitofrontal monobloc advancement for Crouzon syndrome.

Introduction: Usually, patients suffering from Crouzon syndrome have synostosis of coronal sutures, exophthalmia, hypertelorism, and hypoplasia of the middle third of face. Sometimes maxillary retrusion is absent, so these patients have class I or II relationship. In these cases, frontofacial monobloc advancement, which is the gold standard, increases the maxillo-mandibular dysmorphia.

Papillary tumor of the pineal region in a child: case report and review of the literature.

Case Report: A 13-year-old boy presented with a history of intracranial hypertension. Radiologic studies revealed triventricular hydrocephalus secondary to a space-occupying lesion in the pineal region. Endoscopic third ventriculostomy was performed to treat hydrocephalus, and the lesion was biopsied.

Cbl-mediated ubiquitination of alpha5 integrin subunit mediates fibronectin-dependent osteoblast detachment and apoptosis induced by FGFR2 activation.

Fibroblast growth factor receptor signaling is an important mechanism regulating osteoblast function. To gain an insight into the regulatory role of FGF receptor-2 (FGFR2) signaling in osteoblasts, we investigated integrin-mediated attachment and cell survival in human calvarial osteoblasts expressing activated FGFR2. FGFR2 activation reduced osteoblast attachment on fibronectin.
