BACKGROUND: Craniosynostosis is a complex disease once it involves deep anatomical perception, and a minor mistake during surgery can be fatal. The objective of this report is to present novel three-dimensional (3D)-printed polyamide craniosynostosis models that can improve the understanding and treatment complex pathologies. METHODS: The software InVesalius was used for segmentation of the anatomy image (from three patients between 6 and 9 months old). Afterward, the file was transferred to a Three-Dimensional Printing (3DP) system and, with the use of an infrared laser, slices of powder PA 2200 were consecutively added to build a polyamide model of cranial bone...

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...

BACKGROUND: Frontofacial monobloc advancement (FFMBA) creates a communication between the anterior cranial fossa and nasal cavities. To tackle this issue, trans-orbital pericranial pedicled flaps (PF) are routinely performed in our center. This study aimed to assess the post-operative ossification of the anterior skull base and PF following FFMBA, and to identify factors influencing this ossification. METHODS: Measurements of the skull base only (SB) and of the ossified PF together with the SB (SB-OPF) were performed on CT scans at the naso-frontal (NF) and the naso-ethmoïdo-frontal (NEF) junctions...

INTRODUCTION: Posterior cranial vault distraction is a treatment for intracranial hypertension in certain cases of craniosynostosis and faciocraniosynostosis. It allows the harmonization of the skull back and prevents turricephaly. This study presents the surgical technique. TECHNICAL NOTE: Posterior cranial vault distraction osteogenesis consists of a circular osteotomy of the skull back. Four distractors are placed on the cranial flap without detachment of the dura mater...

BACKGROUND: Conventional fronto-orbital advancement and distraction osteogenesis (DOG) have been used to treat craniosynostosis, both of which are considered effective. During the authors' practice, a phenomenon of frontal hyperostosis has been observed in the patients of craniosynostosis after DOG, which has yet to be reported in the literature. The purpose of this study is trying to identify the factors related to the phenomenon. MATERIALS AND METHODS: From 1997 to 2010, all patients of craniosynostosis undergoing DOG were reviewed...

We report a case of surgical management of Crouzon syndrome with multisuture craniosynostosis presenting with increased intracranial pressure (ICP) manifesting with chronic papilledema without ventriculomegaly. A 12-month-old boy had complete resolution of papilledema after posterior cranial vault distraction followed by staged fronto-orbital advancement. Expansion of the cranial vault with posterior distraction osteogenesis posed an elegant treatment, obviating ventriculoperitoneal shunt placement for cerebrospinal fluid (CSF) diversion...

The capacity for cranial remodelling is known to be better at younger ages. The timing of cranioplasty could affect the axis of the skull base. We investigated whether age at the time of distraction is related to the outcome of endocranial morphology correction. In this retrospective study, we investigated the surgical outcome of 14 patients with unilateral craniosynostotic plagiocephaly who underwent one-piece fronto-orbital advancement without bandeau by using a distraction technique between April 2005 and December 2015...

Fronto-orbital advancement using distraction techniques involves the dura left attached to the osteotomized bone segment to avoid dead space formation and dural injury, whereas it is impossible to reshape the supraorbital bar and the frontal bone complex, when necessary. Our approach combines advantageous parts of conventional and distraction osteogenesis techniques as remodel and distract the supraorbital bar and frontal bone complex as a free bone graft. Twenty-seven patients either being syndromic and nonsyndromic craniosynostosis, with at least 3 years of follow-up were reviewed in this study...

OBJECTIVE: Virtual Surgical Planning (VSP) and computer-aided design/computer-aided manufacturing (CAD/CAM) have recently helped improve efficiency and accuracy in many different craniofacial surgeries. Research has mainly focused on the use in the adult population with the exception of the use for mandibular distractions and cranial vault remodeling in the pediatric population. This study aims to elucidate the role of VSP and CAD/CAM in complex pediatric craniofacial cases by exploring its use in the correction of midface hypoplasia, orbital dystopia, mandibular reconstruction, and posterior cranial vault expansion...

The use of posterior calvarial distraction (PCD) for the management of craniosynostosis is well recognized. The advantages of using this technique include increased cranial volume, decreased intracranial pressure, relief of posterior fossa crowding, improved cerebrospinal fluid (CSF) circulation at the cranio-cervical junction with cessation, and possible resolution of syrinx.The authors retrospectively review their first 50 patients who have undergone PCD under the senior author's care in our unit.The demographics, diagnoses, intraoperative approach with techniques in distractor placement and outcomes of each patient were obtained through an electronic craniofacial database and written patient records...

CASE REPORT: A 4-month-old female intact American Pit Bull Terrier was presented for right pelvic limb lameness 1 day after the dog had been hit by an all-terrain vehicle. Orthogonal radiographs of the right stifle revealed a Salter-Harris type IV fracture through the proximal tibial physis extending caudodistally through the proximal tibial metaphysis. The distal tibia was markedly displaced cranially, laterally and proximally, resulting in complete overriding of the fracture segments...

The purposes of surgery for craniosynostosis are to release increased intracranial pressure and to normalize cranial shape. The procedure was developed from a simple strip craniectomy in practice which ranged from the removal of the fused suture before the 1960s to total calvarial remodeling after 1970s and later methods of the 1990s, such as distraction and its modifications. According to its history, craniofacial surgeons might be changing their procedures with more effective, than less invasive ways. Since the late 1990s, when the distraction was applied to the craniofacial surgery, the gradual expansion, in particular of the anterior cranium, common in Japan, has long been controversial until the Caucasians accepted its use for the posterior cranium...

BACKGROUND: Posterior cranial vault distraction (PCVD) is a technique widely used in surgical treatment of craniosynostosis when cranial expansion is required. It has proven to be safe and to allow a significant increase of intracranial volume. OBJECTIVE: To evaluate increases in intracranial volume as a result of PCVD performed in Oulu Craniofacial center using 2 different methods based on 3-dimensional (3-D) photogrammetric imaging or plain skull radiographs. METHODS: All children less than 16 yr of age who were treated by PCVD (n = 31) from 2009 to 2015 at the Oulu Craniofacial Center were included...

There are many surgical techniques for craniosynostosis. However, the indications for and timing of surgery still remain unclarified. Most of the skull growth in craniosynostosis is completed in the first year, and the bone is strong enough to undergo distraction osteogenesis. However, previous reports showed that patients operated on before 1 year of age had better IQ than those operated later in life. This report aims to consider the best timing for cranial expansion and surgical strategy for Apert syndrome...
