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...

COMPARATIVE STUDY
José Fidel Baizabal-Carvallo, Joseph Jankovic
Hemifacial spasm (HFS) is one of the most common presentations in patients with cranial psychogenic (functional) movement disorders (PMD). Medical records and videos of patients with PMD and HFS were reviewed to identify those with psychogenic HFS and to compare the phenomenology of psychogenic HFS with organic HFS. We identified 18 (9.8%) patients with psychogenic HFS from a cohort of 184 patients with PMDs. There were 14 (78%) women and 4 men, with a mean age at onset of 33 ± 13.5 years. These were compared with 37 consecutive patients with organic (primary) HFS...

Weimin Shen, Jie Cui, Jianbing Chen, Yi Ji, Liangliang Kong
PURPOSE: To assess the utility of internal distraction osteogenesis with Piezosurgery oblique osteotomy of supraorbital margin of frontal bone for the treatment of unilateral coronal synostosis and to study the outcome and complications of this procedure. Oblique osteotomy allows for entry into the cranial cavity, and along with parallel cut to the roof of the orbit, avoids the need to cut into the orbit which forms the frontal flap. METHODS: Oblique osteotomy was performed along the supraorbital rim to do a frontal suture of the glabella (ages of patients were less than 1 year) or on the opposite side of the supraorbital rim (ages of patients were older than 1 year) after performing a suturectomy of the effected coronal suture...

Craniofacial microsomia remains the second most common craniofacial deformity after cleft lip and palate. Mandibular pathology has been classically scored from type I to type III by the modified Pruzansky-Kaban classification. The authors report a case of a 5-year-old patient with Goldenhar syndrome and bilateral type III craniofacial macrosomia. The patient had absence of bilateral glenoid fossas, condyles, coronoids, and rami as well as hypoplasia of the symphysis, parasymphysis, and mandibular body. Reconstruction was performed using 2 costochondral rib autografts to reconstruct a ramus and assist in the development of a neo-glenoid fossa at the cranial base...

OBJECTIVE: Premature craniosynostosis of the lambdoid suture is rare. The use of differential diagnosis to rule out positional occipital plagiocephaly is crucial. Nevertheless, once diagnosed, lambdoid craniosynostosis requires corrective surgery to prevent intracranial harm and aesthetic stigma by significant dyscrania. Operative correction of the lambdoid fusion is often performed by suturectomy and helmet therapy, total occipital remodeling interventions, transposition of occipital bone flaps, or occipital advancement procedures either with or without distraction osteogenesis...
