In craniofacial surgery, a wide spectrum of pathological conditions are usually treated. The aetiology of these could be congenital, traumatic, infective, post-tumor resection, postradiation, autoimmune, iatrogenic, or other miscellaneous conditions. The surgical approach for the procedures is usually via a coronal incision. In a large proportion of the patients, the frontal bone is removed to obtain intracranial access. The frontal bone is then replaced either in its original form or in a remodeled state. In congenital conditions the supraorbital bar and frontal bone is often also removed, remodeled, and replaced...

REVIEW
Michael Wigton, Megan Friend, Zhongyu Li
Radioulnar synostosis can cause substantial loss of function, and surgical treatment can be challenging. Recurrence of the contracture related to scar or reformation of the synostosis is problematic. Several techniques have been described for prevention of recurrence. We present a technique utilizing a free wrap around adipofascial graft for interposition and circumferential coverage of the ulna after resection of the heterotopic bone. We believe this technique has the advantages of technical simplicity, secure interposition, and reliable outcomes...

Craniosynostosis has an incidence of 1 in 2000 to 2500 live births and may be corrected through several methods including total calvarial remodeling and frontal orbital advancement remodeling. Blood loss during craniosynostosis surgery can be substantial, ranging from 20% to 500% of total circulating volume with a high associated risk of transfusion-related adverse events. The authors performed a retrospective analysis of all patients undergoing surgery for craniosynostosis at a tertiary pediatric craniofacial center with a focus on blood loss and subsequent transfusion...

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...

INTRODUCTION: Isolated frontosphenoidal synostosis (FS) is a rare cause of fronto-orbital plagiocephaly that can be challenging to distinguish from isolated unicoronal synostosis (UC). The purpose of this paper is to analyze differences in fronto-orbital dysmorphology between the 2 conditions, to describe approaches for surgical correction, and to report surgical outcomes between FS and UC patients in a casecontrol fashion. METHODS: Patients treated for craniosynostosis over a 12-year period at our institution were retrospectively evaluated under institutional review board approval...

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...

BACKGROUND: Although the charting of normal intracranial volume (ICV) is fundamental for managing craniosynostosis, Asian norms in this regard are unknown. The purpose of this study was to establish a growth curve for ICVs in a large series of normal Asian children, providing reference values to guide corrective surgery. METHODS: A total of 124 normal children (male, 63; female, 61) and 41 children diagnosed with craniosynostoses were analyzed. Patients aged 0-8 years presenting to the emergency room and subjected to computed tomography (CT) for head trauma served as the reference cohort...

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: Numerous techniques for the surgical management of lambdoidal synostosis have been previously described; however, no best practice technique currently exists. Surgical procedures range from complete posterior calvarial reconstruction to distraction osteogenesis techniques. Our primary purpose is to describe a novel approach to correct unilateral or bilateral lambdoidal synostosis. METHODS: A retrospective review was performed on a single surgeon's experience with craniosynostosis (1994-2014)...

BACKGROUND: Endoscopic approaches for craniosynostosis are a growing field in pediatric neurosurgery. In metopic synostosis, previous reports for complete fronto-orbital remodeling have proposed an intervention with multiple incisions (bregmatic, tarsal, and preauricular) to open frontonasal and frontoethmoidal synostotic sutures, and orbital roof. METHODS: We propose a technique to complete all these osteotomies with a unique incision anterior to the bregmatic fontanel under 3D endoscopic vision, and review possible complications, limits, and pitfalls...

BACKGROUND: Sacrum is a triangular bone placed in the base of the spine and formed by the synostosis of five sacral vertebrae (S1-S5). Its upper part is connected with the inferior surface of the body of L5 vertebra forming the lumbosacral joint, while its lower part is connected with the base of the coccyx forming the sacrococcygeal symphysis, an amphiarthrodial joint. The existence of four pairs of sacral foramen in both anterior and posterior surface of the sacrum is the most common anatomy...

PURPOSE: The effect of synostosis is not confined to the immediate vicinity of the suture. The authors hypothesized metopic craniosynostosis results in migration of lateral structures from midline, and differences in segmental volume of the cranial fossa. METHODS: A retrospective case-controlled cohort analysis of patients with nonsyndromic metopic craniosynostosis was performed. Craniometric angles, distances to landmarks from midline, cephalic index, and segmented volume ratios were calculated...

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...
