BACKGROUND AND IMPORTANCE: Liposclerosing myxofibrous tumors (LSMFTs) are rare benign fibro-osseous tumors most frequently occurring in the proximal femur. We report the first case of this rare tumor occurring within the calvarium. CLINICAL PRESENTATION: Our patient presented with a 2-yr history of enlarging, painless, fixed mass over the left forehead. She underwent surgical resection and the mass was histologically confirmed to be a LSMFT. CONCLUSION: LSMFT is a rare tumor that should remain on the differential for lesions of the calvarium...

BACKGROUND: Surgical intervention during infancy for both syndromic and nonsyndromic patients with craniosynostosis remains the criterion standard of treatment with the 2 main options being open vault remodeling versus minimally invasive surgery. Although open cranial vault remodeling was initially considered a high-risk procedure, many advances have improved its safety. Despite this, there is a paucity of literature on the long-term outcomes of contemporary open craniosynostosis repair...

OBJECTIVE: Majority of multi-suture craniosynostosis are related to single-gene disorders or chromosomal abnormalities. Children with craniosynostosis usually present at an early age due to the presence of an abnormal head shape, with the exception of a unique entity termed primary normocephalic pancraniosynostosis. The objective of this article is to describe an unusual case of primary normocephalic pancraniosynostosis, detected incidentally following an accidental head injury. A comprehensive review of the literature will also be included...

The outcome of cranial vault reconstruction for the surgical treatment of craniosynostosis heavily depends on the surgeon's expertise because of the lack of an objective target shape. We introduce a surface-based diffeomorphic registration framework to create the optimal post-surgical cranial shape during craniosynostosis treatment. Our framework estimates and labels where each bone piece needs to be cut using a reference template. Then, it calculates how much each bone piece needs to be translated and in which direction, using the closest normal shape from a multi-atlas as a reference...

Despite progress made in nasal reconstruction, the restoration of a large defect, including the whole septum and mid-nasal vault structures, remains a challenge. The pericranial flap (PCF) is used widely for the reconstruction of anterior cranial fossa defects. This article presents a surgical technique for nasal lining restoration with an endoscopic PCF design. This technique was used in patients with huge intranasal tumours. Two patients with nasal eosinophilic angiocentric fibrosis were treated. The structural involvement was similar in each case...

INTRODUCTION: Craniosynostosis, the premature fusion of ≥1 cranial sutures, is the leading cause of pediatric skull deformities, affecting 1 of every 2000 to 2500 live births worldwide. Technologies used for the management of craniofacial conditions, specifically in craniosynostosis, have been advancing dramatically. This article highlights the most recent technological advances in craniosynostosis surgery through a systematic review of the literature. METHODS: A systematic electronic search was performed using the PubMed database...

OBJECTIVE Infants with severe hydrocephalus and extreme macrocephaly typically undergo CSF diversion early in life, which can result in significant cranial deformity due to CSF overdrainage. In this scenario, overlap of the cranial plates can precede the development of secondary synostosis and/or severe, permanent cranial deformity. As a result, extensive cranial vault remodeling is sometimes undertaken later in life, which is often challenging and has been associated with mortality and a high morbidity rate...

Removal of the fronto-orbital bandeau is one of the most critical components for procedures designed to correct anomalies of the craniofacial skeleton and remodel the anterior calvarial vault. It is also used to improve exposure of the anterior cranial fossa. It is arguably one of the more difficult portions of some craniofacial procedures. While the technique for fronto-orbito-sphenoid osteotomy has been frequently described, it has only been minimally detailed. Separation of bone in this region remains challenging due to the bone thickness, adjacent vital structures, and limited direct visibility...

INTRODUCTION: Methods of reporting quantitative results for distraction osteogenesis (DO) of craniosynostosis have been inconsistent. Therefore, the efficacy of differing techniques and timing in regard to volume change is not well established, with no uniform metric for comparisons. Given that cranial vault remodeling with DO may be completed with different approaches, analysis was made to determine (1) the relative efficiency of different approaches in expanding intracranial volume (ICV) and (2) the impact of adjusting for ICV growth on measured DO efficiency...

INTRODUCTION: Timing of intervention and complication profiles in surgical repair of craniosynostosis have been widely debated. Early intervention is frequently promoted as a means of decreasing morbidity while maintaining favorable outcomes via minimally invasive techniques such as endoscopic strip craniectomy. Immediate postoperative morbidity due to complications of early vs late intervention remains a key element in comparing timing and technique for craniosynostosis repair. In addition, concurrent fronto-orbital advancement with open cranial vault remodeling may increase the risk of postoperative complications...

Crouzon syndrome (CS) is one of the craniosynostosis syndromes that leads to early fusion of cranial sutures and increased intracranial pressure. Intracranial hypertension is a serious complication that may lead to vision loss and cognitive impairment. Early detection and management are necessary to prevent complications. The authors present a patient with CS who underwent posterior cranial vault reconstruction with internal distraction after multiple episodes of headache and papilledema. The patient was unaware of any loss of color vision before the surgery; however, he noted an improvement in his color vision after the surgery...

BACKGROUND: Late treatment of scaphocephaly presents challenges including need for more complex surgery to achieve desired head shape. Virtual surgical planning for total vault reconstruction may mitigate some of these challenges, but has not been studied in this unique and complex clinical setting. METHODS: A retrospective chart review was conducted for patients with scaphocephaly who presented to our institution between 2000 and 2014. Patients presenting aged 12 months or older who underwent virtual surgical planning-assisted cranial vault reconstruction were included...

BACKGROUND: The recommended treatment for craniosynostosis, is cranial vault expansion to prevent increased intracranial pressure and optimize developmental outcomes. Some patients complain about postoperative headaches and occasionally require revision to treat increased intracranial pressure. This study examines whether specific factors are associated with an increased risk of postoperative headaches or intracranial hypertension. METHODS: This retrospective cohort included patients with craniosynostosis from 1995 and 2010...

Virtual planning of open cranial vault reconstruction is used to simulate and define an pre-operative plan for craniosynostosis surgery. However, virtual planning techniques are subjective and dependent on the experience and preferences of the surgical team. To develop an objective automated 3D pre-operative planning technique for open cranial vault reconstructions, we used curvature maps for the shape comparison of the patient's skull with an age-specific reference skull. We created an average skull for the age-group of 11-14 months...

BACKGROUND: Premature fusion of the metopic suture leads to a range of clinical presentations, with more severe patients presenting characteristically with trigonocephaly. Endoscopic-assisted correction of craniosynostosis is emerging as an alternative to the gold-standard open cranial vault remodeling. While there are several documented benefits of endoscopic correction, the management of craniosynostosis varies widely in the literature with little consensus as to the preferred timing and surgical technique for repair...

BACKGROUND: Cranial vault reconstruction (CVR) is the gold standard in the operative treatment of craniosynostosis. Full thickness osseous defects (FTOD) of the calvaria have been observed in 5% to 15% patients after CVR, with higher rates cited in the fronto-orbital advancement (FOA) subset. Particulate bone graft (PBG) harvested manually has been shown to decrease FTOD after FOA from 24% to 5.5%. The authors used a modified technique using a powered craniotome, with the hypothesis that the technique would also improve outcomes...

: Open cranial vault remodeling techniques require rigid fixation with hardware such as plates and screws; however, complications can occur. The purpose of this study was to assess the surgical outcome after open reconstruction for craniosynostosis with less rigid fixation using nonabsorbable suture. METHODS: Retrospective review of patients who underwent open craniofacial reconstruction for craniosynostosis at the Hospital Kuala Lumpur between January 2011 and December 2016 were performed...
