OBJECTIVES: Fibrous dysplasia of bone is a rare sporadic benign congenital condition in which normal cancellous bone is replaced by fibro-osseous tissue with immature osteogenesis. Sarcomatous transformation is exceptional. Lesions may involve one bone (monostotic) or several (polyostotic). Fibrous dysplasia may be associated with café-au-lait skin macules and endocrinopathy in McCune-Albright syndrome, or with myxoma in Mazabraud's syndrome. METHODS: We report ten cases of patients followed up for craniofacial fibrous dysplasia in our center between 2010 and 2015...

Craniosynostosis is a condition in which one or more of the cranial sutures have fused prematurely, affecting the growth pattern and contours of the infant skull. The pterion is the junction of temporal, frontal, parietal, and sphenoid bones of the skull. We present a case of unilateral pterional craniosynostosis, which was treated with strip craniectomy and helmet therapy.

BACKGROUND: Recent advances in endoscopic techniques have allowed minimally invasive approaches to the cranio-vertebral junction (CVJ) through the oropharynx (ETA) in addition to the transnasal approach (EEA). These minimally invasive endoscopic techniques allow for increased surgical exposure using no visible incisions, with a potential less morbidity. The ability to know preoperatively the limit of the ETA is vital for the surgical planning in order to better address CVJ pathology. The aim of the present study is to determine the anatomical limits of endoscopic dissection of the skull base and upper cervical spine through the transoral corridor and the superior limit reached by adopting this approach...

Crouzon syndrome (CS) is an autosomal dominant disorder characterized by craniofacial deformities caused by the early closure of cranial sutures. It is diagnosed by the presence of a flat sphenoid bone, protrusion of eyeballs (exophthalmos), and midfacial hypoplasia. Although hypodontia is usually present in cases with CS, supernumerary teeth are rarely seen. A 16-year-old male patient with CS was referred to our clinic. He had a high forehead, beaked nose, hypertelorism, palpebral ptosis, and asymmetrical orbits...

Pituitary adenomas with sphenoid sinus or clivus invasion are not uncommon, but the pathogenesis responsible for this phenomenon remains unclear. Cathepsin K, expressed predominantly in osteoclasts, can degrade type I collagen and plays an essential role in bone resorption. Recent studies reported the expression of Cathepsin K in various malignant tumors, such as bone, breast, lung and prostate cancers, and its expression is further increased in bone metastasis or invasive subpopulations. In addition, cathepsin K inhibitors (CatKi) were demonstrated to effectively prevent or reduce osteolytic lesions in breast cancers with bone metastasis...

OBJECTIVE Exposure of the cavernous sinus is technically challenging. The most common surgical approaches use well-known variations of the standard frontotemporal craniotomy. In this paper the authors describe a novel ventral route that enters the lateral wall of the cavernous sinus through an interdural corridor that includes the removal of the greater sphenoid wing via a purely endoscopic transorbital pathway. METHODS Five human cadaveric heads (10 sides) were dissected at the Laboratory of Surgical NeuroAnatomy of the University of Barcelona...

We report a case of retiform hemangioendothelioma (RH) located in the infratemporal fossa and buccal area in a 13-year-old Korean boy. The tumor originated from the sphenoid bone of the infratemporal fossa area and spread into the cavernous sinus, orbital apex, and retro-nasal area with bone destruction of the pterygoid process. Tumor resection was conducted via Le Fort I osteotomy and partial maxillectomy to approach the infratemporal fossa and retro-nasal area. The diagnosis of RH was confirmed after surgery...
