Background: The last decades have witnessed remarkable progress in the field of endoscopic skull base surgery. The nose has become an established route for addressing different skull base lesions. The reconstruction after resection is a critical step for optimum surgical outcome. Objective: Evaluation of the difference in the clinical outcomes between the use of vascularized flaps and free graf...

Plastic skull models of seven individual patients were fabricated by stereolithography from three-dimensional data based on computed tomography bone images. Skull models were utilized for neurosurgical planning and simulation in the seven patients with cranial base lesions that were difficult to remove. Surgical approaches and areas of craniotomy were evaluated using the fabricated skull models...

BACKGROUND Infantile cortical hyperostosis is characterised by hyperirritability, acute inflammation of soft tissue, and profound alterations of the shape and structure of the underlying bones, particularly the long bones, mandible, clavicles, or ribs. CASE PRESENTATION We report on a clinical case of a 3-months-old baby girl of non-consanguineous parents. Multiple long bone swellings were th...

BACKGROUND Some problems have been found in the usually adopted combined approach for the removal of intra-extracranial tumors in skull base. Herein, we described a pure endoscopic transnasal or transoral approach (ETA) for the removal of intra-extracranial tumors in various skull base regions. METHODS Retrospectively, clinical data, major surgical complications, pre- and postoperative images...

Introduction A substantial body of literature has been devoted to the distinct characteristics and surgical options to repair the skull base. However, the skull base is an anatomically challenging location that requires a three-dimensional reconstruction approach. Furthermore, advances in endoscopic skull base surgery encompass a wide range of surgical pathology, from benign tumors to sinonasal...

The problem human face shape reconstruction basing on information about human skull is very important for many applications beginning with archeology and finishing with crime expertise. World recognition was received with a face shape reconstruction technique proposed by M. Gerasimov [1]. This method up to now is the general method for face reconstruction of unknown person. It operates with the...

High intensity transcranial focused ultrasound is an FDA approved treatment for essential tremor, while low-intensity applications such as neurostimulation and opening the blood brain barrier are under active research. Simulations of transcranial ultrasound propagation are used both for focusing through the skull, and predicting intracranial fields. Maps of the skull acoustic properties are nec...

Comparative studies of ontogenies of closely related species provide insights into the mechanisms responsible for morphological diversification. Using geometric morphometrics, we investigated the ontogenetic dynamics of postlarval skull shape and disparity in three closely related crested newt species. The skull shapes of juveniles just after metamorphosis (hereafter metamorphs) and adult indiv...

OBJECTIVE To determine the test performance characteristics for point-of-care ultrasound performed by clinicians compared with computed tomography (CT) diagnosis of skull fractures. METHODS We conducted a prospective study in a convenience sample of patients ≤21 years of age who presented to the emergency department with head injuries or suspected skull fractures that required CT scan evaluat...

In this paper, we present a comprehensive framework to detect morphological changes in skull vaults of adolescent idiopathic scoliosis girls. To our knowledge, this is the first attempt to use a combination of medical knowledge, image analysis techniques, statistical learning tools, and scientific visualization methods to detect skull morphological changes. The shape analysis starts from a reli...
