Bone fusion in normal and pathological development is constrained by the network architecture of the human skull [PDF]

open access: yesarXiv, 2016
The premature fusion of cranial bones, craniosynostosis, affects the correct development of the skull producing morphological malformations in newborns. To assess the susceptibility of each craniofacial articulation to close prematurely, we used a network model of the skull to quantify the link reliability (an index based on stochastic block modeling ...

Heterogeneous Angular Spectrum Approach for Trans-skull Imaging and Focusing [PDF]

open access: yes, 2019
Ultrasound, alone or in concert with circulating microbubble contrast agents, has emerged as a promising modality for therapy and imaging of brain diseases. While this has become possible due to advancements in aberration correction methods, a range of applications, including adaptive focusing and tracking of the microbubble dynamics through the human ...

Skull base chordomas review of current treatment paradigms

open access: yesWorld Journal of Otorhinolaryngology-Head and Neck Surgery, 2020
Background: Chordomas are locally invasive neoplasms, arising from notochordal remnants and can appear anywhere along the axial skeleton. Local recurrences are common, and distant metastases may occur years after the initial presentation.

Research on mouse brain tissue optical model based on Monte Carlo [PDF]

open access: yesarXiv, 2020
We studied the transmission of photons in mouse brain in both with and without intact skull states using Monte Carlo method. Photon track, optical absorption density and fluence rate were used as indicators for analysis. We found that, the photon distribution without intact skull goes farther in both longitudinal and transverse directions compared with

Functional Reconstruction of Temporomandibular Joint after Resection of Pigmented Villonodular Synovitis with Extension to Infratemporal Fossa and Skull Base: A Case Report

open access: yesThe Surgery Journal, 2016
Introduction Pigmented villonodular synovitis (PVNS) is a benign but aggressive lesion arising from sinovia. The temporomandibular joint (TMJ) is hardly ever involved.

Chondromyxoid Fibroma of the Skull Base and Calvarium: Surgical Management and Literature Review

open access: yesJournal of Neurological Surgery Reports, 2016
Chondromyxoid fibroma (CMF) is an exceedingly rare tumor that represents less than 1% of all primary bone neoplasms. Occurrence in the facial and cranial bones is extremely rare and frequently misdiagnosed.

Skull-stripping for Tumor-bearing Brain Images [PDF]

open access: yesarXiv, 2012
Skull-stripping separates the skull region of the head from the soft brain tissues. In many cases of brain image analysis, this is an essential preprocessing step in order to improve the final result. This is true for both registration and segmentation tasks.

False lateralazing sign in skull base tumor a case series of five patients

open access: yesInterdisciplinary Neurosurgery, 2021
Paradoxical neurological signs constitute a very important clinical entity for physicians to be aware of and they are of paramount importance to bear in mind in-order to avoid confusion when diagnosing lesions based on anatomic localization.
