A new scoring system for predicting extent of resection in medial sphenoid wing meningiomas based on three-dimensional multimodality fusion imaging

open access: yesChinese Neurosurgical Journal, 2020
Background Three-dimensional (3D) fusion imaging has been proved to be a promising neurosurgical tool for presurgical evaluation of tumor removal. We aim to develop a scoring system based on this new tool to predict the resection grade of medial sphenoid

Epiphora: A Structured Diagnostic Approach for the Otolaryngologist

open access: yesWorld Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Introduction Epiphora, or excessive tearing, has historically been predominantly managed by ophthalmologists. However, as there is substantial overlap between ophthalmic and otolaryngologic anatomy and pathology that may contribute to epiphora, patients with this symptom often present to otolaryngologists as well.

AI‐Based Automated Instrument Tracking During Endoscopic Skull Base Surgery: A Pilot Feasibility Study

open access: yesWorld Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Background Endoscopic endonasal approaches (EEA) to skull base tumors are a technically challenging procedure for both surgeons and trainees. Artificial intelligence and computer vision (CV) may offer an objective analysis that provides surgical assessment on technique and enhanced educational feedback for surgeons of all levels.

Subtle Manifestation of Lower Cavernous Sinus Syndrome as the Initial and Sole Presentation of Pterygopalatine Squamous Cell Carcinoma Invasion from the Skull Base: A Case Report

open access: yesActa Neurologica Taiwanica
We present a case highlighting the critical role of early recognition of partial cavernous sinus syndrome (CSS), as diagnostic delay can lead to irreversible tumor progression.

125 years of exploration and research at Gough's Cave (Somerset, UK) 125 ans d'exploration et de recherches à Gough's Cave (Somerset, Royaume‐Uni)

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
Our understanding of the recolonization of northwest Europe in the period leading up to the Lateglacial Interstadial relies heavily on discoveries from Gough's Cave (Somerset, UK). Gough's Cave is the richest Late Upper Palaeolithic site in the British Isles, yielding an exceptional array of human remains, stone and organic artefacts, and butchered ...

Neuroanatomy of the Cavernous and Sphenoid Sinus

open access: yes, 1990
The cavernous sinus was described by Ridley (1695), but Winslow In 1732 noted fibrous trabeculae and likened the structure\u27s interior to the corpus cavernous of the penis; he used the term cavernous which has persisted.

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

open access: yesIntegrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...
