Augmented Reality of the Middle Ear Combining Otoendoscopy and Temporal Bone Computed Tomography
2018
International audience; HYPOTHESIS:Augmented reality (AR) may enhance otologic procedures by providing sub-millimetric accuracy and allowing the unification of information in a single screen.BACKGROUND:Several issues related to otologic procedures can be addressed through an AR system by providing sub-millimetric precision, supplying a global view of the middle ear cleft, and advantageously unifying the information in a single screen. The AR system is obtained by combining otoendoscopy with temporal bone computer tomography (CT).METHODS:Four human temporal bone specimens were explored by high-resolution CT-scan and dynamic otoendoscopy with video recordings. The initialization of the system…
MRI of the inner ear: use of modified GRASS and fast spin-echo sequences
1996
We report our experience with MRI of the normal and pathological inner ear with fast spin-echo and modified gradient recalled at steady state sequences. Although earlier studies on temporal bone MRI were discouraging, improvements in MR technology combined with the use of paramagnetic contrast media can make MRI a useful diagnostic tool for the assessment of inner ear pathology. Conventional spin-echo imaging seems not to be the modality of choice because of the relatively thick slices and the long acquisition times.
Top-cited articles in cerebrospinal fluid leak (rhinorrhea and otorrhea) (1945–2018)
2021
Abstract Introduction: As scientific knowledge has grown in biomedicine, it has also become necessary to develop tools to manage and understand the body of evidence. In that sense, bibliometrics has become a consolidated discipline for analyzing scientific activity, enabling the characterization of a particular field or area of knowledge by means of the quantification of the bibliographic characteristics of scientific publications. Objective: The objective of this study was to determine the most frequently cited articles in the field of cerebrospinal fluid rhinorrhea and otorrhea. Methods: The searches took place on the Clarivate Analytics Web of Science platform, which includes the MEDLINE…
Ungewöhnlicher Verlauf von otobasalen Frakturen mit Liquorrhoe*
1993
In the literature the persistence of cerebrospinal Liquorrhea after temporal bone fractures is a rare event. Between 1989 and 1992 four cases of temporal bone fractures with dural involvement were operated at the University ENT Department Mainz. These temporal bone fractures showed delayed or persistent symptoms of dural lacerations between three and sixty months after head injury. During operation we found larger bone-dura defects (1-1.5 cm in diameter) and brain herniations in all cases. Strohm stated that only in rare cases a temporal bone fracture produced a larger gap in the tegmen tympani or antri. Therefore, we assumed that in our cases such larger bone-dura defects were caused by a …
Beidseitige progrediente Hörminderung als Erstmanifestation eines metastasierenden Pankreaskopfkarzinoms - Kasuistik -
2001
We report the history of a patient who presented first with a progressive unilateral hearing loss and later with a bilateral deafness and an unilateral facial nerve palsy as first and only symptoms of a pancreatic adenocarcinoma. By means of magnetic resonance tomography tumor-suspect lesions in both internal auditory canals were detected. Referring to the results of further examinations these intracanalicular lesions are most probably due to rarely seen bilateral metastasis of a pancreatic adenocarcinoma in the temporal bone. In addition to this rarely diagnosed localisation of metastasis it is rather uncommon that this kind of primary malignoma had not been detected because of gastrointes…
