.... Materials and Methods: Eight donor temporal bone specimens were dissected endoscopically. For 29 healthy persons (17 males and 12 females), CT images of the temporal bone (57 ears) were taken, 3-dimensional (3-D) reconstruction and multidimensional plane reconstruction were performed, and identification...

...Jose Fernando Polanski; Lucas Resende Lucinda; Thomas Linder Imaging data provided by computed tomography scans of the temporal bone are fundamental for both the diagnosis and treatment of diseases affecting this complex structure. Despite its importance, the expertise required to analyze this exam...

... to be aware of this entity, and its relative anatomy, to avoid any unexpected complication. We present a case of a 7-year-old girl who presented with right-sided microtia with membranous atresia. Methods: High-resolution computed tomographic scan and three-dimensional reconstruction of the temporal bone...

..., opacified tympanic membrane, cholesteatoma, temporal bone fractures and glomus tumors. We discuss the indications and benefits of imaging in each of these pathologies. Results: Preoperative imaging shows interesting features and can be very helpful in the differential diagnosis and in surgical decision...

...Tetsuo Himi; Akikatsu Kataura; Motomichi Sakata; Yoshihiro Odawara; Jun-ichi Satoh; Masakatsu Sawaishi Recent advanced techniques for the reconstruction of three-dimensional (3D) images allow further visual recognition of the fine structures of the temporal bone. We demonstrate the advantages...

...Catharina Jacobsson; Gösta Granström Malformations of the cranial base, temporal bone and middle ear were induced in the offspring of Sprague-Dawley rats by a single intraperitoneal injection of 10–30 mg/kg etretinate (Tigasone®) at days 8.5–10.5 of gestation. By differential staining...

...Fatih R. Balyan; Refik Caylan; Asim Aslan; Ali Titiz; Abdelkader Taibah; Alessandra Russo; Mario Sanna Morphometric evaluation of the infralabyrinthine approach to the internal auditory canal (IAC) was performed using 20 fresh human temporal bones in order to assess the exposure limitations...

...Toshio Yoshihara; Makoto Igarashi A case of metastatic fibrosarcoma of the temporal bone was studied histopathologically. The primary site of this tumor was the posterior neck region. The initial major symptom of the patient was a left facial nerve paralysis. Although the patient underwent...

...Wendell Todd The association of abnormal tympanic membrane appearance with minimal pneumatization of the temporal bone was studied in 28 unilateral formalin-fixed cadaver specimens. The photographic appearance of each tympanic membrane was judged by seven otolaryngologists, and a normalcy score...

...Silviu Zelig; Amos Eilon; Elimelech Deutsch; I. Ariel True giant cell tumor of the temporal bone is a rare entity. This is only the 15th case documented in the English literature. It is interesting because of its presenting symptoms similar to those of external otitis. 11 12 1981 5 02...

... of endolymph which may be due to an obstruction of the endolymphatic duct and sac, located in the vestibular aqueduct (VA). Non-visualization or narrowing of the latter have been demonstrated by conventional tomography. Also, sclerosis and hypoplasia of the retrolabyrinthine portions of the temporal bone have...

...O. Westergaard; P. Kluyskens; H.D. John Alport’s syndrome is reviewed in historical retrospect. Previous histological studies of temporal bones are carefully reviewed and compared with the present findings in light microscopy of 5 temporal bones (3 patients). It is concluded that as yet there have...

...J. Dürrer; J. Zemek; J. Bušek The mechanical changes in the tissue of the temporal bone due to experimental blunt and sharp injuries to the monkey’s skull have been studied with a tensometer. These changes of the bone tissue following a blunt injury were found to be greater than those following...

...Thomas Frisch; Poul Bretlau; Mads Solvsten Sorensen Purpose of the Study: To verify microcracks in human temporal bones by a method which distinguishes intravital lesions from artifacts, to revisit previous information derived from decalcified materials on their morphology and classification...

...J.J. Manni; P.A.A. Pauwels; D.M.K.V. Creytens Two patients with a highly destructive histologic nondysplastic squamous epithelial lesion of the temporal bone are described. Both tumors were characterized by the production of copious amounts of keratin material which progressively extended...

...Mark Stenzel; Simon Preuss; Lisa Orloff; Peter Jecker; Wolf Mann Background: Cerebrospinal fluid (CSF) leaks of the temporal bone region require surgical treatment as they pose life-threatening risks such as meningitis. Aim: The aim of the study was to determine the surgical outcome depending...

...Mamoru Suzuki; Yasuo Ogawa; Akira Hagiwara; Hiroya Yamaguchi; Hidenori Ono The anatomy of the temporal bone is extremely complicated. If a three-dimensional model could be simulated, it would greatly contribute to the stereoscopic understanding of anatomy and surgery. A simulated three-dimensional...

...Spiros Manolidis; Bobby Williamson; Ling-Ling Chan; Katherine H. Taber; L. Anne Hayman Objectives: To demonstrate the utility of high-resolution computed tomography (HRCT) reconstructed in non-orthogonal planes in the planning of temporal bone surgery. Study Design: Qualitative and quantitative...

...Mads S. Sørensen; Andy B. Dobrzeniecki; Per Larsen; Thomas Frisch; Jon Sporring; Tron A. Darvann High-fidelity computer-based modeling, simulation and visualization systems for the study of temporal bone anatomy and training for middle ear surgery are based on a sequence of digital anatomical...
