Temporal Bone Drilling Simulation Boot Camp Course
… a novice learners’: (i) understanding of the temporal bone anatomy as demonstrated by a significant difference between pre- and post-intervention knowledge testing (p < 0.01), (ii) drilling technique, as demonstrated by a significant difference between pre- and post-intervention drilling …

Computer microvision measurements of stapedial motion in human temporal bone
Thesis (S.B. and M.Eng.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 1998.

Analysis of the Physical and Physiological Events Resulting from Caloric Irrigation of the Human Temporal Bone
… a study of horizontal serial sections of human temporal bones showed that the most direct anatomical route from the external auditory meatus to the lateral semicircular canal is through the air of the middle ear cleft. The bony posterior-inferior extension of the external meatus, which has been …

Study on the development of the mouse ossicles using Micro-CT
… on how ossicles change in the developing temporal bone would be helpful in understanding biomechanical knowledge of ossicles. In this study, three dimensional structural images of mouse were investigated through Micro-CT to understand developmental anatomy of its ossicles. Additionally, …

Clinical and Molecular Characterization of Auditory Neuropathy
… until adulthood when other symptoms appear. A temporal bone study of an MTS patient showed near complete loss of spiral ganglion cells, but preservation of the organ of Corti. NSRAN individuals with OTOF mutations benefit from cochlear implantation. No one with MTS is known to have been …

Development of image-based surgical planning software for bone-conduction implants
The BONEBRIDGE bone-conduction device is used to treat conductive and mixed hearing losses. The size of its floating mass transducer (FMT) can preclude implantation in certain anatomies, necessitating comprehensive surgical planning. Current techniques are time consuming and difficult to transfer …

Genetic analyses, protein expression, type and function with clinical and immunological correlates in human papillomavirus associated head and neck neoplasia
… of squamous cell carcinoma within the temporal bone region. This is an uncommon tumour which is normally preceded by a history of inflammation within the external auditory canal (EAC) or middle ear / mastoid cavity. Although HPV has been implicated in many head and neck malignancies, …

Effects of Electrical Stimulation and Testosterone in Translational Models of Facial Nerve Injury
… can be appropriately investigated. The extratemporal facial nerve axotomy model, in which the nerve is crushed at its exit from the skull, has been well established in the past and used to study the regeneration program of motoneurons. The present study uses this rat injury model to evaluate …

Multimedia Educational Resource of the Temporomandibular Joint for Dental Students
… joint formed by the squamous portion of the temporal bone and the condyle of the mandible. The TMJ forms two synovial joints which are structurally supported by the mandibular condyle, joint capsule, an articular disc and supporting ligaments. The main arterial components of this region are …

Computational Models Explaining Cochlear Implant Principles: A Hypothesis, Applications and Physical Validations
… focuses on validating these models against human temporal bone specimens for evaluating the accuracy of computational methods. Chapter 3 develops a comprehensive head model that sheds light on how CIs affect neural pathways and electric field intensities, with a special focus on the IAM. This …

Migration of human tympanic epithelium in health and disease
… by Cruveilhier (1829) as a pearly tumour of the temporal bone and a few years later (1838) by Johannes Muller.

Radiotherapy for head and neck paragangliomas: A 10 year retrospective review 2005-2014 at Groote Schuur Hospital and UCT Private academic hospital
… group developed osteonecrosis of the temporal bone at 5 year follow up. Conclusion. Radiosurgery and radiotherapy are efficacious in achieving tumour control with minimal morbidity. Tumour control rates in the study are similar to control rates in literature. Radiation associated …

Resorption rate tunable bioceramic: Si,Zn-modified tricalcium phosphate
<p>An ideal bone implant material would support the activity of osteoblasts in the development of new bone, while simultaneously being resorbed by osteoblasts as part of the lifelong orderly process of bone remodeling. Silicon and Zinc modified tricalcium phosphate (Si,Zn-TCP), a biphasic material, …

Middle-Ear Imaging and Estimation of The Linear Elastic Properties of The Human Tympanic Membrane
… membrane (TM). In the imaging study, six human temporal bones were used, which were obtained in right-left pairs, from three cadaveric heads. All bones were fixed using formaldehyde. Only one bone from each pair was stained using IKI solution. Samples were scanned using a micro-computed …

Functional measurements of ear pathology in patients and cadaveric preparations
… performance were also measured in human temporal bone preparations with simulated pathologies similar to those in the patient populations. Reflectance was also measured up to a higher frequency than had previously been possible using an experimental acoustic reflectance measurement …

Treatment of early middle ear cholesteatoma by atticosinoplasty
… 120 cases of relatively small cholesteatoma on temporal bone tomography were comparatively analysed for hearing improvement with 35 cases of mastoid obliteration and 110 cases of open cavity mastoidectomy. We analysed results according to the type of cholesteatoma and ossiculoplastic materials. …

Role of downstream signal transduction molecules of congenital middle ear cholesteatoma according to its site of origin
… analysing the findings of eardrum, operation and temporal bone computed tomograpy. By RT-PCR and immunohistochemical techniques, we investigated the reaction patterns of antibodies to PLC-γ1, EGFR, PDGFR-α, PDGFR-β, and PI3 kinase as the proliferation and differentiation markers in 10 human …
