First results of a novel adjustable-length ossicular reconstruction prosthesis in temporal bones.
OBJECTIVES/HYPOTHESIS The performance of an ossicular replacement prosthesis (ORP) is influenced by its alignment and appropriate tension between the tympanic membrane and the stapes footplate. A novel ORP with a flexible element that potentially allows for length adjustment in situ is presented and tested for acoustic performance. STUDY DESIGN Laser Doppler vibrometry in fresh human cadaveri...
متن کاملDual immunofluorescence staining of proteoglycans in human temporal bones.
OBJECTIVES/HYPOTHESIS Immunofluorescence staining methods have been developed to study the distribution of macromolecules in archival formalin-fixed celloidin-embedded human temporal bone tissues. The aim of this study was to investigate the feasibility of utilizing this approach to evaluate the codistribution of more than one molecule of interest in a single tissue section. STUDY DESIGN Retr...
متن کاملSpontaneous Bilateral Meningoencephalocoeles of the Temporal Bones
Spontaneous tegmen tympani defects are rare with even rarer bilateral cases. The symptoms are nonspecific; hence, a high index of suspicion is required to prevent serious intracranial complications. We present a case of spontaneous bilateral tegmen tympani defects with associated meningoencephalocoeles in a 54-year-old male who presented with the signs and symptoms of severe meningitis. After c...
متن کاملDifferential Intracochlear Sound Pressure Measurements in Human Temporal Bones with an Off-the-Shelf Sensor
The standard method to determine the output level of acoustic and mechanical stimulation to the inner ear is measurement of vibration response of the stapes in human cadaveric temporal bones (TBs) by laser Doppler vibrometry. However, this method is reliable only if the intact ossicular chain is stimulated. For other stimulation modes an alternative method is needed. The differential intracochl...
متن کاملCorrelation between histologic and radiographic reconstruction of intracochlear electrode position in human temporal bones.
In our laboratory, human temporal bone specimens from patients who in life have undergone cochlear implantation are routinely processed with the implant in situ, embedded in Araldite, sectioned at 20 µm and serially photographed during cutting, stained with toluidine blue and mounted on glass slides. From the images, two-dimensional and three-dimensional reconstructions can be made and a very a...
