of the tube, as well as of its anterior and posterior lips. Walker Wood has recorded an analysis of the nasopharyngeal findings in about 650 cases examined, and his results are instructive and valuable. There were forty abnormalities, in fifteen the Eustachian tubes being bifid, and in three there were adventitious openings. He figures cases of mucous polypus in the mouth of the tube, fibroma o...

The insertion of an intrascalar electrode array during cochlear implantation causes immediate damage to the inner ear and may result in delayed onset of additional damage that may interfere with neuronal stimulation. To date, there have been reports on fewer than 50 temporal bone specimens from patients who had undergone implantation during life. The majority of these were singlechannel implant...

INTRODUCTION When summarizing the performance achieved by users of a cochlear prosthesis, results are typically reported as means and standard deviations of speech recognition scores1 (also Brimacombe and Beiter, unpublished observations, 1992). These statistics constitute a valid description of the data only when scores are distributed normally, ie, as a bell-shaped On the basis of theoretical...

Initial results with the two-formant speech-processing strategy (FOFIF2) confirm the advantage of a multichannel cochlear prosthesis capable of stimulating at different sites within the cochlea. The successful presentation of two spectral components by varying the place of stimulation leads to the possibility of presenting further spectral information in this manner. Because virtually all multi...
