INTRODUCTION  The cochlear implant is a device that is intended to substitute for the function of cochlear hair cells, electrically stimulate auditory nerve fibers, and contribute to the perception of speech sounds. However, the surgical procedure alone is not enough for the user to achieve favorable results in habilitation/rehabilitation. OBJECTIVE  To characterize the patients from Manaus w...

OBJECTIVES/HYPOTHESIS Determining cochlear implant candidacy requires a specific sentence-level testing paradigm in best-aided conditions. Our objective was to determine if findings on routine audiometry could predict the results of a formal cochlear implant candidacy evaluation. We hypothesize that findings on routine audiometry will accurately predict cochlear implant evaluation results in th...

OBJECTIVE Both clinical data and laboratory studies demonstrated the risk of pneumococcal meningitis post-cochlear implantation. This review examines strategies to prevent post-implant meningitis. DATA SOURCES Medline/PubMed database; English articles after 1980. Search terms: cochlear implants, pneumococcus meningitis, streptococcus pneumonia, immunization, prevention. REVIEW METHODS Narra...

The present study 1) examined speech recognition at three intensity levels and in noise for adults with bilateral hearing loss who wore amplification and were referred for cochlear implant evaluation but did not meet current audiological criteria, and 2) compared their performance to cochlear implant recipients using current implant technology. When tested at 70 dB SPL, hearing aid subjects' wo...

OBJECTIVE To monitor cochlear function by extra- and intra-cochlear electrocochleography (ECoG) during and after cochlear implantation and thereby to enhance the understanding of changes in cochlear function following cochlear implantation surgery. METHODS ECoG responses to acoustic stimuli of 250, 500 and 1,000 Hz were recorded in 9 cochlear implant recipients with presurgical residual heari...

• We have developed a facility that enables scientists to investigate a wide range of sound-processing schemes for human subjects with cochlear implants. This digital signal processing (DSP) facility-named the Programmable Interactive System for Cochlear Implant Electrode Stimulation (PISCES)-was designed, built, and tested at Lincoln Laboratory and then installed at the Cochlear Implant Resear...

Recalcitrant chronic infections of implanted medical devices are often linked to the presence biofilms. The prevention and treatment device-associated is a major source antibiotic use driver antimicrobial resistance globally. Lowering incidence infection in patients that receive could therefore significantly improve stewardship reduce patient morbidity. Here we determined if modifying design an...
