OBJECTIVE With broadening candidacy criteria for cochlear implantation, a greater number of pediatric candidates have usable residual hearing in their nonimplanted ears. This population potentially stands to benefit from continued use of conventional amplification in their nonimplanted ears. The purposes of this investigation were to evaluate whether children with residual hearing in their noni...

OBJECTIVES/HYPOTHESIS To investigate the impact of hearing aid and cochlear implant use on quality of life in adults. STUDY DESIGN Prospective observational cohort study. METHODS One hundred thirteen adults aged ≥50 years with postlingual hearing loss receiving routine clinical care at a tertiary academic medical center were evaluated with the Medical Outcome Study Short Form-36 before and ...

BACKGROUND Considered a rare disorder, superficial siderosis of the central nervous system (SSCN) has become more frequently diagnosed in recent years. As it is characterized by progressive sensorineural hearing loss, patients' needs may surpass the capability of hearing aid technology. Despite the retrocochlear nature of the disorder, patients have undergone cochlear implantation (CI) with var...

Objective To investigate the contributions of envelope and fine-structure to the perception of timbre by cochlear implant (CI) users as compared to normal hearing (NH) listeners. Methods This was a prospective cohort comparison study. Normal hearing and cochlear implant patients were tested. Three experiments were performed in sound field using musical notes altered to affect the characterist...

The purpose of this case study was to determine whether the P1-N1-P2 acoustic change complex (ACC) could be recorded in an individual with a cochlear implant. In a cochlear implant recipient, stimulus-related artifact from the implant can overlap the evoked potential of interest, making it difficult to determine whether the recorded response is neural or a simple reflection of the artifact. Thi...

Combined electric and acoustic stimulation (EAS) of the auditory system is a new therapy for patients with severe to profound high- and mid-frequency hearing loss but remaining low-frequency hearing. In a prospective study, 13 patients with low-frequency hearing of better than 60 dB below 1 kHz were implanted with a MED-EL COMBI 40+ cochlear implant. Pure tone thresholds as well as monosyllabic...

This critical review examines literature that has addressed the question: Are there successful predictors of cochlear implant outcomes in children with auditory neuropathy spectrum disorder (ANSD)? Through a search of the current literature, four studies were included for critical analysis. Study designs included one nonrandomized retrospective cohort study, one nonrandomized longitudinal cohor...

BACKGROUND Skin flap failure is a significant, though relatively uncommon complication of cochlear implant surgery. To achieve a good surgical result, a proper plan to locate the prospective implant is required. Thus, a new design of flap was evaluated in this regard. METHODS Two hundred and eleven consecutive children undergoing cochlear implantation in Baqiyatallah Cochlear Implant Center w...

Copyright © 2007 Massachusetts Medical Society. A 4-month-old baby girl whose parents and 6-year-old brother have severe-to-profound sensorineural hearing loss is referred for consideration for cochlear implantation. Each of the baby’s parents had previously received a cochlear implant in adulthood, and her older brother had received a cochlear implant at 18 months of age. The family uses oral ...
