BACKGROUND The advent of universal neonatal hearing screening in some countries and the availability of screening programs for at-risk infants in other countries has facilitated earlier referral, diagnosis, and intervention for infants with hearing loss. Improvements in device technology, two decades of pediatric clinical experience, a growing recognition(More)
OBJECTIVE The aim was to assess articulation and speech intelligibility over time in a group of cochlear implant users implanted at 8 yr or over. The hypothesis was that the postoperative speech production performance would be greater than the preoperative performance. DESIGN A test of intelligibility using sentences and an articulation test measuring(More)
BACKGROUND Previous research suggests that children with pure-tone averages of greater than 90 dB hearing level and/or open-set sentence perception of less than 30% may derive significant benefit from cochlear implantation. OBJECTIVE To evaluate postoperative speech perception benefit and bilateral-bimodal benefit for 16 children whose preimplant speech(More)
OBJECTIVES The aim was to measure the rate of vocabulary acquisition for cochlear implant users and compare the pre- and postoperative rates with published data for other groups with normal or impaired hearing. The hypothesis was that the postoperative rate would be greater than the preoperative rate. DESIGN The Peabody Picture Vocabulary Test (PPVT) was(More)
A group of 10 children, adolescents, and prelinguistically deafened adults were implanted with the 22-electrode cochlear implant (Cochlear Pty Ltd) at the University of Melbourne Cochlear Implant Clinic and have used the prosthesis for periods from 12 to 65 months. Postoperative performance on the majority of closed-set speech perception tests was(More)
OBJECTIVE Many reports have established that hearing-impaired children using the Nucleus 22-channel cochlear implant may show both significant benefits to lipreading and significant scores on open-set words and sentences using electrical stimulation only. These findings have raised questions about whether severely or severely-to-profoundly deaf children(More)
OBJECTIVE Describe the long-term benefits of early cochlear implantation. Provide a comprehensive description of outcomes, including: language, speech production, and speech perception. Compare the communication outcomes for the early implanted children to those of normally hearing children and children who received a cochlear implant at a comparatively(More)
OBJECTIVES The aim of this study was to develop guidelines, based on the unaided pure-tone audiogram, for recommending a cochlear implant (CI) for infants and young children with residual hearing. As awareness of the benefits of early implantation increases and age at diagnosis decreases, an increasing number of infants are presenting for consideration of(More)
A group of 102 children using the Nucleus multichannel cochlear implant were assessed for open-set speech perception abilities at six-monthly intervals following implant surgery. The group included a wide range of ages, types of hearing loss, ages at onset of hearing loss, experience with implant use and communication modes. Multivariate analysis indicated(More)
OBJECTIVE Examine the influence of age at implant on speech perception, language, and speech production outcomes in a large unselected paediatric cohort. STUDY DESIGN This study pools available assessment data (collected prospectively and entered into respective databases from 1990 to 2014) from three Australian centers. PATIENTS Children (n = 403) with(More)
