Abstract: This article describes a retrospective study that compared the results obtained in a group of nine cochlear implanted otosclerotic patients with a group of nine cochlear implant (CI) patients not affected by otosclerosis. Otosclerosis patients showed signs of cochlear ossification both on high resolution computed tomography scans and intraoperatively. The incidence of facial nerve stimulation was higher in the otosclerosis group (three out of nine)and generally was related to the use of electrical stimulation from the Nucleus 22 cochlear implant. Psychophysical and speech perception measures did not show significant differences between the two groups, even though some otosclerosis patients showed increased electrical thresholds and comfort levels and slightly poorer speech perception performance scores. The authors conclude that patients with otosclerosis who have progressed to profound hearing loss derive significant benefit from cochlear implants; however, an increased risk of cochlear ossification and facial nerve stimulation has to be taken into account during preoperative counseling. 1 figure. 4 tables. 8 references.

Vestibular Schwannoma in the Only Hearing Ear: Cochlear

Implant or Auditory Brainstem Implant?

Author(s): Ramsden, R. Source: Otology & Neurotology. 26(2):261-264, March 2005. Availability: Available from Lippincott Williams and Wilkins. Customer Service, P.O. 1175, Lowell, MA 01853. (978) 262-9611. Fax: (978) 262- 9617. Language: English. Abstract: This study was conducted to explore circumstances where the patient develops a vestibular schwannoma in the only hearing ear, the other having been deaf from birth, and to consider the choice between auditory rehabilitation using a cochlear implant (CI) on the congenitally deaf side and an auditory brainstem implant (ABI) on the tumor side. Based on their findings, the authors conclude that results from cochlear implantation in the congenitally deaf ear in these patients were poor and suggest that stimulus deprivation in the early stages of the maturation of the auditory pathways is important even for a unilateral hearing loss. The authors advocate the insertion of an ABI at the time of tumor removal, retaining the option of CI in the congenitally deaf ear in the event of a poor outcome with the ABI.

The Prospect of a Biological Treatment for Restoring Hearing.

Author(s): Raphael, Y. Source: Hearing Loss. Bethesda, MD. 26(2):32. March/April 2005.

Language: English. Abstract: An overview of new research that, according to the author, will have a positive impact on the future of hearing restoration. Much of the research is centered on a lack of spontaneous cell replacement or cell regeneration in the sensory hearing epithelium. The author explains this lack as the main reason for profound deafness. Subject Category: Hearing. Descriptors: Hearing Loss. Sensorineural Hearing Loss. Hearing Loss Research.

Web site: www.ear-hearing.com. Language: English. Abstract: This article reports on a study in which environmental sound reception was studied in 11 subjects with cochlear implants using an identification test employing closed sets of ten sounds in four different environmental settings. Performance on the identification task (which was similar across the four stimulus sets) varied substantially across subjects. Mean scores ranged from 45 to 94 percent correct across the 11 subjects. Performance on the environmental sound identification test was roughly related to monosyllabic word recognition ability. Specifically, those subjects with NU-6 word scores greater than 34 percent correct performed at levels of 80 to 94 percent correct on the environmental sound test, while subjects with word scores less than 34 percent had environmental sound scores in the range of 45 to 75 percent. An analysis of confusion patterns indicated that temporal envelope cues appeared to distinguish those stimuli that were most perceptually salient. Results suggest the usefulness of a clinical screening test for environmental sound recognition. Subject Category: Hearing. Descriptors: Sound Reception. Cochlear Implants. Hearing Devices. Deafness.

Telecoils: Issues and Relevancy.

Author(s): Ross, M. Source: Seminars in Hearing. 26(2):99-108. May 2005. Availability: Reprints available from Mark Ross, Communication Sciences Department, University of Connecticut, 9 Thomas Drive, Storrs, CT 06268. Language: English. Abstract: What a hearing aid user hears through a telecoil via inductive coupling is as important as what he or she hears via the microphone, yet many audiologists and the hearing aid industry in general have not put much time and energy into either the advancement of telecoil circuitry or the proper fitting of the circuit. This article addresses issues related to telecoils, including coupling techniques for telephones and assistive listening system (ALS) receivers, the inclusion of telecoil measurements in American National Standards Institute standard S3.22 (1996), methods for telecoil evaluation, and the current status of telecoils for both telephone communication and as ALS receivers. 11 figures. 13 references.
