Diagnostic performance of the hearing handicap inventory for the elderly (screening version) against differing definitions of hearing loss.

The diagnostic performance of the Hearing Handicap Inventory for the Elderly--Screening Version (HHIE-S) was evaluated against five definitions of hearing loss in 178 elderly subjects screened in primary care. Hearing loss was assessed by pure-tone audiometry. Using a score of greater than 8 as a cut point, the HHIE-S had sensitivities ranging from 53 to 72% and specificities ranging from 70 to 84% with the different definitions. The HHIE-S receiver-operating characteristics and likelihood ratios were similar regardless of hearing loss definition used. The HHIE-S is a valid, robust test for identifying hearing-impaired elderly, irrespective of the audiometric definition used to finally diagnose hearing difficulties.

Performance and management of children with unilateral sensorineural hearing loss.

This paper reviews the status of children with unilateral sensorineural hearing loss. There is mounting evidence to show that some unilaterally hearing-impaired children experience difficulty in school. Furthermore, these children may have trouble understanding speech in noise, exhibit poor localization skills, and display behavior problems in school and at home. Suggested management strategies for this population are discussed.

Hearing, speech, and language outcome in infants with extreme immaturity.

There appears to be an increase in the number of premature infants who survive treatment in neonatal intensive care units. Such an increase is expected to result in a greater number of children with developmental delays in a variety of dimensions, including auditory and psycholinguistic abilities. This report presents hearing and speech/language data on a sample of 266 high-risk infants. The data revealed that approximately one-third of the population exhibited hearing impairment and/or speech/language problems. The need for early identification and periodic assessment with this population is emphasized.

An introduction to unilateral sensorineural hearing loss in children.

This paper offers a general review of literature on issues pertinent to unilateral hearing loss in children. The paper focuses on such areas as demographic considerations, the importance of binaural hearing, the effects of noise on speech recognition, learning and educational factors, and auditory deprivation. It is concluded that there is sufficient evidence to suspect that children with unilateral sensorineural hearing loss can experience complications in communication and education. Finally, this paper presents the description of a research plan used in our study on unilateral sensorineural hearing loss in children.

Case history data on unilaterally hearing-impaired children.

This paper presents the data from medical and educational case histories on a group of 60 unilaterally hearing-impaired children. The case history data revealed that approximately one-half of the 60 children with unilateral sensorineural hearing loss exhibited some difficulty in educational progress. More specifically, 35% had failed at least one grade and an additional 13% were in need of some special resource assistance. Similar findings were obtained on a subset of 25 unilaterally hearing-impaired children who satisfied rather stringent criteria for age, hearing level, intelligence, length of time the impairment was present, history of middle ear disease, and general growth and development.

Auditory performance of children with unilateral sensorineural hearing loss.

Horizontal sound localization and syllable recognition skills were examined in a group of children with unilateral sensorineural hearing loss and a matched group of normal hearers. The results showed that the unilaterally hearing-impaired children performed more poorly than the normal counterparts in both localization and speech recognition of nonsense syllables. The unilaterally hearing-impaired children had considerable difficulty understanding in a background of noise. The clinical implications of these findings are discussed.

Identification, assessment, and management of children with unilateral sensorineural hearing loss.

Because some unilaterally hearing-impaired children appear to experience difficulty in communication and educational progress, it seems only appropriate to reassess the identification and management strategies that are used with these children. Accordingly, this paper presents some general information on identification, assessment, and management of children with unilateral hearing loss from the perspective of three disciplines: audiology, speech-language pathology, and psychology.

Audiologic manifestations in bilateral acoustic tumors (von Recklinghausen's disease).

This report provides a review and discussion of bilateral acoustic tumors (von Recklinghausen's Disease) with emphasis on the audiological manifestations. To aid in our clinical description of this disease a series of 22 patients are summarized and three case reports are presented. The audiometric findings are shown to be quite different from what is generally seen in unilateral tumors. Because of the significant complications that can be associated with this disorder, especially in the later stages, the importance of early detection is emphasized. Strategies for audiologic management are also presented.

Unilateral hearing impairment in children.

An overview and update are offered on difficulties experienced by children with monaural sensorineural deafness. It is the general consensus that children with unilateral hearing loss experience few, if any, communication and/or educational problems. The medical and educational status of a group (N = 60) of children with unilateral, hearing impairment are described. In addition, the auditory, linguistic, and behavioral manifestations of unilateral hearing impairment were studied in considerable detail for a subsample of these 60 children. The results revealed that approximately one third of the children with unilateral hearing loss had failed at least one grade. Nearly 50% of the group had either failed a grade and/or needed resource assistance in the schools. The small subsample of children with unilateral hearing loss performed much poorer than a matched group of children with normal hearing on both a localization and a syllable recognition task. Finally, the data on behavioral and linguistic manifestations of monaural hearing loss indicate that children with unilateral hearing impairment are experiencing more problems than previously supposed.

Tutorial on the potential deterioration in hearing due to hearing aid usage.

This manuscript examines the issue of potential decline in hearing sensitivity due to hearing aid usage through an analysis of data obtained from the temporary threshold shift (TTS) paradigm. Following a critique of the traditional measures of TTS, the concept of integrated TTS (ITTS) is reviewed and data on hearing-aid-induced ITTS are presented. In addition, a series of equations relating permanent threshold shift (PTS) to a recently developed measure of noise dose (Dn) is derived and predictions for hearing-aid-induced PTS are made. Recommended gain settings established to protect the hearing of a person wearing a hearing aid from further decline following various durations of hearing aid usage are also provided.

Special auditory testing: review and update.

This report reviews the development of special auditory testing and the contribution of these procedures in neurotologic diagnosis. An evaluation of the tests comprising the traditional special auditory test battery indicates that most of them are no longer adequate to the task in that they are not sufficiently sensitive to minimal pathology of the eighth nerve. Several different auditory test methods are reviewed and recommended.

Unexplained conductive hearing loss.

We report a series of unusual clinical cases which exhibit what we have referred to as unexplained conductive hearing loss. Audiometrically, these cases typically display mild to moderate conductive or mixed-type hearing loss and good word discrimination (80% to 100%). The otologic evaluations also lend support to the audiometric findings. When polytome roentgenograms were obtained thr results showed a normal inner ear system. Most often, the otologists' clinical impression was a fixed malleus or congenital stapes fixation, and exploratory tympanotomy with inspection of the ossicular chain was recommended. In each case, the ossicular chain was found to be intact. When the incudostapedial joint was separated the malleus and incus were seen to be mobile. Further, palpation of the stapes resulted in good round window reflexes. Possible explanations for this phenomenon are considered.

Horizontal sound localization skills of unilaterally hearing-impaired children.

The present study assessed the horizontal sound localization skills of three groups of subjects; normal-hearing adults, normal-hearing children, and unilaterally hearing-impaired children. The ability of these subjects to localize pure tones to 500 and 3000 Hz in quiet and in a background of cafeteria noise was evaluated using an array of thirteen loudspeakers mounted in a large anechoic chamber. Results indicated a significant effect of signal frequency in all three groups of listeners. In addition, the hearing-impaired children performed significantly poorer than their normal-hearing counterparts in all conditions. Individual differences in sound localization ability among the hearing-impaired listeners could be explained largely through effects of age and degree of hearing impairment.

Effects of age and sensorineural hearing loss on word recognition.

Word recognition scores were compared between a younger age group (15 to 35 years) and an older age group (55 to 85 years) exhibiting similar mild sensorineural hearing losses. No differences were found between the two sets of subjects for recognition ability in quiet and only 5% in noise. Contrary to widespread belief, these results revealed no tendency for the older age group to display poorer recognition performance than the younger listeners. The importance of hearing sensitivity as well as age as a factor affecting work recognition is discussed, and comparative data from the literature are presented.

Glomus tumor of the middle ear: origin, symptomatology, and treatment.

The glomus tumor is considered to be the most common of all tumors that involve the middle ear. This report defines the glomus tumor and discusses the symptomatology of the tumor with respect to the various developmental courses it may follow. Forty clinical cases of glomus tumor are reviewed, with emphasis upon the incidence of the tumor and its symptoms, including the audiological manifestations noted in this series of cases. Current medical management of the glomus tumor recommends surgical removal of the lesion when possible; however, irradiation and embolization of the tumor may also be considered when its invasion into surrounding structures has been extensive. The pathology and its treatment may have marked temporary or permanent effects upon the hearing of the patient, and the importance of ongoing audiological management is therefore emphasized.
