Identification of middle ear dysfunction in young children: a comparison of tympanometric screening procedures.

Two acoustic immittance screening procedures were evaluated in conjunction with pneumatic otoscopy, performed by a pediatric otolaryngologist. The subjects were 204 3- and 4-yr-old children from a rural area in eastern North Carolina. Pass-fail criteria were examined using two middle ear screening procedures: (1) a "traditional" procedure based on measures of tympanometric peak pressure and acoustic reflexes, and (2) the tympanometric measures contained within the American Speech-Language-Hearing Association's (ASHA) revised Guidelines for Screening for Hearing Impairment and Middle Ear Disorders. The traditional procedure resulted in low specificity but high sensitivity, whereas ASHA's immittance procedure resulted in high specificity but only moderate sensitivity. The negative predictive value was very high for both procedures; however, positive predictive value was low, especially for the traditional procedure. Advantages and disadvantages of the two procedures and future research needs are discussed.

Application of an implantable bone conduction hearing device to patients with unilateral sensorineural hearing loss.

This investigation, comprised of five studies, was undertaken to determine if individuals with newly acquired profound unilateral hearing losses would benefit from an implantable bone-conduction hearing device. The bone conductor was implanted on the side of the deaf ear at the time of translabyrinthine acoustic tumor resection. Two areas greatly affected by unilateral hearing loss, speech recognition in noise and sound localization, were examined. No improvement in aided performance could be documented in either area.

A national survey of educational preparation programs for early intervention specialists.

To examine the status of preprofessional education in early intervention, we conducted a nationwide survey of college and university programs offering degrees in education of the deaf. Curriculum content and practicum experiences with infants and toddlers and their families were examined, as well as general comments and recommendations of program directors. Additional information was sought from programs offering specializations at the preschool level to determine whether they had CED affiliation, and if so, whether they were certified in the areas of parent-infant education or early childhood education. The findings are discussed in the context of Public Law 99-457 and the growing emphasis on family centered early intervention.

Family-centered early intervention. The perceptions of professionals.

This paper, based on a nationwide survey, examines the attitudes and opinions of professionals regarding parent-professional involvement in the planning and implementation of goals and services for hearing-impaired infants and toddlers and their families. The implications of the findings are discussed as they pertain to PL 99-457, the new federal mandate for services to young children with special needs and their families.

Implantable bone-conduction hearing device: practical considerations.

An implantable bone conduction hearing device can be of significant benefit to carefully selected patients with noncorrectable conductive hearing losses. However, for some patients the device has significant limitations. This paper presents several practical issues that need to be considered before a decision is made regarding implant surgery. It is recommended that, whenever possible, air conduction hearing aids remain the first option considered when a patient's conductive hearing loss cannot be resolved through traditional medical management.

Clinical application of an implantable bone conduction hearing device.

For some patients, the transcutaneous bone-conduction implant offers a viable alternative to conventional amplification. However, this option should be employed only after considering the relative advantages and disadvantages of conventional medical management and, when feasible, the fitting of air-conduction amplification. The cases presented here illustrate some important factors to consider in the selection and fitting of bone-implant candidates.

A new challenge for pediatric audiology: Public Law 99-457.

When fully implemented, the most recent amendments to the Education of the Handicapped Act will have a substantial impact on expanding services to infants and toddlers with handicapping conditions and their families. Audiologists in many settings will be called upon to participate in the implementation of this new mandate. It is imperative that audiologists be well informed about Public Law 99-457 as state and local policies are being developed and implemented. This article reviews the new law with emphasis on its implications for young hearing-impaired children, their families, and the audiologists who serve them.

Pure-tone and acoustic immittance screening of preschool-aged children: an examination of referral criteria.

Seventy-five 3- and 4-yr-old children participated in a hearing screening program that included both pure-tone and acoustic immittance measures. ASHA's guidelines for acoustic immittance screening were modified to include a rescreening of all children failing the immittance test. Results were then compared to those projected from the existing ASHA criteria and two other screening protocols. Our findings revealed a higher incidence of otologic abnormalities in preschoolers compared to school-aged children and a higher incidence of false positives, even when immittance rescreening was provided. Pure-tone audiometry was ineffective as a means of identifying otologic abnormalities. A comparison of the immittance screening protocols indicated that the ASHA guidelines are likely to result in an excessive number of false-positive medical referrals. Recommendations are made for procedural modifications aimed at improving the efficiency of this procedure.
