Abstract [en]

Objective: To study the development of the bilateral benefit in children using bilateral cochlear implants by measurements of speech recognition and sound localization. Design: Bilateral and unilateral speech recognition in quiet, in multi-source noise, and horizontal sound localization was measured at three occasions during a two-year period, without controlling for age or implant experience. Longitudinal and cross-sectional analyses were performed. Results were compared to cross-sectional data from children with normal hearing. Study sample: Seventy-eight children aged 5.1-11.9 years, with a mean bilateral cochlear implant experience of 3.3 years and a mean age of 7.8 years, at inclusion in the study. Thirty children with normal hearing aged 4.8-9.0 years provided normative data. Results: For children with cochlear implants, bilateral and unilateral speech recognition in quiet was comparable whereas a bilateral benefit for speech recognition in noise and sound localization was found at all three test occasions. Absolute performance was lower than in children with normal hearing. Early bilateral implantation facilitated sound localization. Conclusions: A bilateral benefit for speech recognition in noise and sound localization continues to exist over time for children with bilateral cochlear implants, but no relative improvement is found after three years of bilateral cochlear implant experience.

Abstract [en]

Objective: To compare bilateral and unilateral speech recognition in quiet and in multi-source noise, and horizontal sound localization of low and high frequency sounds in children with bilateral cochlear implants. Design: Bilateral performance was compared to performance of the implanted side with the best monaural speech recognition in quiet result. Parental reports were collected in a questionnaire. Results from the CI children were compared to binaural and monaural performance of normal-hearing peers. Study sample: Sixty-four children aged 5.1-11.9 years who were daily users of bilateral cochlear implants. Thirty normal-hearing children aged 4.8-9.0 years were recruited as controls. Results and Conclusions : Group data showed a statistically significant bilateral speech recognition and sound localization benefit, both behaviorally and in parental reports. The bilateral speech recognition benefit was smaller in quiet than in noise. The majority of subjects localized high and low frequency sounds significantly better than chance using bilateral implants, while localization accuracy was close to chance using unilateral implants. Binaural normal-hearing performance was better than bilateral performance in implanted children across tests, while bilaterally implanted children showed better localization than normal-hearing children under acute monaural conditions.

Abstract [en]

This study analyses results from the first Swedish UNHS program. It includes over 33 000 measurement files from 14 287 children at two maternity wards. The screening program uses a two-stage TEOAE test procedure. A database was created in MedLog after data transformation in Word and Excel. The coverage rate was 99.1%. Bilateral pass rate after retesting was 97.0%. A unilateral pass criterion would have resulted in 1268 fewer children (9.0% of target group) for retesting and 231 fewer children (1.6% of target group) for diagnostic evaluation. When the first test was performed on the day the child was born, the pass rate was 64.8%, the pass rate increased to 89.2% when testing≥3 days after birth. High coverage rates and pass rates were found to be possible, independent of the number of children born at the maternity ward. Learning curves were observed in the program with improvements distributed over time. Test performance was clearly better when the children were tested day two after birth or later. © 2007 British Society of Audiology, International Society of Audiology, and Nordic Audiological Society.

Abstract [en]

This review discusses the need for universal neonatal hearing screening. Historical background is given concerning conventional childhood hearing screening programmes in western countries. Direct studies on the effects of very early habilitation programmes on speech and language development are cited. Measurement of otoacoustic emissions (OAE) as a tool for neonatal hearing screening is presented. The state of neonatal hearing screening programmes in the US and in Europe, particularly in Sweden, is discussed.

Abstract [en]

The purpose of the present investigation is to describe how parents experience a delayed identification of their child's hearing impairment. Ten parents of 8 children were interviewed. The impairment was confirmed when the children were between 2 years, and 5 years and 8 months. The results show that the parents and their child pass through a series of distinct phases: Unawareness, Suspicion, Confirmation and Habilitation. After the birth of the child there was first a calm period, which lasted until the possibility of a hearing impairment was suspected. Once the suspicion was raised, a time of much anxiety and frustration ensued. The parents described how defective communication and misunderstanding lead to frequent conflicts with their child. The differing behaviour of the child, in combination with poor language development, initiated referral to audiological assessment and confirmation of the hearing impairment. After confirmation, the parents felt relief but at the same time a sorrow. When hearing aids had been fitted and education in sign language was under way, the child's language and social behaviour improved. Supposedly, the late detection is explained by the combination of an insufficient test method that cannot detect all children with a hearing impairment and, in cases of uncertainty, a tendency to let the child pass rather than 'bringing bad news'. All parents in the present study would have wished to participate in a hearing screening program for new-borns, had the opportunity been present.
