UNLABELLED: Cochlear implantation of congenitally deaf children with inner ear malformations is gaining special interest. Although the number of the reported cases is increasing, the decision for implantation needs thorough investigation. Preoperative evaluation, surgical approach and postoperative follow-up can be challenging. STUDY DESIGN: A retrospective analysis of two cases with inner ear malformations. PATIENTS: One patient was a 3-year-old-girl who had cochlear and cochleovestibular nerve aplasia on the left side and incomplete partition on the other side. The other patient was a 5-year-old-boy who had hypoplastic cochlea on both sides. Both of them also had vestibular anomalies. Cases were implanted by using multichannel cochlear implant. RESULTS: No complications were encountered. Both patients responded to acoustic stimuli, and their speech perception skills were improved. After 10 months of cochlear implant use, their results seem encouraging. CONCLUSION: Except cochlear or cochleovestibular nerve agenesis, inner ear malformations cannot be accepted as a contraindication for cochlear implantation. Although there can be difficulties during the surgery or in the postoperative period, patients with inner ear malformations can also benefit from cochlear implantation. It is essential that all possible complications and postoperative performance should be discussed with the parents.
OBJECTIVE: The aim of the study was to assess the speech development of children with at least 2 years' hearing experience with a cochlear implant (CI). METHODS: One hundred and six children were tested, all of whom had used the CI for at least 2 years. Receptive and expressive language development were tested using the scales of early communication skills for hearing-impaired children after Geers and Moog and the Reynell developmental language scales III. In addition, free-field audiometry was performed. Pre-postoperative measurements were compared statistically, and a linear regression analysis was carried out. RESULTS: Clear improvements in the gain in functional hearing 2 years after receiving the CI as well as clear improvements in both speech perception and speech production were ascertained. All deviations were statistically highly significant (P<0.000). The receptive and expressive speech test results correlate positively to a great extent. The results of logistic regressive analysis indicate that the speech production measured depends decisively on age at implantation, age at time of test, speech production before implantation, and additional handicaps. CONCLUSION: Based on the conception of the WHO, a statistically significant improvement of both impairment and disability can be confirmed. In the present study, the regression analysis established the age at implantation as the most important prognostic factor. While the percentage of children with good speech development is larger with early implanted children than with late implanted children, some of the children among the early implanted group show unsatisfactory speech development of unknown origin. Improvements in speech development are likely to be achieved when more children are diagnosed and implanted early. This finding urgently requires the introduction of a general newborn screening program. Thorough anamnesis and assessment during parent counseling of the manifold factors described are a prerequisite for the precise estimation of the difficulties to be met and the expected effectiveness of the implant in each individual case.
The presence in childhood of tinnitus is still a neglected problem both in pediatric and otorhinolaryngological literature, even if it is not uncommon in the pediatric population. In fact its incidence ranges from 13 to 29% in children with normal hearing function and is reported in 59% of children with hearing loss. Even if a child does not mention the existence of tinnitus, nevertheless, it may cause difficulties in concentration and bring about behavioral problems such as irritation, nervousness and deterioration in the lingual capacity. It is recommended to perform standardized studies regarding pediatric tinnitus. First of all, an accurate medical history must be performed asking specifically about tinnitus. Then it is necessary to perform an audiological examination that includes the subjective description and the following audiometric tests, pure tone audiometry; tympanometry; and tinnitus measurements.
