Comparative results with different cochlear implants.

The cochlear implant program in Budapest began in 1985, since when 60 operations have been performed, 14 of them on children (51 primary procedures and 9 reimplantations). Different devices and also different techniques have been used: extracochlear promontory, extracochlear round window and intracochlear implants. Various speech processors were applied; at first a digital pulsatile sound-encoding system, later on analog processors were used, while processors operating on the basis of the CIS strategy are preferred nowadays. The operations were performed on both pre- and postlingual patients. In several cases contralateral hearing improvement was observed 6 months after the operation. Considerable experience has been gained of unique cases, such as a deaf-blind prelingual child and prelingual twins. Evaluating cochlear implant performance, in addition to the usual audiological tests measuring postoperative speech understanding, warble tone sound field thresholds were also established.

[Cochlear implants].

Cochlear implantation is a method of utmost importance recently employed in ear surgery. It makes even speech understanding possible with electrical stimulation of the inner ear in case of bilateral total deafness of cochlear origin. The authors have performed cochlear implantation for 10 years at the Ear-Nose and Throat Clinic of Semmelweis University. Since 1985 different implantation techniques have been used in case of 58 patients, both adults and children. The authors give account of of technical details, rapidly changing selection criteria and the call attention to the problems of peri- and postoperative period and rehabilitation, on they basis of their own results. Importance of team-work of the ear-surgeon, audiologist, psychologist, physicist and speech-therapist is emphasized, because success of the operation is based on proper selection, skillful operating techniques and postoperative rehabilitation, as well.

Cochlear implants in children.

The authors give an account of their experiences with cochlear implants on the basis of 10 years' work. Preoperative evaluation, operating methods and postoperative rehabilitation are presented. During a decade 56 operations were performed, 11 of them on children. Results with prelingually deaf children are demonstrated together with the phenomenon of hearing improvement observed on the contralateral side of the operation.

Auditory brainstem potentials in uraemia.

Evoked response audiometry was carried out to assess the viability of the auditory pathway in haemodialysed patients. The latency of the waves III and V and I-V interpeak latencies were significantly longer in the renal patients compared to the control group. The I-V interpeak latency was longer in 8 of our 13 patients than the upper limit (4.38 ms) in our laboratory. The possible cause for the central auditory dysfunction may be multifactorial, including the effect of metastatic calcifications, repeated occurrence of disequilibrium syndrome, or some small, molecular, toxic, metabolic substance. The significance of the different factors may vary among different haemodialysis centres.

Diagnosis of hearing impairment in childhood.

The authors carried out BERA examinations in 46 children difficult to test. Seven cases are described in detail. In connection with these cases attention is drawn to the unforeseeable difficulties of this examination method used already widely.
