The aim of this study was to compare the auditory outcome between two groups of patients with bilateral cochlear implantation depending on the time of placement of the second cochlear implant – less and more than one year after the first one. 14 patients with bilateral cochlear implantation were enrolled and they were divided into two groups depending on the time of placement of the second cochlear implant – less and more than one year after the first one. All participants have been evaluated with LiP test (Listening Progress Profile), MTP tests 3, 6, 12 (Monosyllabic-Trochee-Polysyllabic test), MSW test (Monosyllabic Word test), MSW-Phonemes test (Monosyllabic Word-Phonemes test), SLS test (Spoken Language Skill test), SLS-Words test (Spoken Language Skill-Words test), GASP test (Glendonald Auditory Screening Procedure). Follow-up period was at least 36 months. Mean score results of both groups were compared for the major EARS (Evaluation of Auditory Responses to Speech) battery tests. Statistical analysis demonstrated that children’s scores improved significantly over time in both groups. There was statistical significant difference between mean scores оf both groups only for the 1st month of MTP3 test (meangroupI=2,57; meangroupII=9,00; p=0,006). In all other tests (LiP, MTP6, MTP12, MSW, MSW-Phonemes, SLS, SLS-Words, GASP) we obtained comparable results in the observed groups. This is the first study that evaluates the auditory outcome after bilateral cochlear implantation in Bulgarian patients depending on the time between two operations – less and more than one year after the first one. The results have shown that both groups made progress and achieved substantial improvement, but we did not find any statistically significant difference in the auditory outcome between these two groups. Additional studies in larger group of patients with bilateral cochlear implants and long-term follow-up period would confirm оr rejected this.
