Improvements in spatial hearing were also observed. No differences were found between children and adults in all tests in this study.Ĭonclusions: Cochlear implantation in post-lingually deaf adults and children with SSD can achieve a speech perception outcome comparable with CI in conventional candidates. No adverse events were reported during the study period. In the SSQ questionnaire, the post-operative results showed a beneficial effect of the CI. With respect to the Speech Test in quiet conditions: Word recognition in noise improved from 5.7% preoperatively to 71.8% at a mean follow-up of 1 year. Positive results in the Auditory Lateralization Test were found. For adults, the most common etiology was idiopathic sudden sensorineural hearing loss (SNHL). With respect to the SSQ questionnaire, parents were more satisfied within the postoperative period than within the preoperative period. The processor was used for >12 h in all cases. In the Speech Test, word recognition in noise improved from 2% preoperatively to 61.1% at a mean follow-up of 1 year (S0 condition) in children. They showed positive results in the Auditory Lateralization Test. Results: In children, the most common etiology was idiopathic sensory-neural hearing loss. All results were obtained after 12 months of CI activation. The Speech, Spatial, and Qualities of Hearing Scale (SSQ) questionnaire was also used. In all cases we evaluate: Speech perception thresholds disyllabic words test (65 dB SPL) were performed in the modalities S0–SCI–SNH and Auditory Lateralization Test. Patients and Method: Twenty-three children and twenty-one adult patients that were candidates for CI with single-side deafness were included. Objective: To determine audiological and clinical results of cochlear implantation (CI) comparing two populations with single-sided deafness (SSD): post-lingually deaf children between 6 and 12 years of age, and post-lingually deaf adults, in order to evaluate the effect of CI in different age groups. 3Hearing and Balance Laboratory, Las Palmas de Gran Canaria University Institute of Intelligent System and Numeric Application in Engineering, Las Palmas, Spain.2Department of Otolaryngology, Head and Neck Surgery, Complejo Hospitalario Universitario Insular Materno Infantil de Gran Canaria, Las Palmas, Spain.1Department of Clinical Sciences, University of Las Palmas de Gran Canaria, Las Palmas, Spain.Nadia Falcón Benítez 1, Juan Carlos Falcón González 2, Ángel Ramos Macías 2 *, Silvia Borkoski Barreiro 2 and Ángel Ramos de Miguel 3
