The Role of Measuring Preoperative Social Maturation Score in Children With Additional Needs Who Underwent Cochlear Implantation

Background and Objectives: Additional needs refer to specific requirements or support for individuals with disabilities or syndromes. Intellectual ability is a crucial outcome determinant of a cochlear implant. The social quotient (SQ) is an indirect predictor of intellectual capacity and social skills. This study aimed to investigate the clinical significance of the SQ on children with additional needs who received cochlear implants. Subjects andMethods: This study included 24 patients with diagnosed developmental delays and syndromes, who demonstrated SQ scores of <70. Preoperative social skills were evaluated using the SQ. All patients underwent cochlear implantation (CI) surgery before 7 years of age. Outcomes were evaluated using the Infant-Toddler Meaningful Auditory Integration Scale (IT-MAIS) and Categories of Auditory Performance (CAP) scores. Data were collected through a retrospective chart review.Results: Children were categorized into three groups based on their SQ. There were no correlations between the preoperative SQ and IT-MAIS or CAP scores at 2 and 5 years of follow-up postoperatively. The CI outcomes of children with low SQ (<70) differed from those with normal development (SQ>70). In the low-SQ group, inner ear anomalies were observed in 10 (41.7%) patients. Although not statistically significant, these children exhibited a trend of lower average outcomes than children without inner ear anomalies.Conclusions: CI outcomes in children with additional needs positively affected auditory performance. Postoperative auditory and language skills tended to improve slowly in children with additional needs and a lower SQ. Over time, development gradually became more comparable to the other groups of children. However, this improvement was less than that observed in children without additional needs. Our findings support CI for children with additional needs as part of long-term auditory rehabilitation following surgery.
