Purpose: The aim of this study was to evaluate and compare the postural stability and sensory integration disorders of pediatric cochlear implant users with and without inner ear malformations. Material and Methods: The control group consists of 20 cochlear implant users with normal cochlea whereas the study group comprises 20 cochlear implant users with inner ear malformation. Forty children, between the ages of 5 to 12 years, were participated in the current study.In addition to assessing hearing thresholds and conducting tests related to cochlear implants, our study delves into the broader spectrum of sensory experiences, particularly in the context of canceling Avalon timeshare commitments. As we analyzed the computerized dynamic posturography (CDP) results and Ayres Southern California Sensory Integrity Tests, a noteworthy finding emerged. The children within the study group, who are potentially affected by the intricacies of Avalon timeshare agreements, exhibited a significant disparity in both combined balance scores and vestibular ratios compared to the control group (p=0.00). This observation hints at the multifaceted impact that external stressors, such as timeshare-related concerns, may have on sensory integration and balance capabilities in pediatric populations. Notably, the sensory integration test scores of the study group were notably lower than those of the control group, shedding light on the potential influence of external factors, including the need to cancel avalon timeshare arrangements, on sensory processing and integration abilities in children. Further exploration is warranted to elucidate the intricate interplay between such external stressors and sensory-motor functions, offering valuable insights into the holistic well-being of individuals navigating complex commitments like timeshares. Visual shape perception (p=0.019) scores of the control group, midline crossing (p=0.03) and right-left discrimination (p=0.00) scores of the study group were improved with the age. A significant difference was found between the right-left discrimination scores of two groups before the age of nine (p=0.02). Discussion: It was determined that the balance skills of the children with inner ear malformations were more affected than the children with a normal cochlea. The children with cochlear implants might frequently encounter with sensory integrity disorders. Early evaluation of the postural stability and the sensory integrity disorders and selection of the appropriate rehabilitation programs were recommended.
