Потеря слуха представляет собой наиболее распространенную форму сенсорной инвалидности среди детей по всему миру. Нормальный слух является важнейшим условием для полноценного социального и языкового развития детей, соответствующего их возрастным особенностям. Успешная слухоречевая реабилитация определяется как восстановление или приобретение слуха и речи пациентом. В качестве междисциплинарной задачи слухоречевая реабилитация детей, перенесших кохлеарную имплантацию, включает в себя ряд специфических аспектов.

Глубокое понимание этих аспектов не только повышает точность врачебных прогнозов, но и способствует выявлению факторов, подлежащих коррекции для достижения оптимальных результатов слухоречевой реабилитации в дальнейшем. Цель настоящего исследования заключается в анализе потенциальных факторов, которые могут оказывать влияние на результаты слухоречевой реабилитации детей, прошедших кохлеарную имплантацию.

Hearing loss is the most common form of sensory disability among children worldwide. Normal hearing is essential for the full social and linguistic development of children corresponding to their ageappropriate characteristics. Successful auditory and verbal rehabilitation is defined as the restoration or acquisition of hearing and speech by a patient. As an interdisciplinary task, auditory and verbal rehabilitation of children who have undergone cochlear implantation (CI) includes a number of specific aspects.

A thorough understanding of these aspects improves not only the accuracy of medical prognosis, but also helps to identify factors that need to be corrected to achieve optimal results of auditory and verbal rehabilitation in the future. The aim of this study is to analyze potential factors that may influence the results of auditory and verbal rehabilitation of children who have undergone CI.
