During qualification, the following criteria were taken into account: audiometry results, use of the hearing aid in the non-implanted ear and benefit of the device, speech and hearing development after the first cochlear implantation.</p> <p><bold>Results.</bold> According to our findings the second cochlear implantation was recommended for 12 (24%) patients; in 16 (32%) cases the second cochlear implantation was refused; in 22 (44%) cases it was recommended to postpone implantation of the second device.</p> <p><bold>Conclusion. </bold>Our results demonstrate that the safe and effective way of qualifying for a second cochlear implant can restore binaural hearing that is crucial for the child's speech and hearing development and enhance integration into a world of peers.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель</bold> – разработать и систематизировать безопасные и эффективные критерии отбора кандидатов на установку второго импланта при проведении последовательной кохлеарной имплантации у детей.</p> <p><bold>Материал и методы.</bold> В исследовании приняли участие 50 детей после односторонней кохлеарной имплантации в возрасте от 2 до 12 лет. При отборе пациентов учитывались данные аудиологических исследований, тестирования речевого развития на основе слухового восприятия, данные о продолжительности и эффективности слухокоррекции уха, контралатерального оперированному.</p> <p><bold>Результаты. </bold>Двенадцати (24%) из 50 исследуемых детей рекомендовано выполнить вторую кохлеарную имплантацию, законным представителям шестнадцати детей (32%) отказано, принятие решения о билатеральном имплантировании двадцати двух детей (44%) было отложено.</p> <p><bold>Заключение.</bold> Изложенные нами принципы отбора пациентов на имплантацию второго уха позволяют повысить эффективность последовательной билатеральной кохлеарной имплантации через воссоздание у глухого ребенка бинаурального слуха, дающего дополнительные преимущества в становлении слухового восприятия, речи и интеграции в среду слышащих людей.</p></trans-abstract><kwd-group xml:lang="en"><kwd>sequential bilateral cochlear implantation</kwd><kwd>children</kwd><kwd>deafness</kwd><kwd>qualifications for bilateral implants</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>последовательная билатеральная кохлеарная имплантация</kwd><kwd>дети</kwd><kwd>глухота</kwd><kwd>критерии отбора</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Manual on audiology and amplification.
