Many surgical rehabilitation methods are often technically complex or require expensive consumables.</p> <p><bold>AIM:</bold> This study aimed to develop a technique for restoring the natural position of the globe in patients with posttraumatic orbital deformities using superelastic biocompatible nickel–titanium implants.</p> <p><bold>METHODS: </bold>A single-center, observational, longitudinal pilot study was conducted using a consecutive sample of 20 patients after traumatic injuries of the facial skeleton with isolated fractures of the inferior and medial orbital walls. In all cases, restoration of the orbital walls and the natural position of the globe was performed using thin-profile superelastic nickel–titanium implants. The study was prospective in nature; qualitative outcomes of restoration of the natural position of the globes were assessed. Follow-up and evaluation of rehabilitation quality were performed using instrumental methods according to the following diagnostic algorithm: ophthalmologic examination; assessment of endoprosthesis position performed intraoperatively using a C-arm and at all stages of rehabilitation using computed tomography; evaluation of reparative processes in the implantation zone using Karl Storz 30° and 45° endoscopes on postoperative day 10. The study design included elements of experimental control, as the technique had not previously been applied in patients with orbital wall fractures. All patients were informed about the nature and technique of the surgery.</p> <p><bold>RESULTS: </bold>In all operated patients, the anatomical position and visual function of the globe were preserved or restored. The described method allows fabrication of an implant that maximally conforms to the reconstructed area, which reduces time and simplifies its placement, thereby decreasing the duration and improving the overall quality of the surgical procedure.</p> <p><bold>CONCLUSION: </bold>The method developed and presented in this study demonstrated high effectiveness and stability. In all operated patients, the anatomical position and visual function of the globe were preserved or restored.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование. </bold>Несмотря на развитие современных методик восстановительной хирургии, сохраняется ряд спорных вопросов, связанных с отсутствием единого подхода к лечению травматических переломов стенок орбиты, к применению того или иного способа её пластики. Многие методы хирургической реабилитации зачастую технически сложны или требуют наличия дорогостоящих расходных материалов.</p> <p><bold>Цель. </bold>Разработка методики восстановления естественного положения глазного яблока у пациентов с посттравматической деформацией глазницы с применением сверхэластичных биосовместимых имплантатов из никелида титана.</p> <p><bold>Методы. </bold>Проведено одноцентровое пилотное обсервационное продольное исследование с применением сплошной выборки из 20 пациентов после травматических повреждений лицевого скелета с изолированными переломами нижней и медиальной стенок глазницы. Во всех случаях восстановление стенок глазницы и естественного положения глазного яблока осуществлялось с применением тонкопрофильных сверхэластичных имплантатов из никелида титана. Исследование носило проспективный характер, оценивались качественные результаты восстановления естественного положения глазных яблок. Контроль результатов и исследование качества реабилитации проводились с использованием инструментальных методов по следующему диагностическому алгоритму: офтальмологическое обследование, оценка положения эндопротеза, проводившаяся интраоперационно с использованием С-дуги и на всех сроках реабилитации с применением компьютерной томографии, изучение репаративных процессов в зоне имплантации с применением эндоскопов Karl Storz 30<sup> </sup>и 45° на 10-е сутки после операции. Характер исследования включал элементы экспериментального контроля, так как методика ранее не применялась у пациентов с переломами стенок орбиты. Все пациенты были информированы о сути и методике хирургического вмешательства.</p> <p><bold>Результаты. </bold>У всех прооперированных пациентов удалось сохранить или восстановить положение и функцию глазного яблока как органа зрения. Указанный метод позволяет изготавливать имплантат, максимально соответствующий протезируемой зоне, что сокращает время и упрощает процесс его установки и тем самым сокращает время и повышает качество всего оперативного вмешательства.</p> <p><bold>Заключение. </bold>Разработанный и представленный в работе метод доказал высокую эффективность и стабильность. У всех прооперированных пациентов удалось сохранить или восстановить положение и функцию глазного яблока как органа зрения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>implants</kwd><kwd>nickel–titanium</kwd><kwd>orbital wall reconstruction</kwd><kwd>prosthetics</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>имплантаты</kwd><kwd>никелид титана</kwd><kwd>реконструкция стенок глазницы</kwd><kwd>протезирование</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Министерство образования и науки Российской Федерации</institution></institution-wrap><institution-wrap><institution xml:lang="en">Ministry of Education and Science of the Russian Federation</institution></institution-wrap></funding-source><award-id>FSWH-2020-0022</award-id></award-group><funding-statement xml:lang="en">The study was part of the state assignment of the Ministry of Science and Higher Education of the Russian Federation, Project No. FSWM-2025-0009</funding-statement><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания Минобрнауки России, проект № FSWM-2025-0009</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Shtin VI, Novikov VA, Balatskaya LN, Krasavina EA.
