Frequently, this situation requires inclusion of segmental resection of the mandible into the surgical plan. This approach requires adequate reconstruction for preservation of satisfactory functional and esthetic treatment results. Selection of reconstruction method remains an important clinical problem in everyday practice of a head and neck cancer specialist.</p><p><bold>Aim.</bold> To analyze clinical materials on the use of reconstruction plates in oncological practice, evaluate esthetic and functional results of their use in patients who underwent single-stage reconstruction after segmental resection of the mandible.</p><p><bold>Materials and methods.</bold> The results of treatment of 103 patients after segmental resection of the mandible with defect reconstruction using only a reconstruction plate or a reconstruction plate with a distant or free flap who were treated at the Loginov Moscow Clinical Scientific Center and N.N. Blokhin Scientific Medical Research Center of Oncology between 1998 and 2019 were analyzed.</p><p><bold>Results.</bold> Complications at various times (between 2 months and 3 years) were observed in 15 (14.6 %) patients. The most frequent complications were plate cutting through the skin and mucosa (6 (5.8 %) cases) and osteomyelitis of fragments of the mandible (7 (6.7 %) cases). In 2 (1.9 %) cases, plate fracture was observed. It is necessary to note that during anti-inflammatory treatment in 4 (3.9 %) patients, osteomyelitis was managed while 11 (10.7 %) patients required removal of the reconstruction plate. Per the data analysis, in patents with surgical defect in the anterior area (defects ТТ, АТТ, САТ per the J.S. Brown classification, 2016) complications are significantly more common (in 11 (23.9 %) of 46 cases) than in patients with limited defects of the body and condyle (defects АТ, АС) (in 4 (7.0 %) of 57 cases). The rate of complications is also significantly affected by radiation dose.</p><p><bold>Conclusion.</bold> Therefore, use of a plate for reconstruction of mandible defect is aesthetically and functionally acceptable reconstruction technique. Severe complications leading to plate removal are rare and were observed in 11 (10.7 %) patients.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение</bold>. Плоскоклеточный рак слизистой оболочки полости рта при местно-распространенных опухолевых процессах поражает нижнюю челюсть в 13–38 % случаев. Зачастую в подобной ситуации требуется включение в план хирургического вмешательства ее сегментарной резекции. Данный подход предполагает проведение адекватного реконструктивного этапа с целью сохранения удовлетворительных функциональных и косметических результатов лечения. Выбор метода реконструкции остается актуальным клиническим вопросом в практике специалиста по опухолям головы и шеи.</p><p><bold>Цель</bold> исследования – проанализировать клинический материал по использованию реконструктивных пластин в онкологической практике, оценить эстетические и функциональные результаты применения этих пластин у пациентов, которым выполнялась одномоментная реконструкция после сегментарной резекции нижней челюсти.</p><p><bold>Материалы и методы.</bold> Проанализированы результаты лечения 103 пациентов после сегментарной резекции нижней челюсти с восстановлением дефекта с помощью только реконструктивной пластины или реконструктивной пластины с перемещенным или свободным лоскутом, получавших лечение в Московском клиническом научном центре им. А. С. Логинова и Научном медицинском исследовательском центре онкологии им. Н.Н. Блохина с 1998 по 2019 г.</p><p><bold>Результаты</bold>. Осложнения в различные сроки (от 2 мес до 3 лет) выявлены у 15 (14,6 %) пациентов. Наиболее часто диагностировались прорезывание пластины через кожу и слизистую оболочку (6 (5,8 %) случаев) и остеомиелит фрагментов нижней челюсти (7 (6,7 %) случаев). В 2 (1,9 %) случаях наблюдался перелом пластины. Необходимо отметить, что на фоне проведения противовоспалительного лечения у 4 (3,9 %) больных явления остеомиелита были купированы, в то время как 11 (10,7 %) пациентам потребовалось удаление реконструктивной пластины. По данным проведенного анализа у больных с хирургическим дефектом в подбородочном отделе (дефекты ТТ, АТТ, САТ по классификации J.S. Brown, 2016) осложнения встречаются значительно чаще (в 11 (23,9 %) из 46 случаев), чем при ограниченных дефектах тела и ветви (дефекты АТ, АС) (в 4 (7,0 %) из 57 случаев). Большое влияние на частоту развития осложнений также оказывает доза лучевой терапии.</p><p><bold>Заключение</bold>. Таким образом, применение реконструктивной пластины при восстановлении дефекта нижней челюсти является эстетически и функционально приемлемым методом реконструкции. Тяжелые осложнения, приводящие к удалению пластины, редки и отмечены у 11 (10,7 %) больных.</p></trans-abstract><kwd-group xml:lang="en"><kwd>mandible</kwd><kwd>cancer of the oral mucosa</kwd><kwd>reconstruction</kwd><kwd>reconstruction plate</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>нижняя челюсть</kwd><kwd>рак слизистой оболочки полости рта</kwd><kwd>реконструкция</kwd><kwd>реконструктивная пластина</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The work was performed without external funding.</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Werning J.W.
