In the course of the analysis of available foreign and domestic literature, 65 observations of trigeminal tumors with extracranial growth were found, the total removal of which was performed only in 20% of patients.</p> <p><bold>The aim of the study</bold> is to show the potential of skull base tumor surgery using an example of a successful surgical treatment of a patient with a spread trigeminal neurinoma located in the posterior, middle and infratemporal fossae, as well as to analyze the international scientific experience on this issue.</p> <p><bold>Clinical case description</bold>. A 60-year-old patient with a spread trigeminal neurinoma on the left was admitted to the Federal Scientific-Clinical Center of FMBA of Russia in February 2020. After an additional examination and preoperative preparation, a planned operation was performed — osteoplastic orbitozygomatic craniotomy, a microsurgical removal of the tumor through the subtemporal transcavernous approach. A good postoperative clinical result was obtained. An analysis of the available scientific literature on this problem has been performed. In the postoperative period, pain and neurological symptoms, hemifacial spasm completely regressed. 1.5 months after the operation, the tumor was shown to be totally removed by the control images.</p> <p><bold>Conclusion</bold>. Despite the extreme complexity of the pathology, the operation via the orbitozygomatic subtemporal transcavernous approach allows one to completely remove common and giant trigeminal neurinomas with a good functional result.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование</bold>. В ходе проведенного анализа доступной зарубежной и отечественной литературы найдено 65 наблюдений опухолей тройничного нерва с экстракраниальным ростом, тотальное удаление которых выполнено только в 20% случаев.</p> <p><bold>Цель</bold> — показать возможности методов хирургии опухолей основания черепа на примере успешного хирургического лечения пациента с распространенной невриномой тройничного нерва, локализованной в задней, средней и подвисочной ямках, а также проанализировать международный научный опыт по этому вопросу.</p> <p><bold>Описание клинического случая</bold>. В Федеральный научно-клинический центр ФМБА России в феврале 2020 г. поступил пациент в возрасте 60 лет с распространенной невриномой тройничного нерва слева. После дообследования и предоперационной подготовки выполнена плановая операция — костно-пластическая орбитозигоматическая трепанация черепа, микрохирургическое удаление опухоли с использованием субтемпорального транскавернозного доступа. Получен хороший послеоперационный клинический результат. Проведен анализ доступной научной литературы по этой проблеме. В послеоперационном периоде полностью регрессировали болевая и неврологическая симптоматика, гемифациальный спазм. Через 1,5 мес после операции на контрольных снимках опухоль удалена тотально.</p> <p><bold>Заключение</bold>. Несмотря на крайнюю сложность патологии, выполнение операции орбитозигоматическим субтемпоральным транскавернозным доступом позволяет тотально удалить распространенные и гигантские невриномы тройничного нерва с хорошим функциональным результатом.</p></trans-abstract><kwd-group xml:lang="en"><kwd>trigeminal neurinoma</kwd><kwd>middle</kwd><kwd>posterior and infratemporal fossae</kwd><kwd>hemifacial spasm</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>невринома тройничного нерва</kwd><kwd>средняя</kwd><kwd>задняя и подвисочные ямки</kwd><kwd>гемифациальный спазм</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Konovalov AN, Spallone A, Mukhamedjanov DJ, Tcherekajev VA.
