С.М. Кирова в период с 2007 по 2018 г. Оценивали влияние размеров и локализации опухоли, клинических проявлений, вида доступа в полость IV желудочка на функциональные исходы лечения. Осложнения, связанные с доступом, оценивали по клиническим данным и по диффузионно-взвешенным изображениям, полученным при магнитно-резонансной томографии. С помощью метода логистической регрессии и ROC-анализа выявляли предикторы усугубления бульбарного синдрома и нарушений координации в послеоперационном периоде.</p></sec><sec><title>Результаты</title><p>Результаты. Определены основные преимущества малоинвазивного срединного доступа по сравнению с теловелярным: меньшая частота резекции задней полудуги позвонка С , отсутствие необходимости длительной постоянной ретракции мозжечка, сокращение длительности операции и снижение частоты ишемических изменений, обусловленных доступом. Доступы не различались по таким показателям, как локализация опухоли, необходимость предварительной установки наружного вентрикулярного дренажа, радикальность удаления и частота послеоперационных осложнений. Однако размеры образований, удаленных через теловелярный доступ, были достоверно выше. Размер образования ≥37,5 мм – прогностически значимый фактор появления дисфагии после операции (чувствительность 86 %, специфичность 84 %).</p></sec><sec><title>Заключение</title><p>Заключение. Доступ через срединную апертуру является разумной альтернативой теловелярному доступу при удалении опухолей IV желудочка небольших размеров (&lt;30 мм) с каудальной или срединной локализацией. Применение срединного доступа уменьшает травматичность операции, снижает вероятность послеоперационных осложнений. При размере образования ≥37,5 мм в послеоперационном периоде следует ожидать нарастания выраженности бульбарного синдрома.</p></sec></abstract><trans-abstract xml:lang="en"><p>The study objective is to compare the efficacy and safety of the fourth ventricle tumor removal using median (through the median aperture) or telovelar approach.</p><sec><title>Materials and methods</title><p>Materials and methods. The analysis included 41 patients with space-occupying lesion of the fourth ventricle operated in the Neurosurgery Clinic of S.M. Kirov Military Medical Academy in 2007–2018. The anatomical characteristics (size and extension) and manifestations of the fourth ventricle tumors, as well as surgical factors (surgical approach to the fourth ventricle) which affect the functional outcome of the treatment were estimated. Complications associated with the approach were assessed clinically using diffusion-weighted magnetic resonance imaging. Logistic regression and ROC analysis were used to analyze the anatomical factors and extent of resection as predictors that affect the worsening of gait disturbance, speech/swallowing deficits in the postoperative period.</p></sec><sec><title>Results</title><p>Results. The analysis revealed main advantages of the median approach in comparison to the telovelar approach: a lower frequency of C laminectomy; no need for prolonged constant tonsillar retraction; a shorter surgery duration and lower number of ischemic changes in the surgical area, caused by approach. Meanwhile the telovelar approach was used to remove lesions bigger in size. Other factors, such as tumor extension, the need to preliminary insertion of an external ventricular drain, the frequency of postoperative complications, the extent of resection and the functional outcomes did not differ significantly between the approaches. Lesion size ≥37.5 mm is a significant prognostic factor for speech/swallowing deficits after the surgery with sensitivity of 86 % and specificity of 84 %.</p></sec><sec><title>Conclusion</title><p>Conclusion. Median aperture approach is a reasonable alternative to telovelar or transvermian approaches in the surgery of small fourth ventricle tumors (&lt;30 mm). The median approach allows to reduce the surgical injury rate and the likelihood of postoperative complications. If a lesion has a size ≥37.5 mm, an increase speech/swallowing deficits should be expected.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>опухоль</kwd><kwd>IV желудочек</kwd><kwd>теловелярный доступ</kwd><kwd>срединная апертура</kwd><kwd>хирургическое лечение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>tumor</kwd><kwd>fourth ventricle</kwd><kwd>telovelar approach</kwd><kwd>median aperture</kwd><kwd>surgical treatment</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Rajesh B.J., Rao B.R., Menon G. et al.
