Sinonasal papilloma is a benign tumor. The standard treatment for sinonasal inverted papilloma (SIP) is surgical intervention. The tumor is located primarily in the maxillary sinus (50.9 %). Sinonasal inverted papilloma originated from the maxillary sinus has aggressive characteristics and can dislodge local anatomical structures, infraorbital canal in particular.</p><p><bold>Aim</bold>. To present a descriptive characteristic of structural changes in the infraorbital canal during SIP growth and determine the optimal volume of canal dissection.</p><p><bold>Materials and methods</bold>. A retrospective study of patients with SIP was performed. From the total cohort (n = 37), 15 patients with primary localization of sinonasal inverted papilloma in the maxillary sinus were selected. In all cases, the same diagnostic algorithm was used. Separately, evaluation of infraorbital canal anatomy based on preoperative analysis of computed tomography of the paranasal sinuses and intraoperative endoscopic exam was performed. Surgical strategy used in all cases consisted of endoscopic SIP tissue removal, total resection of the mucoperiosteum and subperiosteal dissection of all walls of the maxillary sinus using a bur. During surgery material was collected for control histological examination.</p><p><bold>Results</bold>. In 20 % of cases, changes in the walls of the infraorbital canal in the form of hyperostosis, erosion and dehiscence were observed. In 13.3 % of cases, growth of sinonasal inverted papilloma caused distortions in the structure of infraorbital canal walls. In all cases, computed tomography data showed the same results as intraoperative endoscopic visualization. For removal of the lesion and pathologically changed walls of the infraorbital canal, transnasal endoscopic partial maxillectomies (type 3 or 4) were performed. Follow-up duration varied between 1 and 5 years, mean follow-up duration was 3 years. SIP resection was effective in all patients, no recurrences were observed.</p><p><bold>Conclusion</bold>. For SIPs growing in the maxillary sinus, condition of the infraorbital canal must be of special interest. The study showed the effectiveness and flexibility of the surgical strategy consisting of the combination of total mucoperiosteum resection with subperiosteal dissection of all walls of the maxillary sinus.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение</bold>. Синоназальная папиллома относится к группе доброкачественных новообразований. Стандартом лечения инвертированной синоназальной папилломы (ИСП) является хирургическое вмешательство. Новообразование преимущественно локализуется в верхнечелюстной пазухе (50,9 %). Инвертированная синоназальная папиллома, исходящая из верхнечелюстной пазухи, обладает агрессивными свойствами и может вызывать нарушения локальных анатомических структур, в частности – подглазничного канала.</p><p><bold>Цель исследования</bold> – дать описательную характеристику структурных изменений подглазничного канала на фоне роста ИСП и определить оптимальный объем диссекции канала.</p><p><bold>Материалы и методы.</bold> Проведено ретроспективное исследование пациентов с ИСП. Из общей когорты (n = 37) для анализа были отобраны 15 пациентов с первичной локализацией инвертированной синоназальной папилломы в верхнечелюстной пазухе. Во всех случаях соблюдался единый алгоритм диагностики. Отдельно оценивалась анатомия подглазничного канала на основании данных предоперационного анализа компьютерной томографии околоносовых пазух и интраоперационного эндоскопического осмотра. Хирургическая тактика, применяемая во всех случаях, заключалась в эндоскопическом удалении ткани ИСП, идентификации и резекции зоны/зон роста новообразования, тотальном удалении мукопериоста и субпериостальной диссекции бором всех стенок верхнечелюстной пазухи. В ходе операции проводился забор материала для контрольного гистологического исследования.</p><p><bold>Результаты</bold>. В 20 % случаев были обнаружены изменения стенок подглазничного канала в виде гиперостоза, эрозии и дегисценции. В 13,3 % случаев рост инвертированной синоназальной папилломы вызывал нарушения структуры стенок подглазничного канала. Во всех случаях данные компьютерной томографии совпали с результатами интраоперационной эндоскопической визуализации. Для удаления новообразования и патологически измененных стенок канала применялись трансназальные эндоскопические парциальные максиллэктомии 3-го или 4-го типов. Пациенты наблюдались в сроки от 1 года до 5 лет, средний период наблюдения составил 3 года. Резекция ИСП оказалась эффективной у всех пациентов, случаев рецидива отмечено не было.</p><p><bold>Заключение</bold>. При локализации зоны роста ИСП в верхнечелюстной пазухе особое внимание следует уделять состоянию подглазничного канала. В исследовании продемонстрированы эффективность и универсальность реализованной хирургической тактики, обусловленные сочетанием полного удаления мукопериоста с субпериостальной диссекцией бором всех стенок верхнечелюстной пазухи.</p></trans-abstract><kwd-group xml:lang="en"><kwd>sinonasal inverted papilloma</kwd><kwd>maxillary sinus</kwd><kwd>infraorbital canal</kwd><kwd>transnasal endoscopic partial maxillectomy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>инвертированная синоназальная папиллома</kwd><kwd>верхнечелюстная пазуха</kwd><kwd>подглазничный канал</kwd><kwd>трансназальная эндоскопическая парциальная максиллэктомия</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Rha M.S., Kim C.H., Yoon J.H., Cho H.J.
