Removal of such objects can be challenging due to their proximity to vital anatomical structures. In addition to classical approaches (alveolar or Caldwell–Luc techniques), minimally invasive alternatives exist, including endonasal endoscopic surgery. In some cases, the use of a magnet for extracting metallic foreign bodies can minimize surgical trauma and reduce the risk of complications.</p> <p>In the present case, a metallic foreign body was incidentally detected in the maxillary sinus during implant treatment planning. The patient was asymptomatic at the initial visit and had last seen a dentist approximately three months prior for tooth extraction. Cone-beam computed tomography revealed a hyperdense object in the left maxillary sinus, identified as a surgical bur, likely displaced into the sinus during a previous extraction. After comprehensive assessment of the foreign body’s location relative to maxillary anatomical landmarks, access was planned through the anterior wall of the maxillary sinus. The object was removed via the perforation using a magnet, and the wound was sutured. The postoperative course was uneventful.</p> <p>Although rare, metallic foreign bodies in the maxillary sinus should be considered in the patient’s history, and appropriate diagnostic evaluation is essential. This clinical case demonstrates a minimally invasive technique for removing a metallic foreign body using a magnet. The approach is technically simple, atraumatic, can be performed under local anesthesia, and does not require specialized equipment, including endoscopic instruments.</p></abstract><trans-abstract xml:lang="ru"><p>Проникновение инородных тел в верхнечелюстную пазуху — редкое, преимущественно (более 60%) ятрогенное осложнение стоматологических вмешательств. Удаление таких объектов затруднено ввиду их возможной близости к жизненно важным анатомическим структурам. Наряду с классическими подходами (альвеолярным и по методу Колдуэлла–Люка) существуют малоинвазивные альтернативы, в частности эндоназальная эндоскопическая хирургия. В отдельных случаях для удаления металлических инородных тел целесообразно использовать магнит, что позволяет минимизировать хирургическую травму и снизить вероятность осложнений.</p> <p>У пациента на этапе планирования имплантации в верхнечелюстной пазухе случайно диагностировано инородное металлическое тело. На первичном приёме пациент жалоб не предъявлял, стоматолога посещал около 3 мес назад по поводу удаления зубов. При проведении конусно-лучевой компьютерной томографии установлено, что гиперденсное образование в левой гайморовой пазухе — хирургическая фреза, которая могла попасть в верхнечелюстную пазуху в процессе удаления зуба. После комплексной оценки положения инородного тела по отношению к анатомическим ориентирам верхней челюсти было принято решение о доступе к нему через переднюю стенку верхнечелюстной пазухи. Через перфорационное отверстие инородное тело было удалено с использованием магнита. Рана ушита. Послеоперационный период протекал без особенностей.</p> <p>Металлическое инородное тело в верхнечелюстной пазухе — редкое, но возможное явление. Поэтому так важно учесть анамнестические данные и тщательно провести необходимые диагностические процедуры. Представленный клинический случай описывает малораспространённый способ удаления металлического инородного тела с использованием магнита. Данный подход отличается технической простотой, малой инвазивностью и атравматичностью. Процедура выполнима под местной анестезией и не требует применения специализированного оборудования, включая эндоскопическую технику.</p></trans-abstract><kwd-group xml:lang="en"><kwd>foreign body</kwd><kwd>maxillary sinus</kwd><kwd>surgical treatment</kwd><kwd>magnet</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>инородное тело</kwd><kwd>верхнечелюстная пазуха</kwd><kwd>хирургическое лечение</kwd><kwd>магнит</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Selvi F, Enoz M, Yazgin I, et al.
