Endoscopic Resection of Sinus Osteoma

Surgery is often based on thin-slice CT planning, and intraoperative navigation and high-definition endoscopy can be used. The lesion is usually exposed through a nasal approach, and the osteoma is gradually abraded or chiseled away, protecting important structures such as the mucosa and orbital wall/skull base; sinus ostia are reconstructed and flushed if necessary. Hemostasis is performed after the operation, and packing or drainage is placed as appropriate. Postoperative monitoring includes bleeding, infection, and visual abnormalities, with the goal of relieving obstruction, improving ventilation, and alleviating symptoms. The above is general health information and not medical advice; specific information should be based on specialist evaluation and hospital protocols.
