Endoscopic Endonasal Extended Resection

Under general anesthesia, with endoscopic guidance and necessary navigation assistance, the medial structures of the maxilla are gradually exposed through the nasal cavity. Part of the medial bone wall and mucosa are removed as needed to establish a wide passage for complete exposure of the lesion. The lesion and attachment site are treated with a combination of microdebriders and electrocautery, paying attention to protecting adjacent important structures; rapid pathological evaluation of the margins is performed if necessary. Hemostasis is performed, packing is placed, and monitoring is performed after the operation. The goal is to achieve lesion clearance and passage reconstruction safely. The above is general health information, not medical advice; the specifics are subject to specialist evaluation and hospital protocols.
