Endoscopic upper airway surgery involves accessing the larynx, trachea and upper aerodigestive tract via rigid or flexible endoscopy. These procedures are often performed for diagnostic or therapeutic management of airway pathology, including benign and malignant lesions. Anaesthetic management presents distinct challenges due to the shared airway, the need for optimal surgical access and the elevated risk of complications such as airway obstruction, inadequate lung ventilation and airway fire. A thorough preoperative assessment is essential, including evaluation of pathology characteristics, airway patency and patient co-morbidities. Anaesthetic planning must involve multidisciplinary collaboration. Oxygenation strategies include closed systems (e.g. conventional ventilation via microlaryngeal and laser-resistant tracheal tubes) and open systems (e.g. jet ventilation, spontaneous or apnoeic oxygenation with high-flow nasal oxygen). Each has specific indications, limitations and safety considerations. Tracheal extubation may carry significant risk and should follow a structured, risk-based approach. This article provides an in-depth overview of anaesthetic considerations, techniques and safety strategies for endoscopic upper airway surgery, highlighting the importance of planning, teamwork and adaptability in managing complex airway scenarios.
