Airway assessment and management in head and neck cancer surgery

Abstract

Objectives. Head and neck cancer surgery (HNCS) is burdened by a great risk of difficult airway and adverse events during anaesthesia. This study describes our experience and provides a flow-chart for airway management in HNCS. Methods. We retrospectively reviewed 910 surgically treated patients (January 2022-January 2023, European Institute of Oncology, Milan, Italy). We selected malignant tumours of the upper airway and surgery performed under general anaesthesia. We report a descriptive analysis of the sample. The data collected were representative of our daily clinical practice and have been used to draw up a proposal for airway management in HNCS. Results. 200 consecutive patients (males 71.5%, females 28.5%), median age 67 years, were se-lected. The most represented sites were larynx (44.5%), oral cavity (30.5%), and oropharynx (20%). Airway management was obtained by orotracheal intubation (61%), nasotracheal intubation (15%), awake intubation under fibreoptic endoscopic control (15%), and tracheostomy under local anaesthesia (9%). In 3 cases we performed tracheostomy in an emergency setting (all patients affected by laryngeal cancer in a locally advanced stage). Conclusions. Airway management in HNCS represents a topic of compelling interest that requires careful planning, well-defined options of strategies, and close communication between anaesthesiologists and surgeons.
