After ENT cancer surgery, postoperative respiratory complications are common, especially after tracheostomy.~Problems with lung ventilation called atelectasis are largely associated with these complications. These atelectasis develop within minutes of the start of general anesthesia. Patients who develop a complication require longer postoperative oxygen treatment and more physical therapy.~The diagnosis of atelectasis can be made by standard chest radiography, which is a source of radiation and requires moving the patient. An alternative technique, lung ultrasound, is a non-irradiating examination that can be performed in the patient's bed. It is routinely performed in the postoperative surveillance room and in the intermediate care unit at the Centre Léon Bérard.~The objective of this study is to characterize the pulmonary status of patients after ENT cancer surgery.~We wish to collect and analyze the pulmonary abnormalities revealed by the ultrasound scans performed in the post-anesthesia care unit (PACU), at day 1 and at day 2 after ENT cancer surgery with tracheostomy.
