Endotracheal tube is a commonly used for general anesthesia in head and neck surgery. It is necessary to place the endotracheal tube in the trachea of the patient and then inflate the cuff with air. This is because the air-inflated cuff contacts the inner wall of the patient's trachea to deliver oxygen through the tube. If the cuff does not inflate, oxygen will leak through the space between the cuff and the patient's trachea. In addition, the risk of pneumonia increases. Therefore, after placing the endotracheal tube in the patient's trachea, the cuff is immediately inflated with air. However, when the cuff is inflated using an excess of air, the cuff may pressurize the mucous membrane of the tracheal wall and cause ischemia. Pressure in the over-inflated cuff was also found to be associated with post-operative sore throat, vocal cord paralysis, and nerve damage. Therefore, appropriate amount of air should be used to inflate the cuff into the air and adjust the pressure within the cuff to be within the range of 20-30 cmH2O. The authors thought that the pressure in the cuff could be changed during the operation due to various factors and that the pressure in the cuff should be monitored continuously. In this study, the investigators will monitor the cuff pressure during anesthesia and analyze the factors affecting the cuff pressure.

Adults who require endotracheal intubation for head and neck surgery under general anesthesia
Exclusion Criteria:
Adults who require endotracheal intubation for head and neck surgery under general anesthesia
Other: monitoring of the endotracheal tube cuff
We will enroll adult patients who will undergo endotracheal intubation for general anesthesia of head and neck surgery. The cuff pressure of the endotracheal tube will be monitored continuously during anesthesia. The cuff pressure value will be recorded and analyzed after completing the study.
Changes of cuff pressure during anesthesia
The investigators will monitor the pressure of the endotracheal tube cuff during anesthesia. The changes of the cuff pressure from the baseline value will be monitored continuously.
Time frame: participants will followed until post-operative 1 day.
