Primary Outcome Measures

Name	Time	Method
the proportion of patients whose oropharyngeal airway is proper	up to 10 minutes after the start of anesthetic induction	The oropharyngeal airway will be inserted into the patient's mouth. Investigators will check the laryngeal view using fiberoptic bronchoscope and the adequacy of ventilation after the investigator ventilates the patient using the face mask. If both the laryngeal view and ventilation are appropriate, the size of oropharyngeal airway will be considered as the proper size for the patient.
