Assessment of Facial Measurements, the Length of Mouth Corner-mandible Angle and Incisors-mandible Angle, for Determining the Proper Sizes of Oropharyngeal Airway

Not Applicable

Completed

• Conditions: General Anesthesia
• Interventions: Device: the length between incisor and mandible angle; Device: the length between mouth corner-mandible angle

• Registration Number: NCT01945411
• Lead Sponsor: Yonsei University

Brief Summary

The purpose of this study is to assess the facial measurements for determining the proper sizes of oropharyngeal airway. Investigators hypothesized that the length between incisors and mandible angle is more appropriate to estimate the size of oropharyngeal airway compared with the length between mouth corner and mandible angle.

Active comparator	the length between mouth corner-mandible angle	the length between mouth corner-mandible angle

Primary Outcome Measures

Name	Time	Method
proper size of oropharyngeal airway	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 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.
