Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Could awake invasive airway assessment be more predictive for difficult airways in obese patients? The use of nasendoscopy assessment for the airway could be a useful additional invasive tool to predict the difficult airway in obese

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
It is less clear whether obesity increases the risk of difficult laryngoscopy or intubation. Some studies suggest that obesity is a risk factor for both difficult mask ventilation and difficult laryngoscopy, while other studies suggest that with proper positioning and preparation, ventilation and laryngoscopy are not difficult \[12,13\]. Wilson's score is an important development in predictivity of airway difficulties, Wilson's in his study (1988) attempted to deductively identify patients for whom intubation will be difficult.
This study aims to demonstrate the use of preoperative awake fibreoptic examination
