This study looks to devise a scoring system that can be used to predict difficult front of neck access due to increased depth of cricothyroid membrane. This study will recruit elective patients undergoing operations for a variety of procedures and correlate their measured (by ultrasound) cricothyroid depth with other difficult airway predictors (such as Mallampatti score).
