Quantitative Compliance Based Classification of Submental Sign or Javid Sign

Prediction of difficult intubation is still a dilemma. Despite various predictors of difficult airway reported and discussed in the literature, no definite test exists to prevent mortality and morbidity related to difficult airway. Using a combination of different predictors of difficult intubation is logical to help minimizing this difficulty and establishing a safe anesthesia. Detection and presentation of any novel predictor can be helpful in achieving this goal. “Submental Sign” or “Javid Sign” a new predictor of difficult intubation, was reported by MJ Javid in 2011, but qualitative characteristic of this predictor was the most considerable drawback for using Submental Sign as an accurate predictor. The goal of this study is quantitative classification of Submental Sign or Javid classification to overcome false positive and false negative results of Submental Sign. In this article a novel scale is introduced for evaluating submental compressibility quantitatively.
