The study evaluated a clinical sign to predict the difficulty of tracheal intubation, focusing on the visibility of the faucial pillars, soft palate, and base of the uvula. A grading system was designed based on preoperative visualization of these structures, which was found to be a significant predictor of the difficulty in direct laryngoscopy (p < 0.001). The study included 210 adult surgical patients, and the results showed that if all three pharyngeal structures were visible, laryngoscopic visualization was relatively easy. However, if the faucial pillars and uvula were masked by the base of the tongue, laryngoscopy was more likely to be difficult. The study concluded that this clinical sign is a useful tool for predicting the ease or difficulty of orotracheal intubation in clinical practice.The study evaluated a clinical sign to predict the difficulty of tracheal intubation, focusing on the visibility of the faucial pillars, soft palate, and base of the uvula.
