Several tests have been proposed to predict difficult laryngoscopy or intubation. The thyromental distance (TMD) is often used for these purposes but this measurement, used alone, is unreliable. This study tested the hypothesis that the ratio of the patient's height to TMD (ratio of height to TMD = RHTMD) would improve the accuracy of predicting difficult laryngoscopy compared with TMD alone. Two hundred and seventy patients were evaluated preoperatively using the TMD and RHTMD. The two tests… CONTINUE READING
