    AbstractPredicting and managing the difficult airway is a lifesaving and vital basic task for the anesthetist. Current guidelines of all important societies include thyromental distance (TMD, "Patil") as a possible predictor for a difficult airway and includes two important aspects for airway management: the mandibular space and the flexibility of the cervical spine. We evaluated knowledge and execution regarding TMD for predicting a difficult airway on participants at the Euroanaesthesia (ESA) congress and German Anaesthesia Congress (DAC) in 2014. Our evaluation consisted of a theoretical part with questions regarding general knowledge and a practical evaluation with anesthetists performing on a human airway model. Practical evaluations were performed separately from other participants. During the DAC 245 (ESA 230) physicians participated, of which 64% were male (ESA 58%). At the DAC 182 (74.3%) and ESA 82 (35.6%) participants knew about Patil/TMD. Its use as a predictive score for a difficult airway was known by 122 (49.8%; DAC) and 79 (34.4%; ESA) participants. The correct definition for intubation was given by 45 (25.7%) at the DAC and 56 (24.3%) at ESA. Only 40-41% of the participants measured the correct distance for TMD. Only 6.1-6.5% completed both the theoretical and practical parts correctly. As non-invasive TMD includes two different aspects of patient airways and is part of current guidelines, education and training must be extended to assure adequate evaluation in the future.
