OBJECTIVE: The aim of the present preliminary study was to assess whether the sternomental distance ratio (SMDR) could be suitable as a predictor of difficult laryngoscopy, in both normal surgical patients and patients scheduled to undergo thyroid tumor surgery. METHODS: Two hundred and twenty-one consecutive adult patients (among them 122 patients with presumed normal airways and 33 patients with thyroid tumors), scheduled to undergo elective surgery under general anesthesia, were included in this study. Physical and airway characteristics, SMDR, difficult laryngoscopy (using Cormack-Lehane scale) and any kind of assisted intubation were assessed. RESULTS: Decreased SMDR demonstrated a strong correlation with difficult laryngoscopy in both thyroid tumor (Kendall's tau-b -0.578 (P=0.004) and normal patients -0.362 (P<0.001). Difficult laryngoscopy was 0 at SMDR>1.9 and 33% at SMDR <1.55 (P<0.001). The higher the SMDR was, the better the glottic view obtained. CONCLUSIONS: ? SMDR>1.9 indicates an easy laryngoscopy, whereas SMDR <1.55 indicates a difficult one in both thyroid tumor and normal patients. SMDR is an objective test to assess difficult airway in thyroid surgery. Copyright © 2020 by Academy of Sciences and Arts of Bosnia and Herzegovina.
