【 摘 要 】
Objective: This study was designed to evaluate the diagnostic performance of STOPBANG score and mandibulohyoid distance (MHD) towards difficult laryngoscopy among obstructive sleep apnea patients.Cross-Sectional StudyMethodology: Forty-one patients who had STOP-BANG scores of >3 and required tracheal intubation for general anesthesia were recruited in this cross-sectional study. MHD was measured through lateral cephalometry. After induction of anesthesia, an anesthesiologist who was blinded to the patient’s profile performed a laryngoscopy and evaluated the Cormack-Lehane grading. Sensitivity, specificity, positive and negative predictive values were determined for STOP-BANG and MHD. Binary logistic regression, receiver operating characteristics (ROC) and correlation analyses were employed. Results: Body mass index, neck circumference, and Mallampati scores were higher in the difficult laryngoscopy group. MHD was longer in difficult laryngoscopy group (25.40 ± 5.67 mm) than easy laryngoscopy group (20.17 ± 4.28 mm; p = 0.002). STOPBANG score was higher in difficult laryngoscopy group (5.86 ± 0.96 vs. 4.30 ± 0.98; p < 0.001). The combination of MHD and STOP-BANG score improved the quality of diagnostic test in predicting the laryngoscopy status with area under ROC of 87.6%, compared to each isolated parameter (i.e., MHD = 75.7%, STOP-BANG = 85.5%). Both MHD and STOP-BANG scores were significantly positive correlated (r = 0.42, p = 0.006).Conclusions: STOP-BANG score and MHD were useful in predicting difficult intubation. The diagnostic performance improved further when combining both parameters.
