Abstract
OBJECTIVE: This study aimed to investigate the risk factors for postoperative arytenoid dislocation caused by endotracheal intubation.
METHODS: From September 2014 to September 2016, the records of 28 patients with a history of postoperative arytenoid dislocation were reviewed. Patients matched in type of anesthesia and surgery were chosen as the control (n = 56). Recorded data for all patients were demographics, smoking status, alcoholic status, operation time, and anesthesia procedures. For arytenoid dislocation cases, we further analyzed the incidences of the left and right arytenoid dislocations. Categorical variables were presented as frequencies and percentages, and were compared using the chi-square test. Continuous variables were expressed as means ± standard deviation and compared using the Student unpaired t test. To determine the predictors of arytenoid dislocation, a logistic regression model was used for multivariate analysis. Statistical significance was indicated by P < 0.05.
RESULTS: Twenty-eight patients demonstrating postoperative arytenoid dislocation (10 women and 18 men) were included, with a mean age of 55 ± 12 years. Sixteen patients (57.14%) had left arytenoid dislocation and 12 (42.86%) had right arytenoid dislocation. Univariate analysis indicated that body mass index (BMI) was associated with arytenoid dislocation (P < 0.01), and logistic regression analysis showed that BMI (P = 0.025) was an independent risk factor for postoperative arytenoid dislocation.
CONCLUSIONS: BMI might be the independent risk factor for postoperative arytenoid dislocation.
