Objective:
Arytenoid dislocation (AD) is a rare laryngeal injury with diagnostic and therapeutic challenges. To identify preoperative prognostic factors for voice recovery after closed reduction and develop a simple risk scoring tool.
Methods:
This retrospective study included 128 patients with AD who underwent closed reduction. Outcomes were evaluated using Grade, Roughness, Breathiness, Asthenia, Strain (GRBAS) scale at 1 month. Logistic regression identified predictors; a scoring model was built and internally validated.
Results:
Delayed intervention and nonintubation-related etiology were independent predictors of poor outcomes. A three-factor scoring tool (age >58 years, intervention >29 days, nonintubation-related) showed good predictive ability (area under the receiver operating characteristic curve = 0.785; Hosmer-Lemeshow P = 0.60).
Conclusion:
This tool enables early risk stratification using routine clinical variables and may assist in the individualized management of AD.
Level Of Evidence:
Level 4.
