Predicting voice recovery after arytenoid dislocation (AD) is crucial. A simple risk score using age, intervention time, and cause can help stratify patients for better management of this rare laryngeal injury.
Area of Science:
- Otolaryngology
- Laryngology
- Voice Disorders
Background:
- Arytenoid dislocation (AD) presents diagnostic and therapeutic challenges.
- Identifying factors for voice recovery post-reduction is essential for patient management.
Purpose of the Study:
- To identify preoperative prognostic factors for voice recovery after closed reduction for AD.
- To develop a simple risk scoring tool for predicting voice outcomes.
Main Methods:
- Retrospective study of 128 patients with AD undergoing closed reduction.
- Voice outcomes assessed using the GRBAS scale at 1 month post-intervention.
- Logistic regression used to identify predictors; a scoring model was developed and validated.
Main Results:
- Delayed intervention ( >29 days) and nonintubation-related etiology were linked to poorer voice outcomes.
- A three-factor scoring tool (age >58 years, intervention >29 days, nonintubation-related etiology) demonstrated good predictive ability (AUC = 0.785).
Conclusions:
- The developed tool allows for early risk stratification of patients with AD.
- This scoring system utilizes routine clinical variables to aid in individualized patient management.
