OBJECTIVES
To evaluate the prognostic value of the posterior cricoarytenoid (PCA) muscle atrophy observed on neck computed tomography (CT) in patients with unilateral vocal fold paralysis.
METHODS
CT images of 87 subjects with unilateral vocal fold paralysis (UVFP) were evaluated to analyze the PCA muscle atrophy and to measure the severity of the PCA muscle atrophy in semi-quantitative manner. The grading of the PCA muscle atrophy was compared with the recruitment pattern of laryngeal electromyography (LEMG) and restoration of vocal fold movement.
RESULTS
The PCA muscle was identifiable on CT in 73 subjects. Using the PCA muscle atrophy as an indicator of UVFP, we correctly predicted the paralysis in 69 (94.5%). Grade of the PCA muscle atrophy is significantly correlated with recruitment pattern of LEMG. If the positive result is defined as the PCA muscle showed moderate to severe degree of atrophy, we could predict the persistent UVFP in 88% of patients.
CONCLUSIONS
PCA muscle atrophy identified on CT scan in patients with UVFP, is associated with low rates of return of mobility in the affected vocal fold.
目的
评估单侧声带麻痹患者颈部计算机断层扫描（CT）观察到的环杓后肌（PCA）萎缩的预后价值。
方法
对 87 例单侧声带麻痹（UVFP）患者的 CT 图像进行评估，以分析 PCA 肌肉萎缩，并对 PCA 肌肉萎缩的严重程度进行半定量分析。将 PCA 肌肉萎缩分级与喉肌电图（LEMG）募集模式和声带运动恢复进行比较。
结果
73 例患者 CT 可识别 PCA 肌。使用 PCA 肌肉萎缩作为 UVFP 的指标，我们正确预测了 69 例（94.5%）麻痹。PCA 肌肉萎缩的程度与 LEMG 的募集模式显著相关。如果将阳性结果定义为 PCA 肌出现中重度萎缩，则我们可以预测 88%的患者存在持续性 UVFP。
结论
在单侧声带麻痹患者的 CT 扫描中发现的 PCA 肌肉萎缩与受累声带运动恢复的低概率相关。
