Objectives:
To analyze the prognostic relevance of mucosal waves (MWs) for recovery of unilateral vocal fold paralysis (UVP).
Methods:
The charts and stroboscopic examinations of 100 consecutive patients with a complete UVP were reviewed retrospectively. All had a minimal (estimated <3 mm) mucosal gap on stroboscopy. A positive or negative MW on the paralyzed vocal fold was associated with complete recovery to full adduction and abduction. All patients were followed for at least 12 months.
Results:
Causes of the paralysis were iatrogenic/traumatic (n = 82), malignancy associated (n = 10), and idiopathic (n = 8). In patients with positive MW at diagnosis (n = 80), the chance of recovery of unilateral vocal fold paralysis was 91.25%, whereas the chance of recovery with a negative mucosal wave (n = 20) was only 10%.
Conclusion:
Positive MWs in stroboscopy are a predictor for recovery of (iatrogenic/traumatic) unilateral vocal fold paralysis and should be used in routine diagnostic assessment.
