OBJECTIVES: To look at the incidence of arytenoid asymmetry in a group of healthy singers and to investigate whether the asymmetry correlates with posture, neck tension and glottal attack.
MATERIALS AND METHOD: The medical records and video recordings of 42 singers were reviewed retrospectively. Posture, neck tension and glottal attack were evaluated in relation to arytenoid asymmetry during adduction.
RESULTS: The number of singers was 42, with a male-to-female ratio of 2:1. The age range was 16-38 years, with a mean of 24±4.13 years. The total prevalence of arytenoid asymmetry was 50%, with a predominance in males and on the right side. The most common asymmetry was that of the cuneiform cartilages, accounting for 40.5% of the total sample and 81% of the total asymmetries. There was no correlation between arytenoid asymmetry and either posture, neck tension or glottal attack (p=0.343, 0.489 and 0.945, respectively).
CONCLUSION: One out of 2 singers is likely to have arytenoid asymmetry during adduction. The presence of asymmetry does not correlate with posture, neck tension or glottal attack.
