Abstract
Introduction

Otolaryngologists commonly observe asymmetrical movements of the arytenoid cartilages, but few authors have described the clinical implications of this asymmetry, especially in singers.

Objectives

The aim of this study was to determine the epidemiological and clinical characteristics of arytenoid asymmetry in adduction in a group of healthy opera singers and to evaluate the impact of this asymmetry on the voice.

Patients and methods

The medical charts and laryngeal video recordings of 245 healthy opera singers were retrospectively reviewed. Arytenoid asymmetry was defined in relation to the position of the corniculate cartilages, cuneiform cartilages and aryepiglottic angle.

Results

The subjects had a mean age of 38.54 years (range: 18 to 85 years) and presented a male-to-female sex ratio of 1.02. About 5% of subjects had a history of smoking. The most common vocal symptoms were occasional dysphonia (4%), followed by vocal fatigue (2%) and pharyngeal dryness (2%). Arytenoid asymmetry was slightly more common in males (50.6%) and predominantly affected the right side (64.5%). The most common form of asymmetry was cuneiform asymmetry (37.5%), followed by aryepiglottic angle asymmetry in 33.1% of cases and corniculate asymmetry in 29.4% of cases. Mild asymmetry was observed in the majority of cases. No correlation was observed between arytenoid asymmetry and vocal symptoms.

Conclusion

Almost one out of two singers was likely to present arytenoid asymmetry in adduction. The presence of this asymmetry does not appear to be correlated with any vocal symptoms.
