“…The prevalence of arytenoid adduction asymmetry was 37.1 per cent. 3 In that study, the presence of vocal symptoms did not correlate with the prevalence of arytenoid adduction asymmetry. Husseini et al observed a 50 per cent prevalence of arytenoid adduction asymmetry in a group of healthy singers.…”

“…According to our study, the incidence of overriding arytenoids showed a male predominance with a male-to-female ratio of 1.06:1. Hamdan et al and Husseini et al ., 2,3 discovered a male-to-female ratio of 2:1 in their study on arytenoid asymmetry. In the study on arytenoid adduction asymmetry in opera singers, Clarós et al .…”

“…Corniculate cartilage is attached to the top of arytenoids by fibrous connections, whereas cuneiform cartilage is embedded in aryepiglottic folds anterior and superior to corniculate tubercles. 3 The asymmetry in the position of cuneiform-corniculate complex of either side reflects the asymmetry in the movements of arytenoids over the cricoid facet. Arytenoid asymmetry can manifest as the anterior positioning of cuneiform cartilages, overlapping posture of corniculate cartilages and sharpening of the aryepiglottic fold.…”

“…Adequate voice production requires the medial approximation of vocal folds and their proper vertical and horizontal alignment. 3,4 If one arytenoid is anterior to the other during adduction, the vocal fold will become less tense with more pliable tissue and at a lower position than the other vocal fold, resulting in disequilibrium and abnormal vibration. Arytenoid adduction asymmetry is not a rare entity in patients presenting in a laryngology clinic.…”

Objective This study aimed to assess the incidence and severity of arytenoid adduction asymmetry in normophonic speakers and to identify related demographic characteristics. Method A retrospective observational clinical study on normophonic patients was conducted. Videos of flexible laryngoscopy of the study group (aged 18 to 45 years) were reviewed. Arytenoid adduction asymmetry, if present, was graded as mild (grade 1), moderate (grade 2) and severe (grade 3). Results Video recordings of 347 normophonic patients were analysed. The total prevalence of arytenoid adduction asymmetry was 36.4 per cent, with a predominance in males and on the right side. Right-sided predominance was statistically significant (p < 0.01). A total of 60.3 per cent of patients with arytenoid adduction asymmetry had only mild asymmetry, whereas 34.9 per cent had moderate asymmetry. Only 4.8 per cent showed severe asymmetry. Conclusion Arytenoid adduction asymmetry is found in more than one third of the normophonic population, has significant right-sided preponderance and was more common in males.

The purpose of this paper is to describe a series of patients who have undergone medialisation thyroplasty (with or without arytenoid adduction) at our centre with respect to demographics, aetiology for unilateral vocal fold paralysis, pre- and postoperative maximum phonation time, amount of anterior and posterior medialisation required and complications. A comparative analysis with international studies was also performed. A retrospective analysis was performed on 67 patients, who underwent medialisation thyroplasty at our centre from August 2008 to August 2014. All the medialisation thyroplasty were performed using Netterville's technique. The average anterior medialisation needed was 2.25 mm (SD 1.05 mm) while the average posterior medialisation needed was 6.75 mm (SD 1.79 mm). Our study is the first to determine the amount of anterior and posterior medialisation needed in the Indian population. Mean anterior and posterior medialisation required was found to be the same, regardless of the age, gender of the patient and side of surgery.
