Relationship Between Laryngeal Electromyography and Video Laryngostroboscopy in Vocal Fold Paralysis

Arytenoid asymmetry: Is it the most predictive parameter for arytenoid adduction in unilateral vocal fold paralysis?

“…A RLN injury is the most common traumatic neurolaryngological lesion according to literature. 25 In our study, although no statistically significant inter-group difference was identified with respect to aetiology, idiopathic cause (50 per cent) in group 1 and surgical trauma (55.6 per cent) in group 2 were the most commonly identified causes. Thyroidectomy and skull base surgery, accounting for 48 per cent and 28 per cent, respectively, of cases in the surgical trauma sub-classification in group 2, were seen most frequently.…”

“…24 Comparable results were noted in studies by McCulloch et al and Al-Khtoum et al 12,26 Maamary et al found that RLN lesions were more commonly (not in all cases) associated with a laterally displaced paralysed vocal fold. 25 In contrast, Woodson, in her study comparing the glottic configuration in patients with unilateral vocal fold paralysis due to lesions of either the RLN or the vagus nerve, concluded that vagus nerve lesions had a statistically insignificant tendency for a more lateral vocal fold position. 27 Similarly, McCulloch et al found that more than 50 per cent of those requiring medialisation thyroplasty plus arytenoid adduction had surgically induced nerve injury at the level of the skull base (i.e.…”
