Abstract

Unilateral vocal cord paralysis (UVCP) is not uncommon and can be due to various causes such as iatrogenic injuries, neoplasm or idiopathic. Damage to vagus nerve and its recurrent laryngeal nerve branch may paralyse the laryngeal muscles causing dysphonia, breathiness, vocal fatigue and aspiration. We reported a rare case of left UVCP where the paralysis was caused by the stretching of left recurrent laryngeal nerve after the patient had undergone right pneumonectomy several years earlier due to lung fungal infection. Patient underwent injection laryngoplasty at our centre and her dysphonia improved temporarily.
