Transient Aphonia After Mediastinoscopy.

The most common adverse event after cervical mediastinoscopy is recurrent laryngeal nerve (RLN) injury, which has an incidence of 0.6% [1]. We report the case of a 68-year-old man with non-small cell lung cancer (NSCLC) who experienced transient bilateral vocal cord paralysis after mediastinoscopy, which manifested in complete aphonia. This patient's ability to maintain his airway was carefully followed up, but neither endotracheal intubation nor tracheostomy was required. The vocal cord paralysis resolved without intervention after 5 hours. To our knowledge, this is the first reported case in which bupivicaine used at the end of a cervical mediastinoscopy diffused through the freshly dissected planes to paralyze both RLNs along the tracheoesophageal grooves.
