Laryngeal trauma due to endotracheal intubation is probably more common than appreciated, however, given that symptoms of sore throat and hoarseness after most operations are generally self-limiting, this is not usually a major cause of concern. On the other hand, postoperative vocal symptoms may be a major cause of anxiety after thyroidectomy, due to fear of damage to the recurrent laryngeal nerve or the external branch of the superior laryngeal nerve (SLN). Laryngeal trauma without impairment of vocal fold function has been reported to be a significant cause of vocal symptoms after thyroid surgery. However, no previously published study has attempted to correlate post-thyroidectomy vocal symptoms or signs of laryngeal trauma with ETT size.
