[The role of identification of the recurrent laryngeal nerve in thyroid surgery].

Recurrent laryngeal nerve paralysis in the most serious complication of thyroid surgery. Five-hundred and sixty eight-consecutive operations for benign disease of the thyroid were retrospectively analyzed. Bilateral identification of the inferior laryngeal nerve was performed in 447 cases, whereas in 121 patients the identification was unilateral. The rate of primary postoperative vocal cord paralysis was 3.7% and permanent palsy rate was 0.8%. Present results compared with those of Literature confirm that recurrent nerve paralysis is a less frequent complication when the nerve is routinely identified and correctly prepared.
