[Incidence of recurrent nerve paralysis in personal cases of thyroid surgery]

The authors review their series of thyroid operations, totaling 383 cases in the last seven years. In that series the incidence of recurrent nerve lesions leading to permanent sequels was 1.07% (all treated without surgical preparation of the nerve); an additional 0.53% of the patients developed transient paralysis of the recurrent nerve--of which the authors discuss the possible etiology. The authors conclude by stating the need for careful recognition of the recurrent nerve in all surgical procedures involving the thyroid gland, except some enucleo-resections; they confirm the importance of branches of the inferior thyroid artery and the inferior horn of the thyroid cartilage as reference points.
