HYPOTHESIS: Recurrent @entity2895 after thyroidectomy can be unrecognized without routine laryngoscopy, and @entity1 have a good potential for recovery during follow-up. DESIGN: A prospective evaluation of vocal cord function before and after thyroidectomy. Periodic vocal cord assessment was performed until recovery of cord function. Persistent @entity3746 for longer than 12 months after the operation was regarded as permanent. SETTING: A university hospital with about 150 thyroid operations performed by 1 surgical team per year. @entity1 : From January 1, 1995, to April 30, 1998, 500 consecutive @entity1 (84 males and 416 females) with documented normal cord function at the ipsilateral side of the thyroidectomy were studied. MAIN OUTCOME MEASURES: Vocal @entity912 after thyroidectomy. RESULTS: There were 213 unilateral and 287 bilateral procedures, with 787 nerves at risk of injury. Thirty-three @entity1 (6.6%) developed postoperative unilateral @entity912 , and 5 (1.0%) had recognizable @entity16 during the operations. Complete recovery of vocal cord function was documented in 26 (93%) of 28 @entity1 . The incidence of temporary and permanent @entity3746 was 5.2% and 1.4% (3.3% and 0.9% of nerves at risk), respectively. Among factors analyzed, surgery for malignant @entity5 and recurrent @entity13209 was associated with an increased risk of @entity129 . Primary operations for benign @entity5651 were associated with a 5.3% and 0.3% incidence (3.4% and 0.2% of nerves at risk) of transient and @entity129 , respectively. CONCLUSIONS: Unrecognized recurrent @entity3746 occurred after thyroidectomy. Thyroid surgery for @entity5 and recurrent @entity13209 was associated with an increased risk of permanent recurrent @entity16 . Postoperative vocal @entity602 recovered in most @entity1 without @entity16 .
