Reoperative thyroid surgery had been denied for fear of increased major complications such as recurrent laryngeal nerve injury and hypoparathyroidism over the past years. However, minimal morbidity and low rates of complication of repeated
thyroid
operations were reported by recent studies. We then collected 35 cases of repeated thyroid surgery at the Department of the General Surgery of Hanyang University Hospital from June 1990 to Juen 1995 with review of articles.
@ES The results were as follows:
@EN At initial operation, Malignancy were 23 cases, sixteen cases of these 23 malignant cases wee not detected malignant findings at various preoperative evaluations including fine needle aspiration cytology, radiologic studies, and other
laboratory
values, even frozen section diagnosis. These 16 cases undergone completion thyroidectomy. Other 7 cases of malignant diseases undergone reoperation because of recurrence of thyroid cancer or suspicions of recurrence after initial operations. Six
benign
cases at the initial operations. 1 case was reported to reveal occult papillary carcinoma.
To reduce the risk of the complications, we made efforts to identify parathyroid glands completely. but hen the injury o parathyroid glands were suspicious, autotransplantation of parathyroid glands were performed. The technique of capsular
dissection
was employed t minimize the injury of vascular pedicles of parathyroid glands while protecting recurrent laryngeal nerve from injury. Minor bleedings along recurrent laryngeal nerve were controlled with bipolar electrocautery to avoid injury of
adjacent
structure.
In this study, permanat nerve injury of hypoparathyroidism was not reported. but, 1 case of transient nerve injury and 3 cases of transient hypoparathyroidism were occured.
Now, Reoperative thyroid surgery can recommend without fear of complications and morbidity.
