Extent of thyroidectomy in nodular thyroid disease.
OBJECTIVE
To find out which procedure was the safest for each indication for operation in diseases of the thyroid gland.


METHODS
Retrospective study.


METHODS
Two teaching hospitals, The Netherlands.


METHODS
599 consecutive patients who had 601 thyroid operations between 1 October 1985 and 1 June 1993.


METHODS
Incidence of complications, particularly postoperative hypocalcaemia and injuries to the recurrent laryngeal nerve.


RESULTS
Accidental injuries to the recurrent laryngeal nerve occurred in 0.7% of the nerves at risk (7/948) and the incidence of permanent hypocalcaemia was 5.2% (31/599). In subtotal procedures (bilateral subtotal thyroidectomy with the remnant left dorsally or total hemithyroidectomy combined with subtotal hemithyroidectomy on the other side with a remnant left at the upper pole) the rate was 11/390 (2.8%) compared with 18/525 (3.4%) after total resections. The corresponding numbers of accidental injuries to the recurrent laryngeal nerve were 2 and 4.


CONCLUSIONS
Total thyroidectomies are more likely to be done for malignant disease, so the slightly higher complication rates probably reflect the nature of the disease, which requires more radical resection. Both subtotal procedures can be done with comparable low morbidity.
