Outcomes and complications of thyroid surgery: retrospective study.
OBJECTIVE
To study the outcome and complications of thyroid surgery.


METHODS
Retrospective study.


METHODS
Regional hospital, Hong Kong.


METHODS
Three hundred and twelve patients (266 women and 46 men) underwent thyroid surgery between January 1994 and December 1999.


METHODS
Complications of thyroidectomy for various thyroid diseases according to surgical technique used.


RESULTS
Capsular dissection gradually became a more popular surgical technique: 33% and 58% in the first and second halves of the study period respectively (P<0.001). The overall rate of permanent vocal cord palsy was 2%. Near-total thyroidectomy became the preferred surgical treatment for toxic goitre over the study period. The incidence of recurrent hyperthyroidism was reduced from 21% to 7% (P>0.1, not significant). The incidence of hypoparathyroidism was approximately 30% after thyroidectomy for cancer.


CONCLUSIONS
Capsular dissection is increasingly utilised in thyroid surgery. Low complication rates can be achieved after thyroidectomy for benign diseases. Hypoparathyroidism, however, is a relatively common complication after surgery for thyroid cancer.
