Total thyroidectomy or lobectomy in benign nodular disease of the thyroid: changing trends in surgery.

METHODS

Over a 23-month period (January 1994-December 1995) in the era of fine needle aspiration (FNA), 344 thyroid surgery operations were performed for benign diseases of the thyroid. Of these 55 total thyroidectomies or lobectomies were evaluated. Mean age was 43.6 + 9.7 and the female/male ratio was 47/8 (5.8). All cases were operated on with the consensus of the surgery + endocrinology + pathology council according to a protocol based on FNA, thyroid function tests, scintigraphy and ultrasound. Suspected FNA or suspected nodules during the surgery were verified by frozen section also. Of these 55 benign nodules, 7 (12.7%) had total bilateral, 48 (87.3%) unilateral lobectomies.

RESULTS

Postoperatively 3 cases (5.8%) of seroma, one transient hypoparathyroidism (1.8%) and one unilateral vocal cord paralysis (1.8%) were seen as complications.

CONCLUSIONS

In our center, FNA cytology has been a routine procedure since 1992. Surgery for benign thyroid disease has been reduced 50% since than. This study was started after two years of the FNA procedure. Resident nodules are the most common cause of recurrence in nodular thyroid disease, so some cases need radical surgery when it is decided to operate. Morbidity of surgery for recurrent disease is unacceptably high and is comparable to lifelong supplement therapy.
