Total Thyroidectomy for Non-Malignant goiter Javed Iqbal, FCPS,FRCS Professor of surgery Quaid-e-Azam Medical College, Bahawalpur
Total thyroidectomy is the procedure of choice for thyroid malignancy
Commonly performed procedures for non-malignant thyroid: Lobectomy Lobectomy with isthamectomy Sub-total thyroidectomy Total Thyroiectomy
Sub-total thyroidectomy is commonly performed because: It is thought that it is associated with low incidence of RNL damage It is thought that the chances of parathyroid damage is less Of the fear that total thyroidectomy will need permanent replacement therapy It is easier to perform then total thyroidectomy
Problems with lesser resection Significant chances of recurrence (up to 23% in MNG) Small but Significant number of MNG have been found to have tiny foci of Malignancy Thyrotoxicosis can also reoccur and specially the ophthalmopathy may stay or even progress after lesser resection
The mid-term freedom rate from thyroid nodulerecurrence or parenchymalirregularity after lobectomy for solitary nodule of the thyroid is unsatisfactory.
Theodore Kocher performed thefirst total thyroidectomy for MNG with very good results andthought it to be the procedure of choice in 1909 mortality less than 0.18% minimal risk to RNL and Parathyroids
He, however abandonedthis procedure due to post- operative hypothyroidism As the thyroid extract was made much later Thyroxine was available in 1913

Total thyroidectomy is now the preferred option for the surgical management of Graves disease," ANZ Journal of Surgery, Volume 72 Issue 5 Page 321 - 2002 Total thyroidectomy will remove the target organ for the immune response in patients with hyperthyroidism and the risk of toxic ophthalmopathy is minimised. Lastly, the risk of recurrent disease is eliminated.

Acceptable results RLN peresis 2.4% RNL damage 0.8% Transient hypocalcaemia 4.2% Long standing Hypocalcaemia 1.4% These results are not different from patients who underwent lesser resection studies
TOUCH WOOD NO RLN damage 3.7% transient Hypocalcaemia 2 patient with long standing Hypocalcaemia
Conclusions No chances of recurrence Lesser resection has no influence on post- operative thyroxine therapy Chances of missing a focus of malignancy is eliminated. The total resection has better effect of progression of Ophthalmopathy in Toxic goiter
Conclusions With capsular dissection technique the incidence of damage to RLN and Parathyroids is comparable with that of sub-total resection
